The earth's climate has a 2 billion year history of changing from freezing to warming. We have no reason to believe the earth will not continue on it's natural climate path. Have we done things to the environment that have effected the rate of climate change? That is a big question that has many answers ranging basically from yes to no, with so called evidence in both directions.
From what I have learned in my life, the honest truth about many things are often masked, changed or outright lied about. So, it is really hard to know who's "facts" we are to believe. The older I get, the less and less I trust what our government says. People are selfish and greedy as they have their own agendas to follow.
I do not know what to believe any more and quite frankly, I am glad I will be dead sooner than later. But, until then, I will continue to enjoy my life to the fullest, as usual.
