According to a new NASA study, a class of widely used chemical coolants known as hydrofluorocarbons (HFC), found in refrigerators and in home and automobile air conditioners, contributes to ozone depletion by a small but measurable amount, countering a decades-old assumption. A class of widely used chemical coolants known as hydrofluorocarbons (HFC) contributes to ozone…

Arctic Sea Ice Summertime Minimum Is Fourth Lowest on RecordAccording to a NASA analysis of satellite data, the 2015 Arctic sea ice minimum extent is the fourth lowest on record since observations from space began. The analysis by NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado at…
Members of NASA’s new interdisciplinary Sea Level Change Team discussed recent findings and new agency research efforts during a media teleconference Aug. 26, 2015, at 12:30 p.m. EDT. The panelists for this briefing were: — Michael Freilich, director of NASA’s Earth Science Division at the agency’s headquarters in Washington— Steve Nerem, lead for NASA’s Sea…
We all have a responsibility to become better citizens of the world. Whether that involves making purchases that are more ethical, attempting to travel sustainably or taking the leap from vegetarian to vegan, it’s our duty to give Mother Nature a helping hand against climate change, environmental degradation and resource depletion. Indeed, with almost two…
Seas around the world have risen an average of nearly 3 inches since 1992, with some locations rising more than 9 inches due to natural variation, according to the latest satellite measurements from NASA and its partners. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of…
Aug. 28, 2015: More than 90 percent of our planet’s freshwater ice is bound in the massive ice sheets and glaciers of the Antarctic and Greenland. As temperatures around the world slowly climb, melt waters from these vast stores of ice add to rising sea levels. All by itself, Greenland could bump sea levels by…
This is the second of a series of rap lectures about climate change. The focus here is on the consequences of global warming. LYRICSThe CO2 we’ve dumped into the atmosphere won’t disappearIt’s gonna last a hundred years while trappin’ heat up in the airThe reason temperature’s up less than one degreeIs the climate’s inertia…
We need to reduce emissions to keep our planet safe for future generations – the science is clear. However, it can be quite hard to get your head around how to do that. Here’s a very simple idea from writer and climate campaigner, Bill McKibben: keep fossil fuels in the ground. If we were to burn…
