A look at past and future climate change in less than a minute

E360 Digest – Yale Environment 360, 2/18/19

For visual learners: Two new videos visualize how drastically global temperatures have changed since 1900–and how they will likely continue to change up to 2100. The visualizations, created by Antti Lipponen of the Finish Meteorological Institute, depict 200 years of climate change in less than a minute…

Climate change and coronavirus: Five charts about the biggest carbon crash

Matt McGrath – BBC News, 5/6/20

We’re living through the biggest carbon crash ever recorded. No war, no recession, no previous pandemic has had such a dramatic impact on emissions of CO2 over the past century as Covid-19 has in a few short months. But even though we will see a massive fall this year, the concentrations of CO2 that are in the atmosphere and warming our planet won’t stabilise until the world reaches net-zero…

America’s renewable energy sources produced more electricity than coal every day for 40 days straight

Jason Murdock – Newsweek, 5/5/20

Renewable sources including solar, wind and hydropower generated more electricity than coal-based plants every single day in April, a new report says. Analysis based on data from the U.S. Energy Information Administration (EIA), said the finding marks a major “milestone” in an energy transition that is now underway…

Unchecked global warming could collapse whole ecosystems, maybe within 10 years

Bob Berwyn – InsideClimate News, 4/8/20

A new study shows that global warming is about to push temperatures beyond the tolerance of thousands of animals at the same time. As some key species go extinct, entire ecosystems like coral reefs and forests will crumble, and some will collapse abruptly, starting as soon as this decade, a new study in the journal Nature warns…

Eleven of 12 hottest years have occurred since 2000, new report warns

Isabelle Gerretsen – UK Independent, 4/22/20

Eleven out of the 12 hottest years to date have all occurred since 2000, according to a new report by the European Union’s climate  monitoring service. 2019 was the hottest year on record for Europe after scorching heatwaves led to record-breaking temperatures in February, June and July, scientists said in the annual European State of the Climate report…

Pandemic Insights Two: Our capacity to sacrifice to contain a global threat

It’s not usually advisable to speak for others, yet I think I know how many climate experts are feeling right now. There’s this particular twinge I feel as a climate advocate: seeing how humans are mobilizing globally and instantaneously to fight the coronavirus yet we’ve been unable–for three decades–to mobilize against the slower-moving yet ultimately more catastrophic and irreversible threat of climate change. For someone deeply engaged in climate facts, this unequal crisis response feels dizzying. And yet, our global action against the pandemic shows that we are capable of massive, lightning-fast change.

I want to talk about our emerging awareness of the scale and speed of change we are capable of in a crisis. I don’t think any of us born after World War II have seen this capacity before, but we are seeing it now. In our country and around the world, hundreds of millions of people have stopped going to work, school, church, social events, and sporting events. Leisure and work travel has been suspended, skies have cleared, traffic jams are gone, classrooms, sports arenas, and concert halls sit empty, and nearly everything considered “non-essential” that requires being with others has stopped. Along with all the tragedy, fear and insecurity of the pandemic, we are also seeing a tremendous capacity for sacrifice, generosity, and change.

Naomi Oreskes, an historian of science at Harvard I’ve long admired, recently spoke with journalist David Green about the lessons of coronavirus that might help humanity respond to climate change. She highlighted the breathtaking sacrifices people are making in response to COVID-19 that were previously unimaginable:

“I think that the crisis brings into sharp relief the difference between “can’t” and “won’t.” We can act, we know how to mobilize expertise, to mobilize technology. And we now see that the American people and people around the world are great at sacrificing. Whereas, it’s always been said that the problem with solving climate change is that people are not willing to sacrifice.”

And here’s the kicker:

“People not only can, but will, sacrifice, if they’re given the right information and leadership.” (emphasis mine)

This is the hopeful heart of her message. Because, as Oreskes points out, what most people need to sacrifice to solve the climate crisis is a whole lot less than what they are sacrificing during this pandemic. Decarbonizing quickly is achievable: we have the technology, resources, and policy tools to do it without widespread harm. In fact, most experts believe a well-organized clean energy transition will lead to widespread health benefits, a surge in good jobs and economic benefits for most people.

So as we navigate this crisis, let’s keep our eye on this prize: an economic recovery that builds clean energy and decarbonizes our economy at the same time. To get there, Oreskes says, we need two key ingredients: the right information and leadership, and breaking the control the fossil fuel industry has over our country and our politics. If the last four months illustrate anything, it’s that once we commit, we can get there quickly.
