In March 2007, we blogged about the dire situation of the South Pacific islands Kiribati and Tuvalu. The sea is rising due to global warming, and two uninhabited islands nearby have already sunk. Now Kiribati is preparing for extinction:

The leader of the South Pacific island nation of Kiribati laid out an extraordinary plan Monday (Sept. 22) that would scatter his people through the nations of the world as rising sea levels submerge the islands they have called home for centuries.

Rising sea levels are submerging the land. Land not yet submerged is being rendered uninhabitable by salty ground water.

What has the federal government done over the last eight years to stop global warming? Sadly, not much, despite numerous, dire warnings. Our new interactive timeline gives an at-a-glance overview of the scientific reports, lost policy opportunities, and environmental impacts over the last eight years. Click the forward and backward arrows to move through time, and click on a color-coded event box to learn more about it.

Besides giving a succinct summary of the last eight years, the timeline is fun to click around - lots of interesting information all in one place. And it makes it very clear what we need to do when the new administration comes in. There's no time to waste.

What if, instead of reducing the greenhouse gas concentrations that hold excess heat in our atmosphere, we injected something in the atmosphere to reflect sunlight back into space? That's the idea behind sulfate geo-engineering. As Bill wrote in his post "Can we engineer our way out?", there are a plethora of problems with geo-engineering, but scientists still study it as an option of last resort.

The idea of injecting sulfates into the atmosphere is based on the observation that large volcanic eruptions can cause short-term global cooling. But in addition to the usual problems with geo-engineering (for example, it does nothing to stop ocean acidification from excess CO₂), scientists have found a new one. Sulfate geo-engineering could endanger food and water supplies for billions of people in Africa and Asia, according to a recent paper in the Journal of Geophysical Research [PDF].

We frequently mention the IPCC reports on Climate 411 - often referencing them as the most trustworthy authority on global warming science. In fact, our very first blog post was titled "What is the IPCC, anyway?" But for non-scientists, these rather technical reports are a challenge to read.

Climate scientists Michael Mann and Lee Kump published the book Dire Predictions to make the IPCC's crucially important findings accessible to the layperson. For the most part, they succeed admirably. Mann and Kump did a remarkable job of simplifying complex ideas. But it still gets a little dense in places.

This Sunday's New York Times Magazine had a cover story on green investment titled "Capitalism to the Rescue". We've mentioned in other posts that venture capital investment in clean energy is on the rise. This article was interesting in that it profiled one particular venture capital firm, Kleiner Perkins. The author interviewed the firm's partners about why they see clean energy as such a good investment.

To start with, explained partner Randy Komisar, the current energy market is so large and outdated that "green-tech" is a huge and relatively low-risk opportunity. And we're not, as many think, waiting for the new inventions to come. We're waiting for federal policy to give private investment incentive. That is, we're waiting for a mandatory carbon cap.

This Stephen Colbert clip on oil companies and the environment is fall-over funny and dead-on right.

This post is by Sheryl Canter, an online writer and editorial manager at Environmental Defense Fund.

New York Times columnist Thomas Friedman, three-time winner of the Pulitzer Prize, has completed his transformation from Middle East specialist to green energy expert. He wants the United States to similarly switch focus.

Hot, Flat, and Crowded, Friedman's latest book, explains how and why we must stop relying on "fuels from hell" (coal, oil, and gas) as our primary source of energy, and instead switch to "fuels from heaven" (wind, water, and solar). Without this shift, he argues, not only will we cook the planet, but wreck the economy and destroy our way of life. It is tough to quibble with Friedman's assessments.

Last week, the New York Times Dot Earth blog posted a sobering video of coastline erosion in Alaska. This is no simulation - it's a time-lapse video made from pictures taken two hours apart from late June to late July of this year.

Last Thursday, the Global Carbon Project released its annual report on the state of the carbon cycle, Carbon Budget 2007 [PDF]. It emphasizes (as we reported earlier this year) that CO₂ levels are continuing upward, and the rate of increase is accelerating.

One reason for the acceleration in CO₂ concentrations is higher fossil fuel emissions. Despite rising fuel prices, global CO₂ emissions from fossil fuels rose 3 percent in 2007. That's just slightly below the average increase of 3.5 percent per year since 2000.

Today we're launching a resource for people who want to enter the green job market. Our new Green Jobs Guidebook is a first of its kind, addressing everything from where to get training, to where to find good-paying jobs that help the environment. The guide focuses on California, but much of the information is applicable anywhere in the country.

I co-authored the guide with California Green Jobs Associate Amy Pasciucco. Together we painstakingly researched green employment opportunities and expected salaries, compiled growth projections, and identified the experience and education levels required by employers.

And we didn't stop there.
