Here in Yosemite National Park the Lyell and Maclure glaciers have shrunk 78% since 1883. Hmmmm something is going on.
Of course something is going on. Nothing is static. Climate is changing all the time, as everything else is changing, as you are changing as you get older.
We are currently in a slight warming period
in relation to a previous colder period, know as the Little Ice Age.
Climate changes in big cycles, known as Ice Ages, and smaller cycles within those inter-glacial periods. Jesus Christ lived during a warm period, similar to today. The Dark Ages, prior to the Middle Ages, were miserably cold. The Middle Ages became warm again, enticing the Vikings to emigrate to Greenland, but that warmth lasted just a few hundred years, and was followed by the Little Ice Age.
We are now in another warm period, similar to the warmth during the life of Jesus Christ. We should rejoice.
