The history of humanity shows how slow it is to learn from mistakes. Nevertheless, we owe it to our children and grandchildren to not give up on them.

The planet won't work if a single species hoards all the resources. Through civilization, little more than a resource hoarding process, that's where we're increasingly at.

Over 50% of the seafood we eat would not exist without new farming techniques, for example.

The oceans are now saturated with excess heat. They have acted as a giant heat sink. Heat is energy. A method to turn the heat in seawater into electricity would mean that we could tap a huge energy reserve AND cool the oceans. People who haven't given up, or perhaps just don't enjoy scaring the shit out of everyone, are working on global warming.

Saying we are doomed encourages people to do nothing. He IS wrong. Join us and make a difference:

The oceans have more energy in them than they used to. But you can't convert that to any other form of energy unless you have a colder object to transfer some of the heat to - this is how a steam engine or jet turbine (or, effectively, an internal combustion engine) works - heat from the burning of fuel does work as it goes to the lower temperature surroundings (and, the bigger the temperature difference, the more work you get out - which is why jets are designed to run at as high a temperature as possible). So we'd need something cooler than the oceans to tap their energy - and something appreciably cooler to get a decent amount. But the air and earth warm up from global warming too, so there isn't a temperature difference to exploit. The best we could do would be exploit temperature differences between the top and depths of oceans (and there is research into that), but what you're doing there is moving the heat from the top into the deeper ocean - which may have consequences of its own (eg on currents).

While global warming is bad, nukes are a thousand times worse.

And given the ho-hum attitude the nuke deniers are humming, we're kicking that bucket.

Well, it was nice while it lasted.

insurance industry are or have woken up to this fact.

..... no one fixes a problem the effects of which has not been realized.

The realization of effects thus far are not extreme enough to be categorically attributed to climate change.

By the time the effects ARE exreme enough, it will be way too late to do anything that will make much difference.

Climate change is coming. Nothing is going to stop it or its effects. About all anyone can do is prepare, i.e. if you live on the Florida coast you might want to consider relocating
