[T]he poles are warming faster than any part of the planet and rapid ice melt is being observed at increased rates in Antarctica. According to a new study, ice shelves in West Antarctica have lost as much as 18 percent of their volume over the last two decades, with rapid acceleration occurring over the last decade.
…While the polar regions are feeling the most severe temperature changes brought on by the rise in greenhouse gas concentrations in the atmosphere, areas across the globe are setting record highs at a much faster rate than record lows. Since 2010, 46 nations or territories out of 235 have set or tied record highs. Only four have set record lows.
Time series of five-year global temperature averages, mapped from 1880 to 2014, as estimated by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.
The year 2014 ranks as Earth’s warmest since 1880, according to two separate analyses by NASA and National Oceanic and Atmospheric Administration (NOAA) scientists.
The 10 warmest years in the instrumental record, with the exception of 1998, have now occurred since 2000. This trend continues a long-term warming of the planet, according to an analysis of surface temperature measurements by scientists at NASA’s Goddard Institute of Space Studies (GISS) in New York.
In an independent analysis of the raw data, also released Friday, NOAA scientists also found 2014 to be the warmest on record.
While scientists expect temperatures to fluctuate from year to year, the average temperature of the planet as a whole has warmed by about 1.4 degrees Fahrenheit (0.8 degrees Celsius) since 1880. This trend is largely driven by increasing human emissions of carbon dioxide and other greenhouse gases into the atmosphere.
“Interstellar,” Christopher Nolan’s ninth film, is the most ambitious thing he’s ever done (this is the director of “Inception” we’re talking about here). It’s a $165 million visual masterpiece about an ambitious attempt to save the human race, trapped on a dying Earth. The science is shaky to say the least, and there’s an excess of melodrama IMHO. But it’s well worth seeing. Features include:
- Big ideas
- Terrific cast & acting
- Plenty of plot twists
- No sound in space (like “2001: A Space Odyssey”)
- A wormhole to another galaxy
- Time dilation
- A gargantuan black hole (which doubles as a plot hole)
And Matthew McConaughey gets to say, “We don’t have time to argue about relativity right now.”
NOAA’s GOES-13 satellite captured this image of the massive Superstorm Sandy on October 28, 2012.
[O]n Sunday, the Intergovernmental Panel On Climate Change released a Synthesis Report detailing the dangers of climate change. Hundreds of scientists spent the last five years preparing this final report, which says that carbon pollution must be slashed now or risk “severe, pervasive and irreversible impacts for people and ecosystems.”
None of the network Sunday shows mentioned this latest report or its stark findings.
It’s not just a media fail. Has any candidate in tomorrow’s election mentioned climate change as a campaign issue?
Take a look at the damage from Superstorm Sandy in the before-and-after aerial imagery. This one storm two years ago impacted more than a dozen states along the eastern seaboard, causing $65 billion in damage. A major factor in the disaster was the higher sea level. Climate models predict that sea level will rise an additional two to three feet over the next century.
Because cable TV news has this event blacked out, even MSNBC. It’s happening in Manhattan, right under the noses of the media elite, and they won’t report about it.
Tom Engelhardt: Is Climate Change a Crime Against Humanity?
From two scientific studies just released, for example, comes the news that the West Antarctic ice sheet, one of the great ice accumulations on the planet, has now begun a process of melting and collapse that could, centuries from now, raise world sea levels by a nightmarish 10 to 13 feet. That mass of ice is, according to the lead authors of one of the studies, already in “irreversible retreat,” which means — no matter what acts are taken from now on — a future death sentence for some of the world’s great cities. (And that’s without even the melting of the Greenland ice shield, not to speak of the rest of the ice in Antarctica.)
UPDATE: OK, MSNBC is now reporting that well over 100,000 marchers are on the streets. They have a reporter doing a live shot now (10:30 am).
NEW YORK — More than 400,000 people turned out for the People’s Climate March in New York City on Sunday, just days before many of the world’s leaders are expected to debate environmental action at the United Nations climate summit.
One of the comments in a post on global warming pointed us to what may well be the quintessential example of reality denial. It was in fact so good that I thought it was worth its own top level post. Lets have a look shall we?
Writing as a “contributor” of some kind at Forbes, one Larry Bell decides to take John Kerry to task for supporting science.
Tonight I watched the terrific documentary “Bidder 70″ (2012) by Beth & George Gage, that tells the story of what happened after Tim DeChristopher disrupted an illegal BLM oil & gas lease auction in the last days of the Bush administration, December 19, 2008. It’s on Netflix now!
The message of the film is that in corporate-controlled America, the only power we have as individuals is the power of not backing down and not going away. DeChristopher provided everyone with a perfect example of how we can do that. That’s why the PTB had to send him to federal prison. Not the Wall Street fraudsters who crashed the economy. Not the greedy oil companies who polluted the Gulf of Mexico. Not the right-wing protesters who defy the BLM by riding ATVs in the wilderness. Not the millionaire ranchers who refuse to pay their grazing fees on public land. Anybody who’s onboard with the corporatist agenda has nothing to fear.
Judge Dee Benson actually admitted that he sentenced Tim DeChristopher to two years imprisonment not for anything he did (“bid-walking” in a BLM lease auction is so common they have a name for it, and it has never been prosecuted before) — it was for what he said. The First Amendment does not protect you if you go against Corporate America.
Neil deGrasse Tyson has talked about climate frequently already in previous episodes of “Cosmos,” but this Sunday, the entire show was about it.
His main argument points out that we’ve been aware of the greenhouse effect since at least 1896, and we have known about the value of solar power since at least 1878. There is no technological or practical reason why we can’t save our planet.
From Climate Central:
In 1958, Charles David Keeling began making daily measurements of the concentration of atmospheric carbon dioxide (CO2) at the Mauna Loa Observatory on the Big Island of Hawaii. These measurements were begun as part of a one-year initiative, the International Geophysical Year, but because of Keeling’s persistence, the daily record has continued through the present, almost without interruption. The Mauna Loa record, now known as the Keeling Curve, continues to be collected under the direction of Keeling’s son, Ralph.
Last year, atmospheric carbon dioxide briefly crossed 400 parts per million for the first time in human history. However, it didn’t cross that threshold until mid-May. This year’s first 400 ppm reading came a full two months earlier this past week and the seeming inexorable upward march is likely to race past another milestone next month.
“We’re already seeing values over 400. Probably we’ll see values dwelling over 400 in April and May. It’s just a matter of time before it stays over 400 forever,” said Ralph Keeling in a blog post.
To preserve a livable planet, climate scientists tell us we must reduce the amount of CO2 in the atmosphere from its current level of 400 parts per million to below 350 ppm.
Right-wing Republicans remain unconcerned. Recently Congresswoman Marsha Blackburn (R-TN), the vice chair of the notoriously anti-climate change House Energy and Commerce Committee, said on “Meet the Press”: “Now, you know, when you look at the social cost of carbon, and there is a lot of ambiguity around that, what you also need to be doing is looking at the benefits of carbon and what that has on increased agricultural production.”
“The President should realize that Congress has taken action” on climate change policies, Blackburn said. “We have said no.”
World’s Oldest Direct Measure Of Atmospheric CO2 May Lose Its Funding
“The good thing about science is that it’s true whether or not you believe in it.”

Be sure and watch “Cosmos: A Spacetime Odyssey.”
MSNBC’s Ed Schultz reversed his support for the proposed Keystone XL pipeline on Wednesday and said the United States shouldn’t allow it to be built. Last month he called the pipeline “a step in the right direction when it comes to energy independence.”
Of course, Keystone XL won’t be a pipeline TO the USA. It’s a pipeline THROUGH the USA to overseas export. It’s likely to cause a gasoline price hike in this country. What do we get from this pipeline? More groundwater pollution, and more climate change.
President Obama could stop this pipeline all by himself. The right-wing is clearly worried, and the Faux News crowd is even claiming that Keystone XL approval would be the answer to the crisis in the Ukraine!
