Is It Warm in Here? Another story on irreparable climate change

from Lovelock to Lovejoy.

How curious!

Another ecoscientist this time American thinks it may be too late for the planet.
The writer thinks that Americans are unlikely to notice till it is too late, if it is not so already.

Is It Warm in Here?: "Lovejoy fears that changes in the Amazon's ecosystem may be irreversible. Scientists reported last month that there is an Amazonian drought apparently caused by new patterns in Atlantic currents that, in turn, are similar to projected climate change. With less rainfall, the tropical forests are beginning to dry out. They burn more easily, and, in the continuous feedback loops of their ecosystem, these drier forests return less moisture to the atmosphere, which means even less rain. When the forest trees are deprived of rain, their mortality can increase by a factor of six, and similar devastation affects other species, too.

'When do you wreck it as a system?' Lovejoy wonders. 'It's like going up to the edge of a cliff, not really knowing where it is. Common sense says you shouldn't discover where the edge is by passing over it, but that's what we're doing with deforestation and climate change.'"
