I'm not a 'scientist' or 'climatologist' (aka glorified weatherman/woman) but I am fairly observant and try to avoid the bias of sites like reddit and ars.

Living in the North East U.S. I go out side in July it is 80F.  In January I go outside and it is 10F.   Next year I go out side in January it might be -10F and in July it is 105F.. thousands of years ago it was covered by a glacier.  they call it climate change or global warming.. I call it weather.. or seasons.

To deny climate change happens at all is just silly.  It happens.  It has been happening since forever.  At one time earth consisted of one land mass with a large ocean.   The land masses are still moving and will continue to do so.. I wonder if that has effect on climate?  These volcanoes erupting this month.. wonder if that will effect climate?

The problem is how much effect humans have had on the change in the climate and what the 'greenie weenies' want the climate to be? What would make them happy.  I've concluded that nothing will, it is this generations' power play.

farming changes the climate.  Eating meat changes climate... being a vegetarian changes the climate.. using coal electricity changes the climate... using 'green' energy (solar, wind, hydro) changes the climate.  pretty much everything we can do changes the climate. 

Personally I think the greenies should go back and work on things that they could really make a difference in.. like pollution, reducing waste and such.  Everyone likes green grass, clean water and clear skies.  Start in the nations that are now starting to industrialize like China, I haven't heard about large amounts of smog in the US in quite sometime (good job!)

There has been enough data either falsified or mishandled about climate change to seriously question the 'experts'.  Of course it doesn't help when they recruit spokesmen(woman) who are hypocrites on the matter.  It's like having Adrian Peterson teaching child discipline classes.  Just doesn't work

To call it the Largest threat to man kind is one of the dumbest things I've heard.  Humans adapt to climate.  If there is a flood you get out of the way or re-route it.  Things like asteroids hitting the earth, another world war, another plague, zombies  or another Star Trek movie directed by JJ Abrams are bigger threats.

TL;DR politicized science is not science.  Do your part by not polluting and reducing your waste and don't panic.  Just my opinion
