IPCC 95% Certain That Humans Are Dominant Cause Of Global Warming

So what will the Greedy Lying Bastards (that would be the climate change deniers) say about this? From BBC News:

A UN panel has released part one of its six-yearly update on the state of the Earth’s climate. The much-anticipated report by the Intergovernmental Panel on Climate Change (IPCC) says that with 95% certainty, humans are the dominant cause of global warming since the 1950s. The BBC News website’s science editor Paul Rincon breaks down some of the document’s key findings.

Part one of the IPCC’s fifth assessment report (AR5) on the Earth’s climate opens with the message that we are seeing changes in the climate system unprecedented in records spanning hundreds of years.

With this scene-setting out of the way, the report says the period from 1983-2012 in the Northern Hemisphere was likely the warmest 30-year period of the last 1,400 years. Each of the last three decades has got successively warmer, and these decades have all been warmer than any of the preceding decades since 1850.

Climate Panel Claims ‘Near Certainty’ of Man-Made Global Warming

The results are in and they aren’t good, for anyone, climate deniers especially. The New York Times reports on the IPCC‘s dour assessment of climate change:

An international panel of scientists has found with near certainty that human activity is the cause of most of the temperature increases of recent decades, and warns that sea levels could conceivably rise by more than three feet by the end of the century if emissions continue at a runaway pace.

The scientists, whose findings are reported in a draft summary of the next big United Nations climate report, largely dismiss a recent slowdown in the pace of warming, which is often cited by climate change doubters, attributing it most likely to short-term factors.

The report emphasizes that the basic facts about future climate change are more established than ever, justifying the rise in global concern. It also reiterates that the consequences of escalating emissions are likely to be profound.

Debunking the “Great Global Warming Swindle”

Peter Sinclair:

When the Great Global Warming Swindle was first broadcast – climate deniers thought that at last they had the definitive polemic to beat back the forces of science and reason…..

The Emerging Speculative Genre Of “Cli Fi”

climate fiction

Is environmental change poised to thrust us into new worlds? NPR writes:

Nathaniel Rich’s Odds Against Tomorrow is the latest in what seems to be an emerging literary genre. Over the past decade, more and more writers have begun to set their novels and short stories in worlds, not unlike our own, where the Earth’s systems are noticeably off-kilter. The genre has come to be called climate fiction — “cli-fi,” for short.

“I think we need a new type of novel to address a new type of reality,” says Rich, “which is that we’re headed toward something terrifying and large and transformative. And it’s the novelist’s job to try to understand, what is that doing to us?” As far as Rich is concerned, climate change itself is a foregone conclusion. The story — the suspense, the romance — is in how we deal with it.

Of course, science fiction with an environmental bent has been around since the 1960s (think J.G.

Rainforests Adapting to Global Warming

Man is doing his best to destroy the Earth’s resources, but nature has a way of adapting and resisting. James Fleure reports for Science Recorder:

A team of researchers, led by Dr. Chris Huntingford from the Centre for Ecology & Hydrology, has discovered more evidence of rainforest resilience to global warming. Their findings reveal that tropical forests are less likely to lose biomass due to global warming than climatologists previously thought. According to the BIOMASS Energy Centre, biomass is biological material derived from living, or recently living organisms.

Researchers undertook the most comprehensive study yet of the risk of tropical forest dieback due to global warming. They contend that their results have significant implications for the role of tropical rainforests in the global climate system and carbon cycle.

Researchers utilized computer simulations with 22 climate models to examine the response of the tropical forests in the Americas, Africa and Asia to greenhouse-gas-induced climate change.

Wall Street Exploring Ways To Profit From Global Warming

Turning lemons into really pricy lemonade. Bloomberg on the investment companies banking on massive windfalls as the planet heats:

Investing in climate change used to mean putting money into efforts to stop global warming. Now some investors are taking another approach. Working under the assumption that climate change is inevitable, they’re investing in businesses that will profit as the planet gets hotter.

Derivatives that help companies hedge against abnormal weather and natural catastrophes are drawing increased interest from big players. In January, KKR bought a 25 percent stake in Nephila Capital, an $8 billion Bermuda hedge fund that trades in weather derivatives.

Drought is helping spur business at Water Asset Management. The New York hedge fund, which has about $400 million under management, buys water rights and makes private equity and stock market investments in water treatment companies.

Ole Christiansen is also investing to take advantage of rising temperatures. “Last summer we were exploring in south Greenland, mainly for gold,” says the chief executive officer of NunaMinerals (NUNA), a local mining company.

Research Suggests Volcanoes Are Tamping Down Global Warming

Via the University of Colorado Boulder:

A team led by the University of Colorado Boulder looking for clues about why Earth did not warm as much as scientists expected between 2000 and 2010 now thinks the culprits are hiding in plain sight — dozens of volcanoes spewing sulfur dioxide.

The study results essentially exonerate Asia, including India and China, two countries that are estimated to have increased their industrial sulfur dioxide emissions by about 60 percent from 2000 to 2010 through coal burning, said lead study author Ryan Neely, who led the research as part of his CU-Boulder doctoral thesis. Small amounts of sulfur dioxide emissions from Earth’s surface eventually rise 12 to 20 miles into the stratospheric aerosol layer of the atmosphere, where chemical reactions create sulfuric acid and water particles that reflect sunlight back to space, cooling the planet.

Neely said previous observations suggest that increases in stratospheric aerosols since 2000 have counterbalanced as much as 25 percent of the warming scientists blame on human greenhouse gas emissions.

Earth Goes From Coldest Decade To Hottest In Just One Century

Cavell Glacier with Crevices and Annual RingsNever mind what’s causing it, it’s gettin’ hot up in here! From CNN:

Global warming has propelled Earth’s climate from one of its coldest decades since the last ice age to one of its hottest — in just one century.

A heat spike like this has never happened before, at least not in the last 11,300 years, said climatologist Shaun Marcott, who worked on a new study on global temperatures going back that far.

“If any period in time had a sustained temperature change similar to what we have today, we would have certainly seen that in our record,” he said. It is a good indicator of just how fast man-made climate change has progressed.

A century is a very short period of time for such a spike.

It’s supposed to be cold
The Earth was very cold at the turn of the 20th century. The decade from 1900 to 1909 was colder than 95% of the last 11,300 years, the study found.
