The White House and the U.S. Environmental Protection Agency (EPA) released a new peer-reviewed report saying inaction on climate change is a dire threat to human health and the economy. It specifically estimates the physical monetary paybacks across 20 sectors of the United States by year 2100 if world leaders successfully limit global warming to 2 degrees Celsius above pre-industrial levels. Among its findings: agricultural losses could be reduced by as much as $11 billion, there could be as many as 57,000 fewer deaths from poor air quality and as much as $110 billion in lost labor hours could be avoided. If nothing is done by 2100, the United States will see thousands of additional deaths annually related to extreme temperatures and poor air quality.
"The results are quite startling and very clear," said Environmental Protection Agency administrator Gina McCarthy. "Left unchecked, climate change affects our health, infrastructure and the outdoors we love. But more importantly the report shows that global action on climate change will save lives."
The Washington Post notes one major concern with the study, citing a recent International Energy Agency analysis: Though several major new international commitments could move the world in the right direction, the planet is almost certainly not going to hit its 2 degree target.
The report follows the release of Pope Francis' encyclical--acknowledging that climate change is largely caused by humans--sparking bipartisan reaction. A review of surveys by the Yale Project on Climate Change Communication and George Mason University found the majority of Catholic Republicans agreed that global warming is happening.
EPA Clean Power Plan Under Fire
A White House official this week said the final version of the EPA's Clean Power Plan would retain its ambitious 30-percent cut in emissions. Slated to be finalized in August, the rule would limit emissions from existing power plants under the Clean Air Act by giving states flexibility in how they can meet interim state-level emissions rate goals (2020 to 2030) and a final 2030 emissions rate limit.
Bills to scale back its intended benefits were the subject of House hearings this week. One in particular, the Ratepayer Protection Act--which Obama threatened to veto--was passed with a 247-180 vote by House Republicans Wednesday. It would pause implementation of the rule until all legal challenges have been settled. It also would allow states to opt out if the rule leads to rate increases. Manufacturers on Wednesday urged lawmakers to pass the bill. A letter from the National Association of Manufacturers noted that the "rule has the potential to substantially increase the costs of electricity for manufacturers and could threaten the reliability of the electric grid in many parts of the country." But a report from Public Citizen suggests the Clean Power Plan will actually be beneficial to consumers and the economy generally.
2015 on Pace to Be Warmest Year on Record
The National Oceanic and Atmospheric Administration's (NOAA) National Climatic Data Center, the National Aeronautics and Space Administration's (NASA) Goddard Institute for Space Studies, and the Japanese Meteorological Agency last week reported that the first five months of this year are the hottest since record keeping began in 1880, putting 2015 on track to top 2014 as the warmest year on record.
In May, the combined land and ocean surface temperature was 1.57 degrees Fahrenheit above the 20th-century average, 0.14 degrees above the previous record set in May 2014.
According to NOAA, record warm sea-surface temperatures in the northeast and equatorial Pacific Ocean as well as areas of the western North Atlantic Ocean and Barents Sea north of Scandinavia contributed to the anomalous heat so far in 2015.
"The oceans have been what's really been driving the warmth that we've seen in the last year and a half to two years," said Deke Arndt, head of climate monitoring at NOAA's National Centers for Environmental Education. "We've seen really large warmth in all of the major ocean basins. So, if there's anything unusual or weird, I guess, about what we're seeing, it's the fact that the entire global ocean is participating in this really extreme warmth that we've seen in the last couple years."
The current El Niño event could help keep temperatures at record or near-record levels for the remainder of the year, but climate scientists are cautious about saying whether 2015 will definitely be a record breaker for heat.
"We expect that we are going to get more warm years, and just as with 2014, records will be broken increasingly in the future. But perhaps not every year," said Gavin Schmidt, who leads NASA's Goddard Institute of Space Studies.
