In Greenland’s Melting Ice, A Warning on Hard Climate Choices…

Greenland is melting at an unprecedented rate, causing vast quantities of ice to disappear and global sea levels to rise. The fate of the ice sheet is not sealed, but unless CO2 emissions are sharply cut, the long-term existence of Greenland’s ice is in doubt… Read the article here at Yale Environment 360: https://e360.yale.edu/features/in-greenlands-melting-ice-a-warning-on-hard-climate-choices Advertisements

As Water Scarcity Increases, Desalination Plants Are on the Rise…

After decades of slow progress, desalination is increasingly being used to provide drinking water around the globe. Costs for processing salt water for drinking water have dropped, but it remains an expensive option and one that creates environmental problems that must be addressed… Read about this rise in desalination processes here at Yale Environment 360: […]

How an Illicit Chemical Is Jeopardizing Recovery of the Ozone Layer…

An international treaty signed in 1987 officially halted production and use of chemicals that deplete the atmosphere’s critical ozone layer. But new research finds a troubling rise in emissions of a banned chemical that is being routinely used in factories in northeast China… Read this article here, at Yale Environment 360: https://e360.yale.edu/features/how-an-illicit-chemical-is-jeopardizing-recovery-of-the-ozone-layer-china

Oceans are warming even faster than previously thought…

Summary:. Heat trapped by greenhouse gases is raising ocean temperatures faster than previously thought, concludes an analysis of four recent ocean heating observations. The results provide further evidence that earlier claims of a slowdown or ‘hiatus’ in global warming over the past 15 years were unfounded… Read the article here at Science Daily: https://www.sciencedaily.com/releases/2019/01/190110141811.htm

‘Abrupt thaw’ of permafrost beneath lakes could significantly affect climate change models…

Summary:  Methane released by thawing permafrost from some Arctic lakes could significantly accelerate climate change, according to a new study. Unlike shallow, gradual thawing of terrestrial permafrost, the abrupt thaw beneath thermokarst lakes is irreversible this century. Even climate models that project only moderate warming this century will have to factor in their emissions, according […]

Blocking sunlight to cool Earth won’t reduce crop damage from global warming…

Summary:  Proposals to inject sulfate aerosols into the upper atmosphere to block and scatter sunlight and reduce global temperatures could, some say, also increase crop yields because of reduced heat stress on plants. A new study shows that other effects counterbalance the positive effects of reduced heat stress. Specifically, blocking sunlight reduces photosynthesis, which offsets […]

Taking the Long View: The ‘Forever Legacy’ of Climate Change…

Intro (Yale Environment 360): Climate change projections often focus on 2100. But the geological record shows that unless we rapidly reduce greenhouse gas emissions, we will be locking in drastic increases in temperatures and sea levels that will alter the earth not just for centuries, but for millennia… Read the article at Yale Environment 360:  http://e360.yale.edu/features/taking-the-long-view-the-forever-legacy-of-climate-change

Icy air reveals human-made methane levels higher than previously believed…

An article from enn.com: Intro: In 2011 a team of researchers led by Vasilii Petrenko, an assistant professor of Earth and environmental sciences at the University of Rochester, spent seven weeks in Antarctica collecting and studying 2,000-pound samples of glacial ice cores that date back nearly 12,000 years. The ancient air trapped within the ice revealed surprising new […]

Turning the climate tide by 2020… 

Summary (ScienceDaily):  The world needs high-speed climate action for an immediate bending — down of the global greenhouse — gas emissions curve, leading experts caution. Aggressive reduction of fossil-fuel usage is the key to averting devastating heat extremes and unmanageable sea level rise, authors argue. In the run-up to the G20 summit of the planet’s […]
