the temperature has risen 1 degree and man had caused an increase of one degree. that means that no other cause can have caused it.
this means one of two things
1) all the hundreds of temperature changes in the last 5 billion years have been flukes.
or
2) man has somehow managed to find a way to prevent any of them from having any effect on the world without even knowing it.
in addition, Global mean the entire world, not just in places. England has a lot of road, homes etc. that cause a local increase in temperature. how many roads do you think there were paved pre 1950 how many concrete buildings and ground coverings were around then. population around the world has more than doubled, how much of it in England. People raise the local temperature too.
the solar activity (just to name 1) is on a high note on at least two of its cycles. one is a 11 year cycle, which would come and go. another is an 88 year cycle which is near the top. 50 years ago, it would have been near the bottom. another is a 200 + cycle (last time i discussed this, i did not know of this one) which has not yet peaked but is suppose to soon. that would mean that 50 years ago it was quite a bit cooler. Claiming that man is the only cause is nothing but trying to get attension. Man has had much effect, but there is indications that his very presence has done the majority of it, not his output of co2. That might be doing some, but there is no proof yet that it is, and certainly not that its the entire culprit.
The earth has survived having much higher levels of co2 and temperatures before, with most living things adjusting. By claiming that we are ruining the planet, you claiming that we are doing something to the planet it cant survive or that the human race is not as adaptable as other creatures.
