House GOP Tells Commie Pentagon To Forget About All That “Global Warming” Nonsense

pentagonMaybe they can ban differing kinds of camo next.  You know, to save money.  Abby Zimet writes at CommonDreams:

As even our historically less-than-progressive military increasingly identifies climate change as a threat to national security, House Republicans in their infinite wisdom last week passed a bill blocking funding for any Pentagon program that tries to do anything about saving the planet that pretty much everyone at this point agrees is in danger. Because climate change is just a “political hot item of the day” that “has nothing to do with winning battles” and “is it wise to continue to violently disrupt a culture which is fueled by tradition and a fierce warrior ethos by forcing them to constantly adjust to the popular political trends of the day?” when anyway it was Democrats who “snuck some language into the National Defense Authorization Act which got our military considering the ‘threat’ of climate change” even though “the link between extreme weather and global warming is (a) very shaky foundation upon which to reshape America’s defense strategy” and really we need to free up the military to “concentrate on addressing real man-made threats to our national independence…a mission they can actually do something about!” Noting “the flat earth society is at it again,” critics in the House called the bill “science denial at its worst.” Hopefully, it will fail in the Senate.

Increasing CO2 Will Lead to ‘Most Significant Health Threat Ever Shown to be Associated with Climate Change’

Wheat Ear milk fullOf all the threats posed by climate change, who would have guessed that “[g]iven that an estimated 2 billion people suffer from zinc and iron deficiencies, resulting in a loss of 63 million life years annually from malnutrition, the reduction in these nutrients represents the most significant health threat ever shown to be associated with climate change”?

Todd Datz, Harvard School of Public Health Communications, reports for the Harvard Gazette on a new study led by HSPH:

At the elevated levels of atmospheric CO2 anticipated by around 2050, crops that provide a large share of the global population with most of their dietary zinc and iron will have significantly reduced concentrations of those nutrients, according to a new study led byHarvard School of Public Health (HSPH). Given that an estimated 2 billion people suffer from zinc and iron deficiencies, resulting in a loss of 63 million life years annually from malnutrition, the reduction in these nutrients represents the most significant health threat ever shown to be associated with climate change.

Climatologist, author, and former NASA scientist Dr. Roy Spencer offers ten good skeptical arguments against global warming. Raw Story published a response to this via The Guardian, if you’d like to read it.

via Top Ten Good Skeptical Arguments « Roy Spencer, PhD.

As suggested by a friend, I’m following up my Top Ten bad global warming arguments list with a Top Ten good arguments list. These are in no particular order, and I might have missed something important.

These ten were just off the top of my head….there’s no telling what might be lingering deeper in my brain.

I have avoided specific alternative causal mechanisms of natural climate change, because I view them individually as speculative. But taken as a whole, they represent a class of unknowns that can’t be just swept under the rug just because we don’t understand them.

For some reason, all of these ended up being phrased as questions, rather than statements.

The myth of the 97% climate change consensus

What is the origin of the false belief – constantly repeated by President Obama, the media and others – that almost all scientists agree about global warming?

Claims continue to be made that “97% of scientists agree that climate change is real, man-made and dangerous.” That’s what Secretary of State John Kerry told graduating Boston College students. It’s what President Obama said in his State of the Union address and a recent tweet.

There’s just one problem – aside from the fact that this assertion is being used to help justify policies and regulations that are closing down fossil fuel power plants and crippling our economy. The claim is completely bogus. As Heartland Institute president Joe Bast and climate scientist Roy Spencer make clear in this article, the papers used to create and perpetuate the 97% claim are seriously and fundamentally flawed. The alleged consensus simply does not exist; much less does it represent anything remotely approaching 97%.

Global Extinction Within One Lifetime?

From 2012, Michael Brown writing at the Ecologist:

It is now widely accepted that human-induced climate change is a potentially dangerous issue. In a  year (2012) when 15,000 temperature records were set in March alone and many freak weather patterns continued to cause drought and flooding across the globe the danger seems increasingly real and undeniable.

The latest addition to these concerns is the release of methane gas from the Arctic permafrost. Recently it was announced that the Russian research vessel Academician Lavrentiev had made discoveries of hundreds of methane gas eruptions in a 10,000 square mile area of the Arctic Ocean. Russian researcher Dr Igor Semiletov stated:  “These are methane fields on a scale not seen before. We found more than 100 fountains, some more than a kilometre across. The emissions went directly into the atmosphere.”

Methane is a greenhouse gas that is estimated to be about 20 times more potent than carbon dioxide (CO2).

Physics Professor Says That Odds that Global Warming Is Due to Natural Factors Nil

There: That’ll settle that argument. Right?

An analysis of temperature data since 1500 all but rules out the possibility that global warming in the industrial era is just a natural fluctuation in the earth’s climate, according to a new study by McGill University physics professor Shaun Lovejoy. The study, published online April 6 in the journal Climate Dynamics, represents a new approach to the question of whether global warming in the industrial era has been caused largely by man-made emissions from the burning of fossil fuels. Rather than using complex computer models to estimate the effects of greenhouse-gas emissions, Lovejoy examines historical data to assess the competing hypothesis: that warming over the past century is due to natural long-term variations in temperature.

“This study will be a blow to any remaining climate-change deniers,” Lovejoy says. “Their two most convincing arguments – that the warming is natural in origin, and that the computer models are wrong – are either directly contradicted by this analysis, or simply do not apply to it.”

Lovejoy’s study applies statistical methodology to determine the probability that global warming since 1880 is due to natural variability.

The Climate Change Deniers Have Won

What’s with the “let us hope” bullshit?  Nick Cohen writes at the Observer:

The American Association for the Advancement of Science came as close as such a respectable institution can to screaming an alarm last week. “As scientists, it is not our role to tell people what they should do,” it said as it began one of those sentences that you know will build to a “but”. “But human-caused climate risks abrupt, unpredictable and potentially irreversible changes.”

In other words, the most distinguished scientists from the country with the world’s pre-eminent educational institutions were trying to shake humanity out of its complacency. Why weren’t their warnings leading the news?

In one sense, the association’s appeal was not new. The Royal Society, the Royal Institution, Nasa, the US National Academy of Sciences, the US Geological Survey, the IPCC and the national science bodies of 30 or so other countries have said that man-made climate change is on the march.

Journal Pulls Paper Due to “Legal Context” Created By Climate Contrarians

GLOBAL WARMING / CLIMATE CHANGE IS A HOAX

Some anti climate change “conspiracy” theorists blame everyone but themselves for looking bad. A strange loop happens, then another strange loop, and then academic freedom is limited.

via ars technica

The initial paper produced results that weren’t entirely surprising. By surveying visitors to climate blogs, its authors found that free-market fans tended to reject scientific findings that had potential regulatory implications, something that’s been found by a variety of other researchers. But it also found that there is a population of people who doubt scientific findings simply because they tended to doubt nearly everything, ascribing a variety of things—the Moon landings, the World Trade Center attacks, etc.—to conspiracies. This might seem surprising, but the results held up when the same authors extended the study to the US population in general.

What’s probably less surprising is that some of the subjects of the initial paper responded with a new set of conspiracy theories, focused on the paper itself.

Global Warming Will Cause Widespread Conflict, Displace Millions and Devastate Global Economy

Alicante(30-09-1997)Coming soon! The Independent reveals the latest findings of the UN’s IPCC in advance of its next report, and it is depressing reading indeed:

Climate change will displace hundreds of millions of people by the end of this century, increasing the risk of violent conflict and wiping trillions of dollars off the global economy, a forthcoming UN report will warn.

The second of three publications by the UN’s Intergovernmental Panel on Climate Change, due to be made public at the end of this month, is the most comprehensive investigation into the impact of climate change ever undertaken. A draft of the final version seen by The Independent says the warming climate will place the world under enormous strain, forcing mass migration, especially in Asia, and increasing the risk of violent conflict.

Based on thousands of peer-reviewed studies and put together by hundreds of respected scientists, the report predicts that climate change will reduce median crop yields by 2 per cent per decade for the rest of the century – at a time of rapidly growing demand for food.

Volcanoes Contribute to Recent Global Warming ‘Hiatus’

Volcanoes, the cause of global warming?  Au contraire, they’re an antidote!  Via ScienceDaily:

Volcanic eruptions in the early part of the 21st century have cooled the planet, according to a study led by Lawrence Livermore National Laboratory. This cooling partly offset the warming produced by greenhouse gases.

Despite continuing increases in atmospheric levels of greenhouse gases, and in the total heat content of the ocean, global-mean temperatures at the surface of the planet and in the troposphere (the lowest portion of Earth’s atmosphere) have shown relatively little warming since 1998. This so-called ‘slow-down’ or ‘hiatus’ has received considerable scientific, political and popular attention. The volcanic contribution to the ‘slow-down’ is the subject of a new paper appearing in the Feb. 23 edition of the journal Nature Geoscience.

Volcanic eruptions inject sulfur dioxide gas into the atmosphere. If the eruptions are large enough to add sulfur dioxide to the stratosphere (the atmospheric layer above the troposphere), the gas forms tiny droplets of sulfuric acid, also known as “volcanic aerosols.” These droplets reflect some portion of the incoming sunlight back into space, cooling Earth’s surface and the lower atmosphere.
