A Holiday Gift from Climate Scientist James Hansen
For new inspiration and knowledge, we would most like to recognise James Hansen, who with the publication of his book Storms of My Grandchildren has made climate science accessible and interesting to anyone with a high school education.
Climate Betrayal in Copenhagen – GPC-PVC
“The political statement agreed to with much fanfare in Copenhagen at the 15th Conference of the Parties is not what was needed,” says Elizabeth May, the Green Party of Canada Leader. “With clear warnings from science that greenhouse gas emissions must halt their global rise and begin a steep decline no later than 2015, the leaders gathered in Copenhagen have issued a compromise statement that should never have been written.”
The Physics of Copenhagen: Why Politics-As-Usual May Mean the End of Civilization
In Copenhagen, if the U.S. is willing to treat climate change as politics-as-usual, most of the other major players will simply follow suit. They’ll sign some kind of paper in Denmark — that became all but certain on Friday night when Obama announced he’d jet in for the meeting’s close. European leaders and some environmental groups may then call it a “qualified success,” and on we will go through more years of negotiation. In the meantime, physics will continue to operate, permafrost will continue to thaw, sea ice to melt, drought to spread. It’s like nothing we’ve ever faced before — and we’re facing it as if it’s just like everything else. That’s the problem.
56 newspapers around the world in 20 languages publish the same editorial calling for action from world leaders on climate change
Today 56 newspapers in 45 countries take the unprecedented step of speaking with one voice through a common editorial. We do so because humanity faces a profound emergency.
Unless we combine to take decisive action, climate change will ravage our planet, and with it our prosperity and security. The dangers have been becoming apparent for a generation. Now the facts have started to speak: 11 of the past 14 years have been the warmest on record, the Arctic ice-cap is melting and last year’s inflamed oil and food prices provide a foretaste of future havoc. In scientific journals the question is no longer whether humans are to blame, but how little time we have got left to limit the damage. Yet so far the world’s response has been feeble and half-hearted.
James Hansen says whole approach at Copenhagen is “so fundamentally wrong that it is better to reassess the situation”
In an interview with the Guardian, James Hansen, the world’s pre-eminent climate scientist, said any agreement likely to emerge from the negotiations would be so deeply flawed that it would be better to start again from scratch.
“I would rather it not happen if people accept that as being the right track because it’s a disaster track,” said Hansen, who heads the Nasa Goddard Institute for Space Studies in New York.
More Countries Recognizing the Importance of Stronger Targets at Copenhagen
It hasn’t made massive headlines in Europe; in fact it’s hardly been noticed. But over the last fortnight, three big countries have made major new pledges to cut their emissions of carbon dioxide from industry, transport and deforestation which is causing climate change.
Since 12 November, Russia, South Korea and Brazil have all announced new targets for cutting CO2, leading to a significant improvement in hopes for the outcome of the Copenhagen climate summit, which is now only two weeks away – and which, it was announced yesterday, at least 65 world leaders will attend.
Tipping Point, After Tipping Point…
Another disturbing milestone was passed on November 6. The graph below shows that although extent of the Arctic sea ice this past summer was greater than that of 2007, it is now less, a record low for its date. Ice covered the Arctic Ocean in a smaller area on November 6, 2009 than in any other year on November 6 since observations began in 1979.
Australian Professor Writes of the Likelihood of Runaway Climate Change
Rather than decarbonising, the world is carbonising at an unprecedented rate, and it is doing so at precisely the time we know we have to stop it. 2.5 degrees Celsius is likely by the end of the century in spite of our childlike belief that climate change can be averted; the cost will prove incalculable.
The Link Strong Between Carbon Dioxide and Global Warming
The science is clear: global warming is happening faster than ever and humans are responsible. Global warming is caused by releasing what are called greenhouse gases into the atmosphere. The most common greenhouse gas is carbon dioxide
The Moral Choice between Mitigation or Adaptation to Dangerous Climate Change
The world won’t adapt and can’t adapt to dangerous climate change: the only adaptive response to a global shortage of food is starvation. Of the two strategies it is mitigation, not adaptation, which turns out to be the most feasible option, even if this stretches the concept of feasibility to the limits. As Dieter Helm points out, the action required today is unlikely but “not impossible. It is a matter ultimately of human well being and ethics.”
