" Scientists warned of the dangers posed by unrestricted burning of fossil fuels in the 1860's"
 
Your statement implies that a consensus of scientists recognized the threat of climate change in the 19^th century when in fact it was the work of one John Tyndall.    The main concern at that time, in England, was the burning of coal which produced very high particle pollution.
 
“ Tyndall discovered that water vapor and carbon dioxide absorb and radiate heat, making them an important part of keeping the Earth warm and announced the culmination of his work at a Discourse at the Ri in 1861, going on to produce a book in the same year publishing his findings.”

“The health hazards of atmospheric pollution have become a major concern in Britain and around the world. Much less is known about its effects in the past. But economic historians have come up with new ways of shedding light on this murky subject.  In the early industrial age, Britain … depended almost entirely on one fuel source: coal. Coal supplied domestic hearths and coal-powered steam engines turned the wheels of industry and transport.

In Britain, emissions of black smoke were up to 50 times higher in the decades before the clean air acts than they are today. The great London smog of 1952, that prompted policymakers to act, killed 4,000 in the space of a week. But even that was not as dramatic as what went before.

Unregulated coal burning darkened the skies in Britain’s industrial cities, and it was plain for all to see. But air quality was not measured and monitored until well into the 20th century. And while soot blackened buildings and clothing, the effects of toxic air on health were not assessed, until recently.”
