Not exact matches

The average global sea surface temperature tied with 2010 as the second highest for January — August in the 135 - year period of record, behind 1998, while the average land surface temperature was the fifth highest.

The January global land surface temperature was also second highest on record, while the global ocean surface temperature was third highest.

The former is likely to overestimate the true global surface air temperature trend (since the oceans do not warm as fast as the land), while the latter may underestimate the true trend, since the air temperature over the ocean is predicted to rise at a slightly higher rate than the ocean temperature.

While land surface observations go back hundreds of years in a few places, data of sufficient coverage for estimating global temperature have been available only since the end of the 19th century.

However, the CRU global mean combined land air / sea surface temperature estimates for Jan - Aug 2005 lag behind the 1998 annual mean estimate by 0.08 C (0.50 C vs. 58C for 1998) while GISS indicates a lag of 0.02 C.

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).

The former is likely to overestimate the true global surface air temperature trend (since the oceans do not warm as fast as the land), while the latter may underestimate the true trend, since the air temperature over the ocean is predicted to rise at a slightly higher rate than the ocean temperature.

Over the past century, surface warming over global drylands (1.2 — 1.3 °C) has been 20 — 40 % higher than that over humid lands (0.8 — 1.0 °C), while anthropogenic CO2 emissions generated from drylands (∼ 230 Gt) have been only ∼ 30 % of those generated from humid lands (∼ 750 Gt).

-LSB-...] With satellites, they have collected regional and global measurements of the «greenness» of the land surface and assessed the presence or absence of vegetation, while looking for signals to distinguish trees from shrubs from ground cover.
