Earth’s oceans are warming at a remarkable rate. Over ninety percent of the atmospheric heat humans have generated in the course of the past decades has been absorbed by Earth’s oceans. The consequences for oceans and atmosphere have been dire, and promise to play out over centuries, regardless of what we do.
Long before the ‘intractable conflict’ between Israeli Jews and Palestinians gets resolved, climate change will have thrown everything up for grabs — literally. It already has.
It’s the ultimate green dream: some device or substance that can capture the sun’s infinite flood of energy, store that energy, release it as heat and electricity — in controlled fashion — then absorb it all over again in a continuous closed loop. A little organic molecule called norbornadiene promises to make dreams come true, in the crucial realm of home heating and cooling.

Stuart Franklin is turning air miles into trees. Franklin — the founder of a carbon offsetting project in Ecuador — calculates how many seedlings he needs to plant to capture the carbon dioxide emitted by tourists jetting to the Galapagos Islands each year.
Once upon a time, the US was the world’s top emitter of carbon dioxide. The average American still emits more than the rest of us, but – sometime last year – China’s annual emissions surpassed the US’s. As the Chinese choke on fume-filled air, their leaders are turning to the wind.
