New data on Global Forest Watch shows that in some of the world's most heavily forested nations, more than 90 percent of tree cover loss is happening in natural forests rather than plantations.

These forests, which cover approximately 250 million hectares — more than California and Texas combined — play a critical role in regulating the global climate.

Given current emissions trajectories, there is a chance that the temperature increase by 2100 could be near 6oC.21 The last time Earth exhibited a global mean temperature that high, what are now sagebrush grasslands in the southwestern Wyoming and Utah were covered by subtropical, closed canopy forests interspersed with open woodlands (Townsend et al., 2010), reminiscent of subtropical areas in Central America today.

«Losses or gains in forest cover shape many important aspects of an ecosystem including, climate regulation, carbon storage, biodiversity and water supplies, but until now there has not been a way to get detailed, accurate, satellite - based and readily available data on forest cover change from local to global scales.»

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.
