The US produces the most climate pollution per person, but China is now the world’s largest overall greenhouse gas emitter. But China’s economy is cooling off, and changing. The World’s Jason Margolis reports on what China’s new economy could mean for the health of the planet.
While the global goal is to limit future temperature rises to within 2 degrees Celsius (3.6 Fahrenheit) above the pre-industrial average, a recent report predicts that China’s temperature rise is likely to be more like 2.7 to 2.9 degrees Celsius (4.9 to 5.2 degrees Fahrenheit).
Beijing is experiencing its worst air pollution yet as heavy smog chokes the capital city for the fifth day. Schools are closed and residents are being told to stay indoors. All of this while President Xi Jinping is in Paris for the UN Global Conference on Climate Change.
Countries gathered at this week's global climate conference in Paris are trying to find ways to grow their economies while cutting greenhouse gas pollution. But there's one huge economy that's already doing it: California.
Iceland is — geologically speaking — a crazy place. The local language, for instance, includes a specific word to describe the phenomenon for a volcano detonating beneath a glacier and triggering a flash flood. And now climate change may be setting a new geological domino effect in motion, by melting some of those glaciers and increasing the chances of an eruption.
The US and the rest of the world failed to forge an ambitious plan to tackle the climate crisis six years ago in Copenhagen. Since then the crisis has only gotten worse, but going into the next global climate summit in Paris, President Obama's top science adviser John Holdren is hopeful that world leaders are finally ready to step up to the challenge of avoiding catastrophic climate change.
On Thursday, word came that ExxonMobil is being investigated for possibly misleading shareholders on the risks climate change poses to its business. On Friday, President Obama killed the Keystone XL oil pipeline to the US from Canada, citing the threat of climate change from burning fossil fuels. The oil business has seen worse weeks, but perhaps not many.
It's always been hot in the Persian Gulf region. But a new report finds that without action to limit climate change, the combination of rising temperatures and humidity will often push much of the region beyond the limits of human adaptability.
