Grim Outlook for Polar Bears

The author of today’s post, Lisa Moore, Ph.D., is a scientist in the Climate and Air program.

What's a polar bear, Mommy?A frame from an Environmental Defense ad campaign about the danger of unchecked global warming.

Most Polar Bears Gone by 2050“. You may have seen that headline in the news this week. The study behind this depressing conclusion could land polar bears on the list of threatened species under the Endangered Species Act.

Bjorn Lomborg's Fundamental Mistake

Today’s post is by Jon Anda, president of Environmental Markets Network. It’s a response to a column in Tuesday’s New York Times.

The column’s writer, John Tierney, goes along with Bjorn Lomborg, author of the book “Cool It”. Lomborg acknowledges that global warming is happening, but is against “hysteria and headlong spending on extravagant CO2-cutting programs.”

In the world of greenhouse gases, the devil is in the details. Climate policy is not about any specific scenario – like the one-foot sea level rise Lomborg wades us through – but the chance of a catastrophic outcome.

VT Court Rejects Automakers' Attempt to Continue Polluting

The author of today’s post, Jim Tripp, is General Counsel at Environmental Defense. Working with state agencies and other environmental groups, Tripp presented arguments in the Vermont trial this spring.

We won an important victory today. A federal judge in Vermont ruled against U.S. automakers’ attempt to block states from setting new rules limiting global warming pollution from automobiles. In his ruling, Judge William K. Sessions III said that the auto industry failed to prove that it could not safely meet the tailpipe standards.

A number of environmental groups joined the State of Vermont in defending the case, including us at Environmental Defense, the Conservation Law Foundation, the Sierra Club, the Natural Resources Defense Council, and the Vermont Public Interest Research Group.

So can Vermont now implement the tighter emissions requirements? Not quite yet.

Cool New Energy Technologies

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

We know we need energy to power, well, everything. And we know that if we continue to get our power mainly from fossil fuels we’re in big trouble. So where do we get it?

Most people have heard about solar power and wind power, but there are some other alternatives that may be new to you.

Farm Animals and Methane

This is Part 1 of a three-part series on Food and Farming.

1. Increased CO2 and Food Quality
2. Farm Animals and Methane
3. “Food Mile” Complexities

The authors of today’s post are Lisa Moore, Ph.D., a scientist in the Climate and Air program, and Tim Male, Ph.D., a senior ecologist in the Land, Water & Wildlife program.

For the second course in our food series, let’s start with some pie – specifically, Bill’s greenhouse gas pie showing the contribution of different greenhouses gases to global warming. The first chart shows that methane is the second largest contributor to global warming.

Globally, nearly half of that hefty methane slice comes from agriculture. What causes these emissions, and how can we reduce them?

Climate News: Creeping Shrubs and Record Heat

The author of today’s post, Lisa Moore, Ph.D., is a scientist in the Climate and Air program.

This week I came across several interesting articles related to climate, but two in particular caught my eye. In the first, scientists found that excess carbon dioxide (CO2) may be what’s leaving livestock with less food to eat. The other study explores the role of greenhouse gases on the record-breaking heat Americans experienced in 2006.
