Earth Warming?

Question

I'm concerned as most other people when it comes to global warming. So it is believed that carbon dioxide has a major affect on the earths warming but what about other factors that maybe even bigger than CO2. Ever layed in a field with green grass under a shady tree on a hot summers day and felt cool? But when on the city street surrounded by tarmac and sitting under a man made bus shelter on a hot summers day it is stinking hot still?
Well its the natural evaporation from the grass and trees that cools the air around the tree. Across the world urban sprawl is huge removing the trees and grass (earths natuarl air conditioning system) laying tarmac, tiled and tin rooves all which retain heat.
So should we be looking at better reflective surfaces for our buildings?
Ones which reflect radiation rather than absorb it?
painting roads white and having white rooves on all the buildings and houses around the world might have a greater effect than reducing CO2.

Also trees are the earths lungs so could the rise in CO2 be comming from the lack of trees (due to urban sprawl and timber logging) to filter out the high levels of this gas from the atmosphere.
Some rediculous amount of the Amazon has been destroyed. Should we be also be more concerned with planting more trees than reducing CO2 emissions?

Answer 1

CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.

Look at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest, and 2006 is shaping up to maybe break that record.

How's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.

There has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.

Yes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up.

Just to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.

Answer 2

Hi. Anything which reduces CO2 would be good for slowing climate change. I am quite concerned about plankton as this is a major player in absorbing CO2 and emitting O2. Pollution and the increase of UV can really hurt. The other ideas are self evident except painting things white. This may not reduce the re-radiation of infrared which would still be trapped by greenhouse gases.

Answer 3

while/If each and all of the ice melts the earth is going to be too warm for many manufacturers to advance everyday customers wont have manufacturers to consume they'll die,then theres no nutrition for secondary customers they die and final the tertiary customers can combat one yet another yet there all going to die at last.additionally Polar bears and different animals interior the arctic have shrinking properties they mandatory the ice yet people are destroying all of their properties.it somewhat is not basically affecting animals yet people too all of it somewhat is inflicting the water to upward push and it somewhat is inflicting floods, all human beings is dropping their properties and others are ineffective.
