The goal of the global Paris climate agreement, which was signed in 2015, was to keep the world's temperature from rising more than 2 degrees Celsius over pre-industrial times.
"Countries like India, with large populations dependent on the agricultural and fishery sectors, would be highly impacted", he said.
Temperatures are now about 1° C higher than preindustrial levels.
The Paris Agreement was adopted by 195 countries at the 21st Conference of the Parties to the United Nations Framework Convention on Climate Change in December 2015, and created to strengthen the global response to the threat of climate change. Coral reefs would decline by 70-90 percent with global warming of 1.5 °C, whereas virtually all ( 99 percent) would be lost with 2 °C. These heat-trapping gases are the byproduct of industrial processes such as refrigeration and can be eliminated from those processes by re-engineering.
There's only twelve years left to avert climate change disaster, and Scott Morrison's still throwing around words like "nonsense". The election of Donald Trump-who pledged to pull the USA out of the Paris Climate accord and aims to roll back transportation and power-plant emissions standards-has galvanized investors, building support for funds focused on environmental, social and governance (ESG) issues, as Barron's reported.
Henri Waisman, a senior researcher at Paris-based think tank IDDRI and one of 91 report authors, said the report's aim was to set out the types of transformation required as clearly as possible to inform discussions at United Nations climate talks and beyond. Any additional carbon dioxide emissions would require removing the harmful gas from the air. But IPCC also adds that the effectiveness of CO2-capturing technologies is still unproven on a large-scale. "If the current warming rate continues, the world would reach human-induced global warming of 1.5°C around 2040". "Every bit of warming matters, especially since warming of 1.5C or higher increases the risk associated with long-lasting or irreversible changes such as the loss of some ecosystems", co-chair of the IPCC Working Group II Hans-Otto Portner said.
This is why the latest report from the United Nations' Intergovernmental Panel on Climate Change (IPCC) makes for such alarming reading and demands immediate, concerted action from everyone - particularly our leaders.
Countries in the southern hemisphere would see the most drastic effects. With a 2°C rise, the impacts can be too serious for communities to adapt.
The report was requested when the worldwide community came together in December of 2015 for the Paris agreement, which aims to keep global warming within this century "well below" 2°C, with an ultimate target of 1.5°C.
So how can we make sure that warming does not exceed 1.5°C and take us into highly unsafe territory?
The review of thousands of scientific papers also said the spread of disease and economic damage and harm to yields of crops will be less severe at 1.5C than 2C, as will the extinction of species.
The world needs to make decisions now for the future.
"Limiting warming to 1.5°C is possible within the laws of chemistry and physics but doing so would require unprecedented changes", said Jim Skea, co-chair of IPCC Working Group III. The most-affected areas in India will be mega cities, coastal areas, high-mountain and small-island regions.
Rapid cutting of carbon from the economy can be achieved.
But he says our habits are already causing devastating impacts.
Rajeevan says India is already experiencing extreme weather events; the unprecedented rains that triggered this year's Kerala floods being an example. This will require acting on all fronts to rapidly reduce emissions by 2030.
The report explains why it's so important that we meet the 1.5 degree target, and how hard that will be to accomplish.
Zaelke said: "With the wolf of climate impacts at our door, time for our counter-offensive is short". A key question in the months preceding the report's release was whether the formidable target is still feasible at all.
