When we first launched the Climate 411 blog, we posted a lot of useful articles on the basic science of climate change. I often want to link to them in other posts, but I have trouble finding them. If I have trouble finding them, you all certainly must, so here are the links, all in one place.

Sequestering Carbon in Soil and Trees

By Martha Roberts / Published: December 18, 2007

Martha RobertsThis post is by Martha Roberts, an economist at Environmental Defense. It’s the first of a three-part series on carbon sequestration – storing carbon or carbon dioxide (CO2) in soils, trees, geological formations, and oceans.

1. Biological Sequestration
2. Geological Sequestration
3. Ocean Sequestration

Global warming is occurring because – day after day, hour after hour – human activities pump large amounts of greenhouse gases into the atmosphere. One way to decrease emissions is to store carbon or CO2 someplace other than the atmosphere.

There are two vastly different ways of sequestering carbon: biological and geological. The topic of this post is biological sequestration, which is among the biggest of the "low hanging fruits" for making quick, substantial cuts in emissions.

The Global Warming in the Pipeline

By Lisa Moore / Published: November 20, 2007

This post is by Lisa Moore, Ph.D., a scientist in the Climate and Air program at Environmental Defense.

A common refrain here on Climate411 is that we need to cut greenhouse gas emissions as soon as possible. One of the reasons we’ve cited numerous times is that, even if we could stabilize greenhouse gas concentrations at today’s levels, some global temperature increase is already locked into the system. This is sometimes called the “warming commitment” or the “warming in the pipeline”.

What’s behind this phenomenon? The short answer is: water, water everywhere.

Extinctions Increase with Global Warming

By Lisa Moore / Published: November 12, 2007

This post is by Lisa Moore, Ph.D., a scientist in the Climate and Air program at Environmental Defense.

Earth is home to millions of species. This rich biodiversity isn’t just beautiful, it’s also tremendously valuable. As just one example, consider coral reefs. They support fisheries that are the main source of protein for a billion people, and bring billions of tourist dollars into local economies.

Scientists have warned that climate change puts a large fraction of Earth’s species at risk for extinction. Most of these predictions are based on comparisons between species’ apparent climate requirements to projections of future conditions. A new study [PDF] in the Proceedings of the Royal Society B looks at the relationship between climate and biodiversity from a different perspective: the Earth’s deep past. The study found a long-term correlation between global temperature and extinction.

How Global Warming Stokes Wildfires

By James Wang / Published: October 31, 2007

This post is by James Wang, Ph.D., a climate scientist at Environmental Defense.

The wildfires in California prompted the largest mass evacuation in California history, destroying half a million acres and over 1500 homes. People are saying that global warming may have played a part in the severity of the blazes. But where is the connection? And how can global warming cause both floods and droughts?

Floods Devastate Asia and Africa

By Sheryl Canter / Published: October 16, 2007

The author of today’s post is Sheryl Canter, an Online Writer and Editorial Manager at Environmental Defense.

It’s been raining a lot in some parts of the world. In Northern India, Bangladesh, and Nepal, the worst rains in decades have devastated tea and rice crops, killed at least 3000 to 4000 people, and affected tens of millions of people since June. Great tracts of land are under water. Crop land has been destroyed; people are hungry. And the weather forecast says rain.

Torrential rains also have caused severe flooding in Korea, Uganda, and Sudan. In North Korea, over 600 people are dead or missing, 170,000 people displaced, and almost 1 million people affected. In Sudan, 200,000 are homeless from floods. India, itself reeling, sent $250,000 in aid to flood-ravaged Uganda.

Is this all from global warming?
