Climate change is the greatest threat to humanity. It has been in the top 5 biggest threats for humanity since 2011, but in a survey done by the World Economic Forum in 2017, it became the most likely risk. Climate change will have a huge influence on issues like food and water shortage, radicalisation and mass migration. Europe could see millions of migrants as the environment deteriorates.
According to a study made in 2017, there will be a massive rise in migration due to climate change. The rate of climate change now could lead to the amount of migrants in Europe increasing threefold by the end of the century. Bob Ward, who is the policy and communications director at the Grantham Research Institute on Climate Change and the Environment, at the London School of Economics and Political Science, said that the results of the study must be taken seriously. He also mentions how badly climate change will affect Europe: “Hundreds of millions, perhaps billions, of people will be exposed to coastal sea level rise and shifts in extreme weather that will cause mass migrations away from the most vulnerable locations.” According to Ward, this could lead to conflict and wars.
The places with the most migration by 2050 are predicted to be Sub-Saharan Africa, South Asia and Latin America, according to a report done by the World Bank Group in 2018. These areas could be dealing with tens of millions of migrants due to lack of water, crop decline, rising sea-level and surges of storms. This could lead to a human crisis. The World Bank Lead Environmental Specialist Kanta Kumari Rigaud claims that the migrants moving from rural areas to cities could encounter new and threatening dangers. She mentions the consequences of this: “We could see increased tensions and conflict as a result of pressure on scarce resources.”
However, it does not have to be like this. If immediate action is taken, the number of migrants could go down by more than 100 million, or 80%. The World Bank Chief Executive Officer Kristalina Georgieva recommends cities to develop the possibilities for education, training and jobs to assist with the arrival of migrants. Other things that can be done to help the situation are to reduce the emission of greenhouse gases, to alter improvement planning to take into account the climate migration cycle and to invest in the understanding of internal climate migration.
Mass migration will become a great issue, if nothing is done to try and prevent it. Tens of millions of people will migrate to escape extreme weather conditions and lack of food and water. Immediate action needs to be taken to significantly lower the number of migrants. If nothing is done, consequences could include conflict and wars.
