“#COVID-19’s long-term effects on climate change—for better or worse” As a result of the lockdowns around the world to control COVID-19, huge decreases in transportation and industrial activity resulted in a drop in daily global carbon emissions of 17 percent in April. Nonetheless, CO2 levels in the atmosphere reached their highest monthly average ever recorded…
“#Heatwaves in Paris—can we cope without air conditioning?” Temperatures at 4 a.m. after nine days of a heatwave similar to the one in 2003. Left, without air conditioning; Right, with air conditioning and adaptive measures: urban greening, thermal insulation, reflective walls and roofs and effective recommendations for moderate use of air conditioning.

“#Changes required for net zero emissions could bring immediate benefits for air quality, new report says” Credit: Pixabay/CC0 Public Domain The UK’s transition to net zero greenhouse gas emissions could reduce air pollution in nearly every sector, from agriculture and land use to energy production, according to a new report. The report from the Defra…
“#Sahara dust cloud looms over Cuba, Caribbean and Florida” A man walks near Morro Castle as a vast cloud of Sahara dust blankets Havana A massive cloud of Saharan dust darkened much of Cuba on Wednesday and began to affect air quality in Florida, sparking warnings to people with respiratory illnesses to stay home.

“#Feed additive reduces enteric methane emissions in dairy cows” Credit: CC0 Public Domain The enteric methane mitigation potential of 3-nitrooxypropanol (3-NOP) has been confirmed in previous studies. 3-NOP is highly soluble and rapidly metabolized in the rumen. Previous studies have shown a persistent methane mitigation effect when 3-NOP is administered through the total mixed ration…
