I've been thinking about this for very personal reasons. Tracking the changes and looking at the models should be useful in selecting locations for working and living. You might be able to determine where the best economic growth will be, the most stable/liveable climate, etc. This is all in addition to the simple usefulness to societies and governments in planning for global changes which may be massive and will undoubtedly be extremely expensive.

Scientists work on map of climate change

It's funny you should mention climate change--

The emissions from the eruption and other volcanic activity of Mt. Pinatubo in 1991 were way beyond any man made pollution in the entire history of mankind.

The cycle of global warming and global cooling will continue in spite of man.

The next ice age is overdue.

"There are three main types of evidence for ice ages: geological, chemical, and paleontological.Geological evidence for ice ages comes in various forms, including rock scouring and scratching, glacial moraines, drumlins, valley cutting, and the deposition of till or tillites and glacial erratics. Successive glaciations tend to distort and erase the geological evidence, making it difficult to interpret. It took some time for the current theory to be worked out.

The chemical evidence mainly consists of variations in the ratios of isotopes in sedimentary rocks, ocean sediment cores, and for the most recent glacial periods, ice cores. This evidence is also difficult to interpret since other factors can change isotope ratios. For example a major mass extinction increases the proportion of lighter isotopes in sediments and ice because biological processes preferentially use lighter isotopes and a reduction in biological processes makes larger quantities of lighter isotopes available for deposition.

The paleontological evidence consists of changes in the geographical distribution of fossils - during a glacial period cold-adapted organisms spread into lower latitudes, and organisms that prefer warmer conditions become extinct or are squeezed into lower latitudes. This evidence is also difficult to interpret because it requires: (1) sequences of sediments which cover a long time-span and wide range of latitudes and are easily correlated, (2) ancient organisms which survive for several million years without change and whose temperature preferences are easily diagnosed, and (3) the finding of the relevant fossils, which requires a lot of luck.

Despite the difficulties, analyses of ice cores and ocean sediment cores unambiguously show the record of glacials and interglacials over the past few million years. These also confirm the linkage between ice ages and continental crust phenomena such as glacial moraines, drumlins, and glacial erratics. Hence the continental crust phenomena are accepted as good evidence of earlier ice ages when they are found in layers created much earlier than the time range for which ice cores and ocean sediment cores are available."

Wow you remember the sixties?

They say that if you remember the sixties, you weren't there.

But I was there.

Let me clarify my stance on this issue.

Pollution gas emissions etc. all need to be controlled and or eliminated for the sake of health, clean air and clean water are essential.

When I cite the clear evidence of the eruption of Mt. Pinatubo as a cause of recent Global temperature increase, nobody counters. That's fine.

People need to be rational rather than emotional on this issue. Everyone wants the US to stop polluting and then give India and China a pass these are not solutions. The US has done much (maybe not enough) to curb pollution. What programs have India and China adopted?

Lately the news is harping on the snow in Colorado, that's news? It's winter it's supposed to snow in Colorado. It would be news if it didn't snow in Colorado.

Look at the reactionary crap that goes on with the EPA and others trying to "protect the environment". They added that stuff to the Gasoline in New England, (some four letter acronym), it was supposed to decrease the fumes going into the atmosphere, meanwhile the stuff seeps into the soil and pollutes the ground water.

The the snow from the streets in Boston can't be dumped into the harbor without being treated, so they put it on trucks and haul it miles away, I'm sure the exhaust from the trucks is much les damaging than the snow would be to the harbor, (the snow is cleaner than the harbor).

These are only two examples of reactionary Environmental Protection policies.

I am waiting for the proposal to put scrubbers on Mt Saint Helens.

I think you need a scrubber. Who is "everyone"? What reactionary comments ahve you seen on this thread?

Try talking to the people in this conversation, not your imaginary foes.

Pinatubo is a non-starter: the overall effect of volcanic eruptions is cooling, not warming. Choosing one chemical out of a veritable soup of them is nonsense. And when the effects of that one are negated by the overall effect, well, you're getting into silly space. If you know so much on this issue, you shouldn't have wasted the post on pinatubo at all.

Besides, the OP was about mapping climate changes, not determining causes.
