Sentences with phrase «stronger land carbon»

If the recent «slowdown» in global surface warming is reversing, the stronger land carbon sink seen in recent years may weaken again, and the rise in CO2 may quicken again.

Not exact matches

It includes 42 recommendations for state action, including calls for stronger regulation of carbon emissions and other land - based pollutants that contribute to acidification.

There's typically an initial ocean uptake as tropical East Pacific upwelling (CO2 degassing) is reduced, followed by a stronger release of carbon from land.

The elements that I believe are key to a successful agreement in Copenhagen include: • Strong targets and timetables from industrialized countries and differentiated but binding commitments from developing countries that put the entire world under a system with one commitment: to reduce emissions of carbon dioxide and other global warming pollutants that cause the climate crisis; • The inclusion of deforestation, which alone accounts for twenty percent of the emissions that cause global warming; • The addition of sinks including those from soils, principally from farmlands and grazing lands with appropriate methodologies and accounting.

The report argues for a strong GEF role in such emerging sectors with high mitigation potential as urban systems combining transport, buildings, water supply, waste treatment, food supply and land use zoning, AFOLU (Agriculture, Forest and Other Land Use), agri - food supply systems — including emerging and often controversial mitigation opportunities such as short - lived climate forcers and carbon capture and storland use zoning, AFOLU (Agriculture, Forest and Other Land Use), agri - food supply systems — including emerging and often controversial mitigation opportunities such as short - lived climate forcers and carbon capture and storLand Use), agri - food supply systems — including emerging and often controversial mitigation opportunities such as short - lived climate forcers and carbon capture and storage.

Big carbon polluters are failing to offer strong, specific plans for land use as part of the pledges they're releasing ahead of the Paris talks, known as Intended Nationally Determined Contributions (INDCs), according to a new report from the Union of Concerned Scientists.

«In our mor recent global model simulations the ocean heat - uptake is slower than previously estimated, the ocean uptake of carbon is weaker, feedbacks from the land system as temperature rises are stronger, cumulative emissions of greenhouse gases over the century are higher, and offsetting cooling from aerosol emissions is lower.

Thawing permafrost also delivers organic - rich soils to lake bottoms, where decomposition in the absence of oxygen releases additional methane.116 Extensive wildfires also release carbon that contributes to climate warming.107, 117,118 The capacity of the Yukon River Basin in Alaska and adjacent Canada to store carbon has been substantially weakened since the 1960s by the combination of warming and thawing of permafrost and by increased wildfire.119 Expansion of tall shrubs and trees into tundra makes the surface darker and rougher, increasing absorption of the sun's energy and further contributing to warming.120 This warming is likely stronger than the potential cooling effects of increased carbon dioxide uptake associated with tree and shrub expansion.121 The shorter snow - covered seasons in Alaska further increase energy absorption by the land surface, an effect only slightly offset by the reduced energy absorption of highly reflective post-fire snow - covered landscapes.121 This spectrum of changes in Alaskan and other high - latitude terrestrial ecosystems jeopardizes efforts by society to use ecosystem carbon management to offset fossil fuel emissions.94, 95,96

However, he added: «Overall, the carbon footprint of air - freighting is greater to such a large degree than land transport that we think there is a pretty strong case for looking at a ban very seriously.»
