The early part of the last deglaciation is characterised by a ~40 ppm atmospheric CO2 rise occurring in two abrupt phases. The underlying mechanisms driving these increases remain a subject of intense debate. Here, we successfully reproduce changes in CO2, δ13C and Δ14C as recorded by paleo-records during Heinrich stadial 1 (HS1). We show that HS1 CO2 increase can be explained by enhanced Southern Ocean upwelling of carbon-rich Pacific deep and intermediate waters, resulting from intensified Southern Ocean convection and Southern Hemisphere (SH) westerlies.

PATNA: Emission of greenhouse gases that lead to global warming and climate change would be reduced by 20-25% in India by 2020 and 33-35% by 2030, Union minister for environment, forest and climate

East India is the most vulnerable to the impacts of climate change owing to its geographical and ecological diversity even though this region is least contributor in global warming.

Agronomist proposes genetic introgression to mitigate the after-effects of Green Revolution

In just 30 years, cities around the world will face dramatically higher risks from extreme heat, coastal flooding, power blackouts and food and water shortages unless climate-changing emissions are

It can be easy to overlook the monstrous scale of the Antarctic ice sheet. Ice, thick enough in many places to bury mountains, covers a continent roughly the size of the US and Mexico combined.

Major South African centres are at risk from the effects of climate change, says an international report.

The fact is that the storms of this year hold a mirror to our future

Global warming is expected to make vegetables significantly scarcer around the world, unless new growing practices and resilient crop varieties are adopted, warned researchers.
