Your life is at steak.

Remember Mr Pachauri? He wanted us to stop eating red meat to save the earth. Meat comes from cows that burp methane. Methane is making the world bake. So meat is bad for the climate.

But now, a study in the Archives of Internal Medicine suggests another solution to the global warming problem. According to the study results, high intakes of red meat may increase the risk of mortality. Thus, red meat can cause early death. And remember, one human less is one human carbon footprint less.

So now, we just need to do some math. What’s better for the planet? To eat methane-burping cows and die prematurely, or to live long enough to make up for all that lost methane by higher CO2-emissions? Any volunteers?

The Guardian tells us today that world CO2 levels have reached a record high. Scientists at the Mauna Loa observatory in Hawaii say that CO2 levels in the atmosphere now stand at 387 ppm, the highest for at least the last 650,000 years.

CO2 is accumulating in the atmosphere faster than expected. The annual mean growth rate for 2007 was 2.14 ppm – the fourth year in the past six to see an annual rise greater than 2ppm. From 1970 to 2000, the concentration rose by about 1.5 ppm each year, but since 2000 the annual rise has leapt to an average 2.1ppm.

But now comes the big question. With the CO2 levels soaring, why won’t the temperatures rise? There is something rotten with this global warming…

Climate scientist Jimbo Hansen at NASA has just drafted a fresh paper urging us to return the CO2-levels back to those of 1988 (350ppm).

Humanity today, collectively, must face the uncomfortable fact that industrial civilization itself has become the principal driver of global climate. If we stay our present course, using fossil fuels to feed a growing appetite for energy-intensive life styles, we will soon leave the climate of the Holocene, the world of human history. The eventual response to doubling pre-industrial atmospheric CO2 likely would be a nearly ice-free planet.

The stakes, for all life on the planet, surpass those of any previous crisis. The greatest danger is continued ignorance and denial, which could make tragic consequences unavoidable.

Sounds to me more like sermon than science. I wonder if Hansen at all believes returning to 1988-levels of CO2 is possible with emissions pouring out of China and India. Someone should tell the guy to get a grip.
