I find the BC declines a bit unexpected (for me at least), as I thought increased Chinese emissions were overwhelming other reductions.

The latest analysis by the Netherlands Environmental Assessment Agency, described at the Green blog and Roger Pielke Jr.'s blog, shows how the decline in per - capita emissions from the deep recession was overcome by growth in the industrializing world.

For example, if energy demand will quadruple in the next 70 years while emissions must decline to near zero, then we need to develop and deploy at scale energy technologies that have near zero emissions.

James Murdoch, the young scion of the giant News Corporation media empire, has an op - ed article for The Washington Post aimed at «conservation - minded conservatives,» spelling out the many reasons to propel an energy transformation in the United States through a declining cap on carbon dioxide emissions, despite the uncertainties in climate science.

In general, so long as there is some solar heating beneath some level, there must be a net LW + convective heat flux upward at that level to balance it in equilibrium; convection tends to require some nonzero temperature decline with height, and a net upward LW flux requires either that the temperature declines with height on the scale of photon paths (from emission to absorption), or else requires at least a partial «veiw» of space, which can be blocked by increasing optical thickness above that level.

It shows a (modeled) decline from today's (well, 2015's) emissions, which they put at ~ 11,000 Mt CO2e, to well under 1,000 in 2035, and zeroing out completely between 2045 and 2050.

To understand emissions reductions necessary to have a good chance of limiting warming to 2 °C, the climate community has focused largely on emissions pathways — that is, when greenhouse gas emissions peak and the rate at which they must decline (e.g. peak sooner and then reduce less steeply versus peak later and then reduce more steeply).

Flatly assuming that human CO2 emissions are going to continue at the same exponential rate when human population growth is expected to decline sharply to one - fourth the past rate is stupid.

One of the central criticisms aimed at the infamous Great Global Warming Swindle, for example, is precisely that it failed to entertain the idea that the post-1940 decline in global temperatures was the result of increases in sulphurous emissions that masked the forcing effect of rising atmospheric CO2.

It should be mentioned, though, that RCP 2.6 seems extremely optimistic at present, as the decline in emissions initially is very steep, and after 2070 or so, humankind is projected not only to not be emitting any CO2, we are also projected to be actively removing CO2 from the atmosphere!

In «high income regions» (OECD90, REF) sulfur emissions have already passed their peaks and are actually declining at present.

There are plenty, but for a conservative example see IPCC Synthesis Report 2007 Table 5.1 which says to stay within 2 - 2.4 degrees global average temperature increase above pre-industrial (Copenhagen upper «low risk» target) and 425 - 490ppm CO2 - equivalent concentration at stabilisation, the required change in global CO2 emissions in 2050 (percent of 2000 emissions) is decline between 85 to 50 percent.

We will need to see a deep decline if we are to limit dangerous climate change, and even with existing emissions - reduction commitments, global emissions are not expected to decline until at least after 2030.

Why aren't we dropping all this academic formality and moving at light speed to decline our carbon emissions to zero?

CO2 emissions from fossil fuel combustion in France and Belgium both declined at 3.7 % on average between 1978 - 1988 following the oil crisis of the 1970s: http://www.nature.com/nclimate/journal/v3/n1/full/nclimate1783.html#supplementary-information

This emissions decline was the largest in any year that had positive growth in per capita gross domestic product (GDP)-- its economic output — and the only drop when GDP rose at least 2 %.

The «initial strategy» aims to peak and decline shipping greenhouse gas (GHG) emissions as soon as possible, and to reduce them by «at least» 50 % by 2050 compared to 2008 levels.

Because this global challenge can only be met by a global response, we reiterate our willingness to share with all countries the goal of achieving at least a 50 % reduction of global emissions by 2050, recognizing that this implies that global emissions need to peak as soon as possible and decline thereafter.

Queensland is destroying tree cover at the rate of 10 square kilometres a day, harming biodiversity while stoking doubts about federal data suggesting emissions from land clearing are in decline.

Its reference case, based on federal policies on the books at the end of 2014, forecast that emissions of carbon dioxide from energy use (the United States» main source of greenhouse gases) would not decline but remain flat through 2025 and beyond.

This limited range of pathways all have a rate of warming less than 0.2 °C per decade, which initially suggests that a cumulative emissions target could be used to constrain rates of warming, assuming that rates of decline are kept at less than 4 per cent per year.
