About 20,000 years ago, at peak glaciation, sea level was about 400 feet / 120 meters lower than today.
By 7,000 years ago all the low-altitude, mid-latitude glaciers had melted.
Many scientists believe sea level was higher than today during the Holocene Thermal optimum from 9,000 to 5,000 years ago when the Sahara was green.
Hundred of islands near the Equator in Papua, Indonesia, have been undercut by the sea.
That suggests little change in sea level in thousands of years, because it takes a long time for so much rock erosion to occur from gentle wave action in a tropical sea.
Temperature has risen at a steady slow rate in Central England since 1700, in spite of the fact that CO2 emissions were tiny before 1850.
CO2 emissions began an exponential rise after 1950.
After freezing regularly during the Little Ice Age, the River Thames froze for the last time in 1814, as the Earth moved into the Modern Warm Period.
There was a 30-year period of warming from 1910-1940.
Then a cooling from 1940 to 1975, as CO2 emissions rose exponentially.
The 25-year warming from 1975-2000 was very similar in duration and temperature rise to the rise from 1910-1940, which was not blamed on CO2.
How many politicians are aware of this statement about climate change from the IPCC in 2007?
“we should recognize that we are dealing with a coupled nonlinear chaotic system (climate), and therefore that the long-term prediction of future climate states is not possible.”
Climate models have grossly exaggerated the actual global warming for 30 years.
The only trends the computer models predict accurately are ones that have already occurred.
All life is carbon-based.
The carbon cycle should be taught to our children rather than demonizing CO2.
CO2 is essential for life.
CO2 must be at a certain level in the atmosphere for the survival of plants, the primary food for humans and animals.
Trees and food crops are capable of growing much faster at higher levels of CO2 than present in the atmosphere today.
The optimum level of CO2 for plant growth is at least 1,000 ppm, more than double today's level of 400 ppm ... and possibly up to 2,000 ppm.
We should celebrate more CO2 in the air.
Only half of the CO2 we emit from burning fossil fuels is showing up in the air.
The rest is going somewhere else -- most likely into an increase in global plant biomass.
There are 850 billion tons of carbon as CO2 in the atmosphere.
When modern life-forms evolved over 500 million years ago there was nearly 15,000 billion tons of carbon in the atmosphere, 17 times today’s level.
Fossil fuels are made from plants that pulled CO2 from the atmosphere.
100,000,000 billion tons of carbon have been turned into stone by marine species that learned to make armor-plating (shells) for themselves by combining calcium and carbon into calcium carbonate.
Limestone, chalk, and marble hold 99.9% of all the carbon ever present in the global atmosphere.
The vast majority of the CO2 originally from the atmosphere has been sequestered and stored in carbonaceous rocks where it cannot be used as food by plants.
The past 150 million years has seen a steady draw down of CO2 from the atmosphere.
The amount of CO2 in the atmosphere was reduced about 90% during this period.
If this trend continued the low CO2 level would have threatened the survival of plants, which require a minimum of roughly 150 ppm to survive.
During the last glaciation, which peaked 18,000 years ago, CO2 bottomed out at 180 to 200 ppm -- the lowest CO2 level in the history of the Earth -- already low enough to stunt green plant growth.
When the glaciers began melting, CO2 rebounded to 280 ppm.
With human emissions causing CO2 to reach 400 ppm now, plants are still restricted in their growth rate.
We can be sure higher levels of CO2 will result in increased plant growth and biomass.
"Human emissions of carbon dioxide have saved life on Earth from inevitable starvation and extinction due to lack of CO2”. Patrick Moore PhD
Society has been misled into believing global CO2 and temperature are too high, when the opposite is true for both.
