Ice Loss Sends Alaskan Temperatures Soaring

This is a guest post by Alex Kirby originally published by Climate News Network.

If you doubt that parts of the planet really are warming, talk to residents of Barrow, the Alaskan town that is the most northerly settlement in the US.

In the last 34 years, the average October temperature in Barrow has risen by more than 7°C − an increase that, on its own, makes a mockery of international efforts to prevent global temperatures from rising more than 2°C above their pre-industrial levels.

A study by scientists at the University of Alaska Fairbanks analysed several decades of weather information. These show that temperature trends are closely linked to sea ice concentrations, which have been recorded since 1979, when accurate satellite measurements began.

The study, published in the Open Atmospheric Science Journal, traces what has happened to average annual and monthly temperatures in Barrow from 1979 to 2012.

In that period, the average annual temperature rose by 2.7C. But the November increase was far higher − more than six degrees. And October was the most striking of all, with the month’s average temperature 7.2C higher in 2012 than in 1979.

Commissioner’s Report Shows Canada Must Do More For Environment

David Nanuk

This is a guest post by David Suzuki.

Canadians expect to have our environment protected, and to know how it’s being protected. A report from Canada’s Commissioner of the Environment and Sustainable Development shows we’re being short-changed.

In many key areas that we looked at, it is not clear how the government intends to address the significant environmental challenges that future growth and development will likely bring about,” commissioner Julie Gelfand said of the report, which used government data, or lack thereof, to assess the government’s success or failure to implement its own regulations and policies.

Subsidy Spotlight: Paying the Price of Tar Sands Expansion

This is a guest post by Anna Simonton, on assignment with Oil Change International.

Carolyn Marsh was in her living room watching television on a Wednesday night in August when she heard a loud boom from somewhere outside. Having lived in the industrial town of Whiting, Indiana––just south of Chicago––for nearly three decades, she wasn’t terribly shaken. “There’s a lot of noise constantly,” she explains.

But when the news came on an hour later and reported an explosion at the nearby BP refinery, Marsh was incensed. It was the second serious incident since the recent completion of BP’s Whiting Refinery Modernization Project, which Marsh had fought to prevent.

In December 2013, after six years of community pushback, court battles, Environmental Protection Agency citations, and ongoing construction in spite of it all, BP’s $4.2 billion retrofitted facility came fully online.

Judith Curry is Back Advocating Climate Inaction in the Wall Street Journal

This is a guest post by Climate Nexus.

Judith Curry’s latest op-ed in the Wall Street Journal touts her new study co-authored with Nic Lewis. The takeaway of the piece - that the need for emissions reductions is “less urgent” than policymakers assume – is not even supported by her own study, much less the scientific mainstream. 

Curry provides a highly biased and skewed overview of climate sensitivity studies, which makes sense for publication in the Wall Street Journal. In reality, the IPCC sensitivity estimate remains the most reliable and comprehensive expression of the state of knowledge on the topic, and scientists agree that this sensitivity range implies an urgent need for climate action.

  • Curry’s study doesn’t reveal new information that would affect IPCC estimates.
  • She examines only a small group of studies that agree with her conclusion, while the IPCC took many additional methods and factors into account.
  • Even low climate sensitivities still carry an urgent need to reduce greenhouse gas pollution.
  • Curry has growing ties to denier groups and her consulting business serves fossil fuel companies.

GWPF Funder Lord Leach - Relying on Unreliable Global Warming Information

DeSmog UK has found that libertarian banker Lord Leach is a funder of the anti-climate political advocacy group the Global Warming Policy Foundation (GWPF). Lord Leach gave a long speech in Parliament detailing his beliefs about global warming, writes Dana Nuccitelli (pictured). 

The speech was full of inaccuracies, myths, and misinformation. Known as a Gish Gallop, the sheer number of false claims in the speech would require tremendous effort to debunk. Most telling were the sources that Lord Leach relied upon to support his statements. For example…

Let’s Slow Down, For The Sake Of Ourselves And Our Planet

This is a guest post by David Suzuki.

The Amazon rainforest is magnificent. Watching programs about it, we’re amazed by brilliant parrots and toucans, tapirs, anacondas and jaguars. But if you ever go there expecting to be overwhelmed by a dazzling blur of activity, you’ll be disappointed. The jungle has plenty of vegetation — hanging vines, enormous trees, bromeliads and more — and a cacophony of insects and frogs. But much of the activity goes on at night or high up in the canopy.

Films of tropical forests don’t accurately reflect the reality of the ecosystems. They’re skillfully edited shots acquired over many months. Our media-nurtured impatience and urgent sense of time often prevent us from seeing how life truly unfolds.

Nature needs time to adjust and adapt to biosphere changes. After life appeared on Earth, atmospheric oxygen gradually went from zero to 20 per cent, oceans appeared and disappeared, mountains thrust upward and then eroded, continents moved on tectonic plates, climate cycled between ice ages and warm intervals, magnetic poles reversed and re-reversed. Life flourished because species and ecosystems evolved over time.
