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…)

Earth’s Lakes Warming Due to Climate Change

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…)

Global Model Confirms: Cool Roofs Can Offset Carbon Dioxide Emissions and Mitigate Global Warming

Can light-colored rooftops and roads really curb carbon emissions and combat global climate change?  

The idea has been around for years, but now, a new study by researchers at Lawrence Berkeley National Laboratory that is the first to use a global model to study the question has found that implementing cool roofs and cool pavements in cities around the world can not only help cities stay cooler, they can also cool the world, with the potential of canceling the heating effect of up to two years of worldwide carbon dioxide emissions.
