Study finds climate change beliefs in the U.S. linked with personal weather experiences
Meteorologists, climate scientists and journalists have apparently failed to convey the message that global climate change and local day-to-day weather conditions are two separate things. A study published this week suggests that Americans’ beliefs about global warming are based on how often they personally experience weather-related events.
One of the paper’s co-authors explained the findings in a press release.
“One of the greatest challenges to communicating scientific findings about climate change is the cognitive disconnect between local and global events,” said Michael Mann, associate professor of geography at George Washington University. “It is easy to assume that what you experience at home must be happening elsewhere.” Continue reading “Still so much confusion about weather versus climate”→
November’s average global temperature was 1.31 degrees Fahrenheit above the 20th century average, making it the fifth-warmest November on record. According to the latest global state of the climate report from the National Centers for Environmental Information, it was cooler than last year’s record by 0.41 degrees Fahrenheit, but 0.09 degrees warmer than the average for the 21st century.
According to the report, warmer-than-average conditions prevailed across most of the globe’s land areas, with record warmth in parts of central and southeastern Canada, where temperatures were at least 9 degrees Fahrenheit above the 1981–2010 average in many places. Other warm regions included the far northern tier of the United States along with a portion of the southwest, parts of western and southern Mexico, sections of eastern and west central Africa, and regions of some southeastern Asia island nations.

New measurements taken in the ocean near a massive East Antarctica ice sheet confirm that warm water is melting the ice from below. The new data will help scientists determine how fast the Totten Ice Shelf will melt. In all, it contains enough water to raise global sea level by 3.5 meters, according to a new study published last week in Science Advances.
And according to the watchdog group Citizens Against LNG, the Jordan Cove Energy Project, L.P. also formally requested that its application for a Site Certificate for their South Dunes Power Plant be withdrawn from further consideration by the Oregon Energy Facility Siting Council and the Oregon Department of Energy. Without that power plant, there won’t any terminal at Coos Bay, activists say.
The idea, according to WSCOGA, is to develop Western Colorado’s vast Mancos Shale gas potential — an energy reserve among the largest natural gas resources in North America. According to the press release, natural gas producers in the Piceance Basin “have applauded Jordan Cove LNG’s decisive and speedy decision to pursue reapplication and approval of the most important energy infrastructure project in the Western United States.” Continue reading “Opinion: Colorado, you are so fracked …”→
Record and near-record readings from coast to coast
November 2016’s average temperature across the U.S. was 6.3 degrees Fahrenheit above the 20th century average, making it the second-warmest on record, behind 1999. According to the latest monthly update from the National Centers for Environmental Information, November is warming at a rate of 6.6 degrees Fahrenheit per century. Only January has been warming faster, at a rate of 10.5 degrees Fahrenheit per century.
Remarkable changes with huge planetary implications
Earth’s climate control system — the Arctic — is changing so fast that researchers are having a hard time keeping up. In an effort to understand how the region is shifting toward a new state, a team of scientists spent nearly six months examining the younger and thinner sea ice that’s become ubiquitous in the past few years. They discussed their findings this week at the fall meeting of the American Geophysical Union in San Francisco.
“Many things we experienced took us by surprise,” said Mats Granskog, a research scientist at the Norwegian Polar Institute and chief scientist of the Norwegian young sea ICE, or N-ICE2015 project. “We saw that the new Arctic, with much thinner sea ice only three to four feet thick, functions much differently from the Arctic we knew only 20 years ago, when the ice was much thicker.”
One of the biggest concerns is that the reduced sea-ice coverage and thickness will lead to even more melting, the so-called Arctic amplification. Most of the solar energy that reaches Arctic snow and sea ice gets reflected back into space. But when the snow and ice is replaced by darker, open water, most of the energy gets absorbed and in turn helps melt more ice. Continue reading “Climate scientists track young, thin Arctic ice”→
U.S. Geological Survey scientists have completed one of the first experimental studies to explore links between climate change and invasive species, specifically how brook trout and brown trout interact with rising stream temperatures. They found that non-native browns limit the ability of brook trout to use warmer water temperatures, By contrast, removin of browns brook trouts’ reach into warmer waters.
