Impervious surfaces

Include our brains. This report about Houston from last year outlines how unchecked development remains a priority in the famously un-zoned city, creating short-term economic gains for some while increasing flood risks for everyone:

The area’s history is punctuated by such major back-to-back storms, but many residents say they are becoming more frequent and severe, and scientists agree.

“More people die here than anywhere else from floods,” said Sam Brody, a Texas A&M University at Galveston researcher who specializes in natural hazards mitigation. “More property per capita is lost here. And the problem’s getting worse.”

Why?

Scientists, other experts and federal officials say Houston’s explosive growth is largely to blame. As millions have flocked to the metropolitan area in recent decades, local officials have largely snubbed stricter building regulations, allowing developers to pave over crucial acres of prairie land that once absorbed huge amounts of rainwater. That has led to an excess of floodwater during storms that chokes the city’s vast bayou network, drainage systems and two huge federally owned reservoirs, endangering many nearby homes — including Virginia Hammond’s.

We must learn to do better, but long-term thinking tends to challenge us more than anything.

Giant waves of pain

Climate change is disturbing the pattern of atmospheric flow around the globe, says the Potsdam Institute for Climate Impact Research (PIK):

“An important part of the global air motion in the mid-latitudes of the Earth normally takes the form of waves wandering around the planet, oscillating between the tropical and the Arctic regions. So when they swing up, these waves suck warm air from the tropics to Europe, Russia, or the US, and when they swing down, they do the same thing with cold air from the Arctic,” explains lead author Vladimir Petoukhov.

“What we found is that during several recent extreme weather events these planetary waves almost freeze in their tracks for weeks. So instead of bringing in cool air after having brought warm air in before, the heat just stays. In fact, we observe a strong amplification of the usually weak, slowly moving component of these waves,” says Petoukhov. Time is critical here: two or three days of 30 degrees Celsius are no problem, but twenty or more days lead to extreme heat stress. Since many ecosystems and cities are not adapted to this, prolonged hot periods can result in a high death toll, forest fires, and dramatic harvest losses.

I know I don’t like when my flow is disturbed; It’s tough out there for a planet.

Sorry, Ross. Check out these new images from NASA.

Earth, smaller

So delicate, so just there, how would you think of defending the tiny blue band of atmosphere holding everything in place?

Hmmm? Hint: not fancy tanks or helicopters>
