Global warming does not matter.

First Pericles, rarely have I encountered anyone who appears to lack even an ounce of empathy (see a description of empathy here).

I dare you to submit any substantial proof that the global-warming we're experiencing currently is not being accelerated by human activities.

I don't doubt that there have been countless "natural" (even quite drastic) climate changes in the past. But I reckon that most of these were gradual enough to allow life sufficient time to adapt.

However, you appear to "crow with joy" in announcing:

About 70, million years ago average global temperatures were 15 degrees F higher than now. The planet has another 5 billion years to go before it is destroyed by the sun turning into a red giant. Don't worry about it! Humans, on average live for about 22,000 days. Enjoy your boat.

As if what we as humans do has no consequence for every other life-form with which we share this planet.

Yes, in 5 billion years time, life on Earth will probably have become definitely insupportable. In the meantime, and over the next few generations, our children and their children, will likely be witness to one of the greatest disappearances of life on Earth outside of the great catastrophes which have lead to previous mass extinctions.

I don't doubt there will be human remnants here "up until the very end". You, or one of your descendents would have consummed my mother-in-law long before that, or one of mine yours. We homo-sapiens could have been a blessing, but in fact, we're probably "every other life-form's worst enemy".

So what, you may ask, if in 30 years time, we're informed "on Fox News" that the last known wild Polar bear's body has been found. "It was a female with 1 cub and had been hibernating. Rangers concluded that it had been attacked by a brown or grizzly bear venturing into new territories..."

I'm extremely saddenned by people like you. And your apparent total lack of empathy. You would "probably never in a billion years" be able to imagine yourself as a polar bear, a snow leopard, an arctic fox or any other of a 10,000 lesser creatures?!

You only went back 70 odd million years. "Far better for this planet" if we went back even farther though. To a time when the moon was so close that the tides "were measured in kilometres". And a time when people like you (and why not myself?) were if anything, merely very faint twinklings in the eye/s of some single-cell life-form existing at that time...
