Climate Change Will Have Dire Consequences For US, Federal Report Concludes (cnn.com) 314

A new US government report delivers a dire warning about climate change and its devastating impacts on the health and economy of the country. From a report: The federally mandated study was released by the Trump administration on Friday, at a time when many Americans are on a long holiday weekend, distracted by family and shopping. Coming from the US Global Change Research Program, a team of 13 federal agencies, the Fourth National Climate Assessment was put together with the help of 1,000 people, including 300 leading scientists. It's the second of two volumes. The first, released in November 2017, concluded that there is "no convincing alternative explanation" for the changing climate other than "human activities, especially emissions of greenhouse gases."

The report's findings run counter to President Donald Trump's consistent message that climate change is a hoax. On Wednesday, Trump tweeted, "Whatever happened to Global Warming?" as some Americans faced the coldest Thanksgiving in over a century. But the science explained in these and other federal government reports is clear: Climate change is not disproved by the extreme weather of one day or a week; it's demonstrated by long-term trends. Humans are living with the warmest temperatures in modern history. Even if the best-case scenario were to happen and greenhouse gas emissions were to drop to nothing, the world is on track to warm 1.1 degrees Fahrenheit. As of now, not a single G20 country is meeting climate targets, research shows.

The costs of climate change could reach hundreds of billions of dollars annually, according to the report. The Southeast alone will probably lose over a half a billion labor hours by 2100 due to extreme heat. Farmers will face extremely tough times. The quality and quantity of their crops will decline across the country due to higher temperatures, drought and flooding. In parts of the Midwest, farms will be able to produce less than 75% of the corn they produce today, and the southern part of the region could lose more than 25% of its soybean yield. Heat stress could cause average dairy production to fall between 0.60% and 1.35% over the next 12 years -- having already cost the industry $1.2 billion from heat stress in 2010.

    500 * 10^6 hours / 81 years = 6.173 * 10^6 hours/year

    That's 6.173 * 10^6 / 52 = 1.187 * 10^5 hours/week.

    Given 10 * 10^6 working age adults in the Southeast, that's...
    0.012 hours per week per worker. Not a hell of a lot.

    This won't matter to half of the american population, because their party and "news" channel keeps telling them it's fake news, and that a cold winter is proof that there is no global warming. And with bots and morons posting youtube links as "proof" of the contrary, you pretty much ensure more people, ignorant on the subject or oblivious to scientific research, will bite.
    • "A cold winter is proof there is no global warming". No, but why don't we acknowledge that those long, cold winters mean than by 2100 and after a worst-case prediction of a 2-5C temperature raise, we will still have long and cold winters?. Last year my major city actually set a cold winter record, over 167 days where the temperature didn't exceed 0C [globalnews.ca].

      My faith in the scientific model of dire anthropogenic climate change started at about 30% in 1980, and has increased by about 10% per decade since.

      In any other area of science, this would be regarded as a rapid confidence ramp with respect to a wicked question of science, but stakes are very high with the planet hanging in the balance, so double standard.

      My faith in the dire economic projections is not ramping at anywhere near that rate. It's mostly just a giant FUD sundae, and neither the rigors of tradit

    That a recent study conducted on beliefs [theguardian.com] showed that most people who believed global warming was a hoax also believed in the New World Order, ancient aliens, that vaccines caused autism, that JFK was murdered by his own government and/or that their government was trying to replace them with muslims.

    I'm honestly curious why we even bother to discuss things, in that case. I have no objection to you believing whatever you like, but as people like that most certainly DO object to me holding to my views, I see no benefit in bothering to debate things. No, I don't hold those conspiracy theorists in high esteem, but why should that bother them? If they were secure in their views, it would be irrelevant.

    Does it really cause that much distress to anyone if we use solar rather than coal for power plants? You get exactly the same amount of power, or maybe more with solar these days. How is that interfering with your lifestyle? Does it really cause a problem to argue that Brazil and Indonesia should stop producing cash crops and replant rainforest? Wow, a few products you weren't even buying anyway go up in price by all of five cents. The agony. Let me see if I can shed a tear... wait... wait... sorry, no.

    For crying out loud, it has bugger all impact on anyone here. Not even your 401K will be affected, since the stock brokers will all transfer together, causing the stocks they switch to to skyrocket in price. Ok, you might actually make quite a lot of money on that.

    That's it. That's all the affect YOU will ever notice. You becoming a little bit richer, in a few years.

    I mean. The tragedy of having more money to spend.

    • And how exactly are we going to use solar instead of coal for power plants when the current technology is unable to replace coal with solar. My problem is that there are too many people who want to shut down the coal plants BEFORE anyone has built the solar plants to replace them.

        We already have. More than 50% of the energy in Britain comes from renewables, about a fifth in the US. If we move the subsidies propping up coal to solar, we could have 100% generated by renewables within three Presidential terms. It's not difficult. Trump's removal of legitimate subsidies for an emergent technology in order to prop up coal will slow down the switch from coal to solar. Slow, not stop. It hasn't stopped, despite Trump's efforts to bankrupt the industry and finance a bankrupt, obsolete alternative.

        It's that simple.

        Solar is not difficult to mass produce and, with adequate funding to produce isotopically pure silicon (which we can now mass produce) along with the other mass-producible improvements to the energy output, the same number of panels produced can produce double the energy. Simple arithmetic would suggest you then need less than half the solar panels. (Lower transmission loss through fewer connections and less wiring.)

        Since most people want solar heating, not solar electricity, to the home, it's trivial to have the government provide incentives to mass produce solar heaters (which don't require rare earths) and to encourage installation of those where they'd be of better value to the consumer, so as to conserve resources.

        Reversing the taxes placed on solar power in Nevada and a few other States, mandating compensation, requiring all new homes have direct solar heaters or solar panels installed as part of the Federal building codes, and providing strong incentives to install (such as providing exactly the same subsidies to those selling solar energy to the grid as are currently provided to coal-fired power stations) would solve many of the problems.

        I'm a fan of nuclear done right (waste contains radioisotopes that can be used to produce energy, so use them, sodium reactors can't have a meltdown, have superior efficiency and we have actually built those, there's no need to cut corners to save on costs since a good working reactor is cheaper than geoengineering by many orders of magnitude giving us plenty of margin). It takes ten years to build a reactor, although you can probably increase the parallelism to some extent.

        If you go all-out on solar, and build a nuclear reactor in each State, then in ten years you should have ample power to completely eliminate fossil fuel.

        I'd go further and build in each State the infrastructure and housing likely required for a fusion reactor, which I'd expect to be ready for construction in about ten years. If it isn't, you've housing that's more than adequate to house a fission reactor. Indeed, it should be of vastly superior grade. So, if fusion isn't ready, just build another fission reactor in each State. The modifications needed should be minor, if there are any at all. It's just a shell with easily maintained piping, generator and substation. (Since the subsidies for fossil fuel amount to $20 trillion a year, we can afford to go Manhattan Project on fusion for a ten year spree. If it can be solved at all, that should be more than sufficient.)

        So in the worst case scenario, in ten years solar and nuclear are major players, with wind and geothermal next, and in twenty years solar and all forms of nuclear (regardless of whether that's just fission or not) have doubled capacity. That's 2030 and 2040 respectively.

        Let's take that worst-case. We've doubled the energy from solar by capacity and again by efficiency. So, we're currently at 50 gigawatts, so that's 200 gigawatts. We subtract the 50 we currently have, since we're only looking at new capacity. 150 gigawatts. Since the US government official figures say that the current output is actually 50 terawatt hours, I am unsure exactly how the numbers are reached. But if we accept that both numbers are valid, then we end up with 200 terawatt hours of power, or 150 terawatt hours of increase.

        The state of the art sodium reactors are 880 megawatts per reactor, which is 21120 megawatt hours per reactor. The best reactors out there have an output of 13
