global warming...can you believe it ?, page-37

re: global warming...i dare you!!! Global warming affects a few things from my understanding:

The average temperature rises. So, even if it's not very noticable that a 1 deg celsius increase has occured, all the plants notice it, and are sensitive to these smaller changes... so it affects their flowering and leaf falls, etc. Also, the evaporation rate goes up substantially with a 1 deg celsius avg increase in temperature. A 1 deg avg celsius increase is like taking the place you live in and moving it 100 km north (on our side of the equator of course).

In Australia we actually end up with drier soil, because, even though there will be more rain due to increased evaporation, that increased evaporation rate dries the soil out faster after it has rained (therefore changing current farming).

Number of days over 35deg in summer escalates ... this one's becoming increasingly obvious ... infact, it will tack on an extra 5 days over 35deg in February on average over the next 20 years ... eek!

Increased no. of cyclones. The no. of cyclones has been the same for thousands of years, and some how has just mysteriously doubled over the past 30 years.

Geographical change ... savanah becomes desert, and adjacent forest becomes savanah ... this is already happening in parts of NSW and Tasmania as well as in Alaska and Russia and many other places. Also the Barrier Reef is starting to change!

Obviously climate change ... how come Sydney and Perth suddenly need to build desalinisation plants, when, for years they've had an acceptable rainfall for water? Much of this has been blamed on these longer sustained periods with less rainfall which we have been mysteriously having for the past 5 years.
