A new report has raised alarm about climate change and its devastating impact on the US economy and its population.
Climate change will shrink US economy and kill thousands, the US government report warned as quoted by CNN on Friday.
The report contradicts the strange comments by US President Donald Trump who repeatedly doubts climate change as a hoax.
On Wednesday, Trump tweeted, "Whatever happened to Global Warming?" as some Americans faced the coldest Thanksgiving in over a century.
However, the CNN article stresses t the science explained in these and other federal government reports are clear: Climate change is not disproved by the extreme weather of one day or a week; it's demonstrated by long-term trends.
Humans are living with the warmest temperatures in modern history, it said, adding that even if the best-case scenario were to happen and greenhouse gas emissions were to drop to zero, the world was still on track to getting warmer.
As of now, not a single G20 country is meeting climate targets, according to CNN based on the report.
It said the report warns that without significant reductions in greenhouse emissions, the annual average global temperature could increase 9 degrees Fahrenheit (5 Celsius) or more by the end of this century.
Higher temperatures will not only kill more people, but also, the costs of climate change could reach hundreds of billions of dollars annually, according to the report.
The report suggests that if the US reduced its fossil fuel use and greenhouse gas emissions immediately, it could save thousands of lives and benefit billions of dollars.
