Arctic melt season lengthening, ocean rapidly warming

This item was filled under Climate
The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap's thickness, according to a new study....

Changes in Climate Could Make Pesticides More Toxic to Estuarine Organisms

This item was filled under News
Changes in climate may influence pesticide toxicity in the coastal zone, according to a recent study by NOAA's National Centers for Coastal Ocean Science (NCCOS). Pesticides enter our estuarine waters by runoff from land following a storm. These pesticides are used for agricultural, turf grass, home and garden, and mosquito control applications.

Temperature fluctuations: Atlantic Ocean dances with the sun and volcanoes

This item was filled under Climate
Natural fluctuations in the ocean temperature in the North Atlantic have a significant impact on the climate in the northern hemisphere. These fluctuations are the result of a complex dance between the forces of nature, but researchers can now show that solar activity and the impact of volcanic eruptions have led this dance during the last two centuries....

Seasonal Arctic summer ice extent still hard to forecast, study says

This item was filled under Climate
Scientists analyzed 300 summer Arctic sea ice forecasts from 2008 to 2013 and found that forecasts are quite accurate when sea ice conditions are close to the downward trend that has been observed in Arctic sea ice for the last 30 years. However, forecasts are not so accurate when sea ice conditions are unusually higher or lower compared to this trend....

Core skin bacterial community in humpback whales

This item was filled under Climate
Bacteria are invisible to the naked eye, but they reside on nearly every surface humans encounter -- including the skin. Uncovering the role these microorganisms play in human health is a major focus of research in skin microbiology, but little is known about the identity or function of skin bacteria in other mammals. Researchers have now identified a core skin bacterial community that humpback whales share across populations, which could point to a way to assess the overall health of these endangered marine mammals....

Cuvier’s beaked whales set new breath-hold diving records: Whales dive to nearly two miles depth, for over two hours

This item was filled under Climate
Scientists monitored Cuvier's beaked whales' record-breaking dives to depths of nearly two miles below the ocean surface and some dives lasted for over two hours....

Major increase in West Antarctic glacial loss

This item was filled under Climate
Six massive glaciers in West Antarctica are moving faster than they did 40 years ago, causing more ice to discharge into the ocean and global sea level to rise, according to new research....

Causes and consequences of global climate warming 56 million years ago

Scientists have ruled out the hypothesis that the fall in sea level was responsible for unleashing global warming 56 million years ago. he growing and justified concern about the current global warming process has kindled the interest of the scientific community in geological records as an archive of crucial information to understand the physical and ecological effects of ancient climate changes....
