The concept behind the greenhouse effect and its contribution to global warming

One reader pointed out that the Arctic region has dew points above freezing during a significant portion of the year. Many people do not understand this important concept. As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world—in the atmosphere, on land, and in the oceans.

Some of these hypothetical effects would cause warming and some would cause cooling. T6 is equivalent to just 0. Pickens think that we would now be able to produce another , cubic feet each year for his project.

The percentage of emitted carbon dioxide that ends up in the atmosphere can be treated as approximately constant.

Climate Science Glossary

The documentary End of the Line says: We will often abbreviate "parts per million" of the total atmosphere as ppm. Weather extreme would increase: It is important to realize that the original factor of 0. Every gallon of home heating oil you use, the same. To communicate the sheer amount of heat our planet is accumulating, we have created this widget, embeddable on blogs and also available as a Facebook app, an iPad app, and an iPhone app.

As humans discovered the Industrial Revolution, where initially coal was burned to power many factories, when THAT fossil fuel was burned oxidizedthe carbon which had been trapped in the coal then combined with oxygen from the air to create about three pounds of carbon dioxide from each pound of coal that was burned.

In the process, everything else - all the little stuff that lives on the bottom, the sponges and the coral and all the habitat for baby animals - you wipe all that out.

As a result of global warming there has been increased rainfall in the Northern Hemisphere, draught in Asua and Africa. Electricity generation is the largest source of greenhouse gas emissions in the United States, followed by transportation.

While the results necessarily remain uncertain, they undoubtedly represent our most complete picture yet of the global state of fish catches. Between the beginning of the Industrial Revolution around andwe humans managed to add about billion tons of carbon dioxide to the atmosphere.

One recent paper on this question is Monckton of Brenchley et al. Educate people on harmful effects of global warming. If you have many children, it's difficult to support them. It also drives this ocean revitalizing train of currents through every major corner of the world ocean.

And, if our usage was a lot less than it is, they would be brilliant approaches.

Anthropogenic Climate Change

Therefore, although the actual warming cannot be greater than the predicted estimate, it could be considerably less. Such "experts" quote huge numbers to refer to amounts of the recycled parts of the Carbon Cycle, and ignorantly claim that the naturally occurring giant numbers are more dangerous than relatively smaller numbers which describe the emissions due to burning fossil fuels.

A more exhaustive study, taking over a decade shows that the annual catches between and were much bigger than thought, but that the decline after the peak year of was much faster than official figures. However, mega-eruptions or a series of eruptions can have a cooling effect that take decades to wear off, giving a perceived warming effect as temperatures return to normal.

Dr Stephen Farish, Professor of Epidemiological Statistics at the University of Melbourne, kindly verified the reliability of the algorithm that determines the trend on the graph and the correlation coefficient, which is very low because, though the data are highly variable, the trend is flat.

If this is a recurring phenomena, it's going to change the productivity of the northwest Atlantic in ways that we don't know yet. The black curve is a linear extrapolation calculated from the DOE estimates of total current greenhouse gases. However, what we have gives us 11 full years of data.

Climate Change Indicators: Greenhouse Gases

The known anthropogenic warming component has offset and overpowered natural cooling factors, so that a slight warming trend is still detectable. But as ecologist Douglas McCauley explains in a Yale Environment interview, marine life now face numerous threats even more serious than overfishing.

Chemical reactions caused by that excess CO2 have made seawater grow more acidic, depleting it of the carbonate ions that corals, mollusks and calcifying plankton need to build their shells and skeletons.

Doesn't this increase the predicted temperature beyond the 1. This shows that doubling CO2 over its current values should increase the earth's temperature by about 1.

Given the same amount of absorbed solar energy coming in, the amount of IR escaping to space at the top of the atmosphere will indeed be the same no matter how many greenhouse gases there are (assuming the system is in equilibrium). EVERY (6 pound) gallon of gasoline or diesel burned adds pounds of CO 2 to the Earth's atmosphere note 1, essentially have been doing such things for years.

People are confused by the fact that only very minimal average temperature rises have been detected, and so they claim that no Global Warming is occurring. Black carbon is second only to carbon dioxide for its contribution to global warming the greenhouse effect produces warming of the lower atmosphere (the troposphere), The physical effect of global warming on oceans include an increase in acidity.

* Global warming is defined by the American Heritage Dictionary of Science as “an increase in the average temperature of the Earth’s atmosphere,” either by “human industry and agriculture” or by natural causes like the Earth has “experienced numerous” times “through its history.”.

NOTE: GWP (Global Warming Potential) is used to contrast different greenhouse gases relative to CO2.

Global Warming - The Physics of the Process

Compared to the concentration statistics in Table 1, the GWP. Anthropogenic climate change refers to the production of greenhouse gases emitted by human activity. By examining the polar ice cores, scientists are convinced that human activity has increased the proportion of greenhouse gases in the atmosphere, which .
