Climate experts are downplaying the science to avoid despair and inaction

Global warming is exaggerated and is just hyped by climate scientists. It’s not a big deal. That is what you might think if you listen to the mainstream media and its misinformation, or if you believe in the denier’s lies and their anti-science rhetoric about man-made climate change.

But that is so far from the truth that it’s absurd as a recent poll among climate experts and scientists clearly show. The poll conducted by the Guardian during the scientific conference in Copenhagen earlier this year shows that 9 out of 10 climate experts don’t believe we will be able to restrict climate change to 2C:

“Almost nine out of 10 climate scientists do not believe political efforts to restrict global warming to 2C will succeed, a Guardian poll reveals today. An average rise of 4-5C by the end of this century is more likely, they say, given soaring carbon emissions and political constraints.

Such a change would disrupt food and water supplies, exterminate thousands of species of plants and animals and trigger massive sea level rises that would swamp the homes of hundreds of millions of people.

The poll of those who follow global warming most closely exposes a widening gulf between political rhetoric and scientific opinions on climate change. While policymakers and campaigners focus on the 2C target, 86% of the experts told the survey they did not think it would be achieved. A continued focus on an unrealistic 2C rise, which the EU defines as dangerous, could even undermine essential efforts to adapt to inevitable higher temperature rises in the coming decades, they warned.”

The poll shows that climate experts are not exaggerating the effects of global warming but that they are actually downplaying and toning down their research in an attempt to avoid despair and inaction among the public.

Gore: We cannot negotiate with the facts, the truth and the consequences

By Simon Leufstedt on January 7th, 2009

During the embarrassing UN Climate Change Conference in Poznań, Poland, Al Gore held a speech where he said that the old and now “inadequate” climate change targets of 450 ppm (parts per million of CO2) had been made obsolete by new science (That’s what we and others have been saying for a while now). Gore said that the world should instead aim for a 350 ppm target.

The full transcript of his speech can be found below:

Orwellian Australian “Carbon Pollution Reduction Scheme” will DOUBLE Greenhouse Gas Pollution by 2050

By Dr Gideon Polya on August 5th, 2008

Only a few weeks after the release of the Draft Report of the seriously flawed, pro-coal, Australian Garnaut Climate Change Review (4 July, 2008; see my critique on Green Blog, “Pro-Coal, Australian Garnaut Climate Review Damns Coral, Australia & World”), the Australian Federal Government has released a so-called “Carbon Pollution Reduction Scheme” Green Paper (16 July, 2008).

Unfortunately the Australian Federal Government Carbon Pollution Reduction Scheme (CPRS) Green Paper is FATALLY FLAWED and if adopted globally would be a DEATH SENTENCE for the planet’s biosphere.

Australia is referred to as “Downunder” by people in the Northern Hemisphere but in so many things Australian mainstream media and politicians turn the truth upside-down as well – and this is outrageously so in relation to man-made climate change. The Liberal-National Party Coalition State and Federal Oppositions and the Labor Party State and Federal Governments (these major parties being referred to collectively as the Lib-Labs) pay public lip-service to the problem of global warming but their de facto policies support Australia’s world-leading coal exports and Australia’s 92% fossil fuel-based power generation.

Dr James Hansen says we should prosecute climate change liars

By Simon Leufstedt on June 25th, 2008

Dr James HansenDr James Hansen, director of the NASA Goddard Institute for Space Studies in New York and one of the worlds most prominent climate scientist, says in an article on the WorldWatch Institute website that climate change liars “should be tried for high crimes against humanity and nature.”

“Instead of moving heavily into renewable energies, fossil fuel companies choose to spread doubt about global warming, just as tobacco companies discredited the link between smoking and cancer. Methods are sophisticated, including funding to help shape school textbook discussions of global warming.”

“Remember this number for the rest of your life.”

By Simon Leufstedt on June 24th, 2008

The world is starting to realise that the goal of 450 ppm as a reasonable level to balance and stabilize the CO2 in our atmosphere is based on wrong and outdated science and won’t be enough to stop man-made climate change.

More and more scientific reports show that the older science has been too “soft” in their climate change calculations. For example, we can already now see a never ending and rapid melting of the Arctic ice, something that “would happen in 20-30 years” according to the older science reports. Scientific reports earlier projected that the Arctic would become ice-free by year 2050. But newly released reports suggest it could happen as early as 2013.
