Only because the right defines it as such. Liberalism cannot be about control and anti-freedom. It is absolutely contrary to the word itself and it's history. Only the politicization and words of art by the right is befuddling your mind on this issue. Stop playing the game.

Yes it does, here's how. There is a natural carbon cycle that keeps a balance in the amount of CO2 in the atmosphere....The CO2 we are emitting is 4% more than the natural carbon cycle can handle, so it remains in the atmosphere. It adds up year by year. Pre-industrial CO2 was less than 300ppm and today it is over 400ppm, so humans are responsible for more than 25% of the CO2 in the atmosphere today....Not 4%.

I was hoping he would watch and learn why this is so and why those who perpetuated such BS should not be listened too. He'll just deny and link a blogger.

the last interglacial period global average temps maxed out at 74'f..and CO2 was much higher...had NOTHING to do with humans


see that is the problem.. the manmade crowd continually denies interglacial periods and the scientific/historical facts about them

Fascinating how the right-wing viewpoint is all of a sudden "We've always known climate change happened!". Because flat-out denial was the order of the day for decades. Remember Inhofe and his snowball on the Senate floor?

current Arctic sea ice extent is ~15 million sq kilometers ...

...almost 2 million sq kilometers short of the all time record high

for reference: Egypt is 1 million sq kilometers

2 Egypts less than the all time high....15 Egypts still there...the bears have nothing to worry about

The minimum extent of ice in the arctic ocean is clearly seen to trend down from around 7 million sq km in 1980 to around 4.5 million sq km today. The last few years there has been significant fluctuations, which does not negate the overall trend. This is a favorite tactic of deniers - they cherry pick a year to be their baseline, and then say "see, the temperature hasn't increased, or sea ice decreased, in the past x years." Just wait a few years, and the long-term trend always re-emerges.

She is a zoologist but the OP's link is based on a recent book release but at least she is credible, that doesn't mean she is correct. Loss of sea ice means they have to travel greater distances and burn more calories hunting. Some populations are stable but certain areas they have declined by almost half. There are plenty of organizations that's study polar bears that indicate their population is decreasing but as ususal the deniers find the needle in the haystack and that's the end of the debate.

No, climate science does not ignore past climates, but learn from them. I have no idea where you got that temp. info on the Eemian inter-glacial, but it's not correct, nor is the CO2....The CO2 was app. 280ppm and temperatures were 1 to 2 degrees C warmer than today.

At how many Egypts do you start to worry?
