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).

Projected temperature and precipitation increases may be favorable in the short term for some Montana crops and forage production, but the effects of warming will become increasingly disruptive as they accelerate beyond adaptation thresholds.

Current state - of - the - art climate models predict that increasing water vapor concentrations in warmer air will amplify the greenhouse effect created by anthropogenic greenhouse gases while maintaining nearly constant relative humidity.

UHI effects have been documented in city environments worldwide and show that as cities become increasingly urbanised, increasing energy use, reductions in surface water (and evaporation) and increased concrete etc. tend to lead to warmer conditions than in nearby more rural areas.

Direct effects of climate change on trees and forests, such as warmer, wetter conditions improving forest productivity or warmer, drier conditions increasing tree mortality, will be secondary to the impacts of altered forest disturbance regimes, such as changes in forest fire behavior and area burned.

If potentially pernicious effects such as global warming are human - driven, then it is reasonable and sensible to ask what is fueling the recent skyrocketing increase of absolute global human population numbers that, in turn, are destabilizing Earth's global ecosystems and dissipating Earth's limited resources in our time.

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

What causes doubt and confusion is that the effects of global warming are not uniform around the globe and there are always weather fluctuations (that may even increase in scale and predictability) as global warming progresses.

If you believe the warming is natural, first please explain why the increases in CO2 isn't having the effect our knowledge of physics tells us it will have.

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.»

CO2 emissions in particular continue to increase at a rapid rate; ii) the effect of these gases is to warm the climate and it is very likely that most of the warming over the last 50 years was in fact driven by these increases; and iii) the sensitivity of the climate is very likely large enough that serious consequences can be expected if carbon emissions continue on this path.

By the way, low clouds in darkness increase surface temperature, sort of like the inverse property of commonly understood Cosmic ray effect, not causing a cooling because there are more CR's, but rather a warming, which only low clouds in total darkness can do, so the probable CR temperature signal gets cancelled from one latitude dark vs bright region to the next.

That's a hypothesis and, arguably, a reasonable ASSOCIATION, but cause and effect has hardly been established, and I understand it's not clear whether global warming causes an increase in CO2, or vice versa.

Later they say «An increase in global temperature is predicted to worsen the effect, since warmer waters hold less gas.»

In the remainder, such increases were mostly unrelated to warming or drying trends and therefore may be due to other climate effects not explored (e.g. lightning ignitions) or possible anthropogenic influences.

A global warming phenomenon in our spaceship is one of several unintended effects of the unregulated, swift increase of 1) absolute global human population numbers, 2) per capita consumption of limited resources, and 3) large - scale business activities that could be occurring synergistically and approaching a point in history when it will not be possible for the Earth's resource base and frangible ecosystems services to sustain life as we now know it to be.

Warming of the oceans leads to increased vertical stratification (decreased mixing between the different levels in the oceans), which would reduce CO2 uptake, in effect, reducing the oceanic volume available to CO2 absorption from the atmosphere.
