«When we modeled future shoreline change with the increased rates of sea level rise (SLR) projected under the IPCC's «business as usual» scenario, we found that increased SLR causes an average 16 - 20 feet of additional shoreline retreat by 2050, and an average of nearly 60 feet of additional retreat by 2100,» said Tiffany Anderson, lead author and post-doctoral researcher at the UH Mānoa School of Ocean and Earth Science and Technology.

In their latest paper, published in the February issue of Nature Geoscience, Dr Philip Goodwin from the University of Southampton and Professor Ric Williams from the University of Liverpool have projected that if immediate action isn't taken, Earth's global average temperature is likely to rise to 1.5 °C above the period before the industrial revolution within the next 17 - 18 years, and to 2.0 °C in 35 - 41 years respectively if the carbon emission rate remains at its present - day value.

The misunderstanding stems from data showing that during the past decade there was a slowing in the rate at which the earth's average surface temperature had been increasing.

Scientists generally agree the Earth has been cooling over the past several thousand years at an average global rate of -0.20 degrees C / millennium.

As a result of our in - depth adoption process, Heaven on Earth's return rate is far below the national average and at the same time, our adoption totals have been steadily increasing, projected to exceed 500 in 2017.

As a result, the Earth has warmed at an alarming rate over the past century, with average temperatures increasing by more than 0.8 °C (1.5 °F).

Using satellite radiation balance measurements and ocean heaing measurements the earth appears to be gaining heat at a rate of 0.6 Watts / M2 on average.

At the current rate of progression, the increase in Earth's long - term average temperature will reach 1.5 °C (2.7 °F) above the 1850 - 1900 average by 2040 and 2 °C (3.6 °F) will be reached around 2065.

These facts were enough for an NAS panel, including Christy, to publish a report Reconciling Observations of Global Temperature Change which concluded that «Despite differences in temperature data, strong evidence exists to show that the warming of the Earth's surface is undoubtedly real, and surface temperatures in the past two decades have risen at a rate substantially greater than average for the past 100 years»

Many of the mechanisms are like that — the tides, the direct inductive heating, the heating caused by the days influx of falling meteorites — which incidentally is far greater than the rate of heat loss through outgassing, as meteoric dust and matter infalls at an average rate of at least millimeters per decade, from my own direct measurements — they have «impressively» large amounts of annual energy associated with them, right up to where you divide by the surface area of the earth and the number of seconds in a year.

Wikipaedia says «the rate of species extinctions [not just animal species] at present is estimated at 100 to 1000 times «background» or average extinction rates in the evolutionary time scale of planet Earth» and cites J.H.Lawton and R.M.May, Extinction rates, OUP.

Argo data reveal that in 2005 — 2010 the ocean's upper 2000 m gained heat at a rate equal to 0.41 W / m2 averaged over Earth's surface [70].

«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.

The primary problem is that the entire global warming movement is being sold based on telling people that the global average temperature of the Earth is increasing at a dangerous rate.

For the 120th time (okay, maybe it's only the 19th), the temperature at the earth's surface is determined by the lapse rate and the level in the atmosphere at which the temperature is constrained, which is the effective radiating level, i.e., the average level from which radiation can successfully escape to space.

While all the numbers in the cartoon may well be close to reality, it is interpreted (probably even by the authors) as demonstrating that a magic «greenhouse effect» keeps Mother Earth at an average temperature of 15 C, which would irradiate at a rate of 390 Wm - 2.

The solar constant for Earth is commonly given at 1366 W / m ^ 2, and to make a simple average of what is absorbed over the surface and atmosphere, and absorption rates etc, (and the outgoing emissions, spread over the entire sphere), when the wattage is proportional to the fourth power of T, introduces a few complications.

According to the Department of Energy, in 2001 the world consumed at an average rate of more than 13 trillion watts (13 terawatts, TW), just a fraction of the 120,000 TW of energy available that falls to Earth - free.

These feedbacks are the primary source of uncertainty in how much the earth will warm (side note: the question that most climate scientists who study the forcing due to CO2 try to answer is, how much will the long - term globally averaged surface temperature of the earth rise due to an rapid rise of CO2 to twice its industrial level, that is, 270 ppm to 540 ppm; it is currently about 380 last time I checked, and rising at ~ 3ppm / year, although this rate of change appears to be accelerating).
