An increase in air temperature leads to an increase in evaporation as warmer air is able to hold more moisture. Incredibly, this means that since 1950, there is more moisture in the atmosphere to the tune of about 2 kg or 2 litres per every square metre of earth's surface. The total volume of water that has been evaporated is equivalent to twice the volume of Lake Erie - in other words, climate change has essentially boiled off Lake Erie twice over.
Every year, the climate records are being broken and the hottest years are always within the last several years, which is a sign that we're in the midst of profound shift. Traditionally, we have defined climate as the average weather for a 30 year period, with the latest period of 1991-2020 considered as the period of new norm by NOAA.
We often hear about the temperature increases caused by climate change. However, what we perceive as heat or cold is also affected by the amount of humidity in the air because evaporation through skin plays a large part of how we regulate our internal thermal equilibrium.
