If you follow climate change news carefully, and I hope you do, you know that an important event looms. That would be the latest report from the Intergovernmental Panel on Climate Change (IPCC). The report is due in September. Though denialists have branded this organization as a club of worry-wart, alarmist exaggerators, the truth is that it is a consensus-bound body, which adheres to conservative protocols.
So it is fair to say that IPCC projections tend toward the low end of the effects of our uncontrolled experiment in atmosphere transformation. That said, let’s see what is on tap, based on some early releases of findings (shared by Chris Mooney of Mother Jones). Nothing much to worry about, folks. Substantial melting of the Greenland ice sheet, sea rise of five to ten meters, runaway ocean acidification. So what? This blog post by the Guardian’s John Abraham suggests that contrarians will have no choice but join the consensus and stop fighting policy to deal with the threat.
One thing is clear. The changes predicted by IPCC based on current trends are not some far-off theoretical possibility. They are happening right now. There of course is accelerating Arctic melting – clear for all to see. And there is that persistent drought in the American Southwest, dramatically lowering the flow on the Colorado River and showing the newly famous “bathtub ring” at Hoover Dam’s Lake Mead. Thirteen years and counting; bound to end any day now, eh? And let’s not forget the western fire season, now in full swing and threatening state budgets (and even the water supply of San Francisco). A less dramatic, though arguably more universal, phenomenon has overtaken weather patterns – “stuck weather.” Though this can mean weeks of beautiful weather, or a hellacious heat wave that just won’t quit, it all results from the same condition – a weak, meandering jet stream caused by a vastly warmer Arctic. We are currently switching gears right now in Minnesota from a warm, settled regime into a possible record heat wave (for this late summer season) – as Paul Douglas reports in his consistently excellent weather and climate blog.
So though climate change evidence becomes clearer every day, I remain skeptical about significant action in the near term, for two important reasons. The first is the fact that a well-funded, powerful, persistent campaign of pignorant (pretend-ignorant) anti-science has lulled a significant slice of the public into somnolence. Adam Frank – author of About Time – chronicles our pathetic decline into science denial in this fine column he wrote for the New York Times – summarized here and commented on by Tree Hugger’s Chris Tackett. (See a glimmer of hope there in the planned reboot of the TV series Cosmos.) The second is the pathetic power structure that has taken hold in modern America. With the GOP in the (gerrymandered) majority in the House of Representatives right now, this is the pignorant posse that passes for leadership of the House Science(!) Committee. It is so bad that I mainly agree with these two assessments of the cause and results of our spending decades dealing with denialists’ posturing rather than accepting the science and moving ahead. The first is by Jeff Schweitzer and the second by Robert Parry. Neither pulls punches in calling out the real engineers of today’s alarmingly science-dumb state of affairs among the public. I especially identify with Frank’s description of his earlier mistake in judgment – that public awareness and understanding of scientific reality would only grow. Sorry.
Surely, this state of affairs can’t go on indefinitely. And in fact a recent media shift may point to some hope from an unlikely source – the much-maligned (in some circles) Al Jazeera. Sure, the burst of coverage on the newly realigned network far surpasses typical American coverage because of the dismally low standard. But we need hope on waking up the public, and allies of all stripes are valuable. And of course this is a global problem, calling especially for leadership on the part of the wealthy industrialized nations. Here is a call for action on the part of the United Kingdom’s David Cameron. And despite continued intransigence on the part of the pignorant right in the United States, prominent activists see hope for action. In this interview, former Vice President Al Gore sees a tipping point in public opinion based largely on growing consensus on the connection between ever-wilder weather and our continued dumping of greenhouse gases into the atmosphere. Gore holds onto his optimism despite interviewer Ezra Klein’s tough questioning.
This is no time for giving in to complacency and inevitability. Active groups such as the Climate Reality Project and 350.org are doing no such thing. And the single most helpful step – maybe even more helpful than killing the Keystone XL pipeline – would be enacting a carbon fee system. That’s the goal of the Citizens Climate Lobby, endorsed by former NASA scientist James Hansen.
