Weren't the same people who are concerned with global warming the ones that said we were going into an ice age in the 70's?
Were they? Surely these people must be past it by now?
Examine this publicly available article; I offer no recommendations, just that it attempts to be fair and is cited. It is risky to confuse historical and geological timescales, and ultimately, we are all going to die (JMK?)

The idea of global cooling in the 1970s was a hypothesis based on limited scientific evidence at the time. However, it was not widely accepted within the scientific community. Today, the overwhelming consensus among climate scientists is that the Earth is warming primarily due to human activities, such as the burning of fossil fuels and deforestation. This warming trend is causing a range of impacts, collectively referred to as global warming or climate change. The scientific understanding of climate has evolved significantly since the 1970s, based on improved data, models, and research methods.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
