Life on earth requires a constant input of energy from the sun.
Evidence shows atmospheric balance sustained over the past 2.5 billion years has altered due to a rapid rise in earth's average temperature.
The same evidence also blames the burning of fossil fuels, deforestation, melting of permafrost and tundra, and burning fuels for industry and transportation. Science, not hysteria, says Global Warming and its consequences are the Reality.
Sampling deep ice layers enable scientists to measure the atmospheric concentration of various gases, showing that the amount of CO2 present in the atmosphere remained remarkably constant up to the middle of the 19th century at approximately 270 ppm. Beginning in the 1850s with the industrial revolution, we see a constant rise in CO2 in the atmosphere, which continues today. Currently the atmospheric concentration of CO2 stands at a level that has not been achieved for the last 740,000 years.
How do increasing concentrations of CO2 cause a rise in the earth’s atmosphere?
Solar radiation has sufficient energy to enter our atmosphere, but the reflected solar radiation, which has lost significant energy, strikes the greenhouse gas molecules and is reflected back into the atmosphere, unable to escape. Earth's energy budget crashes and our atmospheric temperature rises.
In the past 30 years, Mother Earth suffered a 40% loss of arctic sea ice. The Current Rate of melting could result in a 30' to 50' ocean rise by the end of this century. The Antarctic, alone, holds enough ice to raise sea levels more than 215 feet. Goodbye to: Boston, New York, Charleston, Miami. They will join a New Orleans, nearly gone already!
In 2005, 53 cu. miles of the Greenland ice sheet melted, accounting for 7 % of the annual global sea level rise. Complete melting of the remaining Greenland ice sheet, would be sufficient to raise global sea levels another 23 feet.
Higher temperatures favor the survival rate of insects, which destroy large expanses of forests. Loss of healthy forests lowers the rate of photosynthesis, significantly lowering the natural removal of CO2 from our atmosphere.
27% of the world's coral reefs have been destroyed due to elevated water temperature. Most of the remaining coral reef systems could be dead in 20 years. Lousy snorkeling; worse for sea life!
Warming ocean water is killing vast heat sensitive plankton species, the small animals that are the primary food of many important marine animals. Can the food chain be unbroken?
Most forested areas could become stressed by a lack of water, increasing exposure to pests and fire. Forest fires throw millions of tons of CO2 into the atmosphere, reducing photosynthetic activity. Result: the possible loss of 40% of all forests by 2050. Colorado's current pine beetle issue is one mild sample of the potential damage to come.
Infectious diseases like malaria will spread North as the climate warms. Food production will not be able to feed the projected 9 Billion people on earth in 2050. As our vast corn belt becomes hotter and dryer, poorer northern soils cannot provide the same yields. For each degree of average temperature increase, grain yields decrease by at least 10%. With decreasing food supply and a rapidly growing population, conflicts are inevitable.
Nearly all scientists have concluded: global warming is real and caused by human activity. Science does not argue the inevitability of a future crisis if we maintain our present behaviors.
