    Denying climate change? That’s so yesteryears and a wonderful strategy to win, given that we are very likely in the midst of the hottest days, years, and decades.

    And many “conservatives” while publicly denying climate change are dealing with its affects. Trump sought funding to deal with increased storm and erosion to protect his golf courses. Many Republican politicians have sought federal help for dealing with increased flooding and access to freshwater in areas seeing droughts.

    DeSantis in his first term took measures to protect FL’s coastline from erosion and the Everglades.

    Once upon a time 30 years ago, scientist predicted that by the 2020's there would be massive global heatwaves, extreme flooding events would be common place, continental wildfires would rage every summer, reefs would bleach, polar vortexes would meander south, and storms would increase in severity. They were called crazy. Crazy!

    2025? My body is not ready.

    https://www.theguardian.com/environ...ould-collapse-as-early-as-2025-study-suggests


    The Gulf Stream system could collapse as soon as 2025, a new study suggests. The shutting down of the vital ocean currents, called the Atlantic Meridional Overturning Circulation (Amoc) by scientists, would bring catastrophic climate impacts.

    Amoc was already known to be at its weakest in 1,600 years owing to global heating and researchers spotted warning signs of a tipping point in 2021.

    The new analysis estimates a timescale for the collapse of between 2025 and 2095, with a central estimate of 2050, if global carbon emissions are not reduced. Evidence from past collapses indicates changes of temperature of 10C in a few decades, although these occurred during ice ages.


    Other scientists said the assumptions about how a tipping point would play out and uncertainties in the underlying data are too large for a reliable estimate of the timing of the tipping point. But all said the prospect of an Amoc collapse was extremely concerning and should spur rapid cuts in carbon emissions.

    Amoc carries warm ocean water northwards towards the pole where it cools and sinks, driving the Atlantic’s currents. But an influx of fresh water from the accelerating melting of Greenland’s ice cap and other sources is increasingly smothering the currents.

    A collapse of Amoc would have disastrous consequences around the world, severely disrupting the rains that billions of people depend on for food in India, South America and west Africa. It would increase storms and drop temperatures in Europe, and lead to a rising sea level on the eastern coast of North America. It would also further endanger the Amazon rainforest and Antarctic ice sheets.



    The potential collapse of Amoc is intensely debated by scientists, who have previously said it must be avoided “at all costs”.

    Prof Niklas Boers, from the Potsdam Institute for Climate Impact Research in Germany, revealed the early warning signs of Amoc collapse in 2021. “The results of the new study sound alarming but if the uncertainties in the heavily oversimplified model [of the tipping point] and in the underlying [sea temperature] data are included, then it becomes clear that these uncertainties are too large to make any reliable estimate of the time of tipping.”

    Prof David Thornalley, at University College London, UK, agreed the study had large caveats and unknowns and said further research was essential: “But if the statistics are robust and a relevant way to describe how the actual Amoc behaves, then this is a very concerning result.”

    Dr Levke Caesar, at the University of Bremen, Germany, said using sea surface temperatures as proxy data for the strength of the Amoc currents was a key source of uncertainty: “We only have direct observational data of the Amoc since 2004.”

    The extrapolation in the new analysis was reasonable, according to Prof Tim Lenton, at the University of Exeter, UK. He said the tipping point could lead to a partial Amoc collapse, for example only in the Labrador Sea, but that this would still cause major impacts. Ditlevsen said he hoped the debate would drive new research: “It’s always fruitful when you do not exactly agree.”

    Prof Stefan Rahmstorf, at the University of Potsdam, Germany, said: “There is still large uncertainty where the Amoc tipping point is, but the new study adds to the evidence that it is much closer than we thought. A single study provides limited evidence, but when multiple approaches have led to similar conclusions this must be taken very seriously, especially when we’re talking about a risk that we really want to rule out with 99.9% certainty. Now we can’t even rule out crossing the tipping point in the next decade or two.

    Funny thing is that "el nino" still hasn't really started yet. It's next year that's suppose to really kick in, and thus next summer is going to be even worse.

    What utter scumbags. This country deserves two component governoring parties but sadly the GOP are MIA

    Well that settles it…. There is no man made climate change, we don’t need to anything

    Good old theory of superabundance. Yes technology will solve everything and human activity will not impact our environment or ecosystems.

    Lol, no.

    Next ice age was suppose to begin in like 50,000 years. Even I know that because when I was 10 years old, I wrote a school paper on it.

    On the surface it seems to buttress an already strong suite of ideas to attract independents:

    Fossil fuels
    Forced birth
    Woke
    Hunter
    Woke
    Guns
    Book bans
    Woke

    Edit: forgot to add Woke

    Good watch, zero political mentions until the final 20 seconds.

    That climate scientists back in the 70's thought that we might be headed for another ice age shows that climate science isn't a cult. If it were a cult and all driven by Socialist wanting to control things then we would still see IPCC still saying there was an ice age coming and regulatory measures have to be taken to address global cooling.

    That we don't shows that climate science actually assessed new evidence and rather than defend an orthodoxy actually came to a new consensus.

    Why don’t we just put all the climate activists to a cow farm and tell the cows not to fart
