WATCH: In Just 80 Seconds, Bill Gates explained climate change using squishy toys in YouTuber-style video

Bill and Melinda Gates released ir 2019 annual letter, reflecting on nine biggest surprises y witnessed in 2018. Coming in at . 3 is climate change, something that Bill Gates wants people to understand is dire, but also something that has potential of slowing down — if humans do something about it. But don't worry, Gates didn't simply write up a fear-mongering blurb about this 2018 surprise — he also demonstrated it in a YouTuber-style video, featuring squishy toys and a pie chart. 

In video, Gates explained that most people focus on electricity when it comes to reducing emissions. And even though electricity is one of biggest sources of greenhouse gases on earth (and yes, you should continue unplugging your charger when you're t using it), it's important to focus on or factors, too.

"People think, 'Hey, aren't we getting solar panels and windmills to be a lot less expensive, and isn't that helping reduce greenhouse gases?' And answer is absolutely," Gates said to camera. "But re is a lot more to do than just taking electricity to zero emissions. re's a variety of things that generate greenhouse gases."

Gates n broke down five largest sources of greenhouse gas emissions on earth. According to his pie chart, which is based on data from  IPCC, y are electricity generation (25 percent), agriculture (of animals and crops) (24 percent), manufacturing (21 percent), transportation (14 percent), and building operations (10 percent).

So, w that you're probably feeling sufficiently overwhelmed, how on earth are we going to combat this?! "We're gonna need a lot of change, a lot of invation to bring emissions from all those areas down to zero," Gate explained in video. OK, invators, get to work!

But what about aver person who wants to do ir part? Gates believes getting citizens on board starts with keeping m up-to-date on world's emissions, and on what y can do to help curtail m.

"But we need to do a much better job of informing people about challenges," Gates wrote in his letter. "It would help if media cover matched breth of problem. Solar panels are great, but we should be hearing about trucks, cement, and cow farts too."

It's great that Bill Gates is using his platform to keep his fans in loop on climate change, and hopefully his career as a YouTuber is only just beginning.
