Global heating only a start?

Revelation 16:8 And the fourth angel poured out his vial upon the sun; and power was given unto him to scorch men with fire. 9 And men were scorched with great heat, and blasphemed the name of God, which hath power over these plagues: and they repented not to give him glory.

No wonder that we read in Isaiah 2 that people hide in the caves:
Isaiah 2:19 And they shall go into the holes of the rocks, and into the caves of the earth, for fear of the LORD, and for the glory of his majesty, when he ariseth to shake terribly the earth.

Global heating now is warning us that the Lord might arise soon to start to shake the earth.

Now it is only a difference in temperature of a few degrees.

How terrible it will be when men is scorched by the heat of the sun in tribulation time.

And then we read they still did not repent!

Now is still the time of mercey, the time to repent.
Don't wait! You might not be able lateron.

Very serious times ahead.
