Sentences with phrase «higher amounts of sea level rise»

On the high end, recent work suggests that 4 feet is plausible.23, 3,6,7,8 In the context of risk - based analysis, some decision makers may wish to use a wider range of scenarios, from 8 inches to 6.6 feet by 2100.10,2 In particular, the high end of these scenarios may be useful for decision makers with a low tolerance for risk (see Figure 2.26 on global sea level rise).10, 2 Although scientists can not yet assign likelihood to any particular scenario, in general, higher emissions scenarios that lead to more warming would be expected to lead to higher amounts of sea level rise.

Not exact matches

Co-author Peter Clark, an OSU paleoclimatologist, said that because current carbon dioxide, or CO2, levels are as high as they were 3 million years ago, «we are already committed to a certain amount of sea level rise.»

Since 1990, observed sea level has followed the uppermost uncertainty limit of the Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report (TAR), which was constructed by assuming the highest emission scenario combined with the highest climate sensitivity and adding an ad hoc amount of sea - level rise for «ice sheet uncertainty» (1).

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.

The IPCC estimates that sea levels could be 3 feet higher in 2100, while Hansen and his colleagues predict a rise of at least twice that amount.

Then just in terms of how far a storm will reach, the surge that will happen, we saw with Sandy that it also wasn't controversial to say that when you already have a certain amount of sea level rise, and we do already have that, then when there is a huge storm surge, then because you're starting from an already higher level, this storm is going to reach higher.

Perhaps some gross thermomechanical process of restructuring the climate mechanisms (some small fraction of these were identified in the Stadium Wave paper, for instance) is ongoing, and the energy of restructuring — melting, subliming and carrying away Arctic sea ice and Greenland and Antarctic land ice net to the atmosphere, higher humidity absorbing gross water amounts to a level impacting sea level rise on the millimeter or sub-millimeter level, expansion of land due heat, or more likely erosion, silting and subsidence, and so on — is responsible for a Black Swan.

Again, it's not the gradual long - term rise in sea - levels that is a direct threat - thought to amount to as much as 1 meter, or 3 feet, over the next century - but how that higher base - line affects the natural «sloshing about» of sea.
