When world leaders gather in Copenhagen on Monday for negotiations on a new agreement to combat the threat of catastrophic climate change, their success or failure will ride on economics, not environmental science. Theoretically, the two-week conference will focus on limiting the heat-trapping gas emissions blamed for global warming. But its major debates will all [...]

BBC News Three UK groups studying climate change have issued an unprecedented statement about the dangers of failing to cut emissions of greenhouse gases. The Royal Society, Met Office, and Natural Environment Research Council say the science underpinning climate change is more alarming than ever. They say the 2007 UK floods, 2003 heatwave in Europe [...]

Some countries in the world are more worried about global warming than others. The Maldives, for example, might be drowned by rising sea levels. And Nepal fears being flooded by melting mountain glaciers. I wrote recently about their governments meeting in unusual places to highlight their common plight.

The Maldivian President is asking nations most vulnerable to climate change to take the lead in reducing global warming. The leader of a country threatened by rising sea levels slammed rich countries at a two-day conference for doing too little to prevent climate change. Maldivian President Mohamed Nasheed says countries like his that are most [...]

By Art Reckinger Irreversibility and Irrevocability tend to be bothersome words. They imply that no matter what is done, there is no return. Global Warming is due to increasing Carbon Dioxide (CO2) and is raising the world temperatures, irreversibly. The world ice masses are melting more rapidly every day, and the melt appears Irrevocable. Susan [...]

A U.N. conference in Copenhagen next month is due to agree a new pact to combat global warming after mounting evidence that human activity is disrupting the climate. The following is a timeline of the discovery of global warming. 300 BC – Theophrastus, a student of Greek philosopher Aristotle, documents that human activity can affect [...]

People often talk as if warming temperatures are the only evidence of human-induced global climate change. But the amount of carbon dioxide in the atmosphere also has increased dramatically. For most of the past 800,000 years, atmospheric carbon dioxide concentrations ranged from about 180 to 280 parts per million. Today, it is 387 parts per [...]

Ernest Hemingway must be reaching for a bottle of grappa in his grave. The snows of Kilimanjaro—inspirations for a Hemingway story of the same name—could be gone by 2022, a new study confirms. The ice atop Kilimanjaro “continues to diminish right on schedule for disappearing, unfortunately, in the next couple of decades,” said glaciologist Lonnie [...]
