 Well, that concludes the second week of Denial 101x. This week we examine the many indicators that global warming is happening. Kevin Cowton debunked myths about the surface temperature record and showed us how to check that the temperature record is reliable. Robert Way debunked myths about glaciers, with a closer look at what's happening in Greenland and Antarctica. P.S. Shaneamon looked at how sea level is rising at an increasing rate, and Peter Jacobs dove into the semantics of the phrases global warming and climate change. Looking at the many independent lines of evidence, a clear picture has formed that global warming is happening. That leads to the next logical question, what's causing global warming? That's what we'll explore next week. Spoiler alert, we're causing it. Gavin Corley will use jelly beans and his bank balance to explain the carbon cycle, while Andy Schuess looks at carbon dioxide emissions from volcanoes. Mark Richardson will explain the greenhouse effect in a way only an Englishman can, using cups of tea. Lastly, Sarah Green and Dana Nuccitelli will explain in more detail some of the human fingerprints being observed in our climate. Again, we'll feature more of the world's leading climate scientists explaining the science and debunking the myths related to what's causing global warming. We hope you've enjoyed the second week of Denial 101X. Once again, we encourage you to share what you've learned so far, any questions you have, and your first thoughts about next week's topic, the role that humans are playing in recent global warming, on the weekly wrap up discussion forum. The forum is where you can find out what your fellow students think about this week's topics and also see what's going on in their part of the world related to climate change. So we look forward to seeing you again next week.
