Carbon dioxide concentrations in our atmosphere recently hit the 400 parts-per-million mark. So is all that CO2 scorching the planet? No. But it does seem to be making our deserts greener.

Listening to the global warming alarmists, one would think that man-made CO2 emissions are threatening the globe. But that's speculation. Let's deal in reality. And the reality, according to Australian research, is that in this era of higher carbon concentrations, plant life in dry regions has grown lush.

The greening of the deserts is due to the "fertilization effect" — the impact carbon dioxide has on plant life.
