Consider the 2 °C average global atmospheric temperature rise as discussed by the IPCC. Assume an oven with an the interior that is a perfect cube having a volume of one cubic meter, empty of everything except air. What would be the temperature inside the oven if the energy represented by said 2 °C global warming were instead applied to the atmosphere inside the oven?
The problem I'm trying to solve is to make climate change understandable to friends and family.
We talk about trying to limit global warming to 1.5 °C (if that's even possible any more) or 2 °C. The problem is that 1.5 °C or even 2 °C doesn't sound so bad on a local level. The temperature goes up and down by that much every day from one sunrise to the next. Some days it's so cold that a 2 °C rise would be welcome. What's wrong with a little warming?
What's wrong is that it just seems like a little warming; it's actually a lot of warming spread out over a large area or volume; it's really quite a bit of energy.
To illustrate the amount, suppose we confined it to the volume of an average domestic kitchen oven, say, a cubic meter to make it easy.
That's my question.
For the brief period of time that the oven would continue to exist.
