Scientists are now 95 per cent certain that global warming is human-induced
Author: Arnab Pratim Dutta
The fact that gradual warming of the earth is caused by humans was reinforced by the latest assessment report from the Intergovernmental Panel on Climate Change (IPCC). The first of the three-part report, collectively called Assessment Report 5 (AR5), was released on Friday in Stockholm. It says that involvement of humans is clear in the alteration of the planet's climate patterns. It says that the changes in the climate patterns are unprecedented.
What it does is to reiterate that climate change is happening because of mankind. Will the report finally prompt nations to act?

The first part of the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) is out. The report of the Working Group I looks at the physical science basis for climate change. That is, it has examined the scientific evidence to infer why climate change is happening and what are the changes observed in the climatic systems. Though the detailed scientific report will be released on September 30, the summary report was released today in Stockholm, Sweden.
Nearly 27 per cent of India has undergone a climatic shift since the last study on drought areas
Author: Vibha Varshney
A CLASSIFICATION of drought-affected areas was done in India in 1973-74 when the Drought Prone Areas Programme (DPAP) was launched. It has been used since then for carrying out drought-proofing measures. However, researchers from the Central Research Institute for Dryland Agriculture in Hyderabad contend that it is time to relook at the classification.
Study says Pacific Ocean has kept global warming in check
Author: Indu Mathi S
EVEN though the concentration of green house gases has been steadily increasing in the atmosphere, the global mean temperature has remained arrested since the last decade. The reason behind this compelling phenomenon has largely remained elusive. Now, two scientists from the Scripps Institution of Oceanography, University of California, San Diego, US, claim to have found the answer: tropical Pacific Ocean.
Global warming poses threat to CO2-absorbing planktons
Author: Anshu Kumari
CLIMATE change and the resultant rise in ocean temperatures is likely to upset natural cycles of processing carbon dioxide (CO2), nitrogen and phosphorous in planktons (microscopic aquatic plants), suggests a study published in Nature Climate Change. Planktons remove nearly half of the atmosphere’s CO2 during photosynthesis and store it under the sea.
