Sentences with phrase «globally averaged sea level»

«Recently, various attempts using semi-empirical models have been proposed to estimate globally averaged sea level rise for the 21st century.

It is virtually certain that globally averaged sea level has risen over the 20th century.

As it turns out, estimates of globally averaged sea level rise in the 20th century are irrelevant since Tuvalu's local sea level change is very different from the globally averaged change.

A new paper Assessing the Globally Averaged Sea Level Budget on Seasonal and Interannual Time Scales (Willis 2008) displays up - to - date data on ocean heat.

Not exact matches

Sea levels are rising globally by 3 millimetres on average.

Globally, sea levels rose an average of 1.7 millimetres per year between 1901 and 2010.

«Globally averaged sea - level rise anomaly (relative to 1986 — 2005) owing to thermal expansion (red line, as in Fig. 2), and the example from the IPCC AR4 (dashed green line) for RCP8.5 (a), RCP4.5 (b) and RCP2.6 (c).

Since 1850, CO2 levels rose, as did the «globally and annually averaged land and sea surface temperature anomaly» (for what it's worth), but nobody knows whether or not the increase in CO2 had anything whatsoever to do with the warming.

Northern sea ice is nearly back to average levels globally for the first time in at least a decade after years of spectacular declines.

The GRACE observations over Antarctica suggest a near - zero change due to combined ice and solid earth mass redistribution; the magnitude of our GIA correction is substantially smaller than previous models have suggested and hence we produce a systematically lower estimate of ice mass change from GRACE data: we estimate that Antarctica has lost 69 ± 18 Gigatonnes per year (Gt / yr) into the oceans over 2002 - 2010 — equivalent to +0.19 mm / yr globally - averaged sea level change, or about 6 % of the sea - level change during that period.

Projected globally averaged sea - level rise at the end of the 21st century (2090 to 2099), relative to 1980 to 1999 for the six SRES scenarios, ranges from 0.19 to 0.58 m (Meehl et al., 2007).

The Thwaites Glacier alone is contributing about 10 % to the current globally averaged rate of sea level rise, which is about 0.13 inches per year, Joughin says.

Some locations, such as Brest, have measured a very slight acceleration in sea - level rise in the late 1800s or early 1900s, but globally averaged coastal sea - level rise has not accelerated since the 1920s.

However you slice it, lolwot, there is a current «pause» (or «standstill») in the warming of the «globally and annually averaged land and sea surface temperature anomaly» (used by IPCC to measure «global warming»), despite unabated human GHG emissions and CO2 levels (Mauna Loa) reaching record levels.

Over 1993 — 2014, the resulting globally averaged geocentric sea level change is 8 % smaller than the barystatic contribution.

«Over 1993 - 2014, the resulting globally averaged geocentric sea level change is 8 % smaller than the barystatic contribution,» the researchers wrote in their study.

Taken together, the average of the warmest times during the middle Pliocene presents a view of the equilibrium state of a globally warmer world, in which atmospheric CO2 concentrations (estimated to be between 360 to 400 ppm) were likely higher than pre-industrial values (Raymo and Rau, 1992; Raymo et al., 1996), and in which geologic evidence and isotopes agree that sea level was at least 15 to 25 m above modern levels (Dowsett and Cronin, 1990; Shackleton et al., 1995), with correspondingly reduced ice sheets and lower continental aridity (Guo et al., 2004).
