Climate Change Could Hit India with Deadly Heat Waves

The average temperature in New Delhi has risen by one degree Celsius in the last century and a half, while also during that time the heat rose in the also populous Indian cities of Mumbai (0.7 degrees), Chennai (0.6) and Calcutta (1.2). That's double the pace targeted under the Paris climate agreements endorsed by nearly 200 nations in 2015.

"One of the key messages that come out very strongly from this report is that we are already seeing the consequences of 1°C of global warming through more extreme weather, rising sea levels and diminishing Arctic sea ice, among other changes", said Panmao Zhai, co-chair of IPCC Working Group I.

The Washington Post: The World Has Just Over A Decade To Get Climate Change Under Control, U.N. Scientists Say - "The radical transformation also would mean that, in a world projected to have more than 2 billion additional people by 2050, large swaths of land now used to produce food would instead have to be converted to growing trees that store carbon and crops designated for energy use". Global emissions need to be cut be 45% from 2010 levels by 2030, and renewables will need to make up at least 85% of electricity production by 2050 with coal use down to almost zero.

In order to reach this, society will need to make "unprecedented" changes including closing hundreds of coal-fired power stations and rapidly switching to renewable energy. The report acknowledged those changes would be hard and costly, but not impossible.

The 48th IPCC session in South Korea's western port city of Incheon brought together about 570 representatives from 135 countries and worldwide organisations, Xinhua news agency reported. "These options are technically proven at various scales, but their large-scale deployment may be limited by economic, financial, human capacity and institutional constraints".

Countries must take "unprecedented" action to slash carbon emissions to zero by 2050 and limit risky global warming, a key report has warned. But Scheer said his party remains adamantly opposed to a carbon tax, which he does not think will actually reduce emissions, and instead revert back to the regulatory approach taken by the former Conservative government.

The report stresses the need for measures to take carbon out of the atmosphere, such as planting forests or using land for crops to burn for energy and capturing the carbon and storing it underground, known as bioenergy and carbon capture and storage (Beccs).

Those ambitions would mark a massive upheaval to the energy system, with coal now accounting for about 37% of power and gas at 24%, according to the International Energy Agency.

What is significant about 1.5C of warming?

Responding to the report, Prof Corinne Le Quere, from the University of East Anglia, said: "For the United Kingdom, this means a rapid switch to renewable energy and electric cars, insulating our homes, planting trees, where possible walking or cycling and eating well - more plants and less meat - and developing an industry to capture carbon and store it underground".

"The coal industry has no role in a climate-stable world", said Jan Erik Saugestad, chief executive officer of Norway's Storebrand Asset Management, which oversees $88 billion. I mean, this report started with the governments.

Scientists say Australia has a chance to save 30 per cent of the Great Barrier Reef if immediate global changes are made to stop temperature rises. On current trends the 1.5°C threshold could be reached as early as 2030.

"There will be 420 million people less suffering because of climate change if we would be able to limit the warming to 1.5°C level and we have certain areas in the world which are extremely sensitive", Mr. Taalas said.
