The greenhouse effect makes part of the upper atmosphere cooler and less dense, reducing the drag on space junk that ultimately causes it to burn up.

The Independent · Study says climate change will even make Earth's orbit a messBy Seth Borenstein

On August 23, 1856, history should have been made. In a packed hall at the American Association for the Advancement of Science (AAAS), a groundbreaking paper was presented—one that identified the greenhouse effect three years before John Tyndall.

But there was a catch: the scientist behind the discovery, Eunice Newton Foote, was a woman. And history erased her.

All four answers are at least slightly true, but only (b) captures the most important aspect of how GHGs work. Greenhouse gases absorb and then re-emit electromagnetic radiation at specific wavelengths, particularly in the infrared spectrum. This slows the rate at which outgoing infrared radiation travels upwards from the earth's surface. For the other answers:
(a) It's not correct to say it's "trapped" in the lower atmosphere, in any but the most vague sense - the heat still flows upwards, just more slowly.
(c) GHGs *can* absorb some of the sun's energy (at specific wavelengths), but that's tiny compared to the effect on outgoing long wave radiation.
(d) GHGs do store energy when their bonds vibrate, but so do all molecules. That's how temperature works.

The stakes are far higher.

#ClimateBreakdown is with us. We can see the impact in every country.

If you went to school in the ‘80’s onwards you learnt about the #GreenhouseEffect.

But it is only in the past 2 decades that there has been a focus on STEM subjects.

It is the older generation who are betraying their children with their lack of understanding. I don’t blame them, but I do blame the right-wing media and successive governments that kept state educated children subordinate.
