Overvaluing the influence of CH4 emissions on climate could easily result in our «locking» the earth into a warmer temperature trajectory, one that is temporarily masked by the short -
term cooling effects of the CH4 reductions, but then persists for many generations.

The
cooling effect of aerosols can partly offset global warming on a short -

effect.
A similar pace of increases between 2003 and 2006 most certainly did
cool the economy, and the rise in short -

effects of Fed policy on funding costs in global markets) may have precipitated the early days of the subprime ARM crisis, when rates were being adjusted sharply upward, causing payment shock for borrowers.
Could you please define «short
term», so we would know when the anthropogenic greenhouse forcing is expected to trump the recent natural
cooling effects, whatever they may be.
If CO2's
effect on climate has been exaggerated, and the globe is
cooling for the short

cooling, coal can sustain us until alternative energy is widespread.
When the
effects of lateral advection are considered, the magnitude of summer
cooling via mixing (4 kelvin per month) is equivalent to that required to counter the heating
terms.
This is an issue because we know there is a substantial long -
term natural
cooling trend for high - latitude summers because of Earth orbital
effects, but the trend is nearly zero in the global annual average.
Some longer -
term effects may remain after several consecutive eruptions, but even then, the 0.1 K
cooling by volcanic eruptions over the past 600 years (0.3 K modeled over the past 100 years, see fig. 1 on this page) seems rather high...
In
terms of the
cooling effect of clouds, the immediacy of feeling that
effect is due to the blocked incoming radiation from the sun, just as it would be if you stepped beneath a large shade tree.
However, when all of the warming and

term.
fhhaynie For the empirical ice core and proxy temperature data on which the 1000 year cycle is based see Figs 6 and 7 in the latest post at http://climatesense-norpag.blogspot.com Interestingly Fig 6 also suggests that if you believe (which I obviously don't) that CO2 is the main climate driver - its long
term effect is to
cool the earth.
In

effect from the Milankovitch Cycle.
For November to be warmer than the long -
term average in the troposphere, we would have had to see solar output increase over the measurement period (it has not), or sensible or latent heat to be higher than average (it is not, in fact we ware in a ENSO neutral or
cool PDO situation), or we would have to see GH gases having an
effect.
Thus it is entirely unsurprising that these short -
term effects all aligning in the
cooling direction in recent years have offset much of the surface warming caused by human greenhouse gas emissions.
More clouds both drastically reduce energy input from the sun and simply slow release of what energy there is trapped in the lower troposphere, but the long
term effect would be a fall in average temperature because of the significantly reduced input power but the atmosphere's ability to
cool is aided by air current circulation whereby the warmer air rises above those low clouds and that infra - red is more easily re-emitted into space, whereby the low clouds now block that re-emission from hitting the ground again to any significant degree.
The methodology Stevens used to quantify the aerosol
cooling effect was so clever and provocative that a colleague
termed the study an «idea paper.»
The thermometer network is made up of a patchwork of non-research quality instruments that were never made to monitor long -

effect with long -

The second issue raised in our Science paper (now available free, see bottom of this post) is that perhaps there shouldn't yet have been substantial long -

I found it to be in the model ball park (perhaps a bit larger, actually) which implied a large warming bias in the surface data, a large
cooling bias in the satellite data, some less large combination of those two, or an unknown real climactic
effect on lapse rate variation that only operates on the long
term and is absent from current models:
I have long argued for the validity of the
