The Arctic is experiencing global warming much faster than the rest of the world. A new study shows four times faster, in fact! One of the effects of this accelerated warming is the melting sea ice in the Arctic. And researchers off the southeast coast of Greenland have started to notice some surprising and alarming new guests.

A variety of exotic marine life have begun to move in, now able to live in the warmer waters. And while this may serve as a boon to some of the inhabitants of the region and its fishing economy, it also signals profound and likely permanent ecosystem changes and points toward the kinds of tipping points we may see if we continue emitting greenhouse gasses into the atmosphere. Tune into this episode of Weathered to learn about what some of the unexpected consequences might be from the warming Arctic to our jetstream and our Weather.

Weathered is a show hosted by weather expert Maiya May and produced by Balance Media that helps explain the most common natural disasters, what causes them, how they’re changing, and what we can do to prepare.

Arctic Sinkholes I Full Documentary I NOVA I PBS

NOVA PBS Official — Thu, 03 Feb 2022 02:00:11 +0000

In the Arctic, enormous releases of methane, a potent greenhouse gas, threaten the climate.

Colossal explosions shake a remote corner of the Siberian tundra, leaving behind massive sinkholes. In Alaska, a huge lake erupts with bubbles of inflammable gas. Scientists are discovering that these mystifying phenomena add up to a ticking time bomb, as long-frozen permafrost melts and releases vast amounts of methane, a potent greenhouse gas. What are the implications of these dramatic developments in the Arctic? Scientists and local communities alike are struggling to grasp the scale of the methane threat and what it means for our climate future.

A History of Earth's Climate

SciShow — Mon, 27 May 2013 16:30:36 +0000

Earth had a climate long before we showed up and started noticing it and it’s influenced by a whole series of cycles that have been churning along for hundreds of millions of years. In most cases those cycles will continue long after we’re gone. A look at the history of climate change on Earth can give us some much needed perspective on our current climate dilemma because the surprising truth is, what we’re experiencing now is different than anything this planet has encountered before. So, let’s take a stroll down Climate History Lane and see if we can find some answers to a question that’s been bugging Hank a lot lately – just how much hot water are we in?
