U.S.-hosted climateClimate is typically defined as the average weather (or more rigorously a statistical description of the average in terms of the mean and variability) over a period of time, usually 30 years. These quantities are most often surface variables such as temperature, precipitation, and wind. Climate ... talks with the world’s biggest greenhouse gasGreenhouse gas emissions cause dangerous anthropogenic climate change. Emissions include CO2, fluoridated gases, methane which are emitted by human activity such as deforestation and burning fossil fuels, and water vapour. polluters concluded on Tuesday with signs of progress but sizable differences as nations work toward a deal this year to fight global warming, writes Reuters.

The two-day meeting, convened by U.S. President Barack Obama, was meant to pave the way for international talks in Copenhagen in December to forge a follow-up agreement to the Kyoto Protocol, which limits climate-warming greenhouse emissionsEmissions of greenhouse gases, greenhouse gas precursors, and aerosols associated with human activities, including the burning of fossil fuels, deforestation, land-use changes, livestock, fertilisation, etc. (IPCC) and expires in 2012.

Participation in the Kyoto ProtocolThe Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC) was adopted in 1997 in Kyoto, Japan, at the Third Session of the Conference of the Parties (COP) to the UNFCCC. It contains legally binding commitments, in addition to those included in the UNFCCC. Countries ... - Source: Wikipedia

German Environment Minister Sigmar Gabriel said a lot had changed since the Bush process but he said greater commitments from industrialized nations, including the United States, would be necessary to seal a global deal.
“It was very clear that the Americans are moving a lot,” he told reporters during a break from the meeting. “Measured by what Europeans believe needs to be done to fight climate changeClimate change is a lasting change in weather patterns over long periods of time. It can be a natural phenomena and and has occurred on Earth even before people inhabited it. Quite different is a current situation that is also referred to as climate change, anthropogenic climate change, or ..., we’re still very far apart from each other.”

Obama’s goal is to cut U.S. emissions of carbon dioxideCarbon dioxide (CO2) is emitted in several ways. Naturally through the carbon cycle and through human activities like the burning of fossil fuels. These human activities have increased CO2 concentrations in the atmosphere since the beginning of the industrial revolution and these high ... and other greenhouse gases by roughly 15 percent by 2020, back to 1990 levels. Obama wants the United States to lead in the climate change fight, but U.S. officials have indicated they do not see a lot of room for maneuver on the 2020 goal.

“To speak of America taking over the leading role in climate change — as a European, one can confidently say that the United States are far away from that” Gabriel said. “Europe still has this leadership role, but we would happily share it with the Americans.”

The European Union has pledged to cut emissions 20 percent below 1990 levels by 2020 and says it would pursue a 30 percent cut if other industrialized nations follow suit.

The major economies represented at the meeting include Australia, Brazil, Britain, Canada, China, the European Union, France, Germany, India, Indonesia, Italy, Japan, Korea, Mexico, Russia, South Africa and the United States.
