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.

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.

Researchers Warn Against Abrupt Stop of Geoengineering Method

It could be dangerous if we start injecting sulfate particles into the atmosphere to curb global warming and then suddenly stop.

Via EurekaAlert:

As a range of climate change mitigation scenarios are discussed, University of Washington researchers have found that the injection of sulfate particles into the atmosphere to reflect sunlight and curb the effects of global warming could pose a severe threat if not maintained indefinitely and supported by strict reductions in greenhouse gas (GHG) emissions.

The new study, published today, 18 February, in IOP Publishing’s journal Environmental Research Letters, has highlighted the risks of large and spatially expansive temperature increases if solar radiation management (SRM) is abruptly stopped once it has been implemented.

SRM is a proposed method of geoengineering whereby tiny sulfate-based aerosols are released into the upper atmosphere to reflect sunlight and cool the planet. The technique has been shown to be economically and technically feasible; however, its efficacy depends on its continued maintenance, without interruption from technical faults, global cooperation breakdown or funding running dry.

How the U.S. Exports Global Warming

AirPollutionSourceSad but not surprising that as the Greedy Lying Bastards of Big Carbon are being exposed and opposed in the United States, they are turning to less developed countries to make their megabucks. Tim Dickinson reports for Rolling Stone:

The greening of American energy is both real and profound. Since President Obama took office, the nation’s solar capacity has increased more than tenfold. Wind power has more than doubled, to 60,000 megawatts – enough to power nearly 20 million homes. Thanks to aggressive new fuel-efficiency standards, the nation’s drivers are burning nearly 5 billion fewer gallons of gasoline a year than in 2008. The boom in cheap natural gas, meanwhile, has disrupted the coal industry. Coal-power generation, though still the nation’s top source of electricity, is off nearly 20 percent since 2008. More than 150 coal plants have already been shuttered, and the EPA is expected to issue regulations in June that will limit emissions from existing coal facilities.

NYU Scientists Tie Antarctica Warming to Natural Cycle in Tropical Atlantic

Scientist at New York University have added another wrinkle to the contentious topic of climate change…

Via Christian Science Monitor:

Rapid warming along the Antarctic Peninsula and puzzling shifts in the distribution and extent of winter sea ice at the bottom of the world appear to have their roots in a natural climate swing centered in the tropical Atlantic, according to a new study by researchers at New York University.

The warming of the region is of concern because of its implications for sea-level rise, while the shifting and slight increase in winter sea ice has become a favorite talking-point among many of global warming’s political skeptics.

The climate swing the researchers discussed, known as the Atlantic Multidecadal Oscillation (AMO), shows up as a cycle of warmer, then colder-than-normal sea-surface temperatures. The cycle repeats itself once every 40 to 80 years or so, with cooler or warmer temperatures lasting for periods of 20 to 40 years or more.

What’s Driving the Polar Vortex?

Robert Hunziker writes at CounterPunch:

Climate change is not hot weather, and it is not cold weather. Those conditions have been around for eons.

Climate change is extreme anomalous weather conditions, like 100-year floods every few years rather than once every 100 years, e.g., Eastern Europe in 2013, or torrential downpours equivalent to annual rainfall levels but within one week, like Colorado in 2013, or embedded droughts that last for months, like Russia in 2010 when grain exports were halted, or subzero temperatures throughout North America in January 2014 because of anomalous jet streams, i.e. climate change conditions.

All of these extreme weather conditions that in years past happened on the odd occasion are now happening with increasing frequency, ferocity, and longevity.  These conditions are becoming the norm and turn nasty by embedding for long duration because of climate change conditions.

As such, the saying “a 100-year flood” has become passé.

The Greedy Lying Bastards’ Favorite ‘Global Cooling’ Story

It turns out that the unwitting hero of the climate change deniers (a/k/a Greedy Lying Bastards) is one Peter Gwynne. Who, you may well ask? Daily Climate via Scientific American tells his story:

Temperatures have plunged to record lows on the East Coast, and once again Peter Gwynne is being heralded as a journalist ahead of his time. By some.

Gwynne was the science editor of Newsweek 39 years ago when he pulled together some interviews from scientists and wrote a nine-paragraph story about how the planet was getting cooler.

newsweek global cooling

Ever since, Gwynne’s “global cooling” story – and a similar Time Magazine piece – have been brandished gleefully by those who say it shows global warming is not happening, or at least that scientists – and often journalists – don’t know what they are talking about.

Fox News loves to cite it. So does Rush Limbaugh. Sen. James Inhofe, R-Okla., has quoted the story on the Senate floor.

Global Warming Or A New Ice Age?

Via the National:

For many of us, the debate over the reality of climate change never goes beyond wondering if it can explain a recent bout of freakish weather.

Yet for many of the hundreds of thousands of Filipinos living in the UAE the debate has taken a tragically personal turn.

Yeb Sano, leader of the Philippines delegation to November’s UN climate conference in Warsaw, doubtless spoke for many when he implicated global warming for the Super Typhoon Haiyan, which has so far claimed more than 5,000 lives and left 500,000 homeless.

Mr Sano’s speech was made all the more poignant by the fact that exactly a year ago, his delegation appealed for action to combat global warming while his nation was being battered by another typhoon, causing a then-unprecedented disaster on the southern island of Mindanao.

He was close to tears as he called on those still sceptical about climate change to “get off your ivory tower and away from the comfort of your armchair” to witness the evidence.

Climate Change Deniers Backed by Secret Network of Billionaires

greedy lying coverThe Greedy Lying Bastards are being exposed for what they are by the liberal media, but will governments resist the financial clout of the “secret network of billionaires” described by Lindsay Abrams at Alternet, who herself is reporting on this article by Suzanne Goldenberg in The Guardian:

Conservative groups may have spent up to $1bn a year on the effort to deny science and oppose action on climate change, according to the first extensive study into the anatomy of the anti-climate effort.

The anti-climate effort has been largely underwritten by conservative billionaires, often working through secretive funding networks. They have displaced corporations as the prime supporters of 91 think tanks, advocacy groups and industry associations which have worked to block action on climate change. Such financial support has hardened conservative opposition to climate policy, ultimately dooming any chances of action from Congress to cut greenhouse gas emissions that are warming the planet, the study found.
