In popular science journalism the latest is always the best. With all the explanations for the “pause” in global surface temperatures since 1997 – there are now over 30 of them – it is always the most recently published one that is the “answer.” This time it’s the Atlantic Ocean that’s to blame. A paper published in Science says that a 30-year periodicity warms and cools the world by sequestering heat below the ocean’s surface and then releasing it. You don’t have to look very deeply at the science to realise that, despite the headlines, no one has come up with an answer to the “pause.” --David Whitehouse, The Global Warming Policy Foundation, 26 August 2014
