Sentences with phrase «land temperatures over the period»

This is close to the warming of 1.09 °C (0.86 — 1.31 °C) observed in global mean land temperatures over the period 1951 — 2010, which, in contrast to China's recorded temperature change, is only weakly affected by urban warming influences.

Not exact matches

Global mean temperatures averaged over land and ocean surfaces, from three different estimates, each of which has been independently adjusted for various homogeneity issues, are consistent within uncertainty estimates over the period 1901 to 2005 and show similar rates of increase in recent decades.

Animation 1 compares the GISS land surface air temperature trends to UAH lower troposphere temperature trends over land for the period of 1979 to 2012.

That land changes over this period may have slightly increased temperature, and has had regional affects upon climate, and multitude undefined possible effects.

The temperature at each land and ocean station is compared daily to what is «normal» for that location and time, typically the long - term average over a 30 - year period.

Over the same period, the globally and annually averaged land and sea surface temperature (HadCRUT3) increased by 0.7 °C.

The fact this is seemingly not fully recognized — or here integrated — by Curry goes to the same reason Curry does not recognize why the so called «pause» is a fiction, why the «slowing» of the «rate» of increase in average ambient global land and ocean surface air temperatures over a shorter term period from the larger spike beyond the longer term mean of the 90s is also meaningless in terms of the basic issue, and why the average ambient increase in global air temperatures over such a short term is by far the least important empirical indicia of the issue.

However, over long time periods, the variation of the global average temperature with CO2 concentration depends on various factors such as the placement of the continents on Earth, the functionality of ocean currents, the past history of the climate, the orientation of the Earth's orbit relative to the Sun, the luminosity of the Sun, the presence of aerosols in the atmosphere, volcanic action, land clearing, biological evolution, etc..

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.

«The combined average temperature over global land and ocean surfaces for July 2015 was the highest for July in the 136 - year period of record, at 0.81 °C (1.46 °F) above the 20th century average of 15.8 °C (60.4 °F), surpassing the previous record set in 1998 by 0.08 °C (0.14 °F).»

It may be a consequence of a period in which surface air temperature rose faster over land than it did over sea.

Land temperatures themselves are of interest, but as far as I know the only widespread measurements of them have started over the last decade, a period too short to do much trend analysis.

Over the oceans as well as on land, the average global temperature for the 12 - month period that began last December was 14.65 ˚C.

See, the first thing to do is do determine what the temperature trend during the recent thermometer period (1850 — 2011) actually is, and what patterns or trends represent «data» in those trends (what the earth's temperature / climate really was during this period), and what represents random «noise» (day - to - day, year - to - random changes in the «weather» that do NOT represent «climate change»), and what represents experimental error in the plots (UHI increases in the temperatures, thermometer loss and loss of USSR data, «metadata» «M» (minus) records getting skipped that inflate winter temperatures, differences in sea records from different measuring techniques, sea records vice land records, extrapolated land records over hundreds of km, surface temperature errors from lousy stations and lousy maintenance of surface records and stations, false and malicious time - of - observation bias changes in the information.)

For example in the technical summary, it says:» The global combined land and ocean temperature data show an increase of about 0.8 °C over the period 1901 — 2010 and about 0.5 °C over the period 1979 — 2010.

As a result, only 1 out of 7 Global or Land / Ocean (ie, global less polar regions) temperature indices shows a negative trend over that period (HadCRUT4 -0.002 + / - 0.059 C / decade).

But let's look at the long - term NOAA record of tropospheric specific humidity and compare this with the HadCRUT globally and annually averaged land and sea surface temperature anomaly over the same period:

This indicates to me that the rate of energy being added to the oceans has not increased over a longer time period and that there is thus a discrepancy between land and ocean temperature data.

Even rural stations have suffered from land use temperature increases over 150 years and 0.5 degrees of increase would not be recognizable from white noise over that long of a period.

Over this 37 - year period, temperature warmed at an average of 0.50 °F (0.28 °C) per decade over land and 0.20 °F (0.11 °C) per decade over the ocOver this 37 - year period, temperature warmed at an average of 0.50 °F (0.28 °C) per decade over land and 0.20 °F (0.11 °C) per decade over the ocover land and 0.20 °F (0.11 °C) per decade over the ocover the ocean.
