Conversations on Climate: Paul Wignall says climate crisis is nothing new

Climate Change: We’ve Been Here Before
by Paul Wignall

The world’s climate is always changing and always has. Even during the past few centuries we have seen substantial variations, but only recently have we begun to blame ourselves for them. But how much natural variability is there, and just how extreme can climate change be? To gain some longer-term perspective on the climate’s variability we can look back through geological time, particularly at catastrophic events known as mass extinctions. In my recent book, The Worst of Times, I focus on an 80 million year interval when life on Earth suffered one disaster after another. These catastrophes included the Permo-Triassic mass extinction, the worst crisis that life has ever faced. It is not very reassuring to find that these extinctions all coincide with intervals of rapid global warming.

So, are we all going to hell in a hand basket? Well, probably not just yet. The story from the past is much more nuanced than this and I believe there is substantial hope that all is not so bad today. The reason is that the worst 80 million years happened a long time ago and more recently (in the past 100 million years) things have got a lot better. At one time all the world’s continents were joined together into a single supercontinent called Pangea. This seems to have created a global environment that was very fragile. Every time there was a phase of giant volcanic eruptions in Pangea, climates changed rapidly, the oceans stagnated and life began to suffer. The cause seems to be not the actual lava flows themselves, although these were very large, but the gases that bubbled out of them, especially carbon dioxide, everyone’s (not so) favorite greenhouse gas. As I explain in my book the effects of these gases on climate and oceans changed global environments in a disastrous way. Rapid increases in global temperature were part of the story and the results were some of the hottest climates of all time. The results for life were profound; dominant groups went extinct and new groups appeared only to have their brief hegemony terminated by the next disaster. By the time these waves of extinction were over the dinosaurs were the newest kids on the block. They went on to thrive and get very large whilst scurrying around at their feet were a group of small furry creatures. These were the mammals and they would have to wait a long time for their turn.

Dinosaurs were the dominant animals on Earth for over 140 million years and it is often thought that they were somehow competitively successful but I think they were just very lucky. They appeared at a time when the Earth was rapidly getting better at coping with climatic changes caused by giant volcanism. There were plenty of episodes of large-scale eruptions during the time of the dinosaurs and none caused major extinctions. The key thing was that Pangea was splitting up and separate continents were forming – the familiar continents of today’s world. Such a world seems better able to cope with rapid increases in atmospheric gases because feedback mechanisms are more effective. In particular rainfall is more plentiful when the continents are small and nowhere is too far away from the sea. Rain scrubs the atmosphere and thus alleviates the problems.

However, the $64,000 question is how quickly this feedback can happen. The world seems better at doing this today than it was in deep time but maybe we are adding the carbon dioxide too fast to our atmosphere, maybe we are swamping the system? This is a hard question to answer, we’re not sure how much gas came out during the giant eruptions of the past and so it’s hard to directly compare with the present day pollution rates. What we do know is that past mega-eruptions have been remarkably damage-free. For over 100 million years, our world has been a benign place.

Oh, except for a remarkably large meteorite impact that was bad news for the dinosaurs, but that’s another story.

Conversations on Climate: Economists consider a hotter planet on PBS Newshour

NEW climate picIn Climate Shock, economists Gernot Wagner and Martin Weitzman tackle the likely prospect of a hotter planet as a risk management problem on a global scale. As 150 world leaders meet in Paris for the UN Conference on Climate Change, both took the time to speak to PBS Newshour about what we know and don’t know about global warming:


Everyone is talking about 2 degrees Celsius. Why? What happens if the planet warms by 2 degrees Celsius?

Martin L. Weitzman: Two degrees Celsius has turned into an iconic threshold of sorts, a political target, if you will. And for good reason. Many scientists have looked at so-called tipping points with huge potential changes to the climate system: methane being released from the frozen tundra at rapid rates, the Gulfstream shutting down and freezing over Northern Europe, the Amazon rainforest dying off. The short answer is we just don’t — can’t — know with 100 percent certainty when and how these tipping points will, in fact, occur. But there seems to be a lot of evidence that things can go horribly wrong once the planet crosses that 2 degree threshold.

In “Climate Shock,” you write that we need to insure ourselves against climate change. What do you mean by that?

Gernot Wagner: At the end of the day, climate is a risk management problem. It’s the small risk of a huge catastrophe that ultimately ought to drive the final analysis. Averages are bad enough. But those risks — the “tail risks” — are what puts the “shock” into “Climate Shock.”

Martin L. Weitzman: Coming back to your 2 degree question, it’s also important to note that the world has already warmed by around 0.85 degrees since before we started burning coal en masse. So that 2 degree threshold is getting closer and closer. Much too close for comfort.

What do you see happening in Paris right now? What steps are countries taking to combat climate change?

Gernot Wagner: There’s a lot happening — a lot of positive steps being taken. More than 150 countries, including most major emitters, have come to Paris with their plans of action. President Obama, for example, came with overall emissions reductions targets for the U.S. and more concretely, the Clean Power Plan, our nation’s first ever limit on greenhouse gases from the electricity sector. And earlier this year, Chinese President Xi Jinping announced a nation-wide cap on emissions from energy and key industrial sectors commencing in 2017.

It’s equally clear, of course, that we won’t be solving climate change in Paris. The climate negotiations are all about building the right foundation for countries to act and put the right policies in place like the Chinese cap-and-trade system.

How will reigning in greenhouse gases as much President Obama suggests affect our economy? After all, we’re so reliant on fossil fuels.

Gernot Wagner: That’s what makes this problem such a tough one. There are costs. They are real. In some sense, if there weren’t any, we wouldn’t be talking about climate change to begin with. The problem would solve itself. So yes, the Clean Power Plan overall isn’t a free lunch. But the benefits of acting vastly outweigh the costs. That’s what’s important to keep in mind here. There are trade-offs, as there always are in life. But when the benefits of action vastly outweigh the costs, the answer is simple: act. And that’s precisely what Obama is doing here.

Conversations on Climate: Victor W. Olgyay on Design and Ecology’s Interconnection

Connecting Buildings to Address Climate Change
by Victor W. Olgyay

“We are not all weak in the same spots, and so we supplement and complete one another, each one making up in himself for the lack in another.”
Thomas Merton, No Man is an Island

In Pope Francis’ recent visit to the US, he referred to several interesting touchstones in America’s spiritual history, including Thomas Merton. Merton was a prolific writer, and often emphasized the importance of community and our deep connectedness to others as a nurturing aspect of spiritual life. The importance of connectedness is not only true of spirituality, but also applies to ecology, an idea we continue to relearn. We cannot throw anything out, because our discard comes back to us in the water we drink, the food we eat, or in the air we breathe. Our society is intimately connected; we all depend on the same resources to survive.

As the world’s leaders debate political solutions to our current climate crisis, brought about largely by our neglect of this idea, we can look to some very practical solutions within our built environment to protect and enhance resilient communities. In buildings, these broader connections to community exist as well. Buildings have traditionally emerged from context, been built out of local materials, fit into the contours of the landscape, and made use of the local climate to help heat and cool the structures. Almost inevitably, these buildings show a climatic response, drawn from the genus of place, mixed with human inventiveness. Between people and place a dialogue is evoked, a call and response that started long ago, and continues to evolve today.

This conversation has a science to it as well. In the mid 20th century many architects dove deep into the rationality of design, rediscovering how buildings can be designed to optimize their relationship to people, climate and place. Bridging technology, climatology, biology and architecture, the science of bioclimatic design was given quantitative documentation in Design with Climate, the 1963 text recently republished by Princeton University Press. The interdisciplinary approach to design that book describes remains the fundamental approach to designing high performance buildings today.

Integrated building design connects across disciplines.

Integrated building design connects across disciplines.

But today’s high performance buildings are often functionally isolated from our neighbors, from our community. Rather than emphasize connectivity, we have built our utility network on the idea that our buildings are at the consuming end of a wire. We aspire to make our buildings independent, but objectively we remain largely interdependent. By recognizing our commonality, we can reimagine our activities, so our buildings use connectivity to provide services that benefit the larger community as well as the building owner or occupant.

High performance solar powered buildings can use the electric utility grid to achieve net zero energy use over the course of a year. When building PV systems generate more electricity then they need, they can push it back into the grid, and when they need electricity, they can pull it from the grid, in essence, using the electrical grid as if it were a large battery.

While this is quite reasonable from a building end user perspective, what happens if we are drawing energy when the electricity is in great demand and pushing electricity onto it when there is already an excess of electricity? Looking at the system from the grid perspective is a different point of view. High performance buildings can make utility electricity problems worse.

By intelligently connecting buildings we can respond appropriately to utility grid needs, and provide services. To some extent this has been happening for many years in the form of “demand response” where building owners opt to reduce their power consumption when the utility is stressed in meeting demand. In turn, building owners receive reduced electricity charges.

But this is only the beginning. When we aggregate neighborhoods of buildings, we can provide a wide variety and quantity of services to the grid. In addition to demand response, buildings can (thanks to on site solar electricity generation) supply low carbon electricity to the grid. Buildings can shift loads, to use electricity when there is an over supply. Buildings (using batteries or thermal systems) can store energy for use later. Portfolios of buildings can even provide voltage regulation in useful quantities.

These ancillary products of high performance buildings are of great value economically to both the building owner and to the utility providing electricity and electricity distribution services. They are worth money, and a building that has always carried a utility operating cost can now be designed to have an operating income. And perhaps even more importantly, buildings communicating with the grid can help the grid run more smoothly, and by decarbonizing the electricity reduce the pollution and greenhouse gas emissions associated with providing utility services to us all.

Connecting buildings to act as an asset to the utility grid turns our current “end user” paradigm on its head. Individual projects can multiply their positive impact by increasing connectedness. As more of us coordinate with electrical utility systems, we have a stronger base of resources, a more resilient electrical grid, and more sources of income.

The bioclimatic design approach described in Design with Climate now has a renewed urgency. As we design our new buildings and redesign our existing buildings to purposefully engage with their context and climate and community, we can readily reduce building energy use and emissions at marginal cost. Connecting with climate, and intelligently connecting with the utility grid empowers buildings to have a positive environmental impact. With the issue of climate change looming ever sharper, the design community must recognize their deep connection to the climate issue, and take responsibility for moving the design professions and society forward to a solution.

In our commonality we find a larger, critical context that is set by our interdependence. Indeed, as Merton noted, in community we complete one another, and recognize our common home.

Conversations on Climate: Victor W. Olgyay on Design for Climate

NEW climate pic

Design with Climate is Design for Climate
by Victor W. Olgyay

climate change 2Our environmental crisis is real, and it is of our own creation. It is shocking that we humans are intentionally destroying the foundations of our existence, fouling our nest beyond repair. And we appear incapable of stopping ourselves from continuing to further worsen the problem.

Perhaps the issue is not irredeemable. After all, the climate crisis has had a long, slow burn. It has been a hundred years in the making, and has had the contribution of millions of individuals who have been polluting in the name of progress.

Now, in 2015 we are aware of what the uncoordinated actions of 7.3 billion people working for progress results in. We understand the origins of the ever-increasing carbon dioxide in the atmosphere. And we can both see the path forward, and we can design the path that we prefer.

Globally, buildings are the largest end use energy sector. We need to take dramatic steps today to address the global climate crisis, and that requires improving the energy performance of existing and new buildings. By doing this we will be able to shift economically to a renewable, low carbon energy supply.

We can reduce energy use in new and existing buildings dramatically and we can accomplish much of this through low and no cost measures. Simply designing buildings to work with local climatic conditions can reduce energy use by 50 percent or more. Design with Climate, a book written over 50 years ago, and recently republished by Princeton University Press, shows exactly how to do that. In essence, bioclimatic design information tells us how to shade our windows and walls during overheated periods, and to let in the sun’s warmth in when it is desirable. We can use daylight to illuminate vast amounts of interior space, and ventilate buildings with the wind, rather than fighting it. These ideas and many more result in sensible, responsible design, intelligent use of resources, and can result in beautiful, comfortable buildings.

: Designing with Climate makes buildings more comfortable while using less energy.

Designing with Climate makes buildings more comfortable while using less energy.

Since Design with Climate was written in 1963, several things have happened that make this even easier. We have more effective building insulation systems, which dramatically reduce heat loss and gain. We have better windows, and better techniques for building to reduce air and moisture infiltration. And we have sophisticated computer energy modeling techniques that accurately predict how buildings will preform before we build them, so building performance can become an integral part of building design.

And one more thing: we have that environmental crisis I started with. When Design with Climate was first published in 1963, the amount of carbon dioxide in the atmosphere was 320 parts per million (ppm), and today it is over 400ppm. In 1963 Rachael Carson had just written Silent Spring, and the environmental movement was nascent. Today the polar ice caps are melting, and global warming is threatening our very existence.

climate change 1We are now building extremely low energy buildings, zero energy buildings, and even buildings that produce more energy then they consume. Retrofitting existing buildings to use less energy, and building new superefficient structures paves the way for our renewable energy powered future, and combats climate change.

We must design not only with, but also for climate. Building design has implications we must use for our benefit. And through this engaged conversation with nature we can usher in a design solution to our climate crisis. That is true progress that can align millions of people.

Victor Olgyay: Architecture is the cause and solution to climate related problems

design with climatePrinceton University Press has just reprinted Design with Climate: Bioclimatic Approach to Architectural  Regionalism, by Victor Olgyay, more than 50 years after its initial printing in 1963. Design with Climate describes an integrated design approach that remains a cornerstone of high performance architecture.

Victor Olgyay (1910-1970) was associate professor in the School of Architecture and Urban Planning at Princeton University. He was a leading researcher on the relationship between architecture, climate, and energy. His son, Victor W. Olgyay, is an architect and principal at Rocky Mountain Institute and was instrumental in reissuing this book. For this updated edition, he commissioned four new essays that provide unique insights on issues of climate design, showing how Olgyay’s concepts work in contemporary practice. Ken Yeang, John Reynolds, Victor W. Olgyay, and Donlyn Lyndon explore bioclimatic design, eco design, and rational regionalism, while paying homage to Olgyay’s impressive groundwork and contributions to the field of architecture.

Victor W. Olgyay spoke to Molly Miller about Design with Climate then and now.

Did Design with Climate change design when it came out in 1963?

VO: It wasn’t really very popular in the United States when it came out, but it soon became genuinely popular in South America. Our whole family moved to Colombia, South America, so my father could teach bioclimatic design there. He did research with his students using local climate zones and generated very interesting regional designs and published different versions of Design with Climate in Colombia and Argentina. This was in 1967-70. There are still clandestine editions in Spanish and Portuguese floating around, as well as in my fathers’ archives at Arizona State University.

My father died on Earth Day, April 22, 1970. Soon afterwards the 1973 oil embargo began and energy became a serious topic. That’s when Design with Climate caught people’s attention in the US because here was a book showing architects how they could respond to critical contemporary issues. Design with Climate suddenly was adopted in dozens of schools of architecture in the US and became a popular textbook. The broad popularity of the book had to do with Earth Day and with the oil crisis, but in the architecture community it was seen as a keystone helping bridge the emerging environmental architecture movement and analytic regionalism. That’s when it began to affect how architects approach design.

What is bioclimatic design?

VO: My father coined the term “bioclimatic design.” Bioclimatic design uses nature’s energies to harmonize buildings with local conditions. The physics of the environment, such as solar radiation and the convection of wind are employed as formal influences to create a climate balanced design. A diagram in the book shows four interlocking circles: biology, climatology, technology, and architecture. The lines of the circles are soft multi-layered lines, emblematic of the riparian merging of these disciplines. Bioclimatic design takes these disciplines and considers them together. For me this is the approach of a polymath, where when you consider things from different worlds together, you learn something completely new. You have insights you wouldn’t have gotten if they were isolated.

Screen Shot 2015-10-22 at 2.53.49 PM
In this model, people are at the center of the diagram. Biology addresses people’s needs for thermal and visual comfort. Synthesizing these disciplines results in a superior architecture. My father believed architecture’s ultimate purpose is to provide a place for the human spirit to lift, and support the human endeavor.

On a more practical level, a large part of this book is devoted to a design process. What if climate informs the design? How can you optimize nature and apply it to buildings?

VO: What’s really different about this approach is that my father looked carefully at how these fields are inter-related and did the analysis. This process is shown in the book. He took fairly complicated data about climate and made it into manageable design steps. He advocated working with climate to reduce energy use by orientation, shading, natural ventilation etc. In one example, he used wind tunnels with smoke to visualize air currents. Seeing the air currents allows an architect to make adjustments in their design, perhaps slightly moving the edge of an overhang next to a building to optimize natural ventilation.

How is this book relevant today?

VO: Today, more than ever, we have identified architecture as the cause and solution to a large percentage of our climate related problems. It is impossible for us to transition to a low carbon economy without reducing the energy consumption of buildings. To do that, we need to take into account bioclimatic design and Design with Climate shows us how to get that into our lexicon again.

Integrated design has taken off. Today, we have a renaissance of people thinking about green design. Not only do we need to design with climate, we now have to design for a changing climate and address global issues with architecture.

But even though we can say green design is becoming mainstream, the concepts in Design with Climate are still widely overlooked. Let’s take shading as an example. Many ‘green’ architects are still cladding their entire building in glass, which is neither comfortable nor energy efficient and ignores climatic information.

Architects rarely recognize how a building affects people and the environment. It’s surprising to me that architects don’t use climatic information more. It’s a gift to be able to make a space that people find thermally and visually comfortable. That can make an inspired design! There are dire consequences to designing a glass box. It’s critical today for architects to have a modicum of morality in design. This is the awareness that Design with Climate brings. There’s no penalty for your design to work with climate, just benefits.

Has this new edition of Design with Climate been changed or updated?

VO: As an existing book, it seemed classic and I wanted to honor that. So we reprinted the entire original manuscript exactly as it first appeared. But we added some essays to provide contemporary context. Donlyn Lyndon worked with my father on the original research. John Reynolds, professor emeritus at University of Oregon, has been teaching bioclimatic design for 40 years. Ken Yeang, who has been working with ecological design with tall buildings, brings Design with Climate into the 21st Century. These essays each add color and context and show how Design with Climate was a steppingstone to our contemporary architecture.

What does this book mean to you personally and professionally?

VO: I have always been interested in the implications of architecture and form. Our work is important, and can have a positive impact in the world. My father’s book has reached hundreds of thousands of people and encouraged environmental architects. I am very thankful that this book has had that influence. It is an honor for me to assist with this new edition, so this book endures as an inspiration for others to honor the earth, and to support the evolution of the human spirit.

An interview with Paul Wignall: How life on earth survived mass extinctions

Wignall jacketAs scientists ponder NASA’s recent announcement about the likelihood of water and the possibility of life, or extinct life on Mars, Paul Wignall, professor of palaeoenvironments at the University of Leeds, explores a calamitous period of environmental crisis in Earth’s own history. Wignall has been investigating mass extinctions for more than twenty-five years, a scientific quest that has taken him to dozens of countries around the world. Recently he took the time to answer some questions about his new book, The Worst of Times: How Life on Earth Survived Eighty Million Years of Extinctions.

So why was this the worst of times and what died?

PW: For 80 million years, there was a whole series of mass extinctions; it was the most intense period of catastrophes the world has ever known. These extinctions included the end-Permian mass extinction, the worst disaster of all time. All life on earth was affected, from plankton in the oceans to forests on land. Coral reefs were repeatedly decimated, and land animals, dominated by primitive reptiles and amphibians, lost huge numbers of species.

What was responsible for all of these catastrophes?

PW: There is a giant smoking gun for every one of these mass extinctions: vast fields of lava called flood basalts. The problem is how to link their eruption to extinction. The key is understanding the role of volcanic gas emissions. Some of these gases, such as carbon dioxide, are very familiar to us today, and their climatic effects, especially global warming, seem to have been severe.

Why did these catastrophes stop happening?

PW: This is the $64,000 dollar question at the core of The Worst of Times. It seems to be because of a supercontinent. For 80 million years, all continents were united into a single entity called Pangea. This world was extremely bad at coping with rapid global warming because the usual feedbacks involved in removing gases from the atmosphere were not functioning very well. Since then, Pangea has broken up into the familiar multi-continent world of today, and flood basalt eruptions have not triggered any more mass extinctions.

What were the survivors like?

PW: Very tough and often very successful. It takes a lot to survive the world’s worst disasters, and many of the common plants and animals of today can trace their origin back to this time. For example, mollusks such as clams and snails were around before this worst of times, and their survival marks the start of their dominance in today’s oceans.

Are there any lessons we can apply to modern day environmental worries?

PW: Yes and no. Rapid global warming features in all of the mass extinctions of the past, which should obviously give us cause for concern. On the plus side, we no longer live in a supercontinent world. Flood basalt eruptions of the recent geological past have triggered short-lived phases of warming, but they have not tipped the world over the brink.

Paul Wignall at Otto Fiord at Cape St Andrew.

Does this have anything to do with the dinosaurs?

PW: Sort of. Dinosaurs first appear towards the end of this series of calamities and to a great extent they owed their success to the elimination of their competitors, which allowed them to flourish and dominate the land for 140 million years. As we know, their reign was brought to an abrupt halt by a giant meteorite strike – a very different catastrophe to the earlier ones.

What would you say to those who want to know how you can claim knowledge of what happened so long ago?

PW: Geologists have a lot of ways to interpret past worlds. The clues lie in rocks, so mass extinction research first requires finding rocks of the right age. Then, once samples have been collected, analysis of fossils tells us the level where the extinctions happened. This level can then be analyzed to find out what the conditions were like. It’s like taking a sample of mud from the bottom of the ocean and then using it reconstruct environmental conditions. However, not everything gets “fossilized” in ocean sediments. For example, it is very hard to work out what past temperatures were like, and ocean acidity levels are even harder to determine. This leaves plenty of scope for debate, and The Worst of Times looks at some of these on-going scientific clashes.

Book Fact Friday – Microbes

From chapter 2 of Life’s Engines:

One of the biggest ironies in biology is that microbes, the oldest self-replicating organisms on Earth, were among the last to be discovered and have largely been ignored.

Life’s Engines: How Microbes Made Earth Habitable
Paul G. Falkowski
Chapter One

k10440For almost four billion years, microbes had the primordial oceans all to themselves. The stewards of Earth, these organisms transformed the chemistry of our planet to make it habitable for plants, animals, and us. Life’s Engines takes readers deep into the microscopic world to explore how these marvelous creatures made life on Earth possible—and how human life today would cease to exist without them.

Paul Falkowski looks “under the hood” of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains how these miniature engines are built—and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies. Falkowski shows how evolution works to maintain this core machinery of life, and how we and other animals are veritable conglomerations of microbes.

A vibrantly entertaining book about the microbes that support our very existence, Life’s Engines will inspire wonder about these elegantly complex nanomachines that have driven life since its origin. It also issues a timely warning about the dangers of tinkering with that machinery to make it more “efficient” at meeting the ever-growing demands of humans in the coming century.

Book Fact Friday – The Sun

From chapter 3 of The Sun’s Influence on Climate:

The Sun is about midway through its lifetime. At 5765 Kelvin, it is considered a cool star. 4,500,000,000 years ago, it formed from a dust cloud and is now burning its fuel, converting hydrogen into helium. Eventually, this burning will cease and it will end its life as a white dwarf.

The Sun’s Influence on Climate
Joanna D Haigh & Peter Cargill
Chapter 1

k10522The Earth’s climate system depends entirely on the Sun for its energy. Solar radiation warms the atmosphere and is fundamental to atmospheric composition, while the distribution of solar heating across the planet produces global wind patterns and contributes to the formation of clouds, storms, and rainfall. The Sun’s Influence on Climate provides an unparalleled introduction to this vitally important relationship.
This accessible primer covers the basic properties of the Earth’s climate system, the structure and behavior of the Sun, and the absorption of solar radiation in the atmosphere. It explains how solar activity varies and how these variations affect the Earth’s environment, from long-term paleoclimate effects to century timescales in the context of human-induced climate change, and from signals of the 11-year sunspot cycle to the impacts of solar emissions on space weather in our planet’s upper atmosphere.
Written by two of the leading authorities on the subject, The Sun’s Influence on Climate is an essential primer for students and nonspecialists alike.

The First Fossil Hunters by Adrienne Mayor

j9435

In The First Fossil Hunters, Mayor shows us that many mythological creatures of the past, including Griffins, Cyclopses, Monsters, and Giants, are in fact based on creatures that used to exist. The ancients knew that different creatures once inhabited the earth, and they came up with sophisticated theories to explain the fossils they found. These first paleontologists are studied in detail in Mayor’s book.

World Oceans Day 2015

In December 2008, the United Nations passed a resolution officially recognizing June 8th as World Oceans Day. It is organized and coordinated by The Ocean Project, an organization that focuses its efforts on advancing ocean conservation in partnership with zoos, aquariums, and museums around the world. World Oceans Day aims to raise awareness of the current health of the ocean and educate people on the myriad ways that we rely on this complex ecosystem. To learn more about World Oceans Day and their events, visit the website.

If you’d like to learn more about the world’s oceans, Princeton University Press publishes a number of titles on the subject, including Climate and the Oceans, The Extreme Life of the Sea, and The Great Ocean Conveyor.
