They cry climate change, but the climate has always regularly changed. If they worry about climate change now, they should really be worried about how MUCH the climate of earth will change when the Tribulation occurs.
In reading Revelation it's like reading a horror story of the world's climate. Grass burned, rivers drying, sun scorching men with heat that is so unbearable, volcanic winters, you name it. Just read Revelation 6-18 to view the upcoming changes to the climate.
Christians know that it will be due to God's transformation of the earth in preparing it for the renewal back to how the earth was before the curse. But the climate change enthusiasts and worriers will surely be declaring "We told you so" all the while repeatedly denying that it is God in charge and making these changes. (Revelation 16:9, 11, 21...)
I found this illustration of earth without water from Physics and Astronomy Zone.
Revelation 11:6 says the Two Witnesses have the power to shut the sky, that no rain may fall during the days of their prophesying, and they have power over the waters to turn them into blood and to strike the earth with every kind of plague, as often as they desire.
No rain for three years? Wow. Crops fail and food becomes scarce, especially for the poor.
Climate change now? Please. They don't know the climate that is about to change horrifically on God's initiation and timing, but they will. As many as we share the Gospel with and who convert, so as to be raptured prior to these changes, there will be many millions left behind that will endure these terrible changes to the climate. It makes me sad, but it must be so. God will be glorified in the many who do come to faith during the prophesied time of Tribulation, in which the earth will groan so loudly that many will fall down and beg,
And said to the mountains and rocks, Fall on us, and hide us from the face of him that sits on the throne, and from the wrath of the Lamb: For the great day of his wrath is come; and who shall be able to stand? (Revelation 6:16-17).
I do not think that the earth will be completely dry during the Tribulation,as in this unrelated rendering from the Twitter stream of Physics and Astronomy Zone, but it's interesting to see how much we do depend on water.
