Odds That Global Warming is Due to Natural Factors: Slim To None

Sun, 2014-04-13 20:22 — Kathy Gilbeaux

publications.mcgill.ca - April 12, 2014

Statistical analysis rules out natural-warming hypothesis with more than 99 per cent certainty

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 physics professor Shaun Lovejoy.

The study, published online on 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. . .

. . . Lovejoy’s study applies statistical methodology to determine the probability that global warming since 1880 is due to natural variability. His conclusion: the natural-warming hypothesis may be ruled out “with confidence levels great than 99 per cent, and most likely greater than 99.9 per cent.”

Shell, Adidas, And 70 Other Companies Call On Governments To Cap Carbon At 1 Trillion Tons

Royal Dutch Shell, Adidas, Unilever, and some 70 other companies released a communiqué urging world governments to keep carbon emissions since the industrial revolution to a cumulative of 1 trillion metric tons. This is the emissions cap needed to keep warming below two degrees Celsius and avoid catastrophic impacts of climate change, according to the latest Intergovernmental Panel on Climate Change (IPCC) report, which for the first time calls for a trillion ton cap. We have already surpassed the halfway mark and are somewhere around 578,935,750,000 tonnes of carbon at the moment.

Leaked text of blockbuster report says changes in climate have already caused impacts on natural and human systems

theguardian.com - by Suzanne Goldenberg - March 28, 2014

Climate change has already left its mark "on all continents and across the oceans", damaging food crops, spreading disease, and melting glaciers, according to the leaked text of a blockbuster UN climate science report due out on Monday.

Government officials and scientists are gathered in Yokohama this week to wrangle over every line of a summary of the report before the final wording is released on Monday – the first update in seven years.

Big Facts: Climate Impacts on People

Thu, 2014-03-27 20:22 — Kathy Gilbeaux

ccafs.cgiar.org - by Simon Bager - March 26, 2014

Millions of people around the world already struggle to achieve food security and climate change is set to make those challenges even harder. It is perhaps humanity’s most pressing challenge, as we seek to nourish more than nine billion people by 2050.

sigma - No 01/2014 Natural Catastrophes and Man-Made Disasters in 2013

Wed, 2014-03-26 17:28 — Kathy Gilbeaux

swissre.com

According to the latest sigma study, global insured losses from natural catastrophes and man-made disasters were USD 45 billion in 2013, down from USD 81 billion in 2012. Of the 2013 insured losses, USD 37 billion were generated by natural catastrophes, with hail in Europe and floods in many regions being the main drivers.

Exxon to Disclose Extent of Its Carbon Asset Exposure

Tue, 2014-03-25 18:18 — Kathy Gilbeaux

newscientist.com - by Andy Coghlan - March 25, 2014

Oil giant Exxon Mobil has promised to reveal how much of its fossil fuel reserves could become worthless if governments agree to cut greenhouse gas emissions. It is the first major fossil fuel company to declare the size of its exposure to the so-called carbon bubble – the over-valuation of fossil fuel companies that could result if their assets are left unused.

To save ourselves from the worst impacts of global warming, we have to leave fossil fuels in the ground instead of burning them.

“Temperatures have been flat for 15 years—nobody can properly explain it,” the Wall Street Journal says. “Global warming ‘pause’ may last for 20 more years, and Arctic sea ice has already started to recover,” the Daily Mail says. Such reassuring claims about climate abound in the popular media, but they are misleading at best. Global warming continues unabated, and it remains an urgent problem.

What We Know: The Reality, Risks and Response to Climate Change

Sat, 2014-03-22 22:52 — Kathy Gilbeaux

whatweknow.aaas.org

The overwhelming evidence of human-caused climate change documents both current impacts with significant costs and extraordinary future risks to society and natural systems. The scientific community has convened conferences, published reports, spoken out at forums and proclaimed, through statements by virtually every national scientific academy and relevant major scientific organization — including the American Association for the Advancement of Science (AAAS) — that climate change puts the well-being of people of all nations at risk.

Surveys show that many Americans think climate change is still a topic of significant scientific disagreement.i Thus, it is important and increasingly urgent for the public to know there is now a high degree of agreement among climate scientists that human-caused climate change is real. Moreover, while the public is becoming aware that climate change is increasing the likelihood of certain local disasters, many people do not yet understand that there is a small, but real chance of abrupt, unpredictable and potentially irreversible changes with highly damaging impacts on people in the United States and around the world.

Abrupt Climate Change: No Bioperturbation

Thu, 2014-03-20 18:00 — Kathy Gilbeaux

National Academy of Sciences (NAS)

truth-out.org - by Bruce Melton - March 18, 2014

Today, we are burning fossil carbon one million times faster than it was naturally put in the ground, and carbon dioxide is increasing 14,000 times faster than anytime in the last 610,000 years (1,2). Climate is now changing faster than it has during any other time in 65 million years - 100 times faster than the Paleocene/Eocene extinction event 56 million years ago see here.(3) However, "climate change" is not the most critical issue facing society today; abrupt climate change is.
