The latest EPA data show that in 2016, transportation in California, Texas and Florida was the source of more carbon dioxide pollution than transportation in rest of the United States. California, Texas and Louisiana led country in emissions from industry. Wyoming had the most emissions on a per capita basis. (Double click to enlarge the chart. Source: Politico)
By William S. Becker If Majority Leader Mitch McConnell brings the Green New Deal to a vote in the Senate this week as he intends, the result will be political theater. It won’t be more than that. Why? Because in its present form, the Green New Deal is a vision articulated in a nonbinding resolution, and the opposition of the Republican-controlled Senate is preordained. Here is what we’re likely to witness: McConnell and his Republican colleagues will try to brand the entire Democratic Party as a big-government socialist cabal. Democrats, who actually represent 50 shades of opinion on the proposals in the Green New Deal, may ask why so many Republicans are still ignoring climate change when half the states with the most weather disasters are “red”. If Senate Democrats have done their homework, they might ask McConnell how denying climate change is good for his constituents in Kentucky. The state ranks 12th the nation for its number of natural disasters. It has averaged more than one disaster declaration a year for the last 66 years. Yet it ranks 48th
The Green New Deal proposal in Congress has caused a great deal of buzz, some of it enthusiastic, some of it skeptical and some of it negative. But we should be asking this: If not the Green New Deal, or something like it, then what are our options? There should be no debate about the fact that the United States and the rest of the world must act boldly and quickly to pull back from far more disastrous impacts of climate change than we are experiencing today. This post offers a set of slides that show some of the good news and the bad news about our response to climate change so far. Many of the illustrations come from Statista, a service that analyzes data from more than 22,500 sources to spot trends on a wide variety of topics including energy and climate. Others come from the Yale Program on Climate Change Communications, PoliticoPro and other data organizations. What we see is this: Although climate change must be addressed by every nation, the United States is in the driver's seat
Editor's Note: In this blog, Dr. Charles Kutscher, a member of PCAP's National Advisory Committee, rebuts the argument that 100% renewable energy is not practical. Dr. Kutscher is a Fellow and Senior Research Associate of the Renewable and Sustainable Energy Institute, a joint institute between the University of Colorado-Boulder and the National Renewable Energy Laboratory (NREL). He served as the Director of the Buildings and Thermal Sciences Center at NREL from 2013 until his retirement in 2018. By Charles F. Kutscher Wind and solar energy are now very low in cost and have comprised more than half of new U.S. electric capacity additions for four of the last five years. Not surprisingly, they have become a target for those who want to continue our reliance on conventional energy sources. A case in point is a recent article, What It Costs To Go 100 Percent Renewable, by Philip Rossetti of the American Action Forum, which opposes the Green New Deal and argues that 100% renewable energy is impractical. I see several issues with Mr. Rossetti’s analysis, and to address them we
James Hansen et.al. in Atmospheric Chemistry and Physics. Modeling, paleoclimate evidence, and ongoing observations together imply that 2oC global warming above pre industrial level could produce several several changes in ocean overturning circulation, increasingly powerful storms, the potential for cooling in Europe and nonlinear sea-level rise.

Clark, Harvard University, Cambridge, MA, and approved July 6, 2018 (received for review June 19, 2018) Abstract We explore the risk that self-reinforcing feedbacks could push the Earth System toward a planetary threshold that, if crossed, could prevent stabilization of the climate at intermediate temperature rises and cause continued warming on a “Hothouse Earth” pathway even as human emissions are reduced. Crossing the threshold would lead to a much higher global average temperature than any interglacial in the past 1.2 million years and to sea levels significantly higher than at any time in the Holocene. We examine the evidence that such a threshold might exist and where it might be. If the threshold is crossed, the
Self-reinforcing feedbacks could push the Earth past the threshold of climate stabilization and into an ongoing path to a "Hothouse Earth", even if emissions were reduced. That is the conclusion of an international group of 16 scientists published Aug. 6, 2018, in the Proceedings of the National Academy of Science. "Crossing the threshold would lead to a much higher global average temperature than any interglacial in the past 1.2 million years and to sea levels significantly higher than at any time in the Holocene," the authors report. "We examine the evidence that such a threshold might exist and where it might be. "If the threshold is crossed, the resulting trajectory would likely cause serious disruptions to ecosystems, society, and economies. Collective human action is required to steer the Earth System away from a potential threshold and stabilize it in a habitable interglacial-like state. Such action entails stewardship of the entire Earth System—biosphere, climate, and societies—and could include decarbonization of the global economy, enhancement of biosphere carbon sinks, behavioral changes, technological innovations, new governance arrangements, and transformed social values."

In order to keep global warming below 2oC, two-thirds of the world's proved fossil energy reserves will have to remain unburned. Nevertheless, oil, gas and coal companies are continuing to invest in exploration and are underestimating the risk of large stranded investments. In this seminal study, Carbon Tracker describes the "carbon bubble" and what it means for shareholders in fossil energy companies. Read more
Climate change is a significant threat to the health of the American people. The impacts of human-induced climate change are increasing nationwide. The overall findings of this study, conducted by a consortium of federal agencies, underscore the significance of the growing risk climate change poses to human health in the United States.

This report provides initial findings from the national survey of American Meteorological Society (AMS) member views on climate change conducted by George Mason University and AMS, with National Science Foundation funding. Our survey was administered via email between January 6 and January 31, 2016. After making an initial request to participate, we sent up to five additional requests/reminders to participate to those people who had not yet completed a survey. A total of 4,092 AMS members participated, with participants coming from the United States and internationally. The participation rate in the survey was 53.3%. We wish to sincerely thank all AMS members who took time out of their busy schedules to participate in this research. We hope the following report is useful to them.
Ice melt, sea level rise and superstorms: evidence from paleoclimate data, climate modeling, and modern observations that 2 ◦C global warming could be dangerous
In 1988, James Hansen because the first climate scientists to warn Congress about global warming. Now he has issued a new study in which he concludes that climate change is more severe than we think. Read full article here: Ice melt, sea level rise and superstorms
