From rising sea levels, to increasing temperatures, to wilder hurricanes and tornadoes, there are many different impacts of climate change, and they are becoming ever more frequent.
The consequences on the population of this planet? They are already underway.
According to UN predictions (IPBES - The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services), in the coming decades, almost a million species of animals and plants risk extinction, more than have ever been endangered throughout human history.
Move, adapt or become extinct: these are the three possible reactions to climate change.
Many species have already become extinct in the last few decades, and others are moving to different altitudes or latitudes, searching for new territories where the climatic conditions are similar to the ones they adapted to throughout their history. Some migratory birds are changing their arrival and departure dates year after year, plants are flowering earlier, mountain animals are pushing themselves, where they can, to higher altitudes. A few species, known as "mobile generalists", are compatible with many different environments, and can therefore move easily (for example foxes and deer); instead, for many others, moving is not a good solution: some are unable to do so fast enough, or they cannot find hospitable areas they can reach from where they currently live.
And then there is the human race, probably the most adaptable on the whole planet, equipped with our extraordinary ability to get by, which is a fundamental aspect of survival.
