2008: West Nile virus (WNV), a flavivirus maintained in the bird-mosquito transmission cycle, first arrived in Canada in the summer of 2001. In 2003, due to growing concern about the impact of WNV in Canada, the Canadian Paediatric Society issued a Paediatric Infectious Disease Note followed by an Update in 2004 (1,2). The present Paediatric…
Warming in Baltic Sea linked to Vibrio infection cases +++ Number of cases may rise as oceans warm, become less saline By Nina Chestney Reuters On July 22, 2012: Manmade climate change is the main driver behind the unexpected emergence of a group of bacteria in northern Europe which can cause gastroenteritis, new research by…
Feedbacks in the climate system – in which warming is linked to natural CO2 increase, driving further warming – may operate faster than previously thought. ACE CRC: Researchers use Antarctic and Greenland ice cores to examine temperature and CO2 changes during the largest natural climate change in Earth’s recent climate history: the warming out of…
Release of 14C-depleted methane to the atmosphere from abundant gas seeps concentrated along boundaries of permafrost thaw and receding glaciers in Alaska and Greenland Nature Geoscience (2012) Abstract Methane, a potent greenhouse gas, accumulates in subsurface hydrocarbon reservoirs, such as coal beds and natural gas deposits. In the Arctic, permafrost and glaciers form a ‘cryosphere…
ClimateCrocks.com: Ok, let me apologize for the sound of my questions – I’m getting a second lavalier so that won’t happen again. That plus altitude induced hoarseness. I was interviewing Richard Alley at a conference in Colorado last week. This is part of what he said. More later.
A global data set of fatalities from nonseismically triggered landslides that resulted in loss of life between A.D. 2004 and 2010 permits for the first time proper quantification of impacts and spatial distributions. Global loss of life from landslides is poorly quantified. A global data set of fatalities from non seismically triggered landslides that resulted…
Landmark Report of an Ad Hoc Study Group on Carbon Dioxide and Climate – Woods Hole, Massachusetts to the Climate Research Board, Assembly of Mathematical and Physical Sciences, National Research Council, NATIONAL ACADEMY OF SCIENCES | Washington, D.C. 1979 We have examined the principal attempts to simulate the effects of increased atmospheric CO2 on climate.…
Hurricanes, whose development tends to be inhibited by jet streams, may become more powerful and more frequent as the jet streams move away from the sub-tropical zones where hurricanes are born. Stanford, CA—The Earth’s jet streams, the high-altitude bands of fast winds that strongly influence the paths of storms and other weather systems, are shifting—possibly…
Hurricanes and Ozone June 11, 2005 Ozone levels drop when a hurricane is intensifying. Xiaolei Zou and Yonghui Wu, researchers at Florida State University found that variations of ozone levels from the surface to the upper atmosphere are closely related to the formation, intensification and movement of a hurricane. They studied ozone levels in 12 hurricanes…
A newly-discovered connection between climate change and depletion of the ozone layer over the U.S. could allow more damaging ultraviolet (UV) radiation to reach the Earth’s surface. As reported in a paper published in the July 27 issue of Science, a team of researchers led by James G. Anderson, the Philip S. Weld Professor of…
The “Arctic Paradox” was coined during recent winters when speculations arose that the dramatic changes in the Arctic may be linked to severe snowstorms and cold temperatures in mid-latitudes, particularly along the U.S. east coast and in Europe. Recent studies have illuminated these linkages. Evidence is presented for a physical mechanism connecting Arctic Amplification —…
Jennifer Francis, Rutgers University – assesses the broad topic of the Arctic Sea Ice Decline and explains seasonal impacts. Observations, especially since the 1950’s, explain how the “Arctic Amplification” leads to rapid sea ice changes during the summer month. Much more ridging in North America during the winter. And this affects weather patterns, because a…
