Some People’s Climate Beliefs Shift with Weather

*Study shows daily malleability on a long-term question*

Social scientists are struggling with a perplexing earth-science question: as the power of evidence showing manmade global warming is rising, why do opinion polls suggest public belief in the findings is wavering? Part of the answer may be that some people are too easily swayed by the easiest, most irrational piece of evidence at hand: their own estimation of the day’s temperature.

In three separate studies, researchers affiliated with Columbia University’s Center for Research on Environmental Decisions (CRED) surveyed about 1,200 people in the United States and Australia, and found that those who thought the current day was warmer than usual were more likely to believe in and feel concern about global warming than those who thought the day was unusually cold. A new paper describing the studies appears in the current issue of the journal Psychological Science. (more…)

Uncertain Future for Joshua Trees Projected with Climate Change

FLAGSTAFF, Ariz. — Temperature increases resulting from climate change in the Southwest will likely eliminate Joshua trees from 90 percent of their current range in 60 to 90 years, according to a new study led by U.S. Geological Survey ecologist Ken Cole.

The research team used models of future climate, an analysis of the climatic tolerances of the species in its current range, and the fossil record to project the future distribution of Joshua trees. The study concludes that the species could be restricted to the northernmost portion of its current range as early as the end of this century. Additionally, the ability of Joshua trees to migrate via seed dispersal to more suitable climates may be severely limited. (more…)

It’s all in a Name: ‘Global warming’ versus ‘Climate change’

ANN ARBOR, Mich.— Many Americans are skeptical about whether the world’s weather is changing, but apparently the degree of skepticism varies systematically depending on what that change is called.

According to a University of Michigan study published in the forthcoming issue of Public Opinion Quarterly, more people believe in “climate change” than in “global warming.” (more…)

Warming North Atlantic Water Tied to Heating Arctic, According to New Study

The temperatures of North Atlantic Ocean water flowing north into the Arctic Ocean adjacent to Greenland — the warmest water in at least 2,000 years — are likely related to the amplification of global warming in the Arctic, says a new international study involving the University of Colorado at Boulder.

Led by Robert Spielhagen of the Academy of Sciences, Humanities and Literature in Mainz, Germany, the study showed that water from the Fram Strait that runs between Greenland and Svalbard — an archipelago constituting the northernmost part of Norway — has warmed roughly 3.5 degrees Fahrenheit in the past century. The Fram Strait water temperatures today are about 2.5 degrees F warmer than during the Medieval Warm Period, which heated the North Atlantic from roughly 900 to 1300 and affected the climate in Northern Europe and northern North America.

Highwater in Saale River

Due to heavy snow melting as the temperature turns to be ‘mild’ and simultaneous rainfall, 2011’s Winter highwater is the highest since 1946 in the Saale river in Halle (Saxony-Anhalt). The flood water reached a maximum of 6.92 m on the gauge of Halle Trotha. A record of 7 m would cause a ‘disaster alarm’. (more…)

Broken Glass Yields Clues to Climate Change

*Ordinary drinking glasses and atmospheric dust particles break apart in similar patterns*

Clues to future climate may be found in the way an ordinary drinking glass shatters.

Results of a study published this week in the journal Proceedings of the National Academy of Sciences find that microscopic particles of dust can break apart in patterns that are similar to the fragment patterns of broken glass and other brittle objects. (more…)

WASHINGTON – In the first comprehensive global survey of temperature trends in major lakes, researchers have determined that Earth’s largest lakes have warmed during the past 25 years in response to climate change.

Philipp Schneider and Simon Hook of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., used satellite data to measure the surface temperatures of 167 large lakes worldwide.

They reported an average warming rate of 0.45 degrees Celsius (0.81 degrees Fahrenheit) per decade, with some lakes warming as much as 1 degree Celsius (1.8 degrees Fahrenheit) per decade. The warming trend was global, and the greatest increases were in the mid- to high-latitudes of the Northern Hemisphere. (more…)

Scientists at the Woods Hole Oceanographic Institution (WHOI) have detected a plume of hydrocarbons that is at least 22 miles long and more than 3,000 feet below the surface of the Gulf of Mexico, a residue of the BP Deepwater Horizon oil spill.
