The BBC has rounded up the top ten climate-change denialist arguments with pithy, reasoned rebuttals. The Earth is getting hotter, it's our fault, and it's a problem. What we do about it is up for debate, but those three facts are as close to a scientific consensus as you can come.
3. THE EARTH HAS BEEN WARMER IN THE RECENT PAST
The beginning of the last Millennium saw a "Mediaeval Warm Period" when temperatures, certainly in Europe, were higher than they are now. Grapes grew in northern England. Ice-bound mountain passes opened in the Alps. The Arctic was warmer in the 1930s than it is today.
There have been many periods in Earth history that were warmer than today - if not the MWP, then maybe the last interglacial (125,000 years ago) or the Pliocene (three million years ago). Whether those variations were caused by solar forcing, the Earth's orbital wobbles or continental configurations, none of those causes apply today. Evidence for a Mediaeval Warm Period outside Europe is patchy at best, and is often not contemporary with the warmth in Europe. As the US National Oceanographic and Atmospheric Administration (Noaa) puts it: "The idea of a global or hemispheric Mediaeval Warm Period that was warmer than today has turned out to be incorrect". Additionally, although the Arctic was warmer in the 1930s than in the following few decades, it is now warmer still.
Where are our petabyte drives? Brian Hayes takes us through the reasons storage is “stuck” in the low terabytes. The tl;dr is that we got such exceptional capacity growth in the late 90s and early 00s we don’t need much more right now, so the focus since then has been on SSDs, networking, interfaces, etc, […]

3D printing has been one of those “next big thing” innovations among early adopters and the tech circle in-crowd for a few years now. However, the prospect of creating your own three-dimensional objects is still in its relative infancy with the general public. While the idea itself is fascinating to most, high prices and the […]
White hat hackers get paid to find holes in their own employers’ online systems, and plug those holes before they become serious security risks. It’s a job that pays handsomely…mostly because few job candidates, even experienced IT professionals, have the skills to scamper over firewalls and infiltrate the deepest recesses of a battle-tested network. But […]
