In other words, while many people and scientists were skeptical a couple of decades ago, virtually everybody today is convinced that global warming is a genuine and serious problem. In fact, even giant oil and gas companies, such as BP, Shell, and Exxon are no longer global warming skeptics...
Earth is getting slightly warmer year by year. It's not really warming up noticeably—at least not in the short term. In fact, since 1900, the whole planet has warmed up only by around 1.1 degrees Celsius.[1]By the end of the 21st century, however, global warming is likely to...
Global warmingis a term used to describe the contemporary increase in the average temperature of the Earth's atmosphere and oceans. Although local temperatures fluctuate naturally, the rising trend that is known as “global warming” can be separated from historical and/or pre-historicalclimate varia...
Examines the science and arguments of global warming skepticism. Common objections like 'global warming is caused by the sun', 'temperature has changed naturally in the past' or 'other planets are warming too' are examined to see what the science really

The theory of global warming is shown inFig. 1. Infrared radiation comes from two sources: the sun and the earth's surface. CO2absorbs a small fraction of the infrared radiation and re-emits it in a random direction. If there is more CO2, the radiation is absorbed closer to the source...
According to the Intergovernmental Panel for Climate Change 4th Assessment Report, global warming is unequivocal and the costs of inaction will result in aggregate costs for future generations. The impacts on coastal systems in the future are certain to be overwhelmingly negative, identifying small isla...
“geo-engineering, the deliberate large-scale manipulation of an environmental process that affects the earth’s climate, in an attempt to counteract the effects of global warming.” This involves various mechanisms to remove carbon from the atmosphere on a large scale or reduce the amount of ...
The young in each country have a nonstorable endowment of output,y. The young derive a “little bit” of utility from consuming their endowment; but they would really rather consume output when they are old (i.e., they really value the output produced by the next generation of young peopl...
But a team led by a University of Washington atmospheric scientist has used satellite data in a new and more accurate way to show that, for more than two decades, the troposphere has actually been warming faster than the surface. The new approach relies on information that better separates rea...
