Global warming is a fact

It's been going on for the last 15,000 years (since the last Ice Age). The question in dispute is the extent of man's hand in increasing the speed of the warming. This article is an example of a past time when global warming occured but like so many articles it's frustrating in that there's no comparison to the conditions for the rest of the globe at that time (it may be there's no data or insufficient data to make a report).

People should be aware that the climate of Earth and it's atmosphere has always been in flux, the particular time reported on in this story represents one of the hottest periods. Right now we are considered to be in a period "between Ice Ages" which is another way of saying that it's eventually going to get a lot colder again. The question right now is how hot will it get before it starts getting cold again.

Personally I think too many people are making noise about the *how* of global warming and too few people are planning on how to deal with the changes caused by global warming.

Correct, but

All your statements are true, but I disagree with your opinion on
people needing to plan for the changes caused by global warming.
There is nothing we can do in our lifetime, nor our childrens'
lifetimes, to deal with the changes because those changes are
made over thousands of years. There's plenty of time for people to
react naturally to those forces. You can't "do something" about
everything, as much as you'd like to. I think what we can do
something about though is try not to contribute to and accelerate
global warming.

Let me rephrase the headline...

"Dramatic climate change is natural"

Notice, by the way, that the universe didnt end when the poles were warm. I bet the carabou were lounging around, saying to each other 'thank goodness it warmed up, I was freezing my *** off!'.

Look at the timeframe for that warm period

It predates all the animals we associate with the Artic.

Earth is still warming from the last iceage.

The Earth is still warming from the last ice age. It has had a number of cycles of heating and cooling over billions of years. The idea that man is causing the current warming trend is a lie. All the big players in the environmental movement want to use global warming as an excuse to destroy the U.S. economy. It's amazing that they aren't protesting Chinese pollution or Indian pollution, it's only the U.S. economy that they are targeting. And of course, you can't have environmentalism without daily forecasts of doom and gloom. They like to say we only have a few years before we all die. They have been saying that decades, at least since the propaganda book "Silent Spring".

We need to put CO2 back into the atmosphere where it was

Millions of years ago there were much higher levels of carbon dioxide in the air than there is now. That's because millions of tons of carbon are still in the ground in the form of coal and oil. We just need to put that CO2 back into the air as part of a plan to return the earth to what it was in the distant past. CO2 isn't the problem, it's the solution.
