Sentences with phrase «between global average sea level»

Not exact matches

Third, using a «semi-empirical» statistical model calibrated to the relationship between temperature and global sea - level change over the last 2000 years, we find that, in alternative histories in which the 20th century did not exceed the average temperature over 500-1800 CE, global sea - level rise in the 20th century would (with > 95 % probability) have been less than 51 % of its observed value.

For a future of continued growth in emissions the new results indicate a likely global average sea - level rise between 1.1 and 2.1 meters (3.6 to 6.9 feet)-- roughly double the IPCC - consistent estimate.

Regardless of emissions pathway and approach, there is likely to be between about 16 and 40 cm (0.5 and 1.3 feet) of global average sea - level rise in the first half of the century.

On average, the world's glaciers and ice caps lost enough water between 1961 and 1990 to raise global sea levels by 0.35 - 0.4 mm each year.

Global average sea level was likely between 4 and 6 m higher during the last interglacial period, about 125,000 years ago, than during the 20th century, mainly due to the retreat of polar ice -LRB-

Global average sea level was likely between 4 and 6 m higher during the last interglacial period, about 125,000 years ago, than during the 20th century, mainly due to the retreat of polar ice (Figure TS.21).

If we do nothing to reduce our carbon emissions, scientists project that global sea level could rise as much as nearly two feet (59 centimeters) over recent average levels by the end of this century.14, 15 If, on the other hand, we make significant efforts to reduce heat - trapping emissions, sea - level rise between now and the end of the century could be limited to at most 1.25 feet (38 centimeters).14, 15

Global average temperatures were between 5.4 and 7.2 degrees Fahrenheit (3 to 4 degrees Celsius) higher than today, and sea level was as much as 131 feet (40 meters) higher in some places.

It is very likely that the mean rate of global averaged sea level rise was 1.7 [1.5 to 1.9] mm yr — 1 between 1901 and 2010, 2.0 [1.7 to 2.3] mm yr — 1 between 1971 and 2010 and 3.2 [2.8 to 3.6] mm yr — 1 between 1993 and 2010.

I've looked at the global average salinity data at NODC and there is a clear correlation between inter-annual salinity variability and inter-annual sea level change, such that salinity increases at the same time as SL decreases.

The most recent report from the U.N. Intergovernmental Panel on Climate Change projected a global average sea level rise of between about one to three feet, although that report did not take the new findings on Antarctic ice melt into account.

By 2100, global average sea level rise could be as low as 25 cms, or as high as 123 cms; between 0.2 % and 4.6 % of the world's population could be affected by flooding each year; and losses could be as low as 0.3 % or as high as 9.3 % of global gross domestic product.

[4] Between 1870 and 2004, global average sea levels rose 195 mm (7.7 in), 1.46 mm (0.057 in) per year.

Statistically significant trends obtained from records longer than 40 years yielded sea - level - rise estimates between 1.06 — 1.75 mm / yrear - 1, with a regional average of 1.29 mm yr - 1, when corrected for global isostatic adjustment (GIA) using model data, with a regional average of 1.29 mm - 1..

The net loss of billions of tons of ice a year added about 11 millimeters — seven - sixteenths of an inch — to global average sea levels between 1992 and 2011, about 20 % of the increase during that time, those researchers reported.

Regardless of emissions pathway and approach, there is likely to be between about 16 and 40 cm (0.5 and 1.3 feet) of global average sea - level rise in the first half of the century.

For a future of continued growth in emissions the new results indicate a likely global average sea - level rise between 1.1 and 2.1 meters (3.6 to 6.9 feet)-- roughly double the IPCC - consistent estimate.

The exact speed with which these are going to contribute to sea level rise is highly uncertain, the synthesis report says, but the best scientific estimate — based on observed correlation between global average temperatures and sea level rise over the past 120 years — shows that by 2100 we will experience sea level rise of one meter or more.
