Biden links climate action with economic stimulus, methane emissions climb, tipping points drawing near, the challenge of managed retreat, record high-tide flooding

An article in New York Magazine describes how Joe Biden’s climate plan is being framed as a key part of the economic stimulus the country requires to recover from the pandemic. This is an important and welcome development, as transitioning from fossil fuels requires a major investment, and if we invest in the “business as usual” fossil-fuel-powered economy, our climate goals will be out of reach (the Biden campaign video introduces this plan for a clean-energy revolution and environmental justice). An article in the New York Times describes how climate change and other environmental issues are emerging as a clear difference between the presidential candidates, and Governor Jay Inslee discusses Biden’s climate plan in an interview in New York Magazine.

An article in the New York Times documents that global emissions of methane, a potent greenhouse gas, reached a record high in 2017, driven mainly by leaks from fossil-fuel facilities and emissions from agriculture. The article notes that a given amount of methane produces 86 times more warming than carbon dioxide over a twenty year period. Rob Jackson, a Stanford earth scientist who leads the Global Carbon Project, notes that “if we continue to release methane as we have done in recent decades, we have no chance” to keep global temperature increases to just 2°C. Newsweek reports how scientists are using satellites to measure methane emissions from remote lakes in the Arctic…

climate may be more sensitive than we thought to carbon dioxide, California publishes electric-truck rule, Siberia is as warm as Las Vegas, Democrats release ambitious climate plan, a new endangered species: the 30-year mortgage

The Guardian reports on modeling results from more than 20 institutions compiled for the sixth assessment by the United Nations Intergovernmental Panel on Climate Change, and the news is a bit alarming. Compared with the last assessment in 2014, 25% of the results demonstrate that the sensitivity of the climate to carbon dioxide (e.g., the temperature increase associated with a doubling of CO2 in the atmosphere) is close to 5°C. This is at the high end of previous ranges and, if true, would mean we’ll be lucky to keep global average temperature rise to 2°C even with ambitious emissions reductions. The key factor here is the complex science of clouds. With supercomputers able to run finer scale simulations, and advances in understanding the microphysics of clouds, many models are suggesting that the warming effect of clouds (capturing heat) significantly outweighs their cooling effect (reflecting sunlight).

An article in Grist notes that a green economy must also be a just economy. Transitioning to renewable energy is important, but we also must address the serious inequities in our society to achieve a sustainable outcome. “You can take as many fossil fuels out of the economy as you want and it won’t address the problem that the only American households to accumulate wealth in the 21st century are the wealthiest third, that CEOs are making 287 times the salary of the average worker, or that white families’ median wealth is about 10 times that of black families.”

The California Air Resources Board (CARB) just passed the nation’s first electric-truck standard. The Advanced Clean Trucks (ACT) rule, which will help put more electric trucks on the road, is a major step in reducing air pollution and global warming emissions in California and beyond…
