From the DNC: A Call for Climate Action

Environmentalists are heartened to hear prominent Democrats — Sen. Bernie Sanders (D-Vt.) and Elizabeth Warren (D-Mass.), among others — calling for urgent climate action at the Democratic National Convention (DNC) taking place in Philadelphia. California Gov. Jerry Brown devoted his whole speech to tearing down climate denial. That’s a stark contrast with the recent Republican National Convention (RNC) in Cleveland, where the subject was largely ignored. After all, Republican presidential nominee Donald Trump, Brown’s main target, has called climate change a “hoax,” conjuring a picture of thousands of climate scientists all over the world having quite a laugh.

The party platform documents make the contrast more clear. “Climate change is an urgent threat and a defining challenge of our time,” the Democrats say, pledging an array of actions in support of the The Paris Agreement, moving to clean energy sources and creating jobs in the process. The Republicans reject the agendas of the Kyoto Protocol and the Paris Agreement, demand a halt to U.S. funding of the U.N.’s Framework Convention on Climate Change (UNFCCC) and vow to defeat President Barak Obama in his “war on coal” through the Clean Power Plan.

Key points summarized in the Dems’ platform:

Democrats share a deep commitment to tackling the climate challenge; creating millions of good-paying middle class jobs; reducing greenhouse gas emissions more than 80 percent below 2005 levels by 2050; and meeting the pledge President Obama put forward in the landmark Paris Agreement, which aims to keep global temperature increases to “well below” two degrees Celsius and to pursue efforts to limit global temperature increases to 1.5 degrees Celsius. We believe America must be running entirely on clean energy by mid-century. We will take bold steps to slash carbon pollution and protect clean air at home, lead the fight against climate change around the world, ensure no Americans are left out or left behind as we accelerate the transition to a clean energy economy, and be responsible stewards of our natural resources and our public lands and waters. Democrats reject the notion that we have to choose between protecting our planet and creating good-paying jobs. We can and we will do both.

Study: Freshwater Shortage Will Double Climate Change’s Impact on Agriculture

Experts expect global warming to have a negative impact on crop yields, but shortages of water for irrigation could make for double the trouble, according to a study published yesterday.

As described in ScienceDaily, “given the present trajectory of greenhouse gas emissions, agricultural models estimate that climate change will directly reduce food production from maize, soybeans, wheat and rice by as much as 43 percent by the end of the 21st century. But hydrological models looking at the effect of warming climate on freshwater supplies project further agricultural losses, due to the reversion of 20 to 60 million hectares of currently irrigated fields back to rain-fed crops.”

The study’s lead author, Joshua Elliot, said the analysis is the first of its kind to feature an in-depth comparison of agricultural and hydrological models, which resulted in dramatically different results from other research.

“It’s a huge effect, and an effect that’s basically on the same order of magnitude as the direct effect of climate change,” Elliott, a research scientist with the Computation Institute’s Center for Robust Decision Making on Climate and Energy Policy (RDCEP), Argonne National Laboratory, is quoted as saying. “So the effect of limited irrigation availability in some regions could end up doubling the effect of climate change.”

The “good” news, if any, is that some areas will most likely see more precipitation, which could mitigate some of the effects of shortages, the study says.

The study, entitled “Constraints and potentials of future irrigation water availability on agricultural production under climate change” and conducted under the auspices of the Agricultural Model Intercomparison and Improvement Project, as part of the Inter-Sectoral Impacts Model Intercomparison Project, was published in Proceedings of the National Academy of Sciences.
