Ask any environmental scientist. LOL Its not about is it getting warmer or colder in your area. The global warming is on a global scale so each year our global average tempature increases. According to USF its reaching the point of no return. But I know you don't have to be a scientist to see the climate change everywhere over the past 40 years. Just ask anyone over 40.That's news to me. Do you have any definitive proof global temperatures are on the rise?
Extraordinary claims require extraordinary proof.
Point of no return is a bit of a hyperbole. We got ourselves into this mess, we can get ourselves out of it. There are lots of activities that lead to global cooling. Particulates for example, there was an article a while back that speculated that the reason global warming was not as big an issue as a lot of people predicted is the particulates we are dumping into the atmosphere. Google global dimming.Ask any environmental scientist. LOL Its not about is it getting warmer or colder in your area.

And global warming/cooling has been cyclic. You only know the facts since the time of the current records.The global warming is on a global scale so each year our global average tempature increases.
Sure we can estimate. The earth is reported to be 4.5 - 4.6 billion years old, a minor error of about 100 million years or so. Human's counting and recording things is not very long in the overall picture.We can very accurately estimate temperatures over may thousands of years ago by analysing ice from Antartica.
Got a reference for that? Or should we just point that the industrial nations are in the northern hemisphere and the artic polar regions are melting. There was no change in the slant angle of the earth or anything else that could have caused that event.Interestingly, the increase of temperatures matches the start of the industrial revolution.
What does a more manageable problem look like? A 1C increase in temperature? Like everything else in this world, it takes cash to R&D, manufacturer, and hope the public will purchase your product.If we can change what we use to produce energy, then I think we have a much more manageable problem. I believe we should be switching to nuclear asap, and then investing more into hydrogen powered vehicles. Sure it might take more energy to create the hydrogen atm, but using clean energy to do this isn't quite as bad as using dirty energy.
?The 100 million years that is the "estimate error" far exceeds humans recorded temperatures and also exceeds the "thousands and thousands of years" of estimated temperatures.
So Ernie, still not convinced that the intensity of Hurricane Sandy had anything to do with global warming?That's news to me. Do you have any definitive proof global temperatures are on the rise?
