The Earth is the Lord's: Al Gore and the Climate Crisis

Have you heard the story of the two planets? Both are about the same size and both contain roughly the same total concentration of carbon dioxide. One has an average daily temperature of 833 degrees Fahrenheit, while the other averages 59 degrees. And humans can live only on one of these two planets: Earth. Venus, on the other hand, is inhospitable because most of the carbon dioxide resides in the atmosphere. And incidentally, Mercury is much closer to the sun than Venus, yet has average temperatures in the 300 degree range - thanks to lower levels of carbon dioxide.

"The earth is the Lord's, and the fullness thereof," former Vice-President Al Gore quoted from Psalm 24:1 as he gave a special, scripture-saturated presentation of his well known slideshow-turned-movie, An Inconvenient Truth.

The 2500 Baptists attending the Gore luncheon during the New Baptist Covenant Celebration witnessed a solid biblical argument for why Christians must be concerned about God's creation.

Overwhelming scientific evidence has revealed that humans are severely damaging God's creation, and now the discussion is whether or not humans will destroy both God's earth as well as the whole of humanity. Thankfully, most evangelicals today now understand that God's creation is teetering on the brink of disaster. In our corner is Baptist layman Al Gore, whose tireless and highly visible advocacy on behalf of God's creation is motivating people worldwide. He is passionate, has a great sense of humor, and believes that "the earth is the Lord's" and that humans have a responsibility to be good stewards of that which is Gods. And 2500 Baptists just gave him a standing ovation.

Tonight Venus will be visible in the night sky. Take a hard look at it. Atmospheric carbon dioxide makes it a death star. And that could be the future of the earth, unless we as Christians take the Bible seriously enough to invest ourselves in the care of God's creation.

That is right....the Earth is the Lords and the fullness thereof. It belongs to him and he knows how to take care of it. There are many scientists who prove that global warming is false. There is a hidden agenda behind the whole farce.

But of course it is not just climate change, it is pollution of many sorts, over-fishing, deforestation, unsustainable living standards in the developed world,inadequate recycling of toxic and non-biodegradable materials. I grew up being taught that God helps those who help themselves; if we do not care enough about our world to care for it properly, I do not suppose much help will be forth coming.

Venus isn't hot because it's 97% CO2, it's hot because it's atmosphere is 90 times the mass of Earth's.

(Note, any greenhouse gases will do. On Earth, it's mostly water vapour.)

The fundamental problem here is that the Warmenistas have been lying about how the Greenhouse Effect is supposed to work. It doesn't work by trapping infra-red, it works because of pressure.

First, when you compress air, it gets hot, and when you let it expand, it cools. This results in the air cooling with altitude - for every 6 km you go up, it cools by 1 degree C. Second, the heat coming in has to balance the heat going out, and the heat radiates out at the 'top' of the atmosphere, where the air above is too thin to stop it escaping any more. To maintain heat balance, the top of Earth's atmosphere must be at about -20 C on average, and the increase of temperature with pressure means that the surface is about 34 C warmer, or about 14 C (global average). Doubling CO2 raises the height of the 'top' of the atmosphere about 150 m, and hence warms the surface about 1 C. (This is then claimed to be trebled by feedbacks.)

Venus has a thicker atmosphere, so instead of the effective top being 5 km up (it's actually spread over the bottom 10 km fairly evenly on Earth), it's about 50-60 km up. And with no water, it increases about 10 C per km, meaning the surface is 500-600 C warmer than the cloud tops. Actually, the cloud tops are at about the same temperature and pressure as Earth's surface (it's even been proposed that colonists could live there in balloons), and the 'top of atmosphere' temperature where it radiates to space is about 30 C cooler (!) than Earth's, because of the higher albedo of Venus. Hence, the surface is very hot.

Simple physics, and no 'runaway' necessary.
