But even with its description of the increasing impacts that lie ahead, the IPCC understates a key risk: "that self-reinforcing feedback loops could push the climate system into chaos before we have time to tame our energy system, and the other sources of climate pollution". But even a 1.5°C rise in temperature will be threatening to India.
The global scientific authority on climate change, the IPCC, said the planet has 12 years with which to possibly achieve the 1.5-degree target, but it would require "transformational" change across all areas of society.
The latest report from the UN Intergovernmental Panel on Climate Change calls for "rapid, far-reaching and unprecedented changes" to limit global warming to 1.5 degrees Celsius. We can't find any historical analogies for it. Climate change is happening and its effects are being felt all over the world. By midcentury, we have to reach net zero emissions.
Trump's administration has largely ignored calls to take steps toward reducing harmful carbon emissions and Trump said previous year he would withdraw the United States from the landmark Paris climate agreement.
Keeping the 1.5°C target would keep the global sea level rise 0.1m lower by 2100 than a 2°C target, the report said. Any additional emissions would require removing Carbon dioxide from the air. But IPCC also adds that the effectiveness of CO2-capturing technologies is still unproven on a large-scale.
Countries are already seeing an increase in extreme weather and rising sea levels as a result of the increase in average global temperatures of 1 degree above pre-industrial levels that has already occurred, the IPCC study said.
"And now more than ever we know that every bit of warming matters", Krug said. "As with present-day impacts of climate change, the impacts associated with crossing such thresholds in the future will impact poor and vulnerable communities first and worst".
At 1.5 degrees, the authors predict the Arctic Ocean will be free of sea ice once per century.
Perhaps shockingly, the panel noted that at the current warming rates, Earth's atmosphere will in less than one hundred years be 3 degrees Celsius warmer than it was before the start of the Industrial revolution, which is twice what the Paris Agreement stipulated in one of its scenarios.
And the report says, it would become impossible to produce enough food to feed the world's growing population.
They're often left by other levels of government to "carry the load" on both adaption to climate change and mitigation, he said, and Premier Doug Ford's decision to cancel cap and trade, has "dealt a blow" to greenhouse gas reduction.
The report explains why it's so important that we meet the 1.5 degree target, and how hard that will be to accomplish.
Small islands and coastal cities such as NY and Mumbai risk going underwater without the installation of sea barriers. "There will also be heat stress in cities and air quality will deteriorate due to high fossil fuel use".
'It was given to me and I want to look at who drew it, which group drew it, ' Trump told reporters at the White House on Tuesday, as he left for an Iowa campaign rally.
"At +2 degrees Celsius warming, Karachi (Pakistan) and Kolkata (India) could expect annual conditions equivalent to their deadly 2015 heatwaves (medium confidence)", it said. The United States already leads the world in reducing carbon-dioxide emissions. "In totality, how the rest of the world handles the climate rogue behaviour of the Trump administration will decide whether the world meets the 1.5°C goal or not".
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.
