A futuristic experiment simulating warmer environmental conditions has shown that peatland vegetation responds to higher temperatures with an earlier and longer growth period. A study published in Nature revealed that turning up the heat accelerates spring greening in mature trees, shrubs and mosses and delays fall color change.

Commercial airline pilots were significantly better at performing advanced maneuvers in a flight simulator when carbon dioxide (CO2) levels on the flight deck (cockpit) were 700 parts per million (ppm) and 1500 ppm than when they were 2,500 ppm, according to new research led by Harvard T.H. School of Public Health. The study indicates that CO2 levels directly affect pilots’ flight performance.

On June 15, 1991, Mount Pinatubo in the Philippines blew its top in an eruption of staggering proportions. It sent an ash cloud 28 miles high, filling surrounding valleys with deposits 660 feet thick and destroying almost every bridge within 18 miles. Over 800 people lost their lives.

If you fill a clear glass with lake water, chances are that the water has a slight yellow or brown color. The color is caused by dissolved organic carbon – a group of carbon compounds that wash into a lake from the soils around it when it rains or when snow melts. Dissolved organic carbon concentrations are increasing in lakes around the planet, in part because of climate change, but also due to other factors like reductions in acid rain. This causes the lake water to transition from relatively clear to a darker brown color.

NASA's Aqua satellite passed over the Central Atlantic Ocean and looked at cloud top temperatures in Debby, revealing the storm had transitioned from subtropical to tropical.
