The termination of the Marinoan glaciation 635 million years ago is one of the most spectacular climate change events ever recorded. Methane release from equatorial permafrost might have triggered this global meltdown.

What should we do about climate change? The question is an ethical one. Science, including the science of economics, can help discover the causes and effects of climate change. It can also help work out what we can do about climate change. But what we should do is an ethical question.

Changes in extreme weather and climate events have significant impacts and are among the most serious challenges to society in coping with a changing climate. This report provides current assessments of climate change science to inform public debate, policy, and operational decisions.

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.

Tajikistan is battling a locust invasion, which the government says, has come a month earlier than usual. The infestation was first reported in southern districts of Tajikistan on March 18.

Professor at Germany's Potsdam Institute for Climate Impact Research, Anders Levermann's interests range from monsoon in India to glacier melt in Antarctica. He has contributed to the fourth assessment report of the Intergovernmental Panel on Climate Change released last year. He talks to Mario D'Souza on the geopolitics of climate change

Climate change is for real

even though the earth is heating up there could be some relief, say recent studies. And we have to thank the Atlantic Ocean for this respite. Researchers at Leibniz Institute of Marine Sciences,

While studies indicate that global temperatures may not increase over the next decade, there is no respite for the Arctic sea ice, this year at least. There are very high chances, about 60 per cent,

rat find: A team of scientists has rediscovered the greater dwarf cloud rat (Carpomys melanurus), last seen 112 years ago. It was in the canopy of a large tree, on a large horizontal branch covered
