  1. What’s the fuss about? Trump says climate change is fake news and he’s going to “bring back coal”, and remove environmental laws to suit the petroleum industry. But only if they donate a billion to his election fund. Sounds fair to me!
    VOTE REPUBLICAN!

  2. Too little too late! The rate of accelerated warming has disrupted the ecosystem and the food chain humans rely on. Food and water are going to be a lot harder to come by.

  3. 12 years lost during GQP administrations in the fight against global warming – 8 during W. Bush and 4 during TFG. To all the younger generation out there, do you really want to put another GQP administration in the WH, ever again? If I were in your place, I'd vote in every election and NEVER vote for a GQP politician, ever.

  4. Hats off to Dr. Mann for bravely speaking out on the importance of quickly slowing the burning of fossil fuels to slow and stop global warming. He has been hounded by fossil fuel company agents and even members of Congress for speaking the truth. He was forced to bring a defamation lawsuit against defamers and recently won! Congratulations to Dr Mann, and many thanks for his outstanding science and courageous work standing up to the unfair attacks on him as a person and as a scientist!

  5. Joe Biden proves by all means and measures he is a hypocrite. Don’t worry that $95,000,000,000 he sent overseas for “WAR” recently and won’t used in an environmentally friendly way! Shelling and tank rolling and warcraft planes and choppers are undoing ALL of Biden’s climate goals and it’s funded with U.S.A. tax dollars

    Trump’s use of fossil fuels was stabilized and responsible.

  6. Mann knows absolutely nothing about ecology. Hence, his opinions regarding future outcomes are, for the most part, irrelevant. For money media obviously found their Mann.

  7. Decarbonizartion is foolishness. As bad as usung fossil fuels.
    Carbon and pollution sequestration coupled with biosphere building, especially with top soil renewal, is our best opportunity to save our culture and probably our species.

    Biofuels are our best option, and algae is the best producer.

    Biology sequesters carbon. Biology is our only hope.

  8. The trolls love to say it is too late because then we won't push for change and won't even try to decrease fossil fuel use. Don't let stupid people who are destroying the planet win! Vote blue – your life and planet depend upon it.

  9. Do NOT engage the Dialogue! Earth is a googleplex multivariant CHAOS! Mann's recast Chaos as a Hockey Stick! They're mesmerizing you, like the Snake does, back and forth, squeeze and relax. Soon you've got their ESG Compliance Report all filled out, with your Climate Tithe-Tax paid in full, and your N95 mask back on. It's a CON! RESIST!!

  10. I personally think that humans will not be able to turn this around because of money. Greed and disregard for those who need to live here in the future are prevalent traits among the 1% and the large companies the own throughout the world.

  11. The "hot models" that predicted this trend had been mostly ignored. Those same models which are being referred to here ("in line with predictions") which have been ignored also do not agree with things suddenly stabilizing if we stop burning fossil fuels. This is cherry picking facts to fill a narrative. Got to be able to sell a solution. After all, it is all about Capitalism first and foremost.

  12. UTOPIA IS OWED AND PAST DUE!! NO MORE 24 7 5 DAYS OR 8 HOURS .NO MORNINGS>ALL 45 AND OLDER RETIRED NOW!! 3HOUR DAYS PAST LUNCH.3 DAY WORKWEEK.WE ALL QUIT TILL NARCISSIST QUIT BOMBING AND THEFT OF OTHER COUNTRIES RESOURCES.LESS WORK LESS THEFT!!.AND REVERSE!!

  13. Lots of science deniers like John Robson and Paul Burgess who have zero background in science but somehow get far right wingers to follow them. Thank you for hosting an actual climate scientist.

  14. The weather it really hasn’t changed much because how far are you looking back so stop with this think Man is strong enough to change weather at will anything we do or don’t do we have no power to control EARTH 🌍 AND WE MIGHT FREEZE BEFORE HEAT UP

  15. Nope the tundra is not going to stop melting the ice caps will not stop melting and all other countries will be getting ahead they bc will not listen BIDEN LETS THEM DO WHAT EVER MAKES THE MOST MONEY THE ELITE WILL KEEP BIDEN BECAUSE HE IS EVIL

  16. THANK YOU, DOCTOR MANN.
    Congratulations on winning your lawsuit against the liars and defamers.
    If we had taken action 30 years ago – like cranking up all the alternative energy sources we would have met and fixed the problems with it that we are desperate to fix NOW, _but the Fossil Fuel Industry wanted to Make More Money_😠😠😠😠😠😠😡😡😡😡😡😡😡😡🤬🤬🤬🤬🤬🤬🤬🤬🤬

  17. Katie Phang, thank you for this segment. And thank you for pointing out that greed-driven climate-change deniers like Trump are the main obstacles to solving a truly existential problem.

  18. How about if everybody started washing the dishes by hand. That means filling up the sink of water turning it off and washing your dishes in that sink of water. Without wasting water. Imagine if all of the countries that use an electric dishwasher stopped. But that would be of people cared and they don’t

  19. Climate change refers to the fictitious long-term shifts in temperatures and weather patterns. Human activities by profiteering vultures and crooked politicians backed up by big tech, have been the main drivers of climate change

  20. "What can we do to slow it down?" Reduce our carbon footprints, like we did when COVID-19 shutdowns reduced oil consumption so much that the dealers were paying customers to take it away.

  21. I have 3 beloved step-children and so it pains me greatly to say this. But I can see no feasible way of avoiding climate catastrophe without shutting down our global capitalist and competitive system. And that appears extremely unlikely.

  22. QUIT DRIVING YOUR BIG TRUCKS /SUVs that get 8 mpg's…. dont reside in 3000 sq ft houses that need their own power plant to heat and cool. dont "run to the store" for 2 items… in her BIG 4 WHEEL DRIVE TRUCK!!! and finally… quit having 8 kids in the 3rd world and then expect all of them to have the US/EU standard of existence with 5 BIG SUV TRUCKS and have 8 kids each generation….. 8 billion ppl on a planet that was FULLLLL IN 1960 with 3 billion ppl using up the earths finite resources??? CMON… that is the ROOT PROBLEM of "the environment"…. TOOOOOO MANY PPL ON THE PLANET!!!!
