A 2011 study by the Lawrence Berkeley National Laboratory suggests China's emissions could peak at 9.7 gigatonnes if the government implements ambitious climate policy, the New York Times reports.

Not exact matches

A new report published today by researchers from Imperial College London and the University of Sheffield shows that global carbon emissions could be cut by one gigatonne per year (3 % of global emissions) in less than five years if other countries followed the same strategy.

«Unfortunately, if we add up human emissions from the pre-industrial age to the present, then around 2000 gigatonnes out of the 5000 total have already been released into the atmosphere — so the situation is worrying,» explains Finnish Meteorological Institute researcher Antti - Ilari Partanen, who is currently carrying out research at Concordia University and was involved in the study.

If we wind up emitting an extra gigatonne [billion metric tons] of CO2 into the atmosphere this year, it commits the Earth to a certain amount of additional warming that can't be taken back — a warming that starts to emerge within decades but will still be with us after thousands of years.

On the other hand, if you realize that new growth takes up about 450 gigatonnes of CO2 or about 123 gigatonnes of carbon every year, you might realize that a small improvement (1 - 2 % in the net) could make a significant impact on the increase of CO2 in the atmosphere.

It's a big job, but it's one that has to be done anyway, since if the whole world tries to pull itself into prosperity by burning carbon at the rate the US does, then we run out of coal even at the highest estimates by 2100, and you wind up with no fossil energy and the hellish climate you get from 5000 gigatonnes cumulative emission.

If, that is, we're still to keep within the 2010 — 2050 budget of 420 gigatonnes CO2.

If you have data on the levels each side of the best guess 160 gigatonne sink / source, please write a paper.

Yet even if the high price of energy from fossil fuels and power plants combines with regional climate initiatives to slow the current rate of growth somewhat, we will probably hit 11 gigatonnes of carbon emissions per year by 2020.

The fresh research has provided estimates that if only carbon dioxide emissions are considered then the total carbon dioxide budget that would keep warming below two degrees would be around 5000 gigatonnes.

We'd prefer a return to that stability rather than an uncontrolled experiment in what would happen to biospheric system services of value to humans if we keep pumping multiple gigatonnes of new CO2 into the atmosphere and the oceans.

The UNEP report found that even if nations meet their current climate pledges, ghg emissions in 2020 are likely to be 8 to 12 gigatonnes of CO2 equivalent (GtCO2e) above the level that would provide a likely chance of remaining on the least - cost pathway.

Obviously, if all these countries, led by Argentina, would send their pledges to the UNFCCC, that would make an important contribution to closing the gigatonne gap, as ECO learned from a presentation by AOSIS, showing that also developing countries have a contribution to make in the fight against the gap.

This report, which is unfortunately based on current science (unfortunately because current science is pretty terrifying) begins by noting that we have a mere 565 Gigatonnes of CO2 left in our shared planetary 2000 to 2050 carbon budget, if we intend to maintain a high probability (80 %) of holding the warming below 2C.

«To put this in context, we need 11 gigatonnes of reductions if we are to keep global warming in check.
