A recently released study says Yukon River salmon may become too contaminated to eat unless human greenhouse gas emissions slow significantly. KUAC’s Mary Auld reports.

National Weather Service climate expert Rick Thoman says there’s a good chance that all of Alaska will be warmer than normal in August and the next couple of months. But he says there’s near-certainty that coastal areas along the Gulf of Alaska and the Bering and Beaufort seas will be warm through October.


It’s been a chilly winter here in the Interior and elsewhere around the state. But for the Arctic Ocean, it’s been one long warm spell. That’s led to another record-low year for formation of Arctic winter sea-ice cover.


It’s been a relatively cool and snowy winter here in the Interior, compared with the past couple of winters. But climate experts say the Arctic has been warmer than average. They say that’s why it appears this year’s maximum Arctic sea-ice cover, measured near the end of winter, is likely to set another record for the smallest maximum on record.


Scientists who study Arctic climate say their research will suffer if the Trump administration goes ahead with big budget cuts reportedly under consideration for the National Oceanic and Atmospheric Administration. And they say the proposed cuts also would hinder meteorologists’ ability to forecast weather in Alaska and worldwide.
