Read here and here. As more and more of these temperature data manipulations are coming to light, it's obvious that the "unprecedented" worldwide global warming is the result of unprecedented worldwide scientific dishonesty. Look carefully at the chart below and note how the original, raw data blue curve is well under the "adjusted" Swiss temperatures, the red curve (click on image to enlarge). As a comparison, take a look at this chart, which C3 created using global "adjusted" temperatures. On the right, below, is an animated image from Brisbane, Australia showing how much its raw temperatures have also been heavily adjusted to create warming out of cooling.
