A Tale of Two Ice Caps: As Arctic Ocean Heads Toward Ice-Free Summers, New Study Shows Human Warming Takes Out 56% of Antarctic Sea Ice by 2050

3 Mar

It’s helpful to frame this as cold being vulnerable to heat, and the planet needing heat-free zones. We tend to be acculturized to see cold as a presence instead of an absence, but the relative absence of heat is critical for many life cycles.

Thus far, the Arctic has been ground zero for human-caused climate change. A combination of sea ice melt, albedo loss, a warming ocean that transports heat beneath a melting ice cap, regions of Jet Stream retreat into the far north, and an overburden of greenhouse gasses near the pole, among other factors, have all resulted in a very rapid pace of local warming.

Global temp anomaly

(Global surface temperature anomaly over the last month features a high degree of, very visible, Arctic heat amplification. Most global warming models show the Arctic warms rapidly first under human warming. Then, as second stage warming progresses, heat begins to spike over other regions of the globe.

While global warming totals about .8 C above the 1880s average, about 1/6th the difference between now and another ice age, but on the side of hot, Arctic warming has pushed above 3.0 C during…

    Scary. I’m still trying to get my mind around why we aren’t doing more about this. My dad watches FOXNews 24/7 and I asked him about it. He thinks climate change is real but that we can’t do anything about it. Deluded by the oil companies, I guess. Because we can do some things.
