NASA Study and Long-Term Warming

Yet another new study from NASA finds the the climate’s sensitivity to carbon pollution is on the high side. That means, in the absence of rapid reductions in greenhouse gases, global warming is likely to be high enough to destroy a livable climate.[read more]

Faux Pause 2: Warmest November On Record As New Studies Confirm Warming Trend

Temperature Records

Last month saw the hottest global November surface temperature on record, according to the latest data from NASA. Of course, the global surface temperature is only one of the many indicators the planet actually just keeps warming.[read more]

NASA Projects Global Rainfall Patterns Due to Climate Change

May 6, 2013 by Joseph Romm

In response to carbon dioxide-induced warming, the global water cycle undergoes a gigantic competition for moisture resulting in a global pattern of increased heavy rain, decreased moderate rain, and prolonged droughts.[read more]

A New Era in Space

July 8, 2011 by Geoffrey Styles

In the lead-up to the launch of the last space shuttle, "Atlantis", I've been seeing a number of articles on the general theme of an era ending. This week's Economist went so far as to suggest it marks the "End of the Space Age." I sincerely hope they are wrong, and not just because I have followed the US space program avidly since...[read more]

NASA’s James Hansen Says Nuclear Is Safer Than Fossil

June 24, 2011 by Jonathan Smith

Image via Wikipedia In a Treehugger interview on Climate Change and Intergenerational Justice, NASA’s James Hansen says it is very unfortunate that “a number of nations have indicated that they’re going to phase out nuclear power… The truth is, what we should do is use the more advanced nuclear power. Even the old nuclear power is much...[read more]

NASA Map Shows How Much Carbon Is Stored By Global Forests; Emphasizes Need to Halt Deforestation

June 1, 2011 by Jake Schmidt

NASA has just released a new map which shows the carbon stored in the forests around the world.  While it doesn’t show us exactly which forests are at risk of deforestation – thus turning the current stored carbon into carbon pollution that causes global warming – it does provide us with a visual of what is at risk if we don’t...[read more]

energyNOW! Video: The Future of Flight

April 25, 2011 by Silvio Marcacci

Engineers are constantly trying to make airplanes more efficient, and there's finally a big push to do so. In “The Future of Flight,” Special Correspondent Josh Zepps takes a look at how the aviation industry is evolving to meet new needs and pressures, with new aircraft designs and advanced fuels.[read more]

The Science Behind Obama's Legislative “Chunks”

January 5, 2011 by David Livingston

Given President Obama’s recent declaration that the new course of energy policy may come in the form of “chunks” rather than comprehensive legislation, we must ask ourselves which chunks to push for first if we want better emission outcomes? In order to answer this question, it is necessary to better understand the emissions profile of...[read more]

NASA explains how Europe can be so cold amidst the hottest November and hottest year on record

December 12, 2010 by Joseph Romm

How did we get record-breaking November warmth in the middle of a strong La Niña that would normally cool global temperatures (as it did in the fall of 1998, see lower right figure, blue line)?  Is the answer the Arctic sea ice death spiral 2010?  And is the loss of Arctic sea ice also responsible for the frigid European...[read more]

NASA: Does heating from black carbon increase cooling from clouds?

September 17, 2010 by Joseph Romm

Black carbon particles, commonly called soot, are dark and light-absorbing and therefore warm the climate. Soot comes from combustion of fossil and biofuels, especially burning of diesel, coal and wood. Due to its warming effects, reduction of soot could help cool climate. However, soot absorption also affects cloud distributions...[read more]

NASA reports hottest January to August on record - August tied for hottest in UAH satellite record*

September 12, 2010 by Joseph Romm

Last month, NASA reported it was the hottest January-July on record, along with a terrific analysis, “July 2010 — What Global Warming Looks Like,” which noted that 2010 is “likely” to be warmest year on record. This month continues the trend of 2010 outpacing previous years, according to NASA: It seems all but certain we will...[read more]

An important mission for NASA

April 8, 2010 by David Hone

I was very fortunate to see the launch of the space shuttle in Florida this week. More of that at the end, but you might wonder why this belongs in a climate change blog? Whilst flicking through the NASA web-site to find details of the launch and the best viewing locations, I came across two items which have an important link. The first...[read more]

Hansen calls climate change “predominant moral issue of the 21st century,” slams Congress, Cantwell-Collins

April 7, 2010 by Joseph Romm

The country’s top climatologist, NASA’s James Hansen, writes in HuffPost: The predominant moral issue of the 21st century, almost surely, will be climate change, comparable to Nazism faced by Churchill in the 20th century and slavery faced by Lincoln in the 19th century. Our fossil fuel addiction, if unabated, threatens our children...[read more]

NASA: “It is nearly certain that a new record 12-month global temperature will be set in 2010″ - Must-read draft paper: "We conclude that global temperature continued to rise rapidly in the past decade" and "that there has been no reduction in the globa

NASA’s Goddard Institute for Space Studies (GISS) has released a draft paper “Current GISS Global Surface Temperature Analysis.”  It is a must read for warming junkies, but, as James Hansen notes in an e-mail, “it is too long for popular use.”  So Hansen offers “some of the main conclusions,” as well as a description of a...[read more]

NASA images of Mertz iceberg

February 27, 2010 by Lou Grinzo

Our friends at NASA have a page on their Earth Observatory site (which should be on your list of “check every day” sites, needless to say) about the Mertz iceberg, Collision Calves Iceberg from Mertz Glacier Tongue, Antarctica : Image of the Day: At 94 kilometers (58 miles) by 39 kilometers (24 miles) in size, the B-09B iceberg is...[read more]
