These rising atmospheric greenhouse gas concentrations have led to an increase in global average temperatures of ~ 0.2 °C decade — 1, much of which has been absorbed by the oceans, whilst the oceanic uptake of atmospheric CO2 has led to major changes in surface ocean pH (Levitus et al., 2000, 2005; Feely et al., 2008; Hoegh - Guldberg and Bruno, 2010; Mora et al., 2013; Roemmich et al., 2015).

Because climate systems are complex, increases in global average temperatures do not mean increased temperatures everywhere on Earth, nor that temperatures in a given year will be warmer than the year before (which represents weather, not climate).

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

Narrowly scoped, the present situation is either strictly caused by solar variations (in which case I believe the «solar variation» crowd will inappropriately gain credibility over the next 10 to 20 years as we work through the next below average solar cycle or two), or strictly caused by CO2 concentrations (in which case I believe the «CO2 concentrations» crowd will inappropriately lose credibility as the non-linear relationship (sensitivity is based on doublings, not linear increases) between increased CO2 concentrations, and forecasts for below average solar cycles reduces the longer term upward trend in global temperatures).

The addition says many climate models typically look at short term, rapid factors when calculating the Earth's climate sensitivity, which is defined as the average global temperature increase brought about by a doubling of CO2 in the atmosphere.

The real forecast is 383 ppm rising at 2 ppm / year, a minimum carbon dioxide sensitivity to doubling of 3 C, adding positive feedbacks, some of which are unknown, yields a 5 C increase in global average temperatures by 2100, and of course, time does not stop in 2100.

b. All nations agreed to limit the increase in global average temperatures to «well below 2 °C above pre-industrial levels» — the level beyond which scientists believe the Earth will likely begin to experience rapid global warming and to «pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels», a warming amount which may also cause serious global harms particularly to many poor, vulnerable nations.

I'm very convinced that the physical process of global warming is continuing, which appears as a statistically significant increase of the global surface and tropospheric temperature anomaly over a time scale of about 20 years and longer and also as trends in other climate variables (e.g., global ocean heat content increase, Arctic and Antarctic ice decrease, mountain glacier decrease on average and others), and I don't see any scientific evidence according to which this trend has been broken, recently.

The period of increased warming from 1987 to 1997 loosely coincided with the divergence of the global average temperature anomalies over land, which are derived from observation station recordings, and the global average anomalies in sea surface temperatures.

Despite these reclassifications, the general conclusions are similar from previous work: (1) global temperature anomalies for each phase (El Niño, La Niña, and neutral) have been increasing over time and (2) on average, global temperatures during El Niño years are higher than neutral years, which in turn, are higher than La Niña years.

Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gasses, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth.

In any case, the impact estimates that I presented in my previous post were based on the worst case (A1FI) scenario which, according to the HadCM3 model, would increase CO2 concentrations to 810 ppm in 2085 and 970 ppm in 2100, and cause a 4 °C increase in average global temperatures between 1990 and 2085.
