Earth’s climate will warm up over the next 50 years, whether or not greenhouse gases are curbed soon, a NASA study said.
If nations cut back on emissions, it will not heat up as much, but it will still be hotter than it is now.
If emissions continue to increase at the current rate, global temperatures may increase by 2-4 degrees Fahrenheit.
But if carbon dioxide emissions do not increase any faster than they are now then temperatures might only rise 1.4 degrees Fahrenheit.
