climate change, part 2: human impact

i know, the title of this almost sounds like a Hollywood action blockbuster. no? really? what if you replaced the 'human' with... oh, never mind.

anyway, before i continue to the human impact of global warming, here is a pic that depicts the damage human civilisation has done to the world.

as you can see, climate change is definitely one of the three things we should be worried about, but biodiversity and the nitrogen cycle are things that we should give much more attention. for anyone that doesn't know, our manipulation of the nitrogen cycle has caused areas of the sea to be devoid of life, due to algal blooms.


now, on to the human impact on the natural process of climate change.
the amount of greenhouse gases that human civilisation emits into the atmosphere, compared to the amount emitted by natural processes, is very, very small.

however, this doesn't mean we're not doing any damage, because it all adds up. it can be described the same way as scientific progress: 'on the shoulders of giants.'

in science when one person makes a momentous discovery, it is usually due to the discoveries made before him, without which he wouldn't have the knowledge or the tools/techniques to do anything.
so, while we make a small contribution to greenhouse emissions, it may still be enough to have an effect, however a small one.

as the pic above shows, we're barely doing anything to tip the scales askew in the cycle of climate change, let alone send it crashing into reverse within a few days, as the media often portrays.
i think we have a comfortable amount of time to change our greenhouse emissions for the better, no need for alarmist mass media scare shows about how we're all going to die horribly. we have easily enough time to let the nature of technology to run its course, the development of more efficient, less polluting technologies.

by the time our civilisation has the potential to destroy the climate change cycle with our current technology, we'll have moved on to other technologies, both more ecological, efficient, and probably cheaper.

so, don't worry about climate, or global warming, or whatever its called now. I'm not really sure how to put it in simpler terms, but i really shouldn't have to.

also the Australian carbon tax = stupidity. its only going to drop world temperatures by 0.01* over 100 years, at $900 a year to each taxpayer. even if we did need a drop in temperature, the gains mean nothing, for a very large loss. i could understand if it was 1*, but 0.01? its just the government pretending to do something, for votes.

if you read this and part 1, i hope you gained something from this. and if you have any questions, don't hesitate to ask. if you want to defend the carbon tax, don't hesitate to.

http://cruxcatalyst.blogspot.com/2010/04/earths-nine-life-support-systems.html - here is a blog that has copy pasted, some of it at least, on nitrogen and biodiversity. the global warming article is very informative as well,

http://www.newscientist.com/article/dn18577-earths-nine-lifesupport-systems-climate-change.html -here it is. to get the whole nine life support system bit:

i keep all of these on just in case some don't work for you.


remember how i asked if you wanted to see a dog riding a unicycle? well, here's a pic drawn by waveh on deviant art, of two dogs riding a unicorn. in my book, this is close enough to get cigar.

OK, so its a robot unicorn. and i personally don't like the look on the smaller dogs face, or the larger one for that matter. anyway, enjoy.
