Global Temperatures Likely To Exceed Key Limit For First Time 91

With October's initial temperature data in, 2024 will rank as the first calendar year in modern record-keeping in which global average surface temperatures exceed the Paris Agreement's aspirational 1.5C guardrail. From a report:Holding long-term warming to the 1.5-degree target compared to the preindustrial era is crucial for lowering the risk of triggering climate change tipping points, beyond which potentially catastrophic impacts have a higher likelihood of occurring, studies show. Holding warming to that target is viewed as necessary for small island states and other extremely vulnerable nations to avoid being wiped out by sea level rise, drought and other threats.

The data -- and proxy records such as tree rings and ice cores -- shows this year is likely to be the hottest in at least 125,000 years. Right now, the world is on track for as much as 3.1C (5.58F) of warming based on already pledged emissions cuts, assuming they are fulfilled. Copernicus Climate Change Service reported early Thursday that the year is headed for a temperature anomaly of more than 1.55C (2.79F) above preindustrial levels. Last year fell just shy of the 1.5C threshold relative to the 1850-1900 average.

      If you look into it you'll find the swing states in America had 7 hour wait times to vote. The secretaries of state were Democrats but they fucked up badly. When you're dealing with 7 hour wait times to vote people have work and kids and frankly they're just too exhausted from those things to stand in line for 7 hours. As a result 15 million fewer people voted Democrat.

      This was less of a problem for the Republicans because they motivate their base with fear and because they rely heavily on the baby boomers and older Gen x who have nothing but time.

      I don't know if America is ever going to have another election again. The Republican party has detailed plans to stop that. They're done just suppressing the vote they're going to just not allow it anymore.

      But if we do we need to do what we did with the DMV when the lines got bad and people had had enough. Laws were passed requiring no more than 15 minutes in line. That forced the state legislatures to stop fucking around and properly fund the DMV. It might require a constitutional amendment at the state level though but without it this is just going to keep happening

        Well if both sides face the same obstacles, and one side is more willing to endure them to vote, it seems to me that it's another mechanism of measuring the will of the people. It's not the most direct measure, but how is it that much different than people staying home by default rather than hardship?

        Not saying it's great... but one side had their shit together on motivating their base, and one did not. How they got there isn't really relevant.

      The problem is not exceeding any one particular number, it is that the number will keep rising indefinitely as long as we keep increasing the carbon dioxide in the atmosphere.

      Good ol' tragedy of the commons. A country increasing its CO2 output is beneficial for them (financially) but detrimental to everyone else long-term. Similarly, a country decreasing its CO2 output is detrimental for them (financially) but beneficial to everyone else long-term.

      Historically, humans have solved the tragedy of the commons problem by either fencing areas off or by enacting local regulations (enforced by the local monopoly of force). But when it comes to the climate, you can't fence off the atmosphere and you can't enforce regulations using force on a global scale (because there is no Earth Police). Personally, I think humans aren't suitably equipped from an evolutionary standpoint to tackle a problem like climate change, the planetary-scale cooperation and mutual understanding mechanisms required for that simply don't exist in our species. We are screwed.

      • A country increasing its CO2 output is beneficial for them (financially) but detrimental to everyone else long-term.

        It depends very much on the country and there are two competing effects. Short-term there is a boost to the economy from avoiding the expense of switching to nuclear and renewables this benefits just the country failing to switch. Long-term, for most countries there is a strong negative effect where farmland becomes unusable, rising sea levels require expensive coastal defences and/or mass migration etc.

    There are pledges to reduce emissions and then the reality that every year, despite these pledges, greenhouse gas concentrations continue to rise. Caveating +3.1C with "based on already pledged emissions cuts" is ignoring the evidence. Scientists need to stop ignoring the evidence that humans are failing to moderate their behavior.

    We are at +1.5C now and heading for at least +3.5C -- which is the equilibrium temperature for our current greenhouse gas concentration, but every year we increase, not decrease the greenhouse gas levels. As is clearly shown in this paper, temperature is a lagging indicator: https://www.ces.fau.edu/nasa/i... [fau.edu] The entire mass of the atmosphere is 1/5 the mass of the ice in Antarctica. There are a lot of heat sinks holding the temperature back from its ultimate equilibrium point, but the planet will get there eventually.

    And it looks like we have likely warmed the planet enough to initiate ever increasing microbial methane production which in ~70 years will become the primary driver of global warming. https://agupubs.onlinelibrary.... [wiley.com] .
