Sentences with phrase «observed decadal changes»

With this final correction, the ERBS Nonscanner - observed decadal changes in tropical mean LW, SW, and net radiation between the 1980s and the 1990s now stand at 0.7, -2.1, and 1.4 W m ^ 2, respectively, which are similar to the observed decadal changes in the High - Resolution Infrared Radiometer Sounder (HIRS) Pathfinder OLR and the International Satellite Cloud Climatology Project (ISCCP) version FD record but disagree with the Advanced Very High Resolution Radiometer (AVHRR) Pathfinder ERB record.

Not exact matches

So if there were, say, a decadal - scale 1 % -2 % reduction in cloud cover that allowed more SW radiation to penetrate into the ocean (as has been observed since the 1980s), do you think this would have an impact of greater magnitude on the heat in the oceans than a change of, say, +10 ppm (0.00001) in the atmospheric CO2 concentration?

Additionally, the observed surface temperature changes over the past decade are within the range of model predictions (Figure 6) and decadal periods of flat temperatures during an overall long - term warming trend are predicted by climate models (Easterling & Wehner 2009).

This analytical report covers the first decade of the 21st century and aims at providing a decadal perspective of climate variability and change and its observed impacts on different sectors.

The platform will complement existing GMES / Copernicus pre-operational components, but will focus on datasets which provide information on climate variability on decadal to centennial time scales from observed and projected climate change impacts in Europe, and will provide a toolbox to generate, compare and rank key indicators.

Even a perfect model can deviate significantly from past observed trends or changes, just because the physical system allows variability at decadal time scales; the climate and its trend that we're experiencing is just one of the many climates that we could have had.

I think we should conclude that we agree on the fact that on shorter (decadal) time scales GCM / RCM have shown little regional skill to predict / hindcast observed changes.

This record (Holgate 2007) shows that the average decadal rate of SL change has oscillated from -1 mm / year to +5 mm / year over the 20th C, with the first half of the 20th C showing a slightly higher average rate of +2.0 mm / year than the second half at +1.4 mm / year (IOW no observed acceleration in the rate of SL rise).

Thanks to the availability of data from satellite altimetry, Argo floats, and moored buoys in the tropical Pacific, this decadal phase change is the best - observed decadal climate shift in history.

It gives secular changes on decadal timescales in cloud across the Pacific observed both from the surface and from satellites.

are the CO2 emission also responsible for the decadal change in the atmospheric Ar / N2 ratio observed by Keeling?

The models heavily relied upon by the Intergovernmental Panel on Climate Change (IPCC) had not projected this multidecadal stasis in «global warming»; nor (until trained ex post facto) the fall in TS from 1940 - 1975; nor 50 years» cooling in Antarctica (Doran et al., 2002) and the Arctic (Soon, 2005); nor the absence of ocean warming since 2003 (Lyman et al., 2006; Gouretski & Koltermann, 2007); nor the onset, duration, or intensity of the Madden - Julian intraseasonal oscillation, the Quasi-Biennial Oscillation in the tropical stratosphere, El Nino / La Nina oscillations, the Atlantic Multidecadal Oscillation, or the Pacific Decadal Oscillation that has recently transited from its warming to its cooling phase (oceanic oscillations which, on their own, may account for all of the observed warmings and coolings over the past half - century: Tsoniset al., 2007); nor the magnitude nor duration of multi-century events such as the Mediaeval Warm Period or the Little Ice Age; nor the cessation since 2000 of the previously - observed growth in atmospheric methane concentration (IPCC, 2007); nor the active 2004 hurricane season; nor the inactive subsequent seasons; nor the UK flooding of 2007 (the Met Office had forecast a summer of prolonged droughts only six weeks previously); nor the solar Grand Maximum of the past 70 years, during which the Sun was more active, for longer, than at almost any similar period in the past 11,400 years (Hathaway, 2004; Solankiet al., 2005); nor the consequent surface «global warming» on Mars, Jupiter, Neptune's largest moon, and even distant Pluto; nor the eerily - continuing 2006 solar minimum; nor the consequent, precipitate decline of ~ 0.8 °C in TS from January 2007 to May 2008 that has canceled out almost all of the observed warming of the 20th century.

Understanding the role of the ocean in climate change and making decadal climate forecasts will be greatly enhanced by observations planned as part of an international Global Ocean Observing System.

The study includes an estimate of the effect of the observed stratospheric water decadal decrease by calculating the radiation flux with and without the change, and comparing this to the increase in CO2 forcing over the same period.

The observed changes (lower panel; Trenberth and Fasullo 2010) show the 12 - month running means of global mean surface temperature anomalies relative to 1901 — 2000 from NOAA [red (thin) and decadal (thick)-RSB- in °C (scale lower left), CO2 concentrations (green) in ppmv from NOAA (scale right), and global sea level adjusted for isostatic rebound from AVISO (blue, along with linear trend of 3.2 mm / year) relative to 1993, scale at left in mm).
