The vegetation of India evolved in time and space due to geomorphologic changes and the interactions of climate and biotic changes. There is a close linkage between climate and biota. Jul-Dec 2007

This study investigates the impact of climate change on glaciers and glacial lakes in two major glacial hotspots in the Himalayas: the Dudh Koshi sub-basin in the Khumbu-Everest region in Nepal, and the Pho Chu sub-basin in Bhutan. The focus was on changes in the number and size of glacial lakes forming behind exposed end moraines as glaciers retreat, and the resulting potential threat of glacial lake outburst floods (GLOFs). The report aims to demonstrate methodological aspects of monitoring and potential GLOF hazard assessment using a case study approach.

The contemporary trend of global warming is aptly highlighted in the IPCC report 2007. There is a strong consensus amongst scientists and planners today that the earth's climate is entering a warm episode, nudged primarily by human activities of fossil fuel burning and land use changes that inject steadily increasing amounts of CO2 into the atmosphere. It is also quite possible that the increased concentrations of atmospheric CO2 will also have a direct influence on productive systems of plant species in view of increasing rates of photosynthesis and improved water use efficiency.

Too many people striving for too high a standard of living and purusing the so called "rates of growth" and "aping the unsustainable life styles" of the West are destroying the natural regulatory powers of the Earth.

Water is important for economic development, and many parts of India already face issues of water scarcity. This study predicts that intensity of rainfall will increase under climate change. Issues such as water scarcity may also become more prevalent. The marked rise in precipitation intensity and variability in

Ii the American Southwest heading for a megadrought? A projection based on climate models suggests this could be the outcome as global warming alters the Pacific weather patterns that normally bring rain to the region. Now tree rings are revealing just how dry things could get.

This report presents several case studies from selected natural and cultural World Heritage sites around the globe in order to illustrate the impacts of climate change that have already been observed and those that can be expected in the future. For each of the featured sites, ongoing and planned adaptation measures are reviewed, to give an indication of what may be possible by way of management responses to the different situations.

Climate models and satellite observations both indicate that the total amount of water in the atmosphere will increase at a rate of 7% per kelvin of surface warming. However, the climate models predict that global precipitation will increase at a much slower rate of 1 to 3% per kelvin. A recent analysis of satellite observations does not support this prediction of a muted response of precipitation to global warming. Rather, the observations suggest that precipitation and total atmospheric water have increased at about the same rate over the past two decades.

The World Health Organization (WHO) has calculated that by 2020 human-triggered climate change could kill 300,000 people worldwide every year.

This report describes what climate change is, including how it is affecting the world live in and the timeframe within which these changes are expected to happen.
