Climate Code Red

Description: 

Climate policy is characterised by the habituation of low expectations and a culture of failure. There is an urgent need to understand global warming and the tipping points for dangerous impacts that we have already crossed as a sustainability emergency, that takes us beyond the politics of failure-inducing compromise. We are now in a race between climate tipping points and political tipping points.

This is a book and web site about the urgency of the situation regarding climate change. They use the phrase "Code Red" in the way that hospitals mean it, that the patient is in critical danger, that everybody should drop what they're doing and go to emergency stations, and that it's this critical.

Why is the world's biggest landfill in the Pacific Ocean?

The North Pacific Subtropical Gyre has become clogged with trash. Due to its lack of large fish and gentle breezes, fishermen and sailors rarely travel through the gyre. But the area is filled with something besides plankton: trash, millions of pounds of it, most of it plastic. There are two patches, the Western and Eastern Pacific Garbage Patches. The western patch is between Hawaii and Japan, while the eastern one is between Hawaii and California. The patches are connected by a thin 6,000-mile long current called the Subtropical Convergence Zone. Research flights showed that significant amounts of trash also accumulate in the Convergence Zone.

Plastic constitutes 90 percent of all trash floating in the world's oceans. The United Nations Environment Program estimated in 2006 that every square mile of ocean hosts 46,000 pieces of floating plastic.

The main problem with plastic is it doesn't biodegrade. The durability of plastic which makes it attractive to use in products is what makes it not biodegrade. Instead it photodegrades and becomes shards of plastic. The tiny plastic particles can be sucked up by filter feeders and damage their bodies, and in general the plastic enters the food chain of the ocean. The fish are harmed and since we humans consume lots of seafood it will eventually harm us as well.

Grim look at state's plant life (California, that is)

"If temperatures rise rapidly in California this century, up to two-thirds of the state's native plants might lose large swaths of suitable habitat, according to a new study. " ... this estimation comes from researchers at many universities who released maps showing effects on plant species from climate change. As the environment warms up it changes the conditions, and both plants and animals tend to have narrow ranges of environment conditions in which they will live. If a given plant's preferred temperature range is between 70-90 degrees F and the ambient temperatures are regularly above 100 degrees the plant is likely to die. Further the area which has the preferred temperature range will move, either uphill (higher elevations have cooler temperatures) or further north. An effect that's been observed is for plant and animal species to be found higher and higher up mountains, and that some species eventually can go no higher in elevation because there's no more mountain, meaning the species will completely die out.

"All hands on Deck"

"How it all Ends" is an astonishingly great video series studying the climate change debate. It was put together by a high school science teacher, a truly excellent high school science teacher, using the props he had available in his classroom. He comes to a very interesting proposition that sidesteps most of the climate change debate. It's an logicians method, actually Pascal's Wager, that sets of a decision grid to help answer really tough problems. In the climate change debate there are multiple points of view and the naysayers have been able to create enough doubt that the population is frozen in indecision. But using Pascal's Wager this high school science teacher is able to show a way round the indecision, namely to say a) there are a ton of credible scientists who have put their reputations on the line saying man-made-climate-change is a huge problem, and b) the consequences of inaction look to be horrifying.

Anyway the videos caught the attention of a book publisher and now he's expected to create a book out of the material.

"All hands on Deck" is a call for volunteers to help collect the book material ...
