What doesn’t change with climate?

Posted by Ari Jokimäki on March 8, 2013

Global warming and subsequent climate change have a lot of different effects. The composition of the atmosphere changes. The troposphere swells and the atmosphere gets wetter. Oceans warm and expand. There are chemical changes in the ocean waters. Well known example of that is the ocean acidification caused by the increasing carbon dioxide concentration.

The biosphere gets shuffled. Some species shift to other places looking for more suitable conditions in which to live. Body shape and/or size changes for some species. The timetables between species get all mixed up. For example, because of an earlier spring the available food (caterpillars) is gone before the eggs of migratory birds hatch. Some, or according to predictions quite many, of the species will even go extinct.

Glaciers and ice sheets are melting. There are changes even in the lithosphere when the pressing weight of the ice sheets and glaciers is reduced as they melt into the ocean. Today at some places we can still see this same effect at work as the Earth’s crust is uplifting because the weight of the ice sheets that were there during the last glaciation (i.e. the “ice age”) was removed when the ice melted away. This effect also affects the asthenosphere, a viscous layer below the lithosphere.

So the climate change shows up everywhere – in the atmosphere, hydrosphere, biosphere, cryosphere, lithosphere, asthenosphere, and beyond. Is there anything within Earth’s system that doesn’t change with climate?
