scratching at .8, just hopin'
Mitch your entire stint in the Senate has been over a decade of excuses, shut up.
Well, he's having a competitive re-election bit this year. Alison Lundergan Grimes, the current secretary of state of Kentucky, is running against him.

Let's just hope those excuses catch up with him this time.

Well, the senators are certainly doing a terrific job calling out the rampant climate denial bullshit. Shame the Republicans won't bother to listen.

This seems to me to be the Democratic equivalent of political theater. They're not hoping to convince the other party, they're just hoping to make it an issue that voters will notice and care about come election time. Now seems as good a time to push environmental concerns as any, with the water contamination incidents and a colorful variety of weather-related issues well-known throughout the US.
Furthermore, I think Guantanamo must be destroyed.

Okay, this could use a bump.

To borrow from the Religion thread, people like her are an example of how it's possible to be spiritual and scientific at the same time. Much applause; here's hoping she reaches people.

Hat Kid, everybody.
Remove the dash and space from the link.
I think I remember hearing about some theory or something that if the ice caps melted, it would radically change the ocean currents and trigger...something catastrophic or something, I dunno. Anyone know anything about that?

I think it's still mostly speculative at this point, but there's a big current called the Gulf Stream that you might be thinking of.

[up] Hmm, that we are only at the speculation stage is worrying.

Better hurry and melt these ice caps off for scientific observation to confirm or disprove the current theory.

If the Gulf Stream changes, that could be really bad. You know how the British Isles don't have severely cold winters even though the entire region is north of the 49th Parallel? The Gulf Stream is one of the big causes of that. If the Gulf Stream changed, we wouldn't have a "Day After Tomorrow" style apocalypse, but the UK and Ireland would get some very cold winters they aren't prepared for. It would probably effect Scandinavia as well, along with wherever the Gulf Stream redirects to.

The jet stream that holds back most of the arctic air's gotten messed up (that's part of why the Polar Vortex moved in), and that's a lot more minor than what could happen in the future. Toronto's supply of migratory birds is way down this year, because it snowed heavily after they arrived. Of course, the prediction for the summer is that it will be blisteringly hot. Like it has been the past few years.

Regarding the Gulf Stream: As the polar ice caps melt, sweet (and thus less dense) water enters the ocean and forms a kind of "cap" at the water surface that prevents the surface layers from sinking down (they do so because water evaporation is high and the salinitiy and thus density as well), slowing down the global circulation. A similar effect (from the Antarctic ice cap) is blamed for increased El Nino events in the South Pacific.

There would be two effects. One, Europe could face colder winters for a while. Second, without the humidity from the Gulf Stream the Arctic ice caps would collapse even faster (the formation of the Gulf Stream is, paradoxically, to a large degree responsible for the existence of the Arctic ice caps by supplying them with humidity). Once they are gone completely, the Gulf current would resume, although possibly changed due to different Polar-Tropical temperature gradients.
Also heard that the release of methane gas in the Arctic from global warming could be disastrous.

[up]Yeah, that's a big worry, not least because it's already started happening.
What's precedent ever done for us?
145 SeptimusHeap7th May 2014 02:03:24 AM from Laniakea , Relationship Status: Mu
The big worry is the so-called "clathrate gun" - the release of large amounts of methane in a short timeframe, causing extreme warming.

Some analysis blames the Permian-Triassic Mass Extinction on such fast warming - a mass extinction that is called "The Great Dying" because of its extreme extinction rate.

This guy is arguing against climate defeatism. And he's right. It's still not too late to make a difference. Even if much of the damage is already done, it's not too late to stop more damage.

Giving up here is the worst possible thing we can do.

Behind the rise of Boko Haram - ecological disaster, oil crisis, spy games

A decent read. He's a touch too "bleeding heart" for my taste at the moment, but he raises some important concerns, namely a possible growing relationship between anthropogenic climate change and organized violence. As I've understood it, the IPCC is studying the potential ramifications of ACC with regard to famine, disease, crop failure (which itself relates to famine and economic woes) and, of course, increased civil unrest and terrorism.

This needs exposure, because it's so damn novel - solar-powered roadways. Before people start calling bullshit or scam or what have you, actually look into the details and watch the videos. It's not just solar panels, they also have heating mechanisms to prevent ice from settling, LEDS for dynamic road markings that are visible at night, among other things...

They seem to be making this thing work. The main problem will be replacing existing road material.

That's kind of insane, but it reminds me eerily of Robert A. Heinlein's idea of rolling roadways powered by solar energy.
