Throughout most of the 20th century some scientists, including the highly esteemed astronomer, Percival Lowell, were convinced there were canals on Mars. This delusion went so far that they published detailed maps in scientific journals. In 1969, photos taken by the Mariner spacecraft showed there were no canals.
Scientists can get it wrong.
A few months before the Mars photos arrived, The Observer in London published the first mainstream article about the Greenhouse Effect. The sky has been falling ever since. For millions of years, we've been in ice ages, with short, warm interglacial periods, lasting no more than 12,000 years. A cycle of about 100,000 shows up in the long-term record and 'our' interglacial has gone on now for 10,000 years, and we should be grateful for the Indian Summer in which we live. This warm period has led to human civilisation, as we know it.
