US Heat Waves To Skyrocket As Globe Warms, Study Suggests (usatoday.com) 395

An anonymous reader quotes a report from USA Today: As the globe warms in the years ahead, days with extreme heat are forecasted to skyrocket across hundreds of U.S. cities, a new study suggests, perhaps even breaking the "heat index." By 2050, hundreds of U.S. cities could see an entire month each year with heat index temperatures above 100 degrees if nothing is done to rein in global warming. The heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature. This is the first study to take the heat index -- instead of just temperature -- into account when determining the impacts of global warming. The number of days per year when the heat index exceeds 100 degrees will more than double nationally, according to the study, which was published Tuesday in the journal Environmental Research Communications. On some days, conditions would be so extreme that they'd exceed the upper limit of the heat index, rendering it "incalculable," the study predicts. What is there to be done about this? "Rapidly reduce global warming emissions and help communities prepare for the extreme heat that is already inevitable," report co-author Astrid Caldas said. "Extreme heat is one of the climate change impacts most responsive to emissions reductions, making it possible to limit how extreme our hotter future becomes for today's children."

        That isn't enough. Sure it will help.

        But trees only take in a certain amount of carbon, then the tree dies, and releases it. So eventually we will run out of places to plant enough trees.
        Then there is the whole "they need water" thing. Because, yes, sure, it looks like a lot of rain in Louisiana these days, but I'm certain that's not the only place we need to put those pesky trees, and most of the places that need them the most, does not have enough fresh water as it is...

          Trees uptake carbon until they die. Interesting part about the forest cycle, is that there's an entire microbiological ecosystem that exists on also using the CO2. Trees "don't release it." It's why you see those massive areas of limestone that can be a couple of KM thick I mean, the area I grew up in the limestone is around 400m thick. Depending on the type of tree determines the amount of carbon uptake, fast growing pines for example take more in 20 years then say a hardwood does in 40 years.

The latter could even be spun in a way to appeal to many right wingers by pointing out how powerful Islamist states (rogue and "friendly") are continuing to get rich by pumping free money out of the ground.

          You want a way to convince "right wingers" to favour electric cars? Here's a simple one - get the price of the vehicle down to $15K or so, rather than $30K or so. The average person in America can't really afford a car (or two or three, if we're talking a family) that costs $30k (or $60k or $90k, if we're talking a family), so they're not buying them much. And there's not much of used EV market yet, since they haven't been around long enough for that (never mind that a used EV probably has a battery in bad enough shape as to seriously impact range)....

    This is a criticism I've had of environmentalists for a long time. For their position to be justified, there has to be just the right amount of global warming occurring. It has to be bad enough that we have to abandon fossil fuels, but not so bad that we should switch ASAP to the one power source which is carbon-neutral and we can already scale up to supply all our needs - nuclear. To them, the amount of global warming occurring falls into the narrow band that's just the right amount for our best course of action to be to pour money into developing renewable energy source.

    Likewise, they feel it can't be so bad that we have to adopt more radical methods of carbon sequestration. To them, global warming is occurring quickly enough that drastic action is needed, but not so quickly that recycling is still "good enough". Recycling paper and wood products (composting) is carbon neutral - it's like having perfect defense in a basketball game. It does you no good if you're already losing the game. It can stop you from falling further behind, but it won't let you win the game. We're probably well past the point where stopping CO2 emissions will be enough. We're going to have to come up with ways to actively remove CO2 from the atmosphere and sequester it underground. Mainly, chopping down trees and burying them (i.e. replacing the trees which died millions of years ago which we dug up and burned as coal and oil). Then planting new trees to replace the ones we cut down so the rate that global vegetation pulls CO2 out of the atmosphere isn't reduced. This means no more recycling paper - it's better to throw used paper away in landfills to sequester it underground. Likewise, composting needs to be reduced to only whats necessary to recycle nutrients. Excess landscaping debris (like grass clippings) should also be sent to landfills to sequester the carbon underground.

    But they won't accept these radical solutions because their primary goal isn't to stop global warming. Their primary goal is the adoption of renewables and recycling - you can tell because they stick to that goal even if it results in more global warming (renewables unable to provide the necessary power so more coal and gas plants get built, recycling paper reduces the amount of carbon being sequestered underground). To them, global warming is merely a convenient reason to justify adoption of their preferred solutions.

    If you're chanting the mantra of renewables and recycling, you seriously need to ask yourself: "What's your real goal?" Is it the adoption of renewables and recycling? Or is it to save the world from global warming? If the latter, then you need to be receptive of options which accomplish it which may not rely on (or may even contradict) renewables or recycling. Renewables and recycling can be part of the solution. But if you automatically dismiss out of hand any other solutions simply because they don't involve renewables or recycling, then you are part of the problem which is driving our climate to disaster.

      Same here. I cannot take them seriously until nuclear power is considered part of the solution to get us out of this CO2 hole. First step is to stop digging. Second step is to start filling in the hole.

      Burying trees is a bad idea. At least not until we use the wood for building material first. We can sequester a lot of carbon in wooden structures, as well as furniture, fencing, or whatever durable goods we can think of. When they reach end of their useful life then we can bury the wood.
