First launched in January 2014, the initial course was followed by more than 14,000 students from around the world. (PRWEB) April 07, 2014 Scientists from Scripps Institution of Oceanography at UC San Diego have again collaborated with UC San Diego Extension to offer a repeat session of their popular massive open online course (MOOC) on global climate change. The 10-week course, “Climate Change in Four Dimensions: Scientific, Policy, International, and Social,” begins April 8. First...

LA JOLLA, Calif., Nov. 26, 2013 /PRNewswire/ -- Four renowned scientists from the University of California San Diego and Scripps Institution of Oceanography are offering a free online climate change course starting in January 2014. "Climate Change in Four Dimensions: Scientific, Policy, International and Social" is one of the first massive open online courses (MOOC) being offered as a non-credit course by UC San Diego. The course is being taught by professors Charles Kennel, Naomi...

A recent increase in the intensity of Arabian Sea cyclones may be the result of increasing air pollution over the Indian sub-continent, according to a new multi-institutional study. Traditionally, prevailing wind shear patterns prohibit cyclones in the Arabian Sea from becoming major storms.  However, the study suggests that weakening winds have enabled the formation of stronger cyclones in recent years -- including storms in 2007 and 2010 that were the first recorded storms to enter...

The magnitude of climate change during Earth's deep past suggests that future temperatures may eventually rise far more than projected if society continues its pace of emitting greenhouse gases, a new analysis concludes. The study, by National Center for Atmospheric Research (NCAR) scientist Jeffrey Kiehl, will appear as a "Perspectives" piece in this week's issue of the journal Science. Building on recent research, the study examines the relationship between global temperatures and high...

Soot from the burning of fossil fuels and solid biofuels contributes far more to global warming than has been thought, according to a new Stanford study.  But, unlike carbon dioxide, soot lingers only a few weeks in the atmosphere, so cutting emissions could have a significant and rapid impact on the climate. Controlling it may be the only option for saving the Arctic sea ice from melting. If soot emissions were eliminated, more than 1.5 million premature deaths from soot inhalation...

Fulfilling Copenhagen Accord will require variety of efforts ranging from 'Herculean' to the readily actionable, scientists say Major greenhouse gas-emitting countries agreed in December climate talks held in Copenhagen that substantial action is required to limit the increase of global average temperature to less than 2 degrees C (3.6 degrees F). In a paper appearing May 3 in the Proceedings of the National Academy of Sciences (PNAS), Veerabhadran Ramanathan and Yangyang Xu, climate...

WASHINGTON, Oct. 12 /PRNewswire-USNewswire/ -- Reducing non-CO2 climate change agents such as black carbon soot, tropospheric ozone, and hydrofluorocarbons (HFCs), as well as expanding bio-sequestration through biochar production, can forestall fast approaching abrupt climate changes, according to Nobel Laureate Dr. Mario Molina and co-authors in a paper published today in the Proceedings of the National Academy of Sciences (PNAS).

Swedish and Indian researchers constrain the sources of climate- and health-afflicting soot pollution over South Asia A gigantic brownish haze from various burning and combustion processes is blanketing India and surrounding land and oceans during the winter season. This soot-laden Brown Cloud is affecting South Asian climate as much or more than carbon dioxide and cause premature deaths of 100 000s annually, yet its sources have been poorly understood. In this week's issue of Science...

Thick smog clouds that loom over Asia threaten the livelihood of crops and contain particles that actually reflect the sun's rays away from the earth, the U.N. reported on Thursday. These so-called "atmospheric brown clouds" are primarily caused by the burning of fossil fuels and firewood. They can be more than one mile thick and result in changing weather patterns in areas across Asia, the Middle East, southern Africa and the Amazon Basin. First identified by the report's lead researcher in...
