The study, using complex climate modeling software to simulate changes in forest cover and then measuring the impact on global climate, found that northern forests tend to warm the Earth because they absorb a lot of sunlight without losing much moisture.

Without studying the principles of highly - organized functioning of ecological communities, including their genetically encoded ability to respond to environmental perturbations in a non-random compensatory way, the perspectives drawn from global circulation models with respect to the climatic effects of land cover change (e.g., statements like cutting all boreal forests will ease global warming) will continue to lack any resemblance to reality.

Given that both CO2 and global average temperature are far below the norm for the past 500 million years and primary production in the food chain is also far below the norm then I'd say we probably shouldn't worry about it until we at least have temperate forests covering Antarctica again and the threat of a cold ending to the Holocene Interglacial is not a concern.
