Seabirds are sensitive indicators of changes in marine ecosystems and might integrate and/or amplify the effects of climate forcing on lower levels in food chains. Current knowledge on the impact of climate changes on penguins is primarily based on Antarctic birds identified by using flipper bands.

As it hurts agricultural productivity and environment, climate change could also have an adverse impact on the quality of life of farmers and tourism industry, particularly in the developing countries. Climate change will have a telling impact on the farmers. It will be harder for them to carry on in the increased temperatures, Mr M.V.K. Sivakumar, Chief of Agricultural Meteorology Division, WMO (World Meteorological Organisation), told Business Line. Recognising this, the WMO and UN Habitat (the UN body on human settlements) have started working to address this issue, he said.

In future, climate change is likely to be the single most significant cause of biodiversity loss, writes Sanjay Gubbi, assessing its overall impact.

Judging the effect of climate change on ocean currents could take longer than we thought. The circulation of warm water in the North Atlantic is suspected to be slowing, and the worry is that global warming is to blame.

Bali Island (Sundarbans), Feb. 11: With the Sundarbans, the world's largest estuarine delta sinking by 2.5 mm every year, thanks to global warming, the British Deputy High Commission yesterday initiated a program to combat the adverse impacts of climate change.

One of the emblems of the Antarctic, the king penguin, could be driven to extinction by climate change, a French study warns. In a long-term investigation on the penguins' main breeding grounds, investigators found that a tiny warming of the Southern Ocean by the El Nino effect caused a massive fall in the birds' ability to survive. If predictions by UN scientists of ever-higher temperatures in coming decades prove true, the species faces a major risk of being wiped out, they say.
