Carolinas are being swamped by these heavy rains and high winds from Hurricane Florence.

The best scientists in the world are all telling us that our activities are changing the climate.

I don't think it's a hoax. I think there's probably a difference, but I don't know that it's man-made.

Experts say that we have until 2030 to avoid catastrophe.

Hello again, I'm Warren Alney, and this is to the point's climate change update.

It may sound frightening, but the scientific evidence is that if we have not taken dramatic action within the next decade,

we could face irreversible damage to the natural world

and the collapse of our societies.

We're running out of time, but there is still hope.

I believe that if we better understand the threat we face,

the more likely it is that we can avoid such a catastrophic future.

Now that's David Attenborough at age 93, renowned English broadcaster and natural historian, and he's talking about climate change.

Now, a massive new study by the United Nations labels climate change, one of the primary ways that we, the human species, are destroying the natural world that

sustains us. In 1,500 pages, it summarizes 15,000 studies by 145 scientists in 50 different countries.

Among the very disturbing conclusions is this.

No less than 1 million plant and animal species are in danger of extinction.

131 countries, including the United States, approved the findings.

Kate Browman is a coordinating lead author of the UN report. She heads the Global

Water Initiative at the University of Minnesota's Institute on the Environment. Thank you so much for

moment, but first let me ask you a couple of general questions. Plants and animals become extinct.

That's part of the natural order.
