Depends on what your mining,coal mines have very little slack after processing but gold and other mineral mines are a different story but improvements have been made since the old days before we knew how dangerous mercury and arsenic was.
Most mines arent profitable when the strip ratio gets higher then 7 to 1 unless it's a very rich deposit like gold.
You're right, they don't. Sedimentary analysis as part of reconstruction of past temperature in the Arctic (not just sediment, but ice cores, tree rings, and other assorted proxies) show that we were progressing towards another ice age. But that stopped when humans began influencing the planet.
Here's their figure 3c:
The caption for this figure:
Mean of all records transformed to summer temperature anomaly relative to the 1961–1990 reference period, with first-order linear trend for all records through 1900 (green line), the 400-year-long Arcticwide temperature index of Overpeck et al. (2) (blue curve; 10-year means), and the 10-year-mean Arctic temperature through 2008 (red line). Gray lines encompass T2 standard errors of the proxy values as evaluated for each 10-year interval.
Oh no, we can't? We've eradicated a deadly human disease, we've cured many others, the Dutch live below sea level, we created acid rain with sulphuric emissions which destroyed fish populations, the ozone hole won't fully recover for decades yet, and we're acidifying the ocean with our emissions of carbon dioxide, not to mention the climate effects. We can and do fight mother nature, and many times we win.
Most science is completed using research grants...they don't make the authors rich, they pay for the grad students, equipment, and cost to present that data at conferences, etc. The committees who give out the grants want to see where the money goes. It's not lining the Ph.D's pocket.
I spent 22 years in the coal mines in BC so I dont have to,it's actually the silica in the rock that causes black lung,not the coal.The silica is jagged and like a barb so once it's in your lung tissue it is there for life. The harder the rock the higher the silica content and most hanging wall rock in B.C.'s coal mines is moose mountain sandstone,in the underground it was the rock dust they laid on the ground to stop explosions and the dust from drilling roof bolts and hanging wall.
The rock causes silicosis.
Tonington,I mean you cant fight mother nature when she wants to have another ice age,a meteor impact could trigger one,and we may have cured some viruses but more keep popping up.
As for research grants,I guess you have to take the good with the bad but from some of the stuff I have seen on drowning polar bears(they can swim for days) and melting arctic ice(happens every spring) i have to sometimes shake my head.
My last few years in Nunavut I read many papers and talked to many people and what I read and heard about the polars was totally opposite from what I see and hear at home in the "world" so that's what gets my goat.
I never saw many researchers up there in 3 years,none to be exact except the Government guy that was head of studying them at Churchill and the rest of the eastern arctic.I had supper with him in camp and his consensus was the bears were doing fine.

Like I said,a meteor impact or couple volcanic eruptions could happen,something a graph wont show,all our records are but a mere blip in the big scheme of things.
Ice ages arent predictable,if they were cyclical there would be the exact same thickness of rock inbetween coal seams and we were mining 11 different ones,each seam represents an ice age.There was no conformity on times.
Ridiculous! Make up your mind! You cannot have it both ways: knowing and not knowing what nature can do.
Whatever you mean, you're wrong. Ice ages start out with growing ice in the polar regions. This is brought on by slight orbital changes. The change in incoming solar radiation isn't enough to produce an ice age. There needs to be a change in the albedo (growing ice sheets) as well to bounce more of the reducing incoming solar radiation back into space. If you look at the figure I placed in the text above, it's clear that this was beginning to happen. But it's abundantly clear that the dominant mode changed. And now we have a warming Arctic, with ice retreat. Manmade signal in this case dwarfs the signal that leads to an ice age.
Sure, an asteroid could strike us, but that is not part of the somewhat regular cycle of glaciation and de-glaciation.
This guy claims the last ice age came very quickly. Do the sediments lie?
