The conference of parties to the un climate convention in Nairobi went along predictable lines. In the 12 years of the convention, political rhetoric may not have changed much

Sudden global warming 55 million years ago provides evidence for high climate sensitivity to atmospheric CO2, but the source of the carbon remains enigmatic.

marine life stirs oceans enough to affect climate, says a study by scientists of the Florida State University. Movement of winds and water has a bearing on climate. Previously, it was thought that the difference in temperature resulted in the movement of water and hence different climatic conditions, but the role of marine organisms was not highlighted.

The source of the proposal was almost as remarkable as the idea itself.

Just imagine

Monthly and 3-hourly precipitation data from twentieth-century climate simulations by the newest generation of 18 coupled climate system models are analyzed and compared with available observations. The characteristics examined include the mean spatial patterns, intraseasonal-to-interannual and ENSO-related variability, convective versus stratiform precipitation ratio, precipitation frequency and intensity for different precipitation categories, and diurnal cycle.

Melting Himalayan glaciers are threatening to unleash a torrent of floods into mountain valleys, and ultimately dry up rivers across South Asia. A new study, due to be presented in July to the International Commission on Snow and Ice (ICSI), predicts that most of the glaciers in the region will vanish within 40 years as a result of global warming.

Global climate change is today a spectre which allows for no ostriches. Scientific data is piling up to indict human activity as the source of the current phase of warming. The debate is whether the affluent North or the developing South has been more responsible and who will be polluting more in the near future.

This document contains the summary for Policymakers: The Science of Climate Change - IPCC Working Group I.

It details the following key features:
1. Greenhouse gas concentrations have continued to increase
2. Anthropogenic aerosols tend to produce negative radiative forcings
3. Climate has changed over the past century

A 4.80 m long shallow water sediment core, collected from the inner shelf (at 22 m water depth) off Karwar, near Kali river mouth is studied for foraminiferal tracers of palaeomonsoons. The climate history of this core which represents the last 4,500 years approximately revealed the evidences of a significant change in the intensity of the precipitation around 2,000 years BP.
