This is followed by several years of variability around the 4 million square kilometers level, until another dramatic reduction event takes place.

Not exact matches

However, in order to come close to achieving a reduced target hypoxic zone of 5,000 square kilometers (1930.5 square miles) by 2050, nitrogen levels would have to be brought to zero — a scenario that the researchers note in their paper is «not only considered unrealistic, but also inherently unsustainable.»

If sea level rises more slowly and land sinks less, the structures would build up 1000 square kilometers off the present coast.

With conservative assumptions about sea level rise and the subsidence of the area, two diversion structures — large concrete sluices placed in the river embankment — would create about 700 square kilometers of land over 30 years, said Gary Parker of the University of Illinois, Urbana Champaign.

Paulo Moutinho, a senior climate researcher at the Amazon Environmental Research Institute in Brasilia, says 2030 is «too late» to stop deforestation, and that the current level of 5000 square kilometers being cleared per year is still too high to preserve ecosystem services.

The only problem with all the predictions about the level of the World Ocean rising is that, the World Ocean is refusing to rise up in support of the predictions, the other problem is that ice is frozen fresh water and frozen fresh water only covers about 5 % of this planet above sea level and frozen water under the level of the World Ocean does not count as the World Ocean will fall a small amount if that ice melts, so if the ice there is enough to get the World Ocean to rise and significant amount then it must be piled up very high, I cubic kilometer of water as ice, should it melt, would make 1000 square kilometers rise by one meter, so when you use this simple math then somewhere on the planet, above the level of the sea, then there must be over 500,000 cubic kilometers of ice, piled up and just waiting to melt, strange that no one can find that amount of ice, all these morons who talk about the rise of the World Ocean in tens of meters, this includes you Peter Garrett or Mr. 7 Meters, the ice does not exist to allow this amount of rise in the World Ocean, it is just not there.

Does this suggest a new level of reduced summer ice extent persisting at around 5.0 million square kilometers, relative to a value of 6.0 million square kilometers in the early 2000s?

In September 2007 sea ice extent reached its lowest level since the satellite record began in 1979; the monthly extent, 4.28 × 106 square kilometers, surpassed the previous sea ice minimum record (set in 2005) by 1.28 × 106 square kilometers [Stroeve et al., 2008].

«A sea level rise of up to 0.5 meters by 2100 may already be unavoidable even in a scenario of deep emissions cuts — we estimate that this could inundate 2000 square kilometers in Bangladesh, which is 1.6 percent of the country and would affect 2.5 million people.

«Dr. Amstrup, however, said that according to the National Snow and Ice Data Center, the average September sea ice extent for the years 2007 to 2017 was 4.5 million square kilometers, «nowhere near the low levels projected it would be by the middle of the century.»

When dividing the mass balance value by the surface area of the oceans (361.6 million square kilometers), the final result is 0.58 millimeters of sea level rise per year.

Global mass balance data are transformed to sea - level equivalent by first multiplying the ice thickness (meters) lost to melting by the density of ice (about 900 kilograms per cubic meter), to obtain a water equivalent thickness, and then multiplying by the surface area of these «small» glaciers (about 760,000 square kilometers).

If we attempted to bring the Arctic back to long - term average levels of «ice,» we would need to add approximately 2.6 million square kilometers (1 million square miles) of foam to the Arctic Ocean.

In contrast to the polar regions, the network of lower latitude small glaciers and ice caps, although making up only about four percent of the total land ice area or about 760,000 square kilometers, may have provided as much as 60 percent of the total glacier contribution to sea level change since 1990s (Meier et al. 2007).

This is an increase of 1 million square kilometers from the July Outlook, reflecting the persistence of low sea level pressure (SLP) over the central Arctic that resulted in ice divergence and a more fractured ice cover.

To find out how much of an effect this has on sea level, a team of Dutch scientists led by hydrologist Yoshihide Wada, a Ph.D. researcher at Utrecht University, divided the Earth's land surface into 31 - by -31-mile (50 - by - 50 kilometer) squares on a grid to calculate present and future groundwater usage.

The melting characteristics of such a huge ice sheet — spanning 656,000 square miles (1.7 million square kilometers)-- is important for various reasons, particularly its potential effect on sea levels.
