Well, the sea and the waves roar in the winter too .. so heat is not an indication of such “sea” activity. I believe “Sandy” was a violent winter storm.
And the second reference is about when the anti-Christ reigns. It has nothing to do with today, or whether or not the earth is warming now.
Neither of your scriptures have anything to do with “end times”. The end times are happening now .. not after the church has left the earth.
If you look at the context of Luke 21:25 Jesus is talking specifically to the disciples about the end times and what will happen immediately before the end times.
Revelation 16 is right at the end, just before Christ returns to set up his rulership on earth.
But besides all that, you miss the point. Maybe the earth isn't warming now, but what if that changes tomorrow? Nobody knows what's going to happen. The argument should be about the SOURCE of climate change. Don't allow acceptance of the faulty Leftist assumption by not addressing it.
