Using projected boundary conditions for the end of the twenty-first century, the frequency of Atlantic tropical cyclones and hurricanes in a regional climate model of the Atlantic basin is reduced compared with observed boundary conditions at the end of the twentieth century. This is inconsistent with the idea that higher levels of atmospheric greenhouse gases will result in increased Atlantic hurricane activity.

The recently published 800,000-year greenhouse-gas records from Dome C, Antarctica, show that old ice still bears surprises. As long as the records challenge our understanding, we should go back for more. (Editorial)

The Garnaut Climate Change Review was required to examine the impacts of climate change on the Australian economy, and to recommend medium- to long-term policies and policy frameworks to improve the prospects of sustainable prosperity. This draft report describes the methodology that the Review is applying to the: evaluation of the costs and benefits of climate change mitigation; application of the science of climate change to Australia; international context of Australian mitigation, and Australian mitigation policy.

This report offers a comprehensive analysis of a suite of climate policy initiatives associated with a cap and trade program with the goal of identifying those empirical and design issues that most influence the economic consequences of their enactment. Empirically, present-value policy costs heavily depend on the actual outcomes of household consumption-saving and labor-leisure decisions, the magnitudes of and any induced changes in sectoral demand elasticities and technological trends, and the resulting time paths of permit prices and market interest rates.

African leaders at a development summit with Japan pledged Friday to take action to reduce greenhouse gas emissions as part of the fight against global warming. Global negotiations to draft a new climate treaty covering after 2012, when the Kyoto Protocol? obligations to slash emissions expire, have been bogged down by disputes between wealthy and poor countries.

In the face of skyrocketing petrol prices, the New Zealand government has said that it would delay the introduction of a new petrol rates under the emissions trading scheme (ets) for two years.

For seven long years, President George W. Bush has refused to confront the challenge of climate change and provide the leadership that America and the world needs to reduce greenhouse gases and avoid the destructive consequences of global warming.

Major industrialised countries are expected to create a multibillion-dollar fund later this year to help developing countries cut greenhouse gas emissions, World Bank President Robert Zoellick was quoted as saying. In an interview with Japan's Asahi newspaper published on Thursday, Zoellick said the fund would likely be finalised at the Group of Eight summit to be held on Japan's northern island of Hokkaido on July 7-9.

The Bush administration released a climate change assessment on Thursday -- four years late and pushed forward by a court order -- that said human-induced global warming will likely lead to problems like droughts in the US West and stronger hurricanes. President George W. Bush's stance on the issue has evolved from denying climate science to acknowledging that global warming is happening. In March, watchdog groups said Bush's decision to intervene in setting air pollution standards was part of a pattern of meddling in environmental science.

Rich nations need to cut per-capita greenhouse gas emissions to India's current levels by mid-century to avoid devastating climate change, Britain's former chief scientific adviser said on Wednesday. Global carbon dioxide (CO2) levels from burning fossil fuels were already rising quickly and rich nations needed to quickly figure out how to maintain economic growth while committing to deep cuts in emissions, said David King.
