"If you are neutral in situations of injustice, you have chosen the side of the oppressor. If an elephant has its foot on the tail of a mouse and you say that you are neutral, the mouse will not appreciate your neutrality." --Bishop Desmond Tutu

Facts are stubborn things

For 650,000 years, the CO2 levels in Earth's atmosphere have remained below 300ppm.  That's a long time...  and now?  Where are CO2 levels?  How about 390ppm.

And there's no sign that it's going to reverse anytime soon.  Basically, we're fucked.

This data, provided by NASA, indicates without a shadow of a doubt that humans are having a strong impact on the CO2 levels in the atmosphere.  There is no point in denying or arguing about it.
The current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years.
Denying the impact of humans on the atmosphere is like denying that the Earth is round or that we live in a Heliocentric universe.
