Not exact matches

Richard Betts, head of climate impacts at the Hadley Centre of the U.K.'s Met office presented to reporters in Copenhagen today a new analysis of modeling data showing how conserving tropical forests is going to be crucial if the world is to make a target of 2 ˚C, even under the most conservative projections of how much carbon the forests contain.

«What we found was this really strong impact — air that traveled over a lot of forest brought a lot more rain than air that didn't travel over very much forest,» said lead author Dominick Spracklen of the University of Leeds.

That animal's 1990 listing as threatened in the forests of Washington, Oregon and California impacted logging, in much the same way that a similar listing for the grouse could impact ranching, farming and energy development in those three states, as well as Nevada, Colorado, Utah, Idaho, Montana and Wyoming.

«Our study suggests... [the] initiative will not significantly reduce deforestation in northern Sumatra and will have little impact on orangutan conservation,» David Gaveau of the University of Kent, UK, and the Wildlife Conservation Society Indonesia Program told environmentalresearchweb, «because firstly a large amount of forest inside the proposed REDD project area is protected de facto by being inaccessible; and secondly much of northern Sumatra's lowland forests will remain outside of REDD and will be exposed to the combined expansion of high - revenue oil palm plantations and road networks.»

Craig Allen knows as much as anybody about the impact of AGW on forest ecosystems globally.

Regionally however, it is well established that the magnitude of the individual effects varies significantly giving forests an overall climate impact that is very much location dependent.

Surprisingly, replanting with fast - growing pine plantations worsens the CO2 impact of wood because managed plantations do not sequester as much carbon as natural forests.

But without considering the impact of insects, they say, scientists may be overestimating how much carbon dioxide forests will absorb and store in the future.

Maybe I should have added that if Anastassia is correct, doubling CO2 could cause so much growth in our forests that this could have a major impact on climate.

Researchers can now find out just how much climate change can impact the Earth's trees and other plant life in the future by conducting computer simulations on a three - dimensional forest.

Deforestation is as much an issue of poor forest governance — the processes, policies, and laws by which decisions that impact forests are made — as it is an issue of misaligned economic incentives.

Abstract: An evaluation of analyses sponsored by the predecessor to the U.K. Department for Environment, Food and Rural Affairs (DEFRA) of the global impacts of climate change under various mitigation scenarios (including CO2 stabilization at 550 and 750 ppm) coupled with an examination of the relative costs associated with different schemes to either mitigate climate change or reduce vulnerability to various climate - sensitive hazards (namely, malaria, hunger, water shortage, coastal flooding, and losses of global forests and coastal wetlands) indicates that, at least for the next few decades, risks and / or threats associated with these hazards would be lowered much more effectively and economically by reducing current and future vulnerability to those hazards rather than through stabilization.

While scientists have long understood the carbon storing potential of tropical peatland forests — they lock up to five times more carbon than tropical forests and account for a third of the world's total carbon reserves — much less is known about the actual amounts of carbon stored in their soils and the impacts of unsustainable land - use practices.

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.

Also unclear is just how much biomass would have to be turned into biochar to make a meaningful dent in global warming, and what environmental and social impacts this might have — for example, by encouraging the clear - cutting of forests and their replacement by plantations of trees destined for biochar production.

While deforestation has been the focus of most research into forests» effects on climate change, with a recent study suggesting tropical forests are turning into carbon sources rather than carbon stores as a result, the impact of warming soils has remained much of a mystery.
