The main objective of the Paris Agreement is to limit the increase in global temperature to no more than 2°C, from its pre-industrial level, by the end of this century.

Earth day is celebrated because there are intelligent life on Earth. That easy. On planets, without thinking beings presence there is no possibility of celebrating anything since there is no one who can do it. Instead, in this little blue point lost in a corner of universe, which from millions of light year distances is [...]
Some scientists say that what is happening in Borneo is the largest and fastest man-made ecological catastrophe in human history. Greenland, with its 2,175,600 km2, is the largest island in the world; New Guinea, with 792,500 km2, is the second and Borneo, with its 743,330 km2, ranks third among the largest islands on [...]
