Climate Change

Video: A video report on the predicted climate shifts.

The mean annual climate of the average location on Earth will slip past the most extreme conditions experienced during the past 150 years and into new territory by between 2047 and 2069, depending on the amount of climate-warming greenhouse gases that are emitted during the next few decades, a new study found. The study, published Wednesday in the journal Nature, used a new index to show for the first time when the climate — which has been warming during the past century in response to manmade pollution and natural variability — will be radically different from average conditions during the 1860-2005 period.

The study shows that tropical areas, which contain the richest diversity of species on the planet as well as some of the poorest countries, will be among the first to see the climate exceed historical limits — in as little as a decade from now — which spells trouble for rainforest ecosystems and nations that have a limited capacity to adapt to rapid climate change.

This year has been a bloody one for firefighters on the front lines against wildfires. With climate change intensifying fires, it may be time to change the way we fight them.

We usually measure wildfires in acres burnt or the number of homes destroyed. But there’s a human toll to fires as well. So far this year 32 people have lost their lives fighting fires, the highest number in nearly 20 years—and the fire season isn’t done yet. More than half of those deaths occurred in a single incident, when all but one of a 20-man firefighting crew were killed during the Yarnell Hill fire in Arizona in June.

We know the oceans are warming. We know they are acidifying. And now, to cap it all, it turns out they are suffocating, too. A new health check on the state of the oceans warns that they will have lost as much as 7 per cent of their oxygen by the end of the century.

The cascade of chemical and biological changes now under way could see coral reefs irreversibly destroyed in 50 to 100 years, with marine ecosystems increasingly taken over by jellyfish and toxic algal blooms.

"The emergence of the global warming problem creates an imperative for action that cannot be ignored." – The Environmental and Energy Study Institute's Board of Directors' unanimous statement, 1988.

In the past quarter century, the case for action has become ever more pressing, and the latest report by the Intergovernmental Panel on Climate Change (IPCC), a scientific body under the auspices of the United Nations, adds yet more urgency. The IPCC, first set up in 1990, has become the world's leading scientific authority on climate change.
