Concern for global warming is not a new craze

It is 80 years since the first calculations showed that the Earth was warming due to rising greenhouse gas emissions. Some people argue that concern for global warming is a modern phenomenon. And that scientists and environmental activists invented these worries to raise awareness of rising greenhouse gases from burning fossil fuels. Why are we suddenly so worried about carbon dioxide (CO2) when just a few decades ago there was talk of a new ice age? In the same breath, they might also question how changes in the amount of CO2 in the atmosphere can really change the Earth’s climate.
