“Is our climate changing? The succession of temperate summers and open winters through several years, culminating last winter in the almost total failure of the ice crop throughout the valley of the Hudson, makes the question pertinent. The older inhabitants tell us that the Winters are not as cold now as when they were young, and we have all observed a marked diminution of the average cold even in this last decade.” - New York Times June 23, 1890
“The question is again being discussed whether recent and long-continued observations do not point to the advent of a second glacial period, when the countries now basking in the fostering warmth of a tropical sun will ultimately give way to the perennial frost and snow of the polar regions” - New York Times - February 24, 1895,.
It is probably helpful to distinguish between normal climate change and pollution. We may not be able to influence the former, except by way of being prepared for it, but we do need to find ways to reduce environmental damage due to pollution, for example excess plastics in the ocean.
