“…as a scientist I was trained you always have to show the negative data, the data that disagrees with you, and then make the case that your case is stronger.” -Richard Muller
Global temperatures have been on the rise not just for decades, but for as long as we’ve been measuring temperatures around the globe: for more than a century. Recently, however, the temperature has spiked to an unprecedented high, similar to what we saw in 1998.

It isn’t due to global warming, on its own, that temperatures are so high this past year. Instead, it’s a combination of long-term climate change and also short-term weather patterns, like El Niño. When the short-term variations change again, we can expect to see a “pause” in the warming again for another 13-15 years, but this will not mean that global warming has stopped!

Be prepared for what the science is going to see, and don’t let yourself be taken in by unscrupulous arguments ever again! (This one is for you, Denier!)
