Proving carbon dating
He informed the * In 2013, “Forecast the Facts”—a “grassroots human rights organization dedicated to ensuring that Americans hear the truth about climate change”—published the following graphic purporting to show a recent photo of the North Pole: * After publishing an article documenting the facts above, Just Facts contacted Forecast the Facts to offer an opportunity to respond. As of January 2016, Forecast the Facts has not replied or issued a correction.  * The natural variability of Earth’s climate is such that a glacier formerly existed on Hawaii, and glaciers once covered almost all of Canada, New England, and the northern central United States: * In addition to carbon dioxide emissions from the use of fossil fuels, other factors that have been implicated by scientists as primary causes of modern climate change include but are not limited to: * A central debate among scientists about man-made greenhouse gases involves how much natural processes reduce or amplify the effects of these gases.Positive feedbacks amplify the effects, and negative feedbacks diminish them. * The climate models included in the 2007 IPCC report are programmed with positive feedbacks for water vapor that more than double the warming effect of CO2. This is based upon the fact that warmer air evaporates more water, thus creating more water vapor, which is a greenhouse gas.  states that the feedbacks used in climate models are based upon “methods that …
The paper notes that this occurred during a period in which human population increased by 37%, the level of atmospheric CO2 increased by 9%, and the Earth “had two of the warmest decades in the instrumental record.”  attributes this increased productivity to “higher temperatures, longer temperate growing seasons, more rainfall in some previously water-limited areas,” and more sunlight.The following map shows these productivity changes, with green signifying higher vegetation productivity and red lower: Plants need water, light, warmth, nutrition and CO2 to grow.By increasing the CO2 level in the greenhouse atmosphere (typical to 600 ppm instead of normal 400 ppm value), the growth for some plants can be stimulated in an important way, with often yield increases up to 20%, especially for tomato, cucumber, strawberry, etc.It is the “leading international body for the assessment of climate change,” * The first IPCC report (1990) contains the following graph of average global temperature changes over the past 1,000 years based upon proxies.It shows a “Medieval warm period” that was warmer than the present era and a “Little Ice Age” that was cooler.Locking onto local records, no matter how beautiful, can lead to serious errors. found that since 1979, Antarctica has been growing colder in the summer and fall seasons but warmer in the winter and spring seasons, except for 50% of East Antarctica, which has also been cooling in the winter. published a story by Andrew Revkin entitled: “Scientists Report Severe Retreat of Arctic Ice.” The last paragraph of the story reads: “Sea ice around Antarctica has seen unusual winter expansions recently, and this week is near a record high.” * In 2000, James J.
Mc Carthy, a Harvard oceanographer and IPCC co-chair, saw a mile-wide stretch of open ocean at the North Pole while serving as a guest lecturer on an Arctic tourist cruise.
As of July 2015, no similar study has been conducted on a global basis. * From 1979–2014, the three temperate datasets posted above differed from one another by an annual average of 0.13ºF (0.07ºC).
The largest gap between any of the datasets in any year was 0.38ºF (0.21ºC), and the smallest gap was 0ºF/C: * To reconstruct global average temperatures in the era before instrumental measurements were made on a global scale, scientists use proxies that respond to changes in climate, such as the widths of tree rings and certain elements of the geological record, to estimate temperature variations in the past.  * The Intergovernmental Panel on Climate Change (IPCC) is a scientific body established in 1988 by the United Nations and World Meteorological Organization.
A caveat of this finding is that it is based upon weather balloon data, which “must be treated with great caution, particularly at [higher] altitudes….”  states that the “sign and the magnitude of the global mean cloud feedback depends on so many factors that it remains very uncertain.” This is because some types of clouds trap heat while others reflect it.   found that ice clouds (also called cirrus clouds) exert a “strongly negative” feedback to temperature changes, regardless of whether these changes are increases or decreases.
A caveat of this finding is that the feedback process operates “on a time scale of weeks,” and “it is not obvious whether similar behavior would occur on the longer time scales associated with global warming.”  * Other feedbacks that may have “a substantial impact on the magnitude, the pattern, or the timing of climate warming” include snow coverage, temperature gradients in Earth’s atmosphere, aerosols, trace gases, soil moisture changes, and ocean processes. * Per a 2003 report by the United Nations Food and Agriculture Organization, between the mid-1970s and late 1990s, apparent food consumption per person increased by 15% worldwide, 25% in developing countries, and more than 36% in China.
For instance, the sea level in the Indian Ocean is about 330 feet below the worldwide average, while the sea level in Ireland is about 200 feet above average.
