...assessments in 1995 and 1990), made a dramatic shift from their earlier, more conservative stance as a result of five years of intensive research compiled by teams around the world. This report placed the onus for the trend squarely upon the shoulders of a society whose reckless burning of fossil fuels has altered the earth's atmosphere and contributed substantially to the observed warming over the last 50 years...
Your article on rising temperatures and the thinning of Arctic sea ice was an eye opener. It is time to realize that deposits of fossil fuels are nature's garbage dumps and that we need to think seriously of ways to cease using this garbage in our biosphere. To convert futile complaints about greenhouse gases into positive action, we should free all non-fossil-carbon energy technologies from taxes for five or even 10 years of active production and sales. There is nothing like the lure of no taxes to stimulate businesses to come up with creative solutions to "insoluble...
Yours was one of very few articles in the nonscientific press that discussed the natural component of global warming. Indeed, according to the data derived from ice cores, it appears the earth keeps cooling and warming by itself and has done so since long before fossil fuels started being burned by humans on a large scale. Unfortunately, most people think global warming can be reversed if other sources of energy are used. This is a gross oversimplification. We should use our resources not to find ways to stop this natural phenomenon, but rather to discover ways to adapt...
Partly in response to this deadlock, NASA climatologist James Hansen last week unveiled an alternative strategy. Instead of pursuing the politically unpopular goal of drastically reducing consumption of fossil fuels, he suggests going after other greenhouse gases, such as methane, which he thinks has accounted for as much warming as carbon dioxide in the past century, even though it is present in the atmosphere in much smaller quantities...
...possible to avoid some climate change this century, up or down--and there's still a chance that the earth's systems will compensate for any that occurs--but the possibility that climate turns rapidly and unpredictably should spur us into doing whatever is practical to turn from fossil fuels--fast. If done right it can be a boon. Energy conservation usually increases profits. In developing nations it's often cheaper to use alternatives like wind power to electrify new areas...
