    The Sun is the one force that's actually guaranteed to one day destroy all life on Earth and ultimately swallow the planet itself.

    Of course when put into that context - everything we do, or can do, in a lifetime becomes futile.

    I suspect most people are looking at the timeframe of the next century or so, maybe the next, when discussing "Climate change", not several thousand years from now, or even in the case of the Sun billions of years.

    You're right in regard to the Sun being the ultimate energy source on earth of course, harnessing it's energy in a more efficient way is inevitable, and to be expected in the foreseeable future imho..

    And of course we should keep on observing and measuring its activity - collecting scientific data and preserving it for future generations may just be the most meaningful thing we CAN do in our lifespan.

    Mr. Muscheler is correct when he points out that 70 years worth of observations is negligible when discussing a star.

    I'll stay away from the "Global Warming" points you raise towards the end of your post, that seems to be a US political issue better suited for the other thread, here it's best we limit ourselves to discussing the Sun imho

    • This weekend's solar storm is nothing next to what's hit Earth before

      The tail end of a solar storm that erupted from the sun earlier this week is expected to smash into Earth's magnetic field this weekend, making the aurora borealis (also known as the northern lights) visible as far south as Chicago.

      It's the first bit of exciting space weather we've had in many months as we're in the calm period at the end of the current 11-year solar cycle. The smallish solar flare and associated coronal mass ejection that erupted Wednesday also pale in comparison with far stronger and more disruptive blasts that have hit us in the past and almost certainly will again in the future.

      Perhaps the most famous magnetic storm is the so-called "Carrington Event" in 1859. The storm came at the dawn of our modern technological era and all but knocked the young telegraph system out of commission temporarily while lighting up skies with colorful aurora as far south as current-day Belize and Thailand.

      Recently, an international team of researchers pored over many of the observations of the solar storms of 1859 to try to reconstruct the details. The resulting paper, published in The Astrophysical Journal, is loaded with otherworldly anecdotes.

      "At 10.26 p.m. (on Sept. 2) the light of stars of the third and fourth magnitude very much enfeebled," wrote George Neumayer, director of Australia's Melbourne Flagstaff Observatory, in 1864. "Beautiful rays through Pisces. During the last 10 or 15 minutes a beautiful red arc of light, extending from E. to W., and passing through the crown, had become almost stationary."
