Melting of the Thwaites Glacier could rewrite the global coastline

It’s been over two million years since CO2 was above 400 ppm, as it now is today.

We are facing several feet of sea level rises in five years.
Six to ten feet in our lifetimes.

Yet STILL, my educated BIL scoffs at our “Liberal Hoax” notion that the recent generations burning trillions of tons of carbon into the atmosphere has ANYTHING to do with “Nature’s normal cycles” we’re seeing today.

A warming atmosphere is creating concern in the Arctic Circle and on the continent of Antarctica. The Arctic Report Card shows high temperatures, shrinking sea ice and extreme melting events are transforming the region. At the opposite pole, in Antarctica, a key ice shelf that sits in front of the Thwaites Glacier could break up much sooner than expected — within 5 years. William Brangham reports.

1. Show your head-in-the-sand BIL this graph and ask him to explain how it appears 'natural'

2. Right Wing Divisive Politics Has Brought This Hell Upon The Planet

 

Had they not politicized Climate changed and supported the science, we would be in a different place now.

And if lunatic fringe like Susan Sarandon and other like-minded idiots had supported the DEMOCRAT instead of third-party Nader and Stein (and encouraged others to do so as well) the world would be a different place. In the face of the RW threats, there's only ONE party who can keep them out of office, and it's not the Greens or any other. We have a defacto two-party system and when it comes to national elections... only ONE of two parties will end up in the White House... yet the egos and vanity (and resentment) of folks like Sarandon, Moore, West (and others who think Democrats are a "bowl of shit'') continue to compel them all to sabotage and kneecap Democrats.

10. In an alternate universe, a Supreme Court allowed a recount of Florida in their 2000 election.

And Al Gore won! I hate that universe. That's not quite right. I envy that universe. People in authority who respect science made so much difference there, not just for climate change, but fighting pandemics as well.

This kind of thinking always sends me down the rabbit hole of "what ifs." What if John F. Kennedy had ducked before that third shot? We'd have colonies on Mars by now.

You're right that we should learn not to pay attention to the distractions of third party candidates. I learned that lesson in 1980 when I foolishly voted for John Bayard Anderson. A wise friend explained the futility of that vote. It didn't really matter in 1980. Reagan won by a lot, 9.7% of the popular vote and 489 to 49 in the electoral vote.

5. If they can sacrifice their own children's health to "own the Libs"

… ignoring their grandchildren’s future is nothing to sweat over

Much less the human race

13. We must get out of Dodge

Before our property becomes Oceanfront.
We're on the coast, only 52'6" above sea level now.
Moving inland to 1600'+ above.

7. There's no "could" about it.

When it melts it will rewrite the global coastline.

9. They weren't very clear on how fast sea level will rise.

The ice shelf may break off within five years. That doesn't raise sea level several feet right away. It hardly raises it at all. What it does is begins the process of the West Antarctic Ice Sheet pouring into the ocean. That will still take decades more. By 2100, we may see all that sea level rise. In the next five years, we may see an inch or two of sea level rise. After that, the rate of rise will increase year after year, until the East Antarctic Ice Sheet is mostly gone (it's much bigger than the West), then the rate of rise will slowly decrease until we reach a new equilibrium.

I expect Miami to survive another fifty years, but not a hundred and fifty.
