The floods in India’s Uttarakhand State, which may have claimed as many as 5,000 lives, were prompted by an unusually high amount of rainfall. The disaster, possibly the largest so far this year, underscores what is at stake in the UN’s upcoming climate talks in Warsaw, Poland.

"We do know that in warmer climate situations, we expect the atmosphere to be able to hold more moisture, and therefore that heavy rainfall events will become more common in the future," said Andrew Turner, a monsoon expert with the Walker Institute for Climate System Research at the University of Reading.

The extreme event also puts a spotlight on loss and damage caused by climate change and the need for resources for help poor countries adapt - issues to be negotiated at the 19th Conference of the Parties to the UN Framework Convention on Climate Change (UNFCCC), which will be held from 11 to 22 November. Discussions on these matters have been moving slowly; some important related issues were not even raised at the recently concluded talks in Bonn.

Harjeet Singh, ActionAid's international coordinator for disaster risk reduction (DRR) and climate change adaptation, said the unfolding impact of extreme climate variability "is just a sample of the catastrophe our children will witness if we do not dramatically reduce emissions and prepare to deal with it.”

IRIN has asked experts from NGOs and governments what they would like to see happen in Warsaw and what they believe is realistically possible.
