We Are Now in a Crucial Moment — It’s Time to Make a Decision

Al Gore

HuffPo- Posted: December 7, 2009 03:49 PM

Editor’s note: This guest post was written by former Vice President Al Gore for the Hopenhagen movement.

The world has arrived at a moment of decision.

As long as we continue to depend on dirty fossil fuels like coal and oil to meet our energy needs, and dump 90 million tons of global warming pollution into the atmosphere, we move closer and closer to several dangerous tipping points—points which scientists have repeatedly warned would, if crossed, threaten to make it impossible for us to avoid irretrievable destruction of the conditions that make human civilization possible on this planet.

I’ve said it numerous times already, but right now we are trapped in a dangerous cycle—borrowing money from China to buy oil from the Persian Gulf, and then burn it in ways that destroy the planet. Every bit of that’s got to change.

Right now, here in the US and all over the world, people are demanding action. There is a much broader consensus than there was when President George H.W. Bush negotiated—and the Senate ratified—the Framework Convention on Climate Change in 1992. And there’s much stronger consensus than when we completed the Kyoto Protocol in 1997.

The road to the signing of an agreement in Copenhagen will not be easy, but the world has traveled this path before. More than twenty years ago the US signed the Montreal Protocol, a treaty to protect the ozone layer, and strengthened it to the point where we banned most of the major pollutants that created the hole in the ozone over Antarctica. And we did it with bipartisan support: President Ronald Reagan and Speaker of the House Tip O’Neill joined hands to lead the way.

We can do it again and solve the climate crisis, protecting our planet for future generations.

A new peer-reviewed climate study is presenting a head on challenge to man-made global warming claims. The study by three climate researchers appears in the July 23, 2009 edition of Journal of Geophysical Research. (Link to Abstract)

Full Press Release and Abstract to Study:

July 23, 2009

Three Australasian researchers have shown that natural forces are the dominant influence on climate, in a study just published in the highly-regarded Journal of Geophysical Research. According to this study little or none of the late 20th century global warming and cooling can be attributed to human activity.

The research, by Chris de Freitas, a climate scientist at the University of Auckland in New Zealand, John McLean (Melbourne) and Bob Carter (James Cook University), finds that the El Niño-Southern Oscillation (ENSO) is a key indicator of global atmospheric temperatures seven months later. As an additional influence, intermittent volcanic activity injects cooling aerosols into the atmosphere and produces significant cooling.

“The surge in global temperatures since 1977 can be attributed to a 1976 climate shift in the Pacific Ocean that made warming El Niño conditions more likely than they were over the previous 30 years and cooling La Niña conditions less likely” says corresponding author de Freitas.

“We have shown that internal global climate-system variability accounts for at least 80% of the observed global climate variation over the past half-century. It may even be more if the period of influence of major volcanoes can be more clearly identified and the corresponding data excluded from the analysis.”

Bill McKibben: Why I’m Planning to Get Arrested on Monday (and You Should, Too)

By Bill McKibben, Yale Environment 360. Posted February 24, 2009.

With thousands of big names and small gathering, the first massive protest of its kind against global warming will put the heat on DC.

It may seem odd timing that many of us are heading to the nation’s capital early next month for a major act of civil disobedience at a coal-fired power plant, the first big protest of its kind against global warming in this country.

After all, Barack Obama’s in power. He’s appointed scientific advisers who actually believe in… science, and he’s done more in a few weeks to deal with climate change than all the presidents of the last 20 years combined. Stalwarts like John Kerry, Henry Waxman, and Ed Markey are chairing the relevant congressional committees. The auto companies, humbled, are promising to build rational vehicles if only we give them some cash. What’s to protest? Why not just give the good guys a break?

If you think about it a little longer, though, you realize this is just the moment to up the ante. For one thing, it would have done no good in the past: you think Dick Cheney was going to pay attention?

More importantly, we need a powerful and active movement not to force the administration and the Democrats in Congress to do something they don’t want to, but to give them the political space they need to act on their convictions. Barack Obama was a community organizer — he understands that major change only comes when it’s demanded, when there’s some force noisy enough to drown out the eternal hum of business as usual, of vested interest, of inertia.

Consider what has to happen if we’re going to deal with global warming in a real way. NASA climate scientist James Hansen — who has announced he plans to join us and get arrested for trespassing in the action we’re planning for March 2 — has demonstrated two things in recent papers. One, that any concentration of carbon dioxide greater than 350 parts per million in the atmosphere is not compatible with the “planet on which civilization developed and to which life on earth is adapted.” And two, that the world as a whole must stop burning coal by 2030 — and the developed world well before that — if we are to have any hope of ever getting the planet back down below that 350 number.

Dangerous Sea Level Rise Imminent Without Large Reductions of Black Carbon

News Blaze- Published: December 12,2008

The world is already close to passing the tipping points for abrupt climate change events, and if strong measures aren’t taken immediately the results will be catastrophic, concluded panelists during a side event at the UN climate conference in Poznan Tuesday night. Both scientific experts and government representatives alike at the event sponsored by the Federated States of Micronesia and Sweden, stressed the urgent need for fast-action mitigation measures that should be implemented and expanded immediately in order to avoid devastating consequences such as sea level rise.

Dr. Hermann Held of the Potsdam Institute for Climate Impact Research pointed out that land ice melt is being vastly underestimated, and that non-linear abrupt climate change is not being taken into account as it should be by the climate convention. The world is already committed to an astounding 2.4 degrees of warming, due in part to the warming effects of black carbon – a substance that is now considered the second-greatest contributor to climate change after CO2 – which are being “unmasked” by reductions of SO2, which produces a cooling effect.

Environmental Progress Is a Cause for Right-Wing Paranoia

By Janet Smith, Intelligence Report. Posted December 12, 2008

Some conservatives have the wild notion that environmental policies are out to destroy American’s freedoms.

Addison, Texas — “Environment is not about saving nature,” the founder of Freedom Advocates, Michael Shaw, sternly warned an audience of antigovernment “Patriots” and far-right conspiracy theorists during a mid-July conference. “It’s about a revolutionary coup in America. [Environmentalism] is to establish global governance and abandon the principles of Natural Law.” Sustainable development policies, Shaw argued, will require “a police state” and ultimately “turn America into a globally governed homeland where humans are treated as biological resources.”
Shaw’s fearful call to arms against environmentalism was sucked in whole hog during the Ninth Annual Freedom 21 conference held in a Dallas-area Crowne Plaza hotel. Co-hosted by the Texas Eagle Forum, a hard-line Christian Right organization, and the anti-“New World Order” American Policy Center (APC), the three-day convergence included such right-wing heavyweights as the error-prone conspiracy theorist Jerome Corsi, gay- and feminist-hating Phyllis Schlafly, and the far-right Constitution Party’s presidential candidate, Chuck Baldwin.
