2)what sorts of data can we gather?
3)is there hard data available? can we gather it? locally? CA
4)what methods would you use to gather data?
1) You can't, unless you properly define it.
2) That hasn't been determined yet, although they are working on it.
3) The data that we have, mainly NASA and East Anglia, has been admittedly corrupted.
4) Well, that is still open. Several methods have been tried out and mysteriously when they didn't prove AGW they were abandoned. Take, for example, the Earth has been cooling for over a decade now. Even James Hansen and Phil Jones have had to admit as much. Yet CO2 level has risen during this time. That is concrete or chiseled in stone. Yet our most vocal environmental enthusiasts ignore that issue. If they are going to ignore that basic issue, what common ground can we ever have?
Quote by Chris Folland of UK Meteorological Office: “The data don't matter. We're not basing our recommendations [for reductions in carbon dioxide emissions] upon the data. We're basing them upon the climate models.”
When DATA does not matter, how can you logically and scientifically study the subject?
Tree rings: when trees are growing the add a ring, the size of the ring can be measured, by taking a sample of a tree ring (or simply use a tree freshly feeld) you can analyze the width oof a tree ring back: one ring = one year. Check the internet for it.
Pictures from the last 50 years from towns close to the "tree zone" taken over the last 50 years (in the Alp mountains there is a significant movement of the "tree lien": pictures of cottages shown 100 years ago show them with only grass around them, today you find trees and can see that the tree line moved up by appr. 200 meter/600 yards).
Simple (your teacher will not like it): go to a university and ask for their climate data .....
It would be rather hard to start now and gather data. You might get some idea about climate change by talking to people in their 70s about the changes they might have observed about the climate. As far as the whole earth is concerned, the article below describes the changes that are taking place in the Earth and why they are happening.
Asking the same question twice is very rude!!!!
1)how can we test climate change?
2)what sorts of data can we gather?
3)is there hard data available? can we gather it? locally? CA
4)what methods would you use to gather data?
