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.

I'm Warren Alney with a to the point climate change update.

What happens in the Arctic does not stay in the Arctic.

That's according to the director of the United Nations Environmental Program reacting to a new finding

that the Arctic region is trending away from what it's been in the 20th and 21st centuries

toward an unprecedented condition, there are implications for the rest of the world.

Scientists at the University of Alaska and the Geological Survey of Denmark and Greenland

have issued a video report, complete with dramatic music.

Based on observations since 1971, this study describes fundamental changes

among key elements of the Arctic physical and biological systems.

Associated with Arctic warming is an intensification of the hydrologic cycle,

with increases in humidity, cloud cover, rainfall,

increases in Arctic river discharge, increased snowline altitude, and accelerating loss

of land ice. John Walsh is chief scientist at the University of Alaska at Fairbanks Research

Center, which took part in the study called Key Indicers of Arctic Climate Change

1971 to 2017.

John Walsh, welcome.

Thank you.

What does this tell us that we didn't know before?
