Antarctica is Losing Ice Quickly, Melting Away Another Climate Skeptic Myth

Two popular climate skeptic “facts” which are claimed to disprove anthropogenic global warming are:

1.  Surface ice melting on Antarctica is decreasing.

2.  Sea ice around Antarctica is increasing.

Despite what climate skeptics assert, neither of these arguments disprove global warming.  Actually, they highlight quite the contrary:  Antarctica is in fact losing mass (ice).  Even more, ice is melting and breaking away from the continent at an incredibly accelerating rate. 

This isn’t opinion, there is data to prove it.

New Study on Solar Variability Is Neither New Nor a Study

Misinterpreting a new study requires there to be a new study in the first place. Though it may seem obvious, this basic truth was evidently lost on the throngs of deniers who pounced on a story about solar variability that appeared on the news aggregator ScienceDaily—on May 12, 2008.

The piece, entitled “Solar Variability: Striking a Balance with Climate Change,” makes the point that, over the course of the Earth’s history, the sun and volcanic eruptions have typically exerted the largest influence on climate change. In recent decades, however, the sun’s influence in particular has been replaced by that of anthropogenic activity—something which Robert Cahalan, a climatologist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, says “has never happened before.”

NASA Reneges on Transparency - Still No DSCOVR Documents

It was welcome news last month when Congress committed $9 million to refurbish the long-overdue Deep Space Climate Observatory (DSCOVR). Good start. So how about some information to go with it?

Desmog blog readers will recall the long and fruitless quest to wring documents out of NASA about the bizarre story of the DSCOVR spacecraft. This $100 million instrument was fully completed eight years ago yet has been sitting in a box in Maryland ever since.

DSCOVR was designed to directly measure climate change for the first time ever by observing our warming planet from the unique vantage of the Lagrange Point - one million miles towards the Sun.

The climate denial industry has been regularly harping on the unreliability of low Earth orbit satellite data for years. Strange then, how the very experiment that could resolve such issues was mothballed – over the strenuous objections of dozens of leading researchers.

I struggled for over a year to extract any kind of internal documents from NASA using the Freedom of Information Act and got nowhere. After 11 months of stonewalling, the space agency elected to withhold an unknown number of documents due to some very bizarre rationales. I appealed later in 2007 and was also turned down.

Then Barack Obama was elected President of the United States….

Debunking Joanne Nova's 'Skeptics Handbook' part 2: Yes, Global Warming is Real and it's Still Happening

Today we’ll look at two more of the (supposedly) bullet-proof points in Joanne Nova’s “The Skeptics Handbook.”

“Professional Speaker” turned climate expert Nova rehashes two of the more common skeptic talking points, that: the world is no longer warming and the Vostok ice core record proves that rising CO2 emissions are not the cause of warmer temperatures.

As skeptics love to point out, the planet has not appreciably warmed over the last decade even though carbon dioxide levels have greatly increased. While it’s true that surface temperatures have remained essentially flat over the last 10 years, taking such a myopic view of the temperature record obscures the much more meaningful long-term trends.

Indeed, if you look at the temperature record of the last 150 years or so, you’ll find it extremely hard not to notice the obvious upward trend (there’s a reason why the nine warmest years on record have all occurred between 1998 and 2008).

DesmogBlog Breaks DSCOVR Story in Nature

DesmogBlog was contacted this month by Nature – the most prestigious science journal in the world  – about our latest posting on the Deep Space Climate Observatory

It seems their editors were interested in the news we broke that the Air Force was considering launching this $100 million mothballed spacecraft – minus the Earth observing instruments.

Last week they published an 800 word article based on information we provided to them about this bizarre story.

Alas, our extensive research on the DSCOVR mission was not mentioned in the Nature article, but such is the lot of a blogger.

More importantly, the exposure provided by this piece in one of the premier journals in the world will hopefully light a fire under NASA to not to kill this vital mission.

DSCOVR Mission May Be Gutted

Here is the latest twist in the bizarre story about the Deep Space Climate Observatory (DSCOVR). Apparently, the US Air Force is in discussions with NASA to take over the mission, with one important catch: that all the Earth observing instruments be removed.

It seems the Air Force is more interested in looking at the Sun than our warming planet and plans are being made to send the spacecraft one million miles distant – only to look the other way.

Check out NASA's new science blog

When it comes to climate science, its usually best to talk to climate scientists. And a new blog set up by NASA at the Jet Propulsion Laboratory is a welcomed voice in the social media arena.

While climate isn't the only focus of the new JPL blog, so far there has been a pretty heavy focus on the issue. So grab the JPL blog's RSS feed and keep up-to-date on the latest in climate change science through the eyes of an actual climate scientist.

ClimateAudit Endorses 1988 Climate Change Projections

Next to the much-(and usually falsely)-maligned hockey stick graph, one of the denier community's favorite targets has been a series of climate modeling graphs that NASA's James Hansen produced in 1988.

Notwithstanding that Hansen has done two more decades of world-leading research, people like Stephen McIntyre of the quibbler site ClimateAudit.Org have obsessed endlessly about the purported “flaws” in that graph series.

Which is why it's so surprising to see McIntyre accepting Hansen's work now.

Where's the best place for wind power?

Generating electricity from the power of the wind is one of the many ways we can begin to wean North America off its reliance on dirty fuels like coal that produce massive amounts of heat-trapping greenhouse gas.

So where are the windiest places in the world that can power our lives?

NASA scientists have been creating maps using nearly a decade of data from NASA's QuikScat satellite that reveal ocean areas where winds could produce energy.

Lorne Gunter: Incompetent or Lying? Either Way, Worth Firing

An earlier post of the errors/misrepresentations in a recent Lorne Gunter column in the National Post has attracted a host of comments and a few that further debunk Gunter’s passionately inaccurate talking points.

DeSmog reader Dave Clark, for example, offers this:

Yet another whopper from Gunter:
