As we saw last week, the worldwide scientific community has reached consensus that global warming is inevitable if humans continue to dump "greenhouse gases" into the atmosphere at anything like present rates. Greenhouse gases include carbon dioxide, methane, nitrous oxide, chlorofluorocarbons (CFCs) and a few others. These gases act like the glass covering a greenhouse, letting sunlight in but...

Despite the growing scientific consensus about the risks of global warming and climate change, the mass media frequently portray the subject as one of great scientific controversy and debate. And yet previous studies of the mass public's subjective assessments of the risks of global warming and climate change have not sufficiently examined public informedness, public confidence in climate scien...

We evaluate the prospect of forming voluntary global warming agreements in which membership entitles a country to trade emission permits with other member states. To do so, we construct a calibrated general equilibriummodel that jointly describes the world economy and the strategic incentives that guide the design of national abatement policies. Countries choose their initial permit endowments ...

There is a growing divide in how conservatives and liberals in the USA understand the issue of global warming. Prior research suggests that the American public's reliance on partisan media contributes to this gap. However, researchers have yet to identify intervening variables to explain the relationship between media use and public opinion about global warming. Several studies have shown that ...

The study is motivated by the problem of stabilizing the concentration of atmospheric carbon, which is widely discussed in the context of global warming nowadays. A key difficulty in the design of stabilization strategies is the uncertainty of the underlying physical model. In the present paper, a general problem setting is suggested and a relevant alanytic framework elaborated. Analysis employ...

Human activities have greatly reduced the amount of the earth's area available to wild species. As the area they have left declines, so will their rates of speciation. This loss of speciation will occur for two reasons: species with larger geographical ranges speciate faster; and loss of area drives up extinction rates, thus reducing the number of species available for speciation. Theory predic...

BACKGROUND The establishment rate of invasive alien insect species has been increasing worldwide during the past century. This trend has been widely attributed to increased rates of international trade and associated species introductions, but rarely linked to environmental change. To better understand and manage the bioinvasion process, it is crucial to understand the relationship between glob...
