This snowpack accumulation near the poles, which gets its water via the Arctic and Antarctic oceans, that in turn rob it from equatorial latitudes
of our oceans, also results in a reduction in the earth's spin axis moment
of inertia and causes the spin
rate to increase as evidenced in the recent history
of the
rate at which Leap Seconds are added to our calendar (see Wysmuller's Toucan Equation for more on this evidence that during this
warm time
with much greater polar humidity, earlier seasonal, later seasonal and heavier snows are beginning to move water vapor from the oceans to the poles to re-build the polar ice caps and lead us into a
global cooling, while man - made CO2 continues to increase http://www.colderside.com/faq.htm).

«Climate science» as it is used by warmists implies adherence to a set
of beliefs: (1) Increasing greenhouse gas concentrations will
warm the Earth's surface and atmosphere; (2) Human production
of CO2 is producing significant increases in CO2 concentration; (3) The
rate of rise
of temperature in the 20th and 21st centuries is unprecedented compared to the
rates of change
of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate
of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5)
global climate models, while still not perfect, are good enough to indicate that continued use
of fossil fuels at projected
rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The
global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity
of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's
rate) and continue further reductions after 2050; (9) Even
with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.
Australia's Bureau

with some decades
warming more rapidly than others.
Note we're using BEST land area, so actual

«Sure, they'll probably try to confuse us
with trick questions: Like why, apart from natural 1998 and 2015 El Nino spikes, satellites haven't recorded any statistically significant
global warming for nearly two decades; why sea levels have been rising at a constant
rate of 7 inches per century without acceleration; and why no category 3 - 5 hurricanes have struck the U.S. coast since October 2005 — a record lull since 1900.
«
With global temperatures
warmer now than they were at the beginning
of the last century, that means our temperatures are
warmer too, which increases the
rate of evaporation and increases the demands on water, increases the stress on the water supply, and also leaves us more susceptible to breaking the high - temperature record, which we've been doing lately,» Nielsen - Gammon said.

The draft paper holds out little hope that countries will be able to limit
global warming to the agreed goal
of 2 degrees Celsius,
with temperatures likely to rise by almost 4 degrees by the end

If that theory is true, and if a major El Niño is indeed in the works, the previously rapid

But they have not been doing so at a
rate consistent
with keeping cumulative carbon emissions low enough to reliably stay below the international target
of less than 2 degrees Centigrade
of global warming.
Therefore in comparing
rates of global warming today
with past
rates of global warming, it is essential to use
global averages, rather than comparing a
global average
with a regional proxy.
