You were taught in school that the rain forest is like the lungs of our planet.
It’s not that simple.

A Renaissance in Economics The American President Ronald Reagan once quipped, “The nine most terrifying words in the English language are, ‘I’m from the government and I’m here to help.’” I get the same shivers when someone introduces themselves as an economist.
Why You Won’t Be the Person You Expect to Be (NYT): "When we remember our past selves, they seem quite different. We know how much our personalities and tastes have changed over the years. But when we look ahead, somehow we expect ourselves to stay the same... They called this phenomenon the “end of history illusion,” in which people tend to “underestimate how much they will change in the future.”" (via exp.lore) [more inside]
In January, 16 scientists and/or engineers wrote an opinion piece in the WSJ. This is the response of one of the academics cited in their piece: William Nordhaus. According to the 16 scientists/engineers, Nordhaus recommended no action on climate change for 50 years. But he didn't. The opinion piece has generated controversy among climate scientists as well.
Right Wing astroturfing A non-scientific analysis of the patterns in forum board discussions on a variety of topics. The gist: discussions of issues in which there's money at stake (like climate change, public health and corporate tax avoidance) are often characterised by amazing levels of abuse and disruption by rightwing libertarians who are pro-corporate, anti-tax, anti-regulation. Discussions of issues in which there's little money at stake tend to be a lot more civilised than debates about issues where companies stand to lose or gain billions.
Most people have heard about how rising CO2 levels are resulting in a changing global climate. Fewer have heard about the other consequence of rising CO2 levels- when the CO2 is absorbed into the oceans, it disassociates into carbonic acid. This alters the pH of our world's oceans, and it's called "Ocean Acidification". This changing ocean chemistry has many important and devastating consequences. [more inside]
potholer54 is a youtuber who in his own words; I've been a journalist for 20 years, 14 years as a science correspondent. My degree is in geology, but while working for a science magazine and several science programs I had to tackle a number of different fields, from quantum physics to microbiology. He has a series called Climate Change that you might find interesting. [more inside]
Video (8MB, MPEG) of arctic sea ice extent, recorded from January to September 2007. [other formats] This summer a dramatic decrease compared to previous years in the extent of the north pole ice cap was observed. Scientists are freaked out [bugmenot]. This summer, the Northwest Passage was open for a few weeks, allowing three ships to traverse it. [more inside]
Who can you trust if you can't trust the Wall Street Journal? RealClimate debunks the latest junk science on climate change from the pages of the Wall Street Journal.
Scientists bewildered by sharp rise of CO2 in atmosphere for second year running. "The fear held by some scientists is that the greater than normal rises in C02 emissions mean that instead of decades to bring global warming under control we may have only a few years. At worst, the figures could be the first sign of the breakdown in the Earth's natural systems for absorbing the gas. That would herald the so-called "runaway greenhouse effect", where the planet's soaring temperature becomes impossible to contain. As the icecaps melt, less sunlight is refected back into space from ice and snow, and bare rocks begin to absorb more heat. This is already happening."
