Not exact matches

Temperature changes relative to the corresponding average for 1901 - 1950 (°C) from decade to decade from 1906 to 2005 over the Earth's continents, as well as the entire globe, global land area and the global ocean (lower graphs).

* Surface temperature changes relative to 20th Century global average (1901 - 2000) Source data NOAA - NCEI State of the Climate: Global Analysis [Web + data download]

Our result would peg the average land temperature change during the 1810s as about -0.7 C (+ / - 0.4 C at 95 %) relative to the 19th century average, which is broadly consistent with prior estimates.

The efficacy of a forcing is the climate sensitivity (in terms of global average surface temperature change per unit global average RF) of that forcing relative to a standard type of forcing.

[Response I'm not sure what point you are trying to make here, but if you feel that you can only assess whether temperatures are changing by looking at 30 - year averages, consider the following: Global mean temperature anomalies (in degrees C, relative to 1961 - 90 reference period): 1885 - 1914: -0.35; 1915 - 1944: -0.18; 1945 - 1974: -0.07; 1975 - 2004: +0.21.

Relatively (it's always relative changes that are most relevant to breaking the climate averages) cool waters from the Caribbean have over recent weeks and months increasingly spread to the northeast, across the Atlantic Gulf Stream, creating a negative temperature anomaly around the islands of the Azores and reaching further to the British Isles and the North Sea, where sea water is low due to the very cold December.

The program calculates trends in temperature anomalies — not absolute temperatures — but changes relative to the average temperature for the same month during the period of 1951 - 1980.

Model projections for precipitation changes are less certain than those for temperature.12, 2 Under a higher emissions scenario (A2), global climate models (GCMs) project average winter and spring precipitation by late this century (2071 - 2099) to increase 10 % to 20 % relative to 1971 - 2000, while changes in summer and fall are not expected to be larger than natural variations.

Maps show projected change in average surface air temperature in the later part of this century (2071 - 2099) relative to the later part of the last century (1970 - 1999) under a scenario that assumes substantial reductions in heat trapping gases (B1) and a higher emissions scenario that assumes continued increases in global emissions (A2).

GISS measures the change in global surface temperatures relative to average temperatures from 1951 to 1980.

The old story line: People need to worry about climate change because doubling the atmosphere's concentration of carbon dioxide relative to its preindustrial level would probably raise global average temperatures by 2.7 to 8 degrees Fahrenheit.

The percentage «remaining» in the atmosphere seems to correlate well with the annual change in global average temperature compared to the previous year, with years of relative warming showing higher % - age of the emitted CO2 «remaining» in the atmosphere.

Rather than dealing with trends, instead we ask how much has the TLT satellite brightness temperature vertically relative weighted average changed in absolute levels, compared to what we'd find year to year or within groups of years.

If there is deep - water formation in the final steady state as in the present day, the ocean will eventually warm up fairly uniformly by the amount of the global average surface temperature change (Stouffer and Manabe, 2003), which would result in about 0.5 m of thermal expansion per degree celsius of warming, calculated from observed climatology; the EMICs in Figure 10.34 indicate 0.2 to 0.6 m °C — 1 for their final steady state (year 3000) relative to 2000.

22 Land areas are projected to warm more than the oceans with the greatest warming at high latitudes Annual mean temperature change, 2071 to 2100 relative to 1990: Global Average in 2085 = 3.1 o C

The analyses are based on calculating temperature differences at one point in time relative to the average over a certain period (anomalies) and creating a time series of averaged global temperature change.

The temperature changes are relative to the global average surface temperature of 1961 - 1990.

The map below presents the estimated change in average surface air temperature for 2014 relative to the thirty - year average from 1981 to 2010.

Projections for global average temperatures relative to 1850 - 79 (upper chart), rates of glacier change (middle) and total glacier mass (lower chart) for the 21st century.

«Based on all above findings and our compilation (Figure 4.4, Table 4.1 ″) we estimate that on average 20 % to 30 % of species assessed are likely to be at increasingly high risk of extinction from climate change impacts possibly within this century as global mean temperatures exceed 2 °C to 3 °C relative to pre-industrial levels (this chapter).

This paper assesses the three pathways in the light of Working Group I's recently released contribution to the Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC 2013), which provided three specific global carbon dioxide (CO2) budgets, and associated them with specific risks of a global surface temperature increase of more than 2 °C by the end of this century, relative to the 1850 — 1900 average.

Probability density functions from different studies for global mean temperature change for the SRES scenarios B1, A1B and A2 and for the decades 2020 to 2029 and 2090 to 2099 relative to the 1980 to 1999 average (Wigley and Raper, 2001; Knutti et al., 2002; Furrer et al., 2007; Harris et al., 2006; Stott et al., 2006b).
