Climate change has turned permafrost into a carbon emitter

And it&#x27;s quite scary if you consider the amount of methane stored in Siberia and northern Canada.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Clathrate_gun_hypothesis" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Clathrate_gun_hypothesis</a>

I believe this same dynamic will apply to the oceans as they warm. They&#x27;re like a can of Coke. Heat it up and the carbonation goes away. It&#x27;s a horrifying positive feedback loop of global warming.

I&#x27;m really curious about marine cloudseeding as a potential mitigator to permafrost melt. Essentially, high-efficiency saltwater aerosolization to create nuclei for cloud formation...<p>Here is a 2019 paper on the critical role of clouds in arctic cooling <a href="https:&#x2F;&#x2F;www.nature.com&#x2F;articles&#x2F;s41598-019-44155-w#Sec7" rel="nofollow">https:&#x2F;&#x2F;www.nature.com&#x2F;articles&#x2F;s41598-019-44155-w#Sec7</a>

Tropical forests are also now a carbon emitter:<p><a href="https:&#x2F;&#x2F;www.carbonbrief.org&#x2F;tropical-forests-no-longer-carbon-sinks-because-human-activity" rel="nofollow">https:&#x2F;&#x2F;www.carbonbrief.org&#x2F;tropical-forests-no-longer-carbo...</a>

The world would be a much better place if Al Gore had won.

Worth noting that this research is about co2 specifically and not methane.<p>&quot;... the research didn&#x27;t measure methane, a greenhouse gas about 30 times more potent than carbon dioxide that is also released from soil.&quot;

Why on earth is there methane trapped in the permafrost?

Carbon is not a synonym for carbon dioxide.

Regardless of the truth of this story and the facts surrounding climate change Canadian media is not a credible source of information.<p>The CBC gets $2 BILLION&#x2F;yr from the Trudeau Liberal government. All other private news orgs have a hand in a $600 Million&#x2F;yr pot. For example, the Toronto Star alone receives $5.2 Million&#x2F;yr from the Canadian federal government.<p>We can all agree this is a bad system apt to produce favourable results for the Liberals. For example, they won re-election on Monday.
