This annotated lecture presents three slides of observations on how the climate is changing. The perspective is on the fact that heat is accumulating in the environment. Much of the heat is stored in the oceans. Some of the heat is melting ice on the land and in the seas.
The heat also heats the air. The air temperature is what we feel, and it varies from day-to-day. If we look over a number of years we observe a warming trend.
We can, scientifically and objectively, attribute the warming, primarily, to the release of carbon dioxide from burning fossil fuels. Because we continue to release carbon dioxide, we know that in the next several decades heat will continue to accumulate and the Earth will warm.
We need to limit this warming.
We have to adapt to this warming.
