We don't know what we don't know. About ice sheets and if the world is heating up or heading for a mini ice age.
What we do know is that our senses (when they are working properly) tell us about danger sometimes. Decay and bacteria that goes with it are detected by repugnent smells anmd even revolting stuff to look at.
I know California is as polluted as a cesspool by the smell. It smells like fire, crap, old bad water. I smell Iowa and Nebraska and ugh! Feed lots.
Maybe some pollution could be limited if we planted trees around huge animal holding pens-and honeysuckle vines would be nice.
All I know is the sprays we use everyday in our home and the spraying on farms gets into the soil and causes cancer in the next generation. Will all our trash and plastics production heat up the world. I don't know, but if it does we may not have anything but a disease ridden planet left anyway.

What seems to be being missed here is that this is NOT a one issue right or wrong subject. You CANNOT say whether climate change is happening or not based on one years data. You just can't. Anyone who says they can is lying or stupid.

The danger of climate change is in the unknown effects of single changes on complex systems. For example the danger of the icecaps melting is not (or at least not just) rising sea levels. It s also the potential interruption of ocean currents by changing salinity levels. It is also the potential damage to phytoplankton/algae etc that could catstrophically affect the whole food chain. And all tese things link to a thousand other things.

The real danger is of a snowball effect - ie a number of small changes snowballing into an epic catastrophe.

Climate change is happening. Full stop. It's effects and whether or not it is man madeare open to question - as is what should be done about it.

But it is happening.

Good points, cellularsociety. Are you a student of earth science?
Just curious.
BTW, Welcome to Political Wrinkles.

I'm not but I soon will be. I am shortly to begin an 'open university course' that I hope will eventually lead to a degree in geosciences in the long run.

For now though I'm just a committed amateur.

Thanks for the welcome.

Climate change is happening...........Duh! that's why it's called CLIMATE instead of PERMANENT. How many times in Earths history has it changed even long before man or his machines?

By the way the LAST rise in temperature was 1997 since then it has been going DOWN.

To all you members of the "global warming" religion I must remind you about the oldest of computer acronyms GIGO (garbage in, garbage out)......in other words if your DATA is wrong your conclusions are invalid.

nature is far more powerful than man will ever be

Now, now, now people... the politically correct term these days is Climate Change... afterall, global warming is the root cause of all of this climate change!


The liberal mindset defies logic.

Well here in west Michigan today the global warming climate change has been falling at the rate of one to two inches an hour since early this morning.

My ice makes my tea overflow if it melts. I don't know if that's what it is supposed to do or not according to physics. Perhaps most physics majors are men who never had to clean up after themselves.

If your tea is overflowing you are defying all the laws of science because ice is less dense than water....that's why it "floats". The only ice that sinks is if you make it from "heavy water" and is radioactive. You need to check your ice as you are slowly dying from it if makes your glass overflow when it melts. Perhaps it's only the condensation on the outside of your glass that is deceiving you.

Test this yourself......fill glass with tea....add ice till level reaches rim.......wait.....ice melts......level actually goes DOWN.

Extra points........hot air holds more water vapor.......if air at 90 degrees is at 90% humidity and temperature drops...what happens........RAIN...water is released.....air at 40 degrees has 100% humidity (fog) temperature goes up.....fog disappears because it is now water vapor and invisible as only 90% or less humidity.

Basic science disproves almost every "theory" that the "warmists" are foisting on you. Like CO2 being the problem.....NOT. Water vapor has 50,000 times the influence of CO2 on temperatures and man is only responsible for less than 3% of the CO2 in the air anyway.

I'll take your word about the iced tea. I don't have time to sit and watch ice cubes melt. And with the economy the way it is-waste not want not, ya know?
And I am not a "warmist". But I do have an open mind about it. And I do think we are polluting the heck out of our planet. The main change we ought to endorse, IMHO, is lower birth rates. Of course, we would have to issue less work visas and do something about our illegal problem.
Educating women has proved to help reduce birth rates. Where women are not oppressed, you see more sensibly sized families for the resources available.

The only problem with your "birth control" plan is that the ONLY people restricting the size of their families are the intelligent ones and the "socially conscious"........thus you would be "dumbing down" the gene pool and the result would eventually be the loss of civilization itself due to the development of 2 different classes of people.

China already has such a policy........we on the other hand do not allow "nature" to "thin the herd" (we actually feed and support everyone even if their family is to big to support itself and becomes a drain on our society).

Nature is such a pesky thing......especially when man keeps trying to "overrule" it's immutable laws with "good intentions".
