Europe Pledges Over $10 Billion for Climate Change Adaptation in Developing Nations

The European Union hopes the deal can boost chances of further international agreement at the UN's climate summit

A lot of the climate change debate may focus on how to cut carbon dioxide emissions to prevent global temperature rise, but many nations are already struggling with the consequences of local climate change--rising sea levels, water shortages and agricultural problems. Now the European Union has promised over $10 billion over the next three years for a "fast start" fund to help the poorest nations adapt to climate change.

EPA Officially Declares Greenhouse Gases a Danger as Copenhagen Conference Begins

The U.S. signals its readiness to regulate carbon dioxide emissions; world leaders begin Copenhagen discussions on climate change

Today's symbolic but politically crucial move by the Environmental Protection Agency (EPA) recognizes greenhouse gases as a danger for humans and Earth alike. That would open the doors for new regulations on carbon dioxide emissions from vehicles, power plants and factories, according to the New York Times.

MIT Redesigns Natural Gas Power Plant For Near-Zero Carbon Emissions

New technology produces energy from fuel without burning it

With the conference in Copenhagen swiftly approaching, and the Senate analog to the Waxman-Markey "American Clean Energy and Security Act" struggling towards the floor, little doubt remains that fossil fuel-burning power plants will soon face either fines for, or mandatory reduction of, carbon emissions. Luckily, a team at MIT has devised a power plant set up that generates power from fossil fuels, but does so with almost none of the carbon emissions.

Study Finds Ozone Hole Repair Contributes To Global Warming, Sea Ice Melt

The 20th century's biggest environmental success may exacerbate the 21st century's biggest environmental crisis

In 1985, scientists from the British Antarctic Survey found a giant hole in the ozone layer of Earth's atmosphere over the South Pole. This discovery prompted a largely successful international effort to ban CFCs, the chemicals largely responsible for man-made thinning of the ozone layer.

Ocean Ecosystem Guide Released by CSIRO

The Marine Climate Change Impacts and Adaptation Report Card for Australia, and an accompanying website, will provide a biennial guide for scientists, government and the community on observed and projected impacts of climate change on marine ecosystems.

"The objective of compiling this information is to consider options available to environmental and resource managers in their response to changes in ecosystem balance," says project leader, CSIRO Climate Adaptation Flagship scientist Dr Elvira Poloczanska.

Study reveals flaws in climate change research

A new study by University of Newcastle researchers is questioning widespread claims that the drought experienced in Australia's Murray Darling Basin is a result of CO2 emissions. The analysis, to be published in the journal Geophysical Research Letters, concluded that the cause of elevated temperatures in the Murray Darling Basin was a combination of natural factors.

WWF: We Have Until 2014 To Stop Global Warming

It’s no secret that the world is warming, but a new report published by the World Wildlife Fund suggests we may not have as much time to mull solutions as we think. If the world doesn’t commit to green technologies by 2014, the report says, runaway global warming and economic meltdown are all but unstoppable.

Largest Carbon Sequestration Plant To Pump 3.3 Million Tons Of CO2 Into Ground

Even before a single ounce of natural gas gets burned in a home or power plant, massive amounts of CO2 have already been released. The process of extracting natural gas releases carbon dioxide pent up in the same wells as the gas, thus adding to the climate-changing impact of the fuel.

To help lower the global warming impact of one of the world's largest natural gas fields, General Electric has supplied Chevron, Exxon Mobile and Shell with enough compression "trains"--the pumps and turbines that do the sequestering--to create the world's largest carbon sequestration project. The trains will pump 3.3 million tons of CO2 released from natural gas mining back into the ground every year. That's the equivalent of taking 630,000 cars off the road.

Comparing and Graphing Nine Environmental Threats, Researchers Find Unexpected Evils

Publishing in the journal Nature, a group of 29 scientists have established a comparative scale for rating the immediate threat posed by nine environmental hazards--everything from climate change to ocean acidification. And while our warming climate gets most of the attention, more immediate problems may be brewing in our intensifying lack of biodiversity and out-of-whack nitrogen cycle.

At UN Climate Change Conference, US And China Promise Carbon Emission Reductions

Today, heads of state from around the globe met at the United Nations to face a problem that affects all of their constituencies: climate change. In a day-long conference on global warming, President Obama lamented that the United States was slow to recognize and respond to the problem of global warming, and vowed to move swiftly to counter it. President Hu Jintao of China echoed those statements, listing a four-point plan to combat carbon emissions.

Geoengineering: Visions of Fake Plastic Trees and Algae Tanks on Every Roof

Could cutting carbon emissions give way to carbon-capturing artificial trees and rooftop slime?

Geoengineering is a popular idea, for Bill Gates and just about everyone else these days. Now the Institute of Mechanical Engineers proposes that the UK adopt technologies such as carbon-capturing artificial trees, biofuel algae tanks on rooftops, and coating surfaces in reflective materials to cut down on heating from the sun's rays.

U.S. Chamber of Commerce Seeks To Sue EPA Over Global Warming

In an attempt to head off new emissions standards, the U.S. Chamber of Commerce is threatening to sue the Environmental Protection Agency. The Chamber is calling it the Scopes Monkey Trial of the 21st Century, and wants to put the evidence supporting global warming on trial in a court of law.

Warming Oceans May Cause the Earth to Tilt

Global warming and expanding oceans, beyond immediate effects on the surface of our planet, may even cause the earth's axis to shift

Human activity has widely affected our planet, reshaping surfaces, moving or extinguishing species, and warming the air and water. Now scientists say our reach has been extended even further -- warming oceans may even start to shift the Earth's axis of rotation.
