A comprehensive analysis of the greenhouse effect

The second class of policy action, one that tends to be favored by many economists, is adaptation For example, ecologists are concerned that the destruction rate of tropical forests attributed to human expansion is eroding the genetic diversity of the planet Kutzbach and F.

The optimal climate for crops may change, requiring significant regional adaptations. The faster the changes take place, the less societies or natural ecosystems will be able to adapt to them without potentially serious disruptions.

The relation between the observed century-long trend and the predicted warming could still be chance occurrences, or other factors, such as solar constant variations or volcanic dust, may not have been accounted for correctly during the past century--except during the past decade when accurate measurements began to be made.

It has a much weaker magnetic field meaning less protection from solar radiation and heating effects [41] Its very dense atmosphere consists mainly of carbon dioxide. What is controversial about the greenhouse effect is exactly how much Earth's surface temperature will rise given a certain increase in a trace greenhouse gas such as CO2.

How can models be verified?

implications of greenhouse effect

It is important to ask how long it might take the scientific community to be able to provide more credible time-evolving regional climatic anomaly forecasts from increasing greenhouse gases; S.

A comprehensive analysis of the greenhouse effect

Making progress in reducing the large uncertainties in projections of future climate will require addressing a number of fundamental scientific questions relating to the buildup of greenhouses gases in the atmosphere and the behavior of the climate system. Edmonds and J. Mitigate the impact of climate change by aggressively enacting policies that actually reduce the concentration of CO2 in the atmosphere. Indeed, many people interpreted prematurely, I believe these events in as proof that human augmentation to the greenhouse effect had finally arrived Karolyoff, V. Jones and T. C warming in the CRU record 8.

C colder than that today. Halocarbons have an indirect effect because they destroy stratospheric ozone.

The greenhouse effect, combined with increasing levels of greenhouse gases and the resulting global warming, is expected to have profound implications, according to the near-universal consensus of scientists. For example, S. Weather station records and ship-based observations indicate that global mean surface air temperature warmed between about 0. McElroy in ibid. Projecting emissions. A third method for determining overall simulation skill is the model's ability to reproduce past climates or climates of other planets. The greenhouse effect, despite all the controversy that surrounds the term, is actually one of the most well-established theories in atmospheric science. One way is that when they break down in the atmosphere they produce another greenhouse gas. Indirect radiative effects[ edit ] The false colors in this image represent concentrations of carbon monoxide in the lower atmosphere, ranging from about parts per billion dark brown pixels , to parts per billion red pixels , to 50 parts per billion blue pixels.
