The insufficient observational coverage has also been noted by the IPCC AR4 and by Gillett et al. (Nature Geoscience, 2008), who argue that the observed warming in the Arctic and Antarctic are not consistent with internal climate variability and natural forcings alone, but are directly attributable to increased GHG levels.

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.»

And note in addition that in addition to the warming, there are strong trends toward decreasing rainfall across the Antipodean continent, which are backed up by tragically decreased river and stream flows, severe water restrictions in most states (starting to ease in some places due to recent floods), and a significantly increased farmer suicide rate.

Note, this is separate from the highly debated issue of whether global warming has led to a significant increase in Category 4 and 5 hurricanes since the 1970s.

Do you think that in the same way that the Solanki et al paper on solar sunspot reconstructions had a specific statement that their results did not contradict ideas of strong greenhouse warming in recent decades, this (the fact that climate sensitivity projections are not best estimates of possible future actual temperature increases) should be clearly noted in media releases put out by scientists when reporting climate sensitivity studies?

Conversely I note that if CO2 directly causes warming as you appear to be claiming, the fact that ice cores show that temperatures increased about 800 years before a CO2 increase (and a latter decline in temperatures before CO2 levels declined) casts doubt upon CO2 as a driver.

Higher clouds are an expected effect of warming, and to first order, independent of GCRs — see ftp://eos.atmos.washington.edu/pub/breth/papers/2007/Zhu-etal-LowCldClimSens-JGR-2007.pdf Note the increase in high clouds (Fig2b3) and decrease in low clouds (Fig2e1) downwind of S America in the equatorial trade winds..

«While La Niña [conditions in 2011] had a large role to play in the failure of the rains in East Africa, there is evidence that warming in the western Pacific — Indian Ocean warm pool has contributed to an increased frequency of droughts in this region,» the researchers note.

You'll note an acceleration of those temperatures in the late 1970s as greenhouse gas emissions from energy production increased worldwide and clean air laws reduced emissions of pollutants that had a cooling effect on the climate, and thus were masking some of the global warming signal.

I note that Hansen's 1988 predictions are a true test of the most important question in the global warming question — that of what is the climate / temperature sensitivity to increases / doubling of CO2 and other GHGs.

I will note that this is also a very different level of certainty from the «it is likely that increased CO2 will lead to sufficient warming to cause problems for humanity and ecosystems», which I will posit is likely, but if CO2 went up to 600 ppm and temperatures in 2100 only increased by a degree or so, I would be very surprised but would not feel like the laws of physics had been repealed.

Even though some of the CMIP models produce a lot of global warming, all of them are still stable in this regard, with net increases in lost radiation with warming (NOTE: If analyzing the transient CMIP runs where CO2 is increased over long periods of time, one must first remove that radiative forcing in order to see the increase in radiative loss).

«Even if one assumes that the relationships between climatic variables and mortality used in this study are valid,» Goklany concludes, «considering the cumulative effect of the shortcomings noted above, the methodologies and assumptions used by the WHO inevitably exaggerate the future mortality increases attributed to global warming, perhaps several-fold.»

Christy is correct to note that the model average warming trend (0.23 °C / decade for 1978 - 2011) is a bit higher than observations (0.17 °C / decade over the same timeframe), but that is because over the past decade virtually every natural influence on global temperatures has acted in the cooling direction (i.e. an extended solar minimum, rising aerosols emissions, and increased heat storage in the deep oceans).

Note also, having aerosols a cooling means that your relationship between CO2 and temperature in the ice - cores is blown away; dust levels increase by three orders of magnitude going from warming to cooling, and dust changes occur before temperature changes, which occur before CO2 changes.

The very same paper may also make note of CO2's warming influence, and on possible outcomes if atmospheric CO2 continues to increase in the future.

On the matter of global climate change, APS notes that virtually all reputable scientists agree with the following observations: Carbon dioxide is increasing in the atmosphere due to human activity; Carbon dioxide is an excellent infrared absorber, and therefore, its increasing presence in the atmosphere contributes to global warming; and The dwell time of carbon dioxide in the atmosphere is hundreds of years.

«Hulme et al. (2001) noted that throughout the twentieth century, Africa has warmed at a rate of 0.5 °C century − 1 and from 1987 to 1998, the six warmest years in Africa's temperature record occurred with increasing intensity making 1998 the warmest.

Trenberth notes that global warming has already increased the average amount of water vapor in the atmosphere by about 4 %, «extra moisture flowing into the storms that produced the heavy rains and likely contributed to the strength of the storms through added energy.»

The instabilities in the climate system and the movement from global warming to global heating kicks in above 350 ppm, so that as the ppm increase, mitigation opportunities are lost and catastrophic harms on an even grander grand scale (as noted by Mike) will continue to occur to human and other life forms.

In 25 years of global warming hype, why hasn't one article noted that it will increase the number of beach days?

This was the generally accepted idea, but it's important to note that the increase in sea ice extent does not necessarily contradict global warming.

Warming cloud feedbacks — note the large increase in SW forcing — are a small fraction of that at best.

Note 1: A simple hotspot explanation summarized from this article: Increasing CO2 levels causes atmosphere to warm; then atmosphere causes Earth's surface to warm; warming of oceans cause evaporation; increased evaporation leads to more water vapor in the upper troposphere; water vapor is a powerful greenhouse gas that warms the atmosphere even more (positive water vapor feedback); the Earth's surface warms even more; and then auto «repeat and rinse» until Earth's oceans boil, per an «expert.»

What we have just proven is that for any isolated gas, in the absence of a source of external work — note that I do not care in this proof how or why the initial state of the gas with some sort of thermal lapse came about, whether or not there is gravity present or absent, whether or not the gas is a mixture or pure — if we move a dollop of heat from where it is warmer (cooling it) to where it is cooler (warming it) we increase the entropy of the Universe and such a fluctuation in the state of the gas is irreversible.

Note that whenever «warm» proxies drop out it tends to decrease the average immediately after that, and when «cool» proxies drop out there's an increase in the average immediately after that.

You'll note that the dude is clueless («Since surface temperature ncreased significantly from 1976 to 1998, one would expect the deep ocean to warm too, not because it's absorbing additional heat but because of the that increase in surface temperature.

(Note, however, that to the extent that positive cloud feedbacks on GHG - mediated forcing mediate a reduction in cloud cover, the amplification will substitute some SW effects for LW effects due to the reduced cloud greenhouse warming and increased warming from a lower albedo).

As I noted last week, there is a new article in Nature that tries very hard to prove that CO2 increased prior to the warming at the onset of the current interglacial which is known as the Holocene.

Soloman and her co-authors argue that El Niño has been one of the drivers of changes in stratospheric water vapor, noting that «The drop in stratospheric water vapor observed after 2001 has been correlated to sea surface temperature (SST) increases in the vicinity of the tropical «warm pool» which are related to the El Niño Southern Oscillation (ENSO).»

Note that you would have to increase the ocean temperature a lot to get 100 ppm of CO2 as we have in the past century, so we can be sure it is not ocean - warming alone that can account for this (beside the acidification being the wrong sign for the ocean to be the source).

Go look at the following Wikipedia page on the Maunder Minimum starting in about 1645 and lasting about 50 years noting the clear correlation between the minimal sunspot activity at the time with lower temperatures, and then look at the chart there showing the enormous increase in average sunspot activity commencing in about 1945 so just starting in and lasting through the exact same time frame of temperature increases that Warmers especially point to as evidence for their thesis.

Note that the increase near the surface is significantly larger, with most of the warming being in the first 700 meters.

A drying of the atmosphere — that the researchers note — takes place in the subtropical subsidence zone (the 30 degrees latitude) but expands towards the 30 - 45 degrees latitude — Earth's Meditteranean climates, where their model suggests net cloud cover would actually decrease most (see dotted line in first image in this article, at top)-- most notably around 500 hPa (roughly translating to a height of around 5 kilometers of altitude in the troposphere) decreasing albedo and increasing solar heat absorption, therefore net climate warming.
