And finally, are there any other possible explanations for the apparent global warming?
Several questions continue to nag researchers in the climate community. If man were to attempt to reduce carbon dioxide emissions would it actually do any good?
Once that is complete, the old site will no longer be available.
Thank you for your patience and continual support of Reasons to Believe.
But, is it caused by man and can anything be done about it? Supreme Court is being asked to rule on a suit which demands that the Environmental Protection Agency regulate the release of carbon dioxide as part of its air pollution responsibility. And because the effects of global warming are so small compared to the global average, great care must be taken to avoid bias in collection and analysis of the data.
Environmental activism to reduce carbon dioxide emissions has reached a new intensity. The president is being heavily lobbied to subscribe to the Kyoto Protocol which would require the U. to emit less carbon dioxide than it released in 1990. Many pitfalls in this process have already occurred which have produced a lack of confidence in the results.
This increase in CCN, in turn, appears to create more low-level clouds which cool the Earth.
When the Sun is quiet the GCR intensity striking the Earth is reduced, allowing the Earth to warm.
It is unclear whether global warming is due to increased carbon dioxide concentration or if carbon dioxide concentration is the result of global warming.A book and a movie with the titles, He makes the case that man's actions in burning fossil fuels are projected to increase the concentration of carbon dioxide in the atmosphere to the highest levels in history. I determined to take another look at the evidence and see if I could detect any recent trends in the atmosphere, ocean, and cryosphere which would seem to support the concept of global warming, choosing to select several small data sets.He insists that uncontrolled releases of carbon dioxide will eventually melt the polar caps completely, raising sea level and inundating many coastal communities like New York, Miami, New Orleans, and Los Angeles; and drastically changing agricultural patterns because of redistribution of temperature and precipitation. The data sets I used are limited in spatial and temporal scope making them relatively easy to analyze without bias.And, the Arctic sea-ice extent has decreased about 5% over the past 25 years.Note, within the general trends, however, shorter period oscillations occur.
