The global mean temperature rise of less than 1 degree C in the past century does not seem like much, but it is associated with a winter temperature rise of 3 to 4 degrees C over most of the Arctic in the past 20 years, unprecedented loss of ice from all the tropical glaciers, a decrease of 15 to 20 % in late summer sea ice extent, rising sealevel, and a host of other measured signs of anomalous and rapid climate change.

Third, using a «semi-empirical» statistical model calibrated to the relationship between temperature and global sea - level change over the last 2000 years, we find that, in alternative histories in which the 20th century did not exceed the average temperature over 500-1800 CE, global sea - level rise in the 20th century would (with > 95 % probability) have been less than 51 % of its observed value.

Although some earlier work along similar lines had been done by other paleoclimate researchers (Ed Cook, Phil Jones, Keith Briffa, Ray Bradley, Malcolm Hughes, and Henry Diaz being just a few examples), before Mike, no one had seriously attempted to use all the available paleoclimate data together, to try to reconstruct the global patterns of climate back in time before the start of direct instrumental observations of climate, or to estimate the underlying statistical uncertainties in reconstructing past temperature changes.

On the possibility of a changing cloud cover «forcing» global warming in recent times (assuming we can just ignore the CO2 physics and current literature on feedbacks, since I don't see a contradiction between an internal radiative forcing and positive feedbacks), one would have to explain a few things, like why the diurnal temperature gradient would decrease with a planet being warmed by decreased albedo... why the stratosphere should cool... why winters should warm faster than summers... essentially the same questions that come with the cosmic ray hypothesis.

[Response: I suspect another common confusion here: the abrupt glacial climate events (you mention the Younger Dryas, but there's also the Dansgaard - Oeschger events and Heinrich events) are probably not big changes in global mean temperature, and therefore do not need to be forced by any global mean forcing like CO2, nor tell us anything about the climate sensitivity to such a global forcing.

For instance, in your scenario of a 20 - yr temperature change of 0.3 ºC + / - 0.18 ºC, assuming a natural noise level (observed standard deviation of detrended annual global temperatures from 1977 - 2004) of 0.085 ºC, a statistically significant difference in the trend that leads to the lowest end of your range (a change of 0.12 ºC) and the trend that leads to the highest end of your range (0.48 ºC) doesn't begin to rise above the level of noise until around year 16 or 17.

Terrell Johnson, reporting on a recent NASA publication concluding that deep ocean temperatures have not increased since 2005 (http://www.weather.com/science/environment/news/deep-ocean-hasnt-warmed-nasa-20141007): «While the report's authors say the findings do not question the overall science of climate change, it is the latest in a series of findings that show global warming to have slowed considerably during the 21st century, despite continued rapid growth in human - produced greenhouse gas emissions during the same time.»

ie does a slightly lower density of air mean a slightly lower ground level temperature (temperature normally decreases with height at the lower air density), so that in reality adding CO2 and subtracting more O2 actually causes miniscule or trivial global COOLING, and the (unused) ability of the changed atmosphere to absorb radiation energy and transmit it to the rest of the air is overruled or limited by the ideal gas law?

Why don't you take up an earlier suggestion from Ross McKitrick and endorse (in summary here) that GHG emissions be taxed proportional to the actual global temperature change?

Responses to the question: «Do you think human activity is a significant contributing factor in changing mean global temperatures?»

The standstil of global average temperature predicted by the «improved» modell compared to warming predicted from the «old» modell is nothing that happens in the future, it should have happened (but did not happen) in the past, from 1985 to 1999: The «improved» modell (green graph) shows that the global average temperature did not change from 1985 (= mean 1980 - 1990) to 1999 (= mean 1994 to 2004).

But it does say; «Natural climate variations, which tend to involve localized changes in sea surface temperature, may have a larger effect on hurricane activity than the more uniform patterns of global warming...»

But the evidence shows this can't be true; temperature changes before CO2 in every record of any duration for any time period; CO2 variability does not correlate with temperature at any point in the last 600 million years; atmospheric CO2 levels are currently at the lowest level in that period; in the 20th century most warming occurred before 1940 when human production of CO2 was very small; human production of CO2 increased the most after 1940 but global temperatures declined to 1985; from 2000 global temperatures declined while CO2 levels increased; and any reduction in CO2 threatens plant life, oxygen production, and therefore all life on the planet.

When the IPCC claimed that the GCM models (with GHG forcing included) could replicate the observed changes in global average temperatures do you know if they were referring to a truly global measurement or were they just using the US temp record?

There can not be any accurate calculations regarding what the temperature impact of UK decarbonization might be, simply because we do not know what role CO2 plays, if any, in global change.

First, I have read all I can on the subject, and I can find no - one who can explain, in detail, why global surface temperatures change in the way that they do.

I have looked at the physics that claims that this can be done, and I am as certain as I can be that there is no proper physics that allows us to even estimate, let alone measure, how much global temperature changes as a result of a change in radiative forcing.

These differ from the glacial - interglacial cycles in that they probably do not involve large changes in global mean temperature: changes are not synchronous in Greenland and Antarctica, and they are in the opposite direction in the South and North Atlantic.

While a global temperature metric for the near - surface tropospheric temperatures is awkward in that it does not account for changes in local climates, it is useful from the most important and broad perspective... as one more metric to indicate total energy flow in and out of the Earth system.

Due to the important role of ozone in driving temperature changes in the stratosphere as well as radiative forcing of surface climate, several different groups have provided databases characterizing the time - varying concentrations of this key gas that can be used to force global climate change simulations (particularly for those models that do not calculate ozone from photochemical principles).

In my earlier posting, I tried to make the distinction that global climate change (all that is changing in the climate system) can be separated into: (1) the global warming component that is driven primarily by the increase in greenhouse gases, and (2) the natural (externally unforced) variability of the climate system consisting of temperature fluctuations about an equilibrium reference point, which therefore do not contribute to the long - term trenIn my earlier posting, I tried to make the distinction that global climate change (all that is changing in the climate system) can be separated into: (1) the global warming component that is driven primarily by the increase in greenhouse gases, and (2) the natural (externally unforced) variability of the climate system consisting of temperature fluctuations about an equilibrium reference point, which therefore do not contribute to the long - term trenin the climate system) can be separated into: (1) the global warming component that is driven primarily by the increase in greenhouse gases, and (2) the natural (externally unforced) variability of the climate system consisting of temperature fluctuations about an equilibrium reference point, which therefore do not contribute to the long - term trenin greenhouse gases, and (2) the natural (externally unforced) variability of the climate system consisting of temperature fluctuations about an equilibrium reference point, which therefore do not contribute to the long - term trend.

«With global temperatures hitting a new record high and repeated episodes of severe weather, including flooding in this country, helping people to understand the basic science behind climate change as well as the consequences for our nature, our businesses and food supply feels like an important thing to do.»

This is done by scaling local to global warming and by «coupled linkages» that show how other climate changes, such as alterations in the water cycle, scale with temperature.»

Not only has the IPCC done remarkably well in projecting future global surface temperature changes thus far, but it has also performed far better than the few climate contrarians who have put their money where their mouth is with their own predictions.

Do you think human activity is a significant contributing factor in changing mean global temperatures?»

Nor does it seem a coincidence that shifts in ocean and atmospheric indices occur at the same time as changes in the trajectory of global surface temperature.

This is because, from the discussion above, we would expect to see sea level changes, since global temperatures do seem to have changed over the last century (whether the temperature trends are man - made or natural in origin).

Given that there is still much we do not know about climate change — including why mean global temperature has been flat for the past ten years — undermining confidence in climate science can (further) undermine its ability to inform policy.

The long - term trend of TSI is most probably caused by a global temperature change of the Sun that does not influence the UV irradiance in the same way as the surface magnetic fields.

The people in charge of the surface stations and the data adjusters don't seem to understand that from a perspective of the climate history having any real utility in indicating a «global temperature trend» their sensors need to report the same values regardless of a change in technology.

They correctly identify, as well, a 2009 survey of 3,146 earth scientists that asked the question, «Do you think human activity is a significant contributing factor in changing mean global temperatures?»

Those who support the theory of anthropogenic global warming (AGW), now known as anthropogenic climate change so that recent cooling can be included in their scenario, always deny that the sun has anything to do with recent global temperature movements.

Policy - makers did not much care about the average global temperature — they wanted to know how things would change in their own locality.

Mr. Dickson wrote passionately about several areas in climate science that troubled him, including: first, the idea that 97 percent of climate scientists agree that climate change is real, caused by humans, and a threat; second, the idea that government agencies had manipulated temperature records to fit a narrative of warming; and third, that China is developing its coal resources so fast that nothing short of radical population control will save us, if burning fossil fuels really does cause global warming.

This is not some «climate science nobody who doesn't know what he is doing» putting stuff together as they like to claim, this is NOAA hoist by their own published data which shows that they have changed the 1997 global Temperature (not just USA) by over 2 degrees C (4 degrees F) in 17 years of adjustments.

Measuring the temperature difference from one year to another in a single location has nothing to do with climate change on a global basis.

As a consequence of the lack of standardization and the inherent difficulties involved in gathering data from remote locations, the best we can do estimating the global mean temperature (against which we estimate change) is 14 ± 0.7 °C or between about 56 and 58 °F 7 — thus our margin of error is greater than our estimate of change.

As I mentioned previously, the recent IPCC report has plenty of detractors and failed to mention the issue of melting methyl hydrates and methane emissions from melting permafrost, over strong objections, which the June, 2013 IEA - WEO follow - up climate change report did include when it forecast a 3.6 - 5.3 degree Celsius jump in average global temperatures by 2100.
