There is no doubting climate change, when Earth was formed it was a barren rock. The climate changed millions of times since this globe we now live on was formed, if it had not changed, there would be no life here. It changed by the grace of whatever God you worship, or not, but it did change and it will continue to change till the Sun Novas. We as inhabitants of Earth should strive to adapt to climate change.
Now that will be some serious and permanent climate change!
