In the blue

In the early 90’s I gathered five slides with a common blue aesthetic of snow landscapes in order to be submitted for a contest. I was not conscious yet of the consequences of the earth warming in the coming years.

Recently I read that rising temperatures will change the colour of the world's oceans, making them more blue in the coming decades. Scientists found that increased heat will change the mixture of phytoplankton, tiny marine organisms in the seas, which absorbs and reflects light. There will be less of them in the waters and this will drive a change of colour in more than 50% of the world's seas by 2100.

Since 1980, a significant global warming has led to glacier retreat becoming increasingly rapid and ubiquitous, accelerated since 1995 and affecting in a dramatical way the glaciers in the mid-latitudes as in the Pyrenees and Alps. Assuming that the current ablation rate remains constant, It is expected permafrost and the glaciers of the Pyrenees could disappear around the middle of the 21st century.

Are we still on time to preserve our blue?
