The fifth IPCC assessment report published in 2014 highlighted the fact that humans are the main cause of global warming and provided an overview of the current and projected global impacts of climate change. The IPCC AR6 WGII report updates these findings and additionally puts a special focus on the regional and sectoral impacts of climate change, making it a very valuable resource for regional and national adaptation planning.
The world population of youth, within the ages of 10-24 amounts to1.8 billion in a world population of 7 billion people, as documented by the UNFPA state of world population 2014. The effect of the emergence of a large population of youth depends on the manner in which a government regards their youth, which could either be as a liability that demands more resources or as problem solvers and change agents of the future.
After 3.000 years of largely unchanged global mean sea levels (GMSL), the oceans have begun to rise from the 20th century onward, encroaching higher and higher onto the coastlines of continents and islands and threating the livelihoods of millions (if not billions) of people. The reason for this is twofold and directly connected to the global warming caused by increasing greenhouse gas concentration in the atmosphere: the water warms up and expands (thermal expansion), and the higher temperatures cause glaciers and ice shelves (primarily in Greenland and Antarctica) to melt.
