In America the EIA's latest energy outlook projects a (gentle) decline in coal usage out to 2040. This is a pretty conservative government agency.
I really don't understand the obsession with coal.

Apparently it does cool the atmosphere though, so it's good against global warming.
In case it's not: particulates do indeed cool the Earth. This mitigates the warming effect of CO2 emissions to an extent. The problem is that particulates don't last very long in the atmosphere, whereas CO2 lasts centuries.
To maintain a constant level of cooling, you have to keep burning more coal, which steadily increases the atmospheric concentration of CO2, which steadily increases warming. Before long you'll have overcome the cooling effect entirely and will be on a steady path to increased warmth.
Whatsupwiththat.com is a notorious climate change denial site, and the second sentence in the Wikipedia page you linked says:
This hypothesis had little support in the scientific community, but gained temporary popular attention due to a combination of a slight downward trend of temperatures from the 1940s to the early 1970s and press reports that did not accurately reflect the full scope of the scientific climate literature, which showed a larger and faster-growing body of literature projecting future warming due to greenhouse gas emissions.
Also, if your goal is diversity, that requires me to consider one's cultural background before discriminating against them. Why wouldn't you do the same for masculine guys?
Specifically in the context of coal mining, while I appreciate that communities get built around it that doesn't mean it should be extended beyond wider economic and environmental sense. Coal mining is both dangerous and literally toxic for those involved, but somehow people not involved in it invoke its macho status.
Similar, in dating statistics it is very clear that women will preferential choose well earning men over low earning men. This pushes men in general to take high risk high reward professions.
Unless you redefine masculinity to include how people perceive and treat men you can't define it to be the causes for higher suicide rates and higher risk seeking.
People also have a habit of being very nostalgic about the coal industry. I never understood that. It's a pretty nasty dangerous occupation.
