Periods of volcanism can cool the climate (as with the 1991 Pinatubo eruption), methane emissions from increased biological activity can warm the climate, and slight changes in solar output and orbital variations can all have climate effects which are much shorter in duration than the ice age cycles, ranging from less than a decade to a thousand years in duration (the Younger Dryas).

It is to be noted here that there is no necessary contradiction between forecast expectations of (a) some renewed (or continuation of) slight cooling of world climate for a few decades to come, e.g., from volcanic or solar activity variations; (b) an abrupt warming due to the effect of increasing carbon dioxide, lasting some centuries until fossil fuels are exhausted and a while thereafter; and this followed in turn by (c) a glaciation lasting (like the previous ones) for many thousands of years.»

These latter two effects are expected to lead to slight warming, but the overall impact of land use changes is expected to be negative (i.e. a cooling)(Myhre and Myhre, 2003), although the uncertainty is still significant (maybe 0.5 W / m2 either way).

Interestingly, the paper «Climate Trends and Global food production since 1980» (Lobell, Schlenker, Costa - Roberts, in Sciencexpress, 5 May, Science 1204531) confirms my finding of the absence of climate change in the USA: «A notable exception to the [global] warming pattern is the United States, which produces c. 40 % of global maize and soybean and experienced a slight cooling over the period... the country with largest overall share of crop production (United States) showed no [adverse] effect due to the lack of significant climate trends».

So despite over a century of a CO2 - induced warming effect, these other factors helped mitigate this warming effect from about the 1940s to 1970s, resulting in slight global cooling.

Evaporation is a Endothermic process which causes a COOLING effect, so the first stage of H2O absorption MUST causes a slight cooling of the oceans which will offset the slight warming of the initiCOOLING effect, so the first stage of H2O absorption MUST causes a slight cooling of the oceans which will offset the slight warming of the initicooling of the oceans which will offset the slight warming of the initial CO2.

& you seem to be saying CO2 is entirely a COOLING effect, whereas Tallbloke maintains it has a slight warming effect.

Aerosols from volcanic eruptions do have a cooling effect once they reach the stratosphere but the effect of high wind speed in the upper atmosphere would rapidly disperse these, and any local effects would be very slight.

It may be that the slight cooling currently measured around Antarctica today is a consequence of the cooling effects of the ozone hole.

During the late 20th Century the El Ninos has a greater effect on the jet positioning than they do now and the only variable to have changed is the level of solar activity which appears to have coincided with a slight warming of the stratosphere (previously cooling) and an intensification of the inversion at the tropopause which then redirects more energy back downward in the polar high pressure cells.

Re my above comment (# 23)-- I should have stated that volcanic forcing predominantly warms the stratosphere, and has little effect — mainly a slight cooling — on the troposphere due to its ability to reduce the intensity of solar radiation reaching the troposphere and the surface.
