Nah, used to when I was young and idealistic. Bothered me alot. Made me feel bad. Got over it. Feel better now.

Today I heard on NPR that 2 years ago 10% of the world's coral was dead. It's now 27%! It's been looked at extensively and the overwhelming evidence points to warming. For example, corals grow producing coral growth rings which can reflect growing conditions. Looking at these rings and counting back thousands of years shows current El Nino's at twice the historic rates. These are currently much more frequent than ever before. These are also likely to be more extreme as well. >You may take some comfort in that for every scientist >advocating a concern for global warming, they're is >another scientist who says there is no such thing That is simply not true. Much has been learned about the problem in just the last 5 to 10 years and the evidence really is overwhelming. The scientests that I have heard speak on global warming strongly have refuted this equality of proponents. You will now be hard- pressed to find a reputable scientist that won't admit that it now appears likely that global warming is here. >>....

Dispite our best efforts, these forests are not back in anywhere near historic levels. Once this ecosytem is disrupted, it will take a long time to recover (unlikely in several lifetimes). >> I use a push mower and put in an ecolawn. > >What is an ecolawn? It's a lawn mix developed here at Oregon State. It has numerous unobtrusive wild flower seeds mixed in with grass seed. It gives a nice texture to a lawn and requires much less watering. http://www.nicholsgardennursery.com/store/dept.asp?dept%5Fid=80&mscssid=W07C 1QJUVSS12MNX000GQ3U2QHX6C2W2 At 02:26 AM 12/9/00 -0800, Tom wrote: >> kevin_at_yourplanetearth.org wrote: >> ...I personally feel a lot of guilt >> > from driving all the time to go kayaking, and I >> wonder if any others on this >> > list feel the same way? > >Nah, used to when I was young and idealistic. >Bothered me alot.

But, I also don't like sticking my head in the sand. To bring this back to seakayaking, we need to do as much as we feel comfortable doing and then do a little more still. I plan to paddle along reefs from time to time and hope that they are here for millions of more years. Unfortunately, the masses in this country don't show much will to manage problems until crisis strikes. And government is always two steps behind the public. Serious, sensable ecologists have been marginalized by conservatives and industrial spinmasters. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

Corals are very sensitive to changes in temperature because of their physiological nature. A living coral is a symbiosis between two organisms, coral polyps which build the coral, and an algae called zooxanthellae which produce the chemicals that allow polyps to build their limestone skeletons. Unfortunately, zooxanthellae have a very narrow temperature range in which they can live, often as narrow as 0.5 degrees C. When temperatures rise beyond their allowable range, they die off, and the coral reef is bleached (turns white). This is a dead reef. Bleaching is not always permanent. El Nino events often cause bleaching, but the zooxanthellae can repopulate the reef after El Nino has gone away. This kind of bleaching and repopulating has been observed many times. Unfortunately, global warming does not go away from year to year. A reef that is bleached from global warming related temperature rises is permanently dead. And since zooxanthellae are so sensitive to temperature changes, coral is an excellent indicator of global warming. That 25% of the reefs have recently died is a pretty good indicator that global warming is happening. For more info on coral bleaching, there are several articles about this on my website: Glossary explanation of coral bleaching: http://www.yourplanetearth.org/terms/details.php3?term=Coral+Bleaching An article on the 25% of coral reefs already bleached and 70% may be bleached by 2050: http://www.yourplanetearth.org/article.pl?sid=00/12/12/0123204&mode=nested An article about new institutions created to preserve coral reefs, including Clinton's creation of coral reef national monument in Hawaii: http://www.yourplanetearth.org/article.pl?sid=00/12/05/1933222&mode=nested If you like coral reefs, or have never seen one (such as me), go see them soon before they are gone!
