An IT student is walking along with his bike when another IT student walks up to him and goes “Nice bike. Where did you get it?”
The first student says, “The other day, this beautiful woman ran up to me with this bike, threw it on the ground, ripped off all her clothes and said ‘Take anything you want!’”
The first student says, “So I took the bike”.
The second student says, “Good choice. The clothes probably wouldn’t have fit”.
Ozone holeIn 2000, NASA data showed the hole at just under 11 million square miles, the biggest it had ever been to date. Record low temperatures in the stratosphere are believed to have helped the expansion of the ozone hole during the southern hemisphere's spring season. Antarctic ozone depletion starts in July, when sunlight triggers chemical reactions in cold air trapped over the South Pole during the Antarctic winter. It intensifies during August and September before tailing off as temperatures rise in late November of early December. Depletion of the ozone layer over Antarctica and the Arctic is being monitored because ozone protects Earth from harmful ultraviolet radiation. By 9 Sep 2000, the hole had grown over Chile, exposing a populated city for the first time. A larger hole was recorded on 24 Sep 2006.Image, compiled from NASA's Total Ozone Mapping Spectrometer instrument onboard the Earth Probe satellite, reveals how the ozone hole (in deep blue) has extended as far as southern Chile. |
