Turns out that Faux News Channel was wrong about climate change. There wasn’t any ‘pause’ or ‘hiatus’ in global warming. Surprised? Also wrong– presidential candidate Rafael (“Ted”) Cruz, who said this just over three months ago:
“The last 15 years, there has been no recorded warming. Contrary to all the theories that – that they are expounding, there should have been warming over the last 15 years. It hasn’t happened.”
It turns out that using the global mean surface temperature as the primary yardstick for climate change masked the actual trend. Also temperature fluctuations due to natural variation led to some speculation about “missing heat” that actually wasn’t missing at all, it was in the oceans.
Maybe NOW we can cancel all the “debates” about whether climate change is happening, and start talking about how to adapt to it. Prevention is no longer an option, but possibly we can mitigate warming or limit the duration.
Federal scientists say there never was any global warming “pause”
[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.
“So it is a bad year for the Earth and an equally bad year for the politicians, talk show radio ‘scientists’, climate-denial funders, and second rate scientists who told us not to worry,” as climate expert Professor John Abraham told me. “They told us global warming had stopped nearly two decades ago. The problem is, science and climate change marched forward. Perhaps next time we will believe the real scientists.”
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.
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.
The Environmental Protection Agency’s proposed coal regulations have angered Tea-GOP right-wingers who deny climate science.

A standoff with Senate Democrats and the president over funding for the EPA and Interior Department could set the stage for a budget showdown, risking a partial government shutdown. Here we go again.
In an interview with Bloomberg, Rep. Mike Simpson (R-ID) said the House Appropriations Committee may include a rider to the bill that’s necessary to keep the Department of Interior and EPA open after the fiscal year’s end in September.
…A partial shutdown to the Interior and EPA might seem like it would cause less damage to the GOP than the full-scale shutdown of 2013. But remember that includes national parks, which was one of the most visible and unpopular consequences from last year’s shutdown. And the EPA is charged with a lot besides fighting climate change, like protecting our drinking water and overseeing cleanup of toxic waste sites.
Senate Majority Leader Harry Reid (D-NV) has warned the Tea-GOP not to shut down the government over climate change. But really, if they do it right before the midterm elections it might do more good than harm.
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.”

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!

Keystone XL is a “go.” Count on Secretary of State Kerry to do the right thing – for the industry. The planet will have to take its chances.

It’s classic. Wait till late on a Friday to announce a reprehensible decision in hopes of minimizing the uproar in response. But the climate crisis doesn’t take weekends off.
…”Significant impacts to most resources are not expected along the proposed Project route assuming the following,” reads the State Department report, before listing a series of improbable assumptions.
They say it’s just one pipeline. But the point is we have to say no to ALL the pipelines and leave fossil fuels in the ground.

Sam Stein: So What Exactly Is Obama’s Red Line On Keystone XL?
A baby born in the new year can expect to live in a world that suffers the effects of catastrophic climate change, according to an article in The Guardian based on a new scientific study published in the journal Nature.
Professor Steven Sherwood at the University of New South Wales in Australia, who led the new research, said that unless emissions of greenhouse gases are cut, the planet would heat up by a minimum of 4C by 2100. The study found that as the planet heats, fewer sunlight-reflecting clouds form, causing temperatures to rise further in an upward spiral.
“4C would likely be catastrophic rather than simply dangerous,” Sherwood told the Guardian. “For example, it would make life difficult, if not impossible, in much of the tropics, and would guarantee the eventual melting of the Greenland ice sheet and some of the Antarctic ice sheet,” with sea levels rising by many meters as a result.
…”Climate skeptics like to criticize climate models for getting things wrong, and we are the first to admit they are not perfect,” said Sherwood. “But what we are finding is that the mistakes are being made by the models which predict less warming, not those that predict more.”
For the sake of argument, it’s customary to say that climate models only predict what is likely to happen unless we do something fast. I am starting to doubt that there is anything that can be done now to prevent catastrophic climate change, or even slow it down. This is because certain tipping points, for example rapid melting of the Greenland ice sheet, may have already been reached. Once a trigger is pulled, it cannot be un-pulled. The bullet is on its way.
Chris Hayes is the first cable host to interview Tim DeChristopher. Rachel Maddow announced such an interview a couple of years ago, but then substituted some hack from EarthJustice who didn’t approve of civil disobedience.
My favorite part is when Tim explains that it’s already too late to avoid the tipping points that trigger drastic climate change, but that makes it even more urgent to reform our political system. The current corrupt regime won’t be able to cope with a planetary emergency.
The Republican members of the Senate Environment and Public Works Committee boycotted today’s hearing on Gina McCarthy, President Obama‘s pick to head the Environmental Protection Agency (EPA). Lacking the votes to defeat approval of McCarthy’s nomination, they decided to deprive the committee of a quorum. Apparently Republicans are worried that the EPA might enforce the Clean Air Act, thus helping to reduce the effects of climate change.
Chairwoman Barbara Boxer (D-CA) was not happy.
“Their opposition, even to allowing us to vote, shows how outside the mainstream they are, it shows how obstructionist they are,” the senator continued. “It shows how their pledge to do better with women voters is false. How could you have a more qualified woman than Gina McCarthy? This is outrageous.”
“They’re fringe, they’re out of the mainstream,” she reiterated — and trying to impose their “pro-pollution stance” on the Obama administration. Boxer further noted that they’d be examining their parliamentary options, which would include potentially changing committee rules.
To the opposition, Boxer offered some advice: Take a page out of the mainstream Republicans’ playbook and “get out of the fringe lane.”
McCarthy has already answered over 1,000 written questions from GOP committee members, more than any other Obama nominee.
This is how the tail wags the dog in the U.S. Senate. Nice work, GOP
UPDATE: An instrument near the summit of Mauna Loa in Hawaii has recorded a long-awaited climate milestone: the amount of carbon dioxide in the atmosphere there has exceeded 400 parts per million (ppm) for the first time in 55 years of measurement—and probably more than 3 million years of Earth history.
350 parts per million is what many scientists, climate experts, and progressive national governments consider to be the safe upper limit for CO2 in our atmosphere.
