global atmospheric circulation, making weather observations, forecasting, synoptic charts, hurricanes, regional climate, palaeoclimates and anthropogenic climate change.
The people of Earth need fresh
water and we all need to be more concerned about having more of it, even it takes more energy to make it or having to listen to the fearmongering of Leftist opinion - makers like Obama and Kerry who claim respectively that, «no challenge — poses a greater threat to future generations than climate change,» and, that
global warming is, «perhaps the world's most fearsome weapon of
mass destruction.»
Given that people on Brulle's side of the
Global Warming / Climate Change argument have been making false claims for decades — for example, that New York and Washington would be under
water by the year 20004 — and given that the
mass media sound daily alarms about the climate threat, the statement in the National Research Council report that «some» information sources are «affected» by campaigns opposed to policies that would limit carbon dioxide emissions is scant foundation for believing a massive conspiracy exists.5
This may be me advertising my ignorance but if the OHC is of interest as against the SST why do we use a parameter of «
global temperature» which is an amalgam of SST and air temperature over land rather than a total heat content or a temperature normalised say for
mass or thermal density (normalise to the properties of
water say)?
The myriad of processes that transform energy, that result in the motion of
mass in the atmosphere, in oceans, and on land, processes that drive the
global water, carbon, and other biogeochemical cycles, all have in common that they are irreversible in their nature.»
Per Hsu and Velicogna 2017, between April 2002 and October 2014
global mean sea level grew by about 1.8 millimeters per year, with 43 percent of the increased
water mass coming from Greenland, 16 percent from Antarctica, and 30 percent from mountain glaciers.
The top right hand quadrant of the World Economic Forum's annual
Global Risks Report is home to highly likely, high impact dangers that have not been resolved: climate change, weapons of
mass destruction,
water scarcity,
mass forced migration, and energy price shocks.
We use realistic estimates of
mass redistribution from ice
mass loss and land
water storage to quantify the resulting ocean bottom deformation and its effect on
global and regional ocean volume change estimates.

«Our climate simulations, using a simplified three - dimensional climate model to solve the fundamental equations for conservation of
water, atmospheric
mass, energy, momentum and the ideal gas law, but stripped to basic radiative, convective and dynamical processes, finds upturns in climate sensitivity at the same forcings as found with a more complex

Rise of the

Depending on how the continents are arranged the
global ocean conveyor belt changes and having a land

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).
The IPCC has already concluded that it is «virtually certain that human influence has warmed the
