What Is Physics? Science is built up with facts as a house is with stones. But a collection of facts
is no more a science than a heap of stones is a house.

Earth's response to CO₂ underestimated
This image shows the temperature response of the Earth (in °C) to an increase in atmospheric carbon dioxide from pre-industrial levels (280 parts per million by volume) to higher levels (400 parts per million by volume). Image (a) shows predicted global temperatures when processes that adjust on relatively short-term timescales (for example sea-ice, clouds, and water vapour) are included in the model (b) includes additional long-term processes that adjust on relatively long timescales (vegetation and land-ice).
