I am pleased with fuzzy logic's fuzzy logic. He makes some nice points and screws up royally on others...human.
He lays out the argument for me....we humans have way less impact ( lasting ) on this planet than the popular opinion of this last decade.
EVERYTHING changes....constantly yet you want to blame humans...not all.... just Republicans....for wrecking this lovely planet. Stop waving your arms...... the planet is fine....and will be fine regardless of the way humans live their little lives.
You may not like my opinion but it has as much validity as the doomsday prophesy....which always seems to be around the next corner.....watch your step !
Pull your head out and breath some fresh air...take a look at the sunshine. It is nice in one part of the world and it is not nice in another....it is cold for some hot for others.....you will not pass laws to stop this.
We human have had a huge impact on this Earth starting with the introduction of wet agriculture almost 10,000 years ago. One of the reasons this interglacial period has been so stable climate wise in relation to previous ones is probably due to the effect of methane introduced into the atmosphere from rice a taro cultivation in the east. It has buffered us from some of the fluxations seen in the climate records, but this has limits.
CO2 is the most important persistent
greenhouse gas and is strongly absorptive in the 14 micron band, right in the main curve of the EM spectrum emitted by the Earth, it isn't absorptive in the shorter wavelengths that make up sunlight. The result is a growing radiative imbalance that has to result in the warming of the overall global system and past records show us what happens when the Earth goes through rapid warming events, the seas can turn anoxic and create the perfect conditions for sulfur loving bacteria which give off hydrogen sulfide, a poisonous gas.
Oceanic anoxic events or anoxic events occur when the Earth's oceans become completely depleted of oxygen (O2) below the surface levels. The similar term euxinia refers to anoxic conditions in the presence of H
2S hydrogen sulfide. Although anoxic events have not happened for millions of years, the geological record shows that they happened many times in the past. Anoxic events may have caused mass extinctions. These mass extinctions include some that geobiologists use as time markers in biostratigraphic dating. It is believed oceanic anoxic events are strongly linked to lapses in key oceanic current circulations, to climate warming and greenhouse gases.
We're currently responsible for emitting over 10 billion tons of CO2 every year, something that isn't really all that "natural" in the sense that no other life form on the planet has had such a significant effect on the atmosphere in such a short period of time. Since the mid 1800s CO2 levels have gone from about 280 ppm to almost 400 ppm. In slightly more than 150 years we've had the same effect that it took natural systems thousands or even hundreds of thousands of year to create, are you seriously claiming that as humans we get some sort of ecological waiver that allows us to anything we like with no negative effects.
The world is going to be around, but if human activities continue on the same or worse pace then many species simply won't be part of the natural world and that most likely won't include us when you consider how frail human civilization really is and how dependent most people are on modern conditions to survive.
The Dow Jones doesn't monitor the actual physical health of the planet, something some people have a very difficult time accepting, things like the Dow and other indexes don't even reflect economic health as we've seen repeatedly over the last several decades. And yet the naysayers keep claiming we're on some path to materialistic glory if we just keep doing the same thing over and over again. Einstein had an interesting observation for people who do that and I think it applies equally well to entire societies that choose faith in unsupported beliefs over hard evidence.
