Climate researchers said Thursday the planet could warm by more than 3.5 degrees Celsius, boosting the risk of drought, flood and rising seas. The UN's target is a 2 C limit on warming from pre-industrial levels for manageable climate change. In a report, scientists said Earth's average global temperature rise could exceed the dangerous 3.5 C warming they had flagged only six months ago.

At the Camp David meeting last week, G8 leaders agreed to act on climate change and air pollution by focusing on methane, black carbon (soot), and hydroflurocarbons (HFCs).

This is the logical follow up of a move in the same direction by the United States, China and other countries back to February. However, like the previous agreement, CO2 is still not mentioned.

The aforementioned greenhouse gases are much more potent but remain for much less time in the atmosphere than carbon dioxide

RESIDENTS of areas hit by natural disasters such as cyclones and storms could face carbon tax bills for the greenhouse emissions arising from rubbish created by the disaster, a Senate estimates hearing was told yesterday.

The revelation came as the government released a list of 104 local councils it believes may have to pay the tax because of the carbon emissions from rubbish dumps, 46 of which are in NSW and 21 in Victoria.

Scientists have identified thousands of sites in the Arctic where methane that has been stored for many millennia is bubbling into the atmosphere.
The methane has been trapped by ice, but is able to escape as the ice melts.
Writing in the journal Nature Geoscience, the researchers say this ancient gas could have a significant impact on climate change.
Methane is the second most important greenhouse gas after CO2 and levels are rising after a few years of stability.

In response to demands from companies engaged in extracting coal bed methane (CBM) for a single operator who would work the CBM blocks, an inter-ministerial panel has asked the petroleum secretary GC Chaturvedi to prepare a note on best practices for the sector in areas where oil and gas finds overlap.

A federal proposal to ban the construction of coal-fired power plants that release all of their carbon dioxide into the atmosphere would seem to smooth the way for carbon capture, a budding technology that traps the greenhouse gas for storage or other uses.

But even as the Environmental Protection Agency prepares to open hearings on the proposed rule, unveiled in March, industry experts say the persistently low price of natural gas is threatening the viability of the nation’s carbon capture projects.

California on Wednesday released an updated draft of its cap-and-trade regulations that for the first time includes language that would link its carbon market to a similar scheme in the Canadian province of Quebec.

The draft language called for the mutual acceptance of compliance instruments like allowances and offset credits between the two jurisdictions.

It also called for a common allowance registry and auction, and included provisions for tracking allowances which are designed to enhance market security.
