A long distance connection: polar climate affects trade wind strength in tropics
The impact of sea surface temperature variations in the tropical Pacific on global climate has long been recognized. For instance, the episodic warming of the tropical Pacific during El Niño events causes melt of sea ice in far-reaching parts of the Southern Ocean via its effect on the global atmospheric circulation. A new study, published this week in the journal Science Advances by an international team, demonstrates that the opposite pathway exists as well. (2020-11-20)

New technique seamlessly converts ammonia to green hydrogen
Northwestern University researchers have developed a highly effective, environmentally friendly method for converting ammonia into hydrogen. The new technique is a major step forward for enabling a zero-pollution, hydrogen-fueled economy. The idea of using ammonia as a carrier for hydrogen delivery has gained traction in recent years because ammonia is much easier to liquify than hydrogen and is therefore much easier to store and transport. Northwestern's technological breakthrough overcomes several existing barriers to the production of clean hydrogen from ammonia. (2020-11-18)

Drop in pandemic CO2 emissions previews world of electric vehicles
When the SF Bay Area mandated shelter-in-place March 16, it created a natural experiment for UC Berkeley's Ron Cohen, who had established an inexpensive pollution sensor network in local neighborhoods. The sensors showed carbon dioxide emissions plummeting 25% in the subsequent six weeks, mostly because of a 48% drop in traffic. Networks like this -- soon to be emplaced in Glasgow -- can track greenhouse gases and progress toward lowering them, including the impact of electric vehicles (2020-11-09)

Decrease in fossil-fuel CO2 emissions due to COVID-19 detected by atmospheric observations
Atmospheric observations at Hateruma Island, Japan, successfully detected the decrease in fossil-fuel CO2 emissions in China associated with the COVID-19 outbreak. The weather in Hateruma island is frequently influenced by the northwest monsoon travelling over China, which carries the emission signals of air pollutants. The observed ratios of CO2 and CH4 variabilities showed a significant decrease during February-March 2020, corresponding to about a 30% decrease in China's fossil-fuel CO2 emissions, according to a chemistry-transport model simulation.
