Survey shows very little climate skepticism in Europe

Widespread support for climate action in 4 major European countries

Staff Report

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.

The survey of more than 4,000 members of the public explored opinions on climate change, climate policy and future energy options. It showed that a wide majority also  support a range of different measures to combat climate change. Continue reading “Survey shows very little climate skepticism in Europe”

EPA chief sued for ‘spouting deceptive climate pseudo-science’

EPA staff concerned about possible data purge

The EPA website clearly discloses how greenhouse gases affect the climate.

Staff Report

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’”

Atlantic Ocean warmth melts sea ice from below

Mixing waters may hasten arrival of ice-free Arctic Ocean summers

Staff Report

In yet another sign that the balance of Earth’s climate system is being perturbed by global warming, scientists are documenting how a steady intrusion of water from the Atlantic is undermining sea ice in the Arctic Ocean.

The research, led by Igor Polyakov, a professor at the University of Alaska Fairbanks International Arctic Research Center, shows that the relatively warm  Atlantic Ocean water is a surprisingly powerful contributor to Arctic sea ice decline.

Billion dollar weather disasters piling up in early 2017

Freezes, fires and tornadoes caused significant regional economic harm in Jan.-March

Temperatures were well above average across two-thirds of the U.S. in March.

Tornadoes, wildfires, and blizzards during the second-warmest winter on record for the U.S. killed 37 people and caused an estimated $5.8 billion dollars in damage, according to the latest monthly update from federal climate trackers at the National Oceanic and Atmospheric Administration.

It was the first time there were five billion-dollar extreme weather events during the January to March period, the National Centers for Environmental Information said in the state of the climate report released Thursday. The March 6-8 tornado outbreak in the Midwest was the costliest, at $1.5 billion. The damage from California rainstorms Feb. 8-22 amounted to $1 billion, the report says.

Global warming speeds diversity threats to native fish

Study looks at hybridization of trout in Northern Rocky Mountains

Staff Report

Global warming is intensifying the hybridization of native and non-native trout in the northern Rocky Mountains, according to a new study from the U.S. Geological Survey and other scientists. The trend is a serious threat to the biodiversity of Rocky Mountain aquatic ecosystems, says the study published in the journal Global Change Biology.

As non-native rainbow trout, introduced by early settlers, interbreed with cutthroat trout it leads to a decline in local adaptations that can threaten the long-term survival of species. Preserving the  genetic integrity of native species is important for  resiliency, the scientists said. Continue reading “Global warming speeds diversity threats to native fish”

March 2017 ends up as 2d-warmest on record for Earth

Staff Report

There was no let-up in the years-long global heatwave last month, as March ended up being the second-warmest ever, just 0.10 degrees Celsius behind the record warmth of March 2016. According the European Copernicus Climate Change Service, February and March 2017 showed most significant warm anomaly since April 2016, when the mega El Niño was fading away.

Global warming is bad news for coffee lovers

Study shows how coffee plants suffer even during short heatwaves

Staff report

Heatwaves are becoming more common in a world warmed by heat-trapping greenhouse gas pollution, and at some point in the not-too-distant future, that could spell bad news for your morning cup of wake-me-up.

Scientists with Oregon State University’s College of Forestry have showed that, when Coffea arabica plants were subjected to short-duration heat waves, they became unable to produce flowers and fruit. That means no coffee beans, and no coffee to drink.

C. arabica is the globe’s dominant coffee-plant species, accounting for 65 percent of the commercial production of the nearly 20 billion pounds of coffee consumed globally each year. The plants grow in 80 countries in four continents in the tropics. Continue reading “Global warming is bad news for coffee lovers”
