Two stories I came across yesterday struck me as particularly indicative of the gulf between the speed at which global change is unfolding and our perceptions of the urgency of the issues. There's often a presumption that we have decades to change (so change can begin gradually) and decades more before we have to worry about impacts. The evidence, though, increasingly points to a much shorter horizon for action and adaptation.

The first story reports on a big Stanford study which combined the latest suite of climate models to understand how climate change already under way is likely to affect the hottest extremes of weather in the Western U.S.:

"The results were surprising. According to the climate models, an intense heat wave -- equal to the longest on record from 1951 to 1999 -- is likely to occur as many as five times between 2020 and 2029 over areas of the western and central United States. ...

The Stanford team also forecast a dramatic spike in extreme seasonal temperatures during the current decade. Temperatures equaling the hottest season on record from 1951 to 1999 could occur four times between now and 2019 over much of the U.S., according to the researchers.

The 2020s and 2030s could be even hotter, particularly in the American West. From 2030 to 2039, most areas of Utah, Colorado, Arizona and New Mexico could endure at least seven seasons equally as intense as the hottest season ever recorded between 1951 and 1999, the researchers concluded.

"Frankly, I was expecting that we'd see large temperature increases later this century with higher greenhouse gas levels and global warming," Diffenbaugh said. "I did not expect to see anything this large within the next three decades. This was definitely a surprise."

The second story told of a new report from the venerable insurance company Lloyd's of London and the Royal Institute of International Affairs (often called Chatham House) finding that Peak Oil, rising global demand for energy and the need for emissions reductions (not to mention the vulnerability of energy infrastructure to climate change and political turmoil) are very likely to bring big shifts in energy prices in the relatively short term:

The review is groundbreaking because it comes from the heart of the City and contains the kind of dire warnings that are more associated with environmental groups or others accused by critics of resorting to hype. It takes a pot shot at the International Energy Agency which has been under fire for apparently under-estimating the threats, noting: "IEA expectations [on crude output] over the last decade have generally gone unmet."

The report the world is heading for a global oil supply crunch and high prices owing to insufficient investment in oil production plus a rebound in global demand following recession. It repeats warning from Professor Paul Stevens, a former economist from Dundee University, at an earlier Chatham House conference that lack of oil by 2013 could force the price of crude above $200 (£130) a barrel.

Both of these studies bear further examination and debate, of course, but the overall trend which I see them contributing to has become increasingly clear: a growing chorus of those tasked most explicitly with responsibility for our future -- doctors, generals, diplomats, scientists -- all telling us that when it comes to planetary crisis, the future is now.

Contrast that urgency with the political debate in most countries. What we see is an appalling gap between our elected leaders' perception that these are problems for future generations to solve and the reality that we're already dealing with them today.

There's a quote that's been bouncing around the Worldchanging office recently: "When there’s a gap between perception and reality, more reality won’t close the gap." The gap between the political perception of our problems being slow and distant and the reality of acceleration and imminence points again at the importance of stories that help change our perspectives on scope, scale and speed.
