About global warming effect

As a spiritual person, do you know there is one pressing issue that's in my mind most of the time? Every time I read the papers, watch the news on TV or browse some internet portals, this topic will be there and it's appearing more regularly. And I can't even do anything about it unless humans come together. My gosh.... the worst thing is that there is still a sizable group of people who are adamant about its effect.

I'm talking about the global warming effect by the way.

The group of people who don't believe in its effect will argue that this is a natural cycle of the planet that occurs every few thousand years and we are happening to be stepping onto it at the right time.
