There is going to be a day of Global Warming---but not like that preached by the Green Religion...
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.
Revelation 16:9
It will not be caused by man.....
...and the light of the sun shall be sevenfold, as the light of seven days,
Isaiah 30:26
