Widespread support for climate action in 4 major European countries
The average global temperature spiked to yet another record in March 2016.
More than eight out of 10 people in the UK, France, Germany and Norway believe that the world’s climate is changing, and a similar proportion think that it is at least partly caused by human activity, according to a recent scientific survey conducted by European researchers.
EPA administrator Scott Pruitt may have to back up his false claims on greenhouse gases and climate change in court. A lawsuit filed April 13 by the watchdog group Public Employees for Environmental Responsibility wants the agency head to show studies backing up his statements that call into question the role of CO2 emissions in global warming. The lawsuit also seeks to determine whether EPA possesses a single study that supports Mr. Pruitt’s stance. Continue reading “EPA chief sued for ‘spouting deceptive climate pseudo-science’”→
If you’re a long-time Summit Voice follower you’ve noticed that the pace of posts has dropped off a bit in the past few months, but that’s only because some of the content has moved to other locations. So here’s a quick roundup of some of my latest environment and climate stories from around the world.
For InsideClimate News, I took a close look at some of the latest research on ocean heat content, featuring work by Kevin Trenberth, with the National Center for Atmospheric Research in Boulder. The new study he co-authored took a close look at data from thousands of autonomous ocean probes that measure ocean temperatures from the surface all the way down to a depth of 2,000 meters. The study found that the rate of ocean warming has doubled since the early 1990s from previous decades, and that the heat is getting into deep waters. The study also tracks regional variations in ocean warming, important because it will affect where and when sea level rises fastest: Rate of Ocean Warming Has Nearly Doubled Over 25 Years.
I also did some in-depth reporting on a potentially groundbreaking legal case in Austria, where an administrative law court ruled that citizens have a legal right to be protected from climate change impacts when the blocked construction of a third runway at the Vienna International Airport: Vienna Airport Expansion Blocked on Climate Change Grounds.
In my first story for Deutsche Welle, which is a German equivalent of NPR and PBS, I reported on how global warming is increasing forest fire danger all over the world, including forests in temperate, wet climates like Central Europe, even in the Alps. While residents of the West already have seen fire activity surge in the past 20 years, some other regions are just starting to experience those changes, and the risks are great: Global warming is increasing forest fire risk in the Alps.
Globally, there are also burgeoning efforts to electrify the transportation system in the fight to limit greenhouse gas emissions and avert dangerous climate change. In Austria, the federal government has teamed up with the private sector to invest in e-mobility. Consumers can get rebates of up to €4,000 for buying electric cars, and even E-bikes, and there are also subsidies available for investments in expanding the electric charging infrastructure. Altogether, the government expects that their initial €72 million investment will help spur the creation of 30,000 new jobs and €3 billion in new economic activity: Austria Is Making Electric Cars More Affordable Than Ever.
Volcanoes seen as likely trigger for global glaciation
A 10-year string of steady volcanic eruptions may have been the trigger for a massive global cooling event that left much of the Earth encased in glaciers and ice sheets about 771 million years ago.
The eruptions could have spewed so much sulphur dioxide into the atmosphere that the planet’s climate reached a tipping point, resulting in what scientists call ‘snowball Earth,” according to a new study published this month in Geophysical Research Letters. Understanding the natural variability of climate is important to understanding current climate change driven by emission of greenhouse gases. Continue reading “What caused ‘snowball Earth?’”→
Nearly a quarter of the U.S. was record warm in February, and nationwide, it ended up as the second-warmest February on record, just behind 1954. The winter (December to February) was the sixth-warmest, according to the latest State of the Climate update from the National Centers for Environmental Information.
By the numbers, the average temperature across the lower 48 states for Februrary was 41.2 degrees Fahrenheit, which is 7.3 degrees Fahrenheit above the 20th century average. The winter as a whole (December to February) was 3.7 degrees Fahrenheit above average.
The only state reporting widespread below-average temperatures was Washington, with slightly below to near average readings in Oregon, Northern California, northern Idaho and Montana.
By contrast, 16 states, stretching from Texas up the Mississippi Valley to the Midwest, New York and the central Atlantic Coast, were record warm. Three states, including Colorado, reported their all-time warmest minimum average temperatures, in line with global warming trends showing nighttimes heating faster than days.
According to the report, there were 11,743 daily warm temperature records broken or tied, compared to 418 daily cold records. Of those, 1,151 daily records also broke the warmest temperature record ever observed during February, compared to just 2 cold records.
The U.S. February temperatures are in line with the rest of world, according to the EU’s Copernicus Climate Change Service, which reported earlier this week that the average global temperature for February was the second-warmest on record.
So far, there’s little sign of a post El Niño drop in global temperatures, according to the European Copernicus Climate Change Service, which has new data showing that last month was the second-warmest February on record for Earth. According to the report, February 2017 “extended the spell of exceptional global warmth that has now lasted since mid-2015.”
The loss of Arctic sea ice may not lead directly to an increase in cold weather extremes in Europe, according to scientists who studied the links between Arctic changes and mid-latitude weather. In the study, scientists with the University of Exeter found that dwindling sea ice does affect the North Atlantic Oscillation (NAO) weather phenomenon, which affects winter weather conditions in Northern Europe, in places such as the UK, Scandinavia and the Baltic states.
