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.

InDepth #46 Weird Weather Pt. 2

The Oklahoma News Report — Wed, 08 Sep 2021 20:29:24 +0000

Hurricane Ida was one of the most powerful hurricanes to ever strike Louisiana, and it wreaked havoc on the east coast as well. Was it the result of global warming? And how do we explain changing weather patterns here in Oklahoma? Are they temporary or permanent?
In this week’s “InDepth” discussion, we present “part 2” of our conversation with Oklahoma climate experts.

The Oklahoma News Report, hosted by Rich Lenz, is a weekly in-depth exploration of news and issues affecting all Oklahomans, featuring topical information and meaningful stories that provide context and meaning to educate and engage every citizen across the state.

Bill Gates on tackling climate change and the ongoing pandemic response

PBS NewsHour — Mon, 22 Feb 2021 23:45:45 +0000

All of us face the risk that extreme weather events like the recent one in Texas will become more common and more destructive occurrences because of climate change. Microsoft co-founder Bill Gates has studied climate change for years, and he has prescriptions in his latest book, “How to Avoid a Climate Disaster.” He joins Judy Woodruff to discuss.

How could a body of water as big as the Mediterranean just…disappear? It would take decades and more than 1,000 research studies to even start to figure out the cause — or causes — of one of the greatest vanishing acts in Earth’s history.

Does Climate Change Cause Extreme Weather?

Above The Noise — Wed, 06 Sep 2017 18:26:16 +0000

What role does climate change play in extreme weather?

TEACHERS: Get your students in the discussion on KQED Learn, a safe place for middle and high school students to investigate controversial topics and share their voices. https://learn.kqed.org/topics/

Fluctuations in weather happen all the time. But sometimes, those fluctuations can get extreme, making disasters like hurricanes and heatwaves more intense. What role does climate change play in extreme weather?

ABOVE THE NOISE is a show that cuts through the hype and investigates the research behind controversial and trending topics in the news. Hosted by Myles Bess and Shirin Ghaffary.

Extreme weather is on the rise. A recent study found that worldwide, there were almost two and half times more extreme weather events in the first decade of this century than in the 1980s. To tease out the relationship between climate change and extreme weather, scientists use something called attribution science. This technique breaks down how much climate change influenced the event versus normal variations in weather. To do this successfully, researchers use climate models. They’re basically computer programs that simulate how the Earth’s climate will change over time. Essentially, 2 models are created. Model 1 — the world without humans burning fossil fuels. And model 2, a world like ours now, where we do burn fossil fuels.

In general, climate change models can’t tell us if climate change is the cause of any particular extreme weather event, but they do indicate that climate change is making those events more severe. Climate change is causing higher sea levels and warmer waters, and that’s leading to stronger hurricanes and heavier rainfall. Going forward, the overwhelming scientific consensus is that if climate change continues at its current rate, extreme weather will only get more extreme.

What is extreme weather?
Extreme weather is when a weather event is significantly different from the average or usual weather pattern.

What is climate change?
A change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.

What is climate attribution science?
The effort to scientifically demonstrate which mechanisms are responsible for observed changes in the Earth’s climate.
