Rising global temperatures bring dire threats, such as floods, heat-related injuries, water scarcity, and hunger, making up to 3.6 billion people – nearly half of the world's population – highly vulnerable to climate change.
"We Are in an Emergency": The Key Actions From The UN's Major New Climate ReportRising global temperatures bring dire threats, such as floods, heat-related injuries, water scarcity, and hunger, making up to 3.
Under 1.5 degrees of global warming, children ages 10 and younger as of 2020 could experience a nearly four-fold increase in extreme weather events by 2100. Eight million to 80 million people will suffer from hunger by 2050. Under a high-warming scenario, up to 183 million additional people in low-income countries could become undernourished due to climate change.
"The world we live in today is not going to be the world we live in five years, 10 years, or even 20 years from now," Debra Roberts, the co-chair of the IPCC report, said at the press conference."We have to be much more vigilant about our actions."Governments and industries have taken some measures to adapt to their new climates and prepare for impacts to come.
"The tricky thing is that there is no silver bullet.
