Over the weekend, California's Dixie wildfire became the second largest in the state's history,

charring almost half a million acres.

Despite the efforts of thousands of firefighters, California's wildfires have turned hundreds of homes to rubble and ash.

That fire in Northern California is why at one point over the weekend, the city with the worst air quality of any in the world was Denver.

Here's a live look outside of the incredibly smoky and hazy sky in the metro area.

It smells like a bonfire when you walk outside.

Meanwhile in Nebraska, a group of friends rescued from a flooded elevator during the overwhelming flash floods this weekend.

A few people had to be pulled from neck deep water in an elevator in downtown Omaha where homes and businesses were flooded after a

torrential rain on Saturday. Streets completely unrecognizable as cars were floating down lanes and people were left stranded.

Now on any given day, you can find stories like this from all over the world and they're becoming more frequent.

That's one major takeaway from a new landmark report issued by the UN on Monday.

It found human cause climate change is leading to more and more extreme weather events.

And it's accelerating faster than we thought.

Those are the things that people in the U.S. are already observing in their own backyards, wildfires in the West,

the flooding that we see in the Midwest and the Northeast, the damage from hurricanes and the South.

Allison Krimman's is the Director of the National Climate Assessment at the White House Office of Science and Technology Policy.

She spoke to NPR Monday about the new UN report.

The overall message is that climate change isn't something that's happening far away to someone else

and some far off future time. It's really happening here and now.

Consider this. We knew climate change was happening.

Now we have new information about how fast and each day the consequences are becoming clear.
