Daily temperature records will tumble as sizzling early season heat from a summerlike heat dome sends thermometers skyrocketing into the triple digits in parts of California and the West this week.

The official start of summer is just a few weeks away, but it will feel like July in much of the West as temperatures climb 20 degrees or more above average, the highest temperatures of the year so far for many locations.

Excessive heat warnings are in effect for more than 17 million people in California, Nevada, Utah and Arizona this week. The warnings are the most extreme form of heat alert issued by the National Weather Service and are used when widespread, dangerous heat is expected.

The soaring temperatures are being caused by a heat dome, a large area of high pressure that parks over an area, traps air and heats it with abundant sunshine for days or weeks. The resulting heat becomes more intense the longer a heat dome lasts.

    No one is safe including the rich.

    The biggest major effect that global warming will have in the next few years or about 20 to 30 years is … mass migration. Once that starts in earnest, countries will be breaking out in conflicts everywhere. We aren’t cooperating with ourselves within our established borders now, what do you think will happen when millions of people start moving around to avoid the heat and more natural disasters.

    Everyone will suffer … the only thing the rich buy themselves is time because we are all headed to the same global environmental apocalypse.

    I feel good that I’m middle aged now because I will have lived my younger years when the world was doing relatively OK.

    I feel bad for anyone born right now because they’ll either see the beginning of the end or start surviving it.

      All of this has a silver lining: Dumping this much CO2 into our atmosphere will clearly signal that something weird is going on at interstellar scales, so maybe what’s left of humanity will finally make first contact. This is compounded if we use nuclear weapons during the resource wars.

        Space is big, any civilization analyzing the composition of exo planet atmosphereres wouldn’t know for quite a while. It’s for more likely that they wouldn’t discover it until after several decades of passed, at which point it will have been too late.

        That, and there’s the fact that first contact almost universally goes bad for the group with less technology, which is us in this case.

        So you may as well just start playing the lottery.

          The only hope I have left is a Star Trek civilization at some point in the future and this is the only path I see to it.

          Don’t take that from me.

            Star Trek required WWIII, a major nuclear conflict, and the Eugenics Wars for humanity to pull their head out of their asses and not immediately shoot the first Vulcans that came by to see what was going on with the warp drive that Zephram Cochran had just turned on.
