Bill Gates is aiming to work more closely with Amazon.com Inc. Chief Executive Officer Jeff Bezos to combat a climate crisis that the Microsoft Corp. co-founder said could dwarf the current pandemic in fatalities and global impact. “The deaths will just go up over time as you get more heat waves, forest fires and, most importantly, lose the ability to go outdoors and do farming anywhere near the equator,” Gates said in an interview with Bloomberg Television’s Emily Chang. His book, “How to Avoid a Climate Disaster,” went on sale earlier this month. Unlike the pandemic, it’s hard to get people to focus on catastrophes that may be decades away in enough time to avert them. “It's a real test of humanity to invest in advance for problems that come later,” Gates said.
