An analysis of the contributions of humans to global warming

A number of previous and subsequent studies had suggested that both the Medieval Warm Period and the Little Ice Age 35 had produced climate changes much greater than the 0. This, however, is demonstrably false.

All of these studies, using a wide range of independent methods, provide multiple lines of evidence that humans are the dominant cause of global warming over the past century, and especially over the past 50 to 65 years Figure 1.

Improving the models' representation of clouds is therefore an important topic in current research. Although attribution science is clearer for some types of events than for others, it is an important step to provide predictive forecasts of extreme events at longer lead times, reducing risks and improving preparedness.

Increasing greenhouse gas concentrations Since the industrial revolution, the atmospheric concentrations of carbon dioxide and some other important greenhouse gases have been increasing as a consequence of the burning of fossil fuels, and the development of various industrial processes and chemicals.

How Do We Know that Humans Are the Major Cause of Global Warming?

It may be similar to arguing with someone about the New World Order NWO as you need to find out exactly where they stand before engaging with them. Tsunamis could be generated by submarine landslides caused by warmer ocean water thawing ocean-floor permafrost or releasing gas hydrates.

Denialists jumped on the bandwagon in regards to this shift making many grandiose claims that it invalidates all of the data that proves this has been the hottest decade in recorded history. Glacier retreat calculations[ edit ] Scientists have found DNA from ancient animals in an ice layer of Greenland1.

Some of these influences can have a cooling effect on the earth's surface and lower atmosphere. How do we date the ice cores. Though some have taken non-committal stances, the vast majority of scientific bodies are convinced by the evidence. Obviously, temperatures will increase only if the net influx of energy exceeds the radiation of the energy back to space.

Scientists Agree: Global Warming is Happening and Humans are the Primary Cause

Most importantly, this is one of the finest examples of cherry picking since deniers only look at the data sets that match the conclusions they want to see. Are these suggestions the best way to address the global warming issue. These data strongly suggest that the rapid increase of CO2 in the last century is not the result of a natural process.

Global warming

Cold water is "heavier" than warm water and salty water is "heavier" than fresh water. Although more greenhouse gases are emitted in the Northern than in the Southern Hemisphere, this does not contribute to the difference in warming because the major greenhouse gases persist long enough to diffuse within and between the two hemispheres.

One good example of plants that consume plenty of CO2 are pine trees used in farming. Some climatologists have criticized the attention that the popular press gives to "warmest year" statistics.

Multiple independently produced datasets confirm that from to the global average land and ocean surface temperature increased by 0.

Climate Science Glossary

A study by Naomi Oreskes reviewed over peer-reviewed papers and found none that dissented from the consensus. On that Record Warmest Claim January 22nd, by Roy W. Spencer, Ph. D. Over the years, the models of attribution science have become more sophisticated, and, in addition to attributing global warming to human caused emissions, they are also able to determine the contributions of global warming to extreme events (like floods, heat waves, storms, etc).

Understanding The Human Contribution To Global Warming. Posted on March 8, by tonyheller. Antarctic ice cores show regular swings in temperature of more than 20 degrees. These were all natural, but the recent zero degree swing was caused by your SUV. Global warming, also known as anthropogenic (or human-caused) global warming, is the rising average temperature of Earth's atmosphere and oceans and its related effects.

Global warming denialism refers to fossil fuel industry-funded claims that global warming. A) Is not happening B) Is not caused by humans C) Is not significant. Comprehensive and meticulously documented facts about global warming.
