On the whole, the Earth's land surface has «greened» in response to rising CO2 emissions and warmer temperatures, but these new results suggest there could also be a negative impact of climate change on vegetation growth in North America.

Berkeley Earth was created to address potential biases in the land surface temperature record.

Ray, I think Lee Grable's point is important: The fact that we use the term «global temperature» to mean the average temperature on a two - dimensional surface rather than the three - dimensional ocean plus land plus atmosphere system of the earth has the potential to allow confusion.

The two longest ones are of temperature near the Earth's surface: a vast network of weather stations over land areas, and ship data from the oceans.

After all, if average surface temperature is 15 C, wouldn't you expect land and ocean below the surface to equilibrate at roughly that temperature (with a slightly rising gradient to account for the flow of Earth's internal heat)?

For those not familiar with it, the purpose of Berkeley Earth was to create a new, independent compilation and assessment of global land surface temperature trends using new statistical methods and a wider range of source data.

The new paper, «A New Estimate of the Average Earth Surface Land Temperature Spanning 1753 to 2011,» has been posted, along with extensive related material, including a list of responses to frequent questions, including these:

My amateur spreadsheet tracking and projecting the monthly NASA GISS values suggests that while 2018 and 2019 are likely to be cooler than 2017, they may also be the last years on Earth with global average land and ocean surface temperature anomaly below 1C above pre-industrial average (using 1850 - 1900 proxy).

Global average temperature is lower during glacial periods for two primary reasons: 1) there was only about 190 ppm CO2 in the atmosphere, and other major greenhouse gases (CH4 and N2O) were also lower 2) the earth surface was more reflective, due to the presence of lots of ice and snow on land, and lots more sea ice than today (that is, the albedo was higher).

But even when carbon dioxide does make its way out of the atmosphere, Earth's natural systems can release other carbon dioxide molecules that were previously stored in the oceans / land back into the atmosphere, making the full effect of carbon dioxide emissions on surface temperatures much longer than this 5 - 200 year average.

As far as I am aware, temperatures of the atmosphere close to the surface, rather than the actual surface, are usually measured over land, unless measured remotely by satellites, in which case the temperature of the material overlaying the Earth's surface is measured, rarely the surface itself.

I also think that if one wishes to prove that carbon dioxide in the atmosphere is the cause of global warming then the focus of temperature measurement should be upon those few feet between the Earth's surface and the measuring instruments employed on land for measuring that temperature.

See Rohde et al., A New Estimate of the Average Earth Surface Land Temperature Spanning 1753 to 2011, Geoinformatics & Geostatistics 2013.

Water takes longer to heat up and cool down than does the air or land, so ocean warming is considered to be a better indicator of global warming than measurements of global atmospheric temperatures at the Earth's surface.

To get a complete picture of Earth's temperature, scientists combine measurements from the air above land and the ocean surface collected by ships, buoys and sometimes satellites, too.

Other GMST series based on land temperature stations and sea surface temperatures from ships and buoys are now available and are regularly updated, such as those from the Japanese Meteorological Agency and Berkeley Earth.

The three major groups calculating the average surface temperature of the earth (land and ocean combined) all are currently indicating that 2014 will likely nudge out 2010 (by a couple hundredths of a degree Celsius) to become the warmest year in each dataset (which begin in mid-to-late 1800s).

This created a qualitative transformation in Homo sapiens» impact on earth system trends: levels of carbon dioxide, nitrous oxide, methane, stratospheric ozone, surface ocean temperature, ocean acidification, marine fish capture, coastal nitrogen, tropical forest depletion, land domestication and terrestrial biosphere degradation.

One result of the Berkeley Earth kriging approach is the construction of a temperature field for the entire land surface, such that every location on the land has an estimated temperature that is a function of latitude, longitude, altitude, climatology, and a residual — or weather.

However, these sites do not provide even or comprehensive coverage of the Earth's surface, nor are the sites immune to contamination from land - use changes — all of which add noise and uncertainty to the world temperature measurements.

Estimates of temperature variations near the earth's surface are based on thermometer readings taken daily at thousands of land stations and on board thousands of ships.

Third, the distribution of land and water on the Earth's surface; which controls its temperature distribution, moisture availability, monsoon effects, hurricanes, and other storm tracks.
