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.

NICE AND WELL RESEARCHED
A house on a hockey skate doesn’t seem like it would just slide through the snow. 🤓
stop spraying chemicals in the arctic, nothing to do with climate change‼️ grey skies everyday in fall winter time from Military planes spraying this stuff, alaska yukon norhtwest territories nunavut and northern quebec, im sure greenland as well.. ‼️‼️
Waste of money. Handouts for leeches.
Climate change old news intelligent people already knew that the climate changes from time to time. That's why they are called ice ages, plate tectonics, floods, etc. The earth has to replenish and constantly moving. The earth is literally mother earth.
So where are the Greta thunbergs of the world bitching and complaining

I’m a Northern Canadian… and I’ve NEVER BEEN SO SCARED … this hurts my heart soo much .!
Is there any way we could harvest this into energy?
Old time dig holes for water wells not explosion for Metalogy or resourceology like tha
Disturbing lack of Frostpunk references
how much is much? GIGATON.

These are missile Bunker's from 20k years ago… everyone is lying. Call MTG.
DON'T WORRY WORRY PEOPLE IN THE COMMENT SECTION, ALL POWERFUL SKY DADDY WILL SAVE US!! 😆😆
Let’s not harness the methane or anything 😂
Watching humans turn earth into Venus 😢
Do these computer models take into account the millions of uncapped abandoned oil wells that are pumping methane into the air?
I wonder if volcanoes play a part somewhere?🤔
