It's politics, not science, driving climate mania: Why are environmentalists and scientists so reluctant to discuss long-term increases in southern hemisphere sea ice?

For years, computer simulations have predicted that sea ice should be disappearing from the Poles.
Now, with the news that Antarctic sea-ice levels have hit new highs, comes yet another mishap to tarnish the credibility of climate science. Climatologists base their doom-laden predictions of the Earth’s climate on computer simulations. But these have long been the subject of ridicule because of their stunning failure to predict the pause in warming – nearly 18 years long on some measures – since the turn of the last century. .....

It’s fair to say that this has been something of an embarrassment for climate modellers. But it doesn’t stop there. In recent days a new scandal over the integrity of temperature data has emerged, this time in America, where it has been revealed as much as 40 per cent  of temperature data there are not real thermometer readings. Many temperature stations have closed, but rather than stop recording data from these posts, the authorities have taken the remarkable step of ‘estimating’ temperatures based on the records of surrounding stations.  So vast swathes of the data are actually from ‘zombie’ stations that have long since disappeared.  This is bad enough, but it has also been discovered that the  US’s National Oceanic and Atmospheric Administration is using estimates even when perfectly good raw data is available to it – and that it has adjusted historical records. Why should it do this? Many have noted that the effect of all these changes is to produce a warmer present and a colder past, with the net result being  the impression of much faster warming."
