2020 was a year with health crisis's and natural disasters, forcing everyone to adapt to new realities.
Ahead of us in 2021, are many shared challenges on an economic, geopolitical, social and climatic level. It'll also be a year with shared knowledge.
Let's take a brief look back and also a look forward into next year.
The future of the coronavirus pandemic will largely depend on two things, according to experts:
The strength of immunity people build against the virus after being exposed, and how the vaccines will be effective.
In Europe, based on solidarity, there'll be a vaccine for everyone and there's a recovery plan for the revival of economies.
New American President
In the US, the Trump era ends, and Joe Biden's era will begin.
The new President-elect has arduous tasks: to keep a pandemic under control that has claimed hundreds of thousands of lives and to heal a country torn by racial violence and protests.
Biden has promised to rejoin the Paris Agreement on his first day in office.
The accord sets out a global framework to limit global warming to well below 2°C and pursues efforts to limit it to 1.5°C
It's hoped that in 2021, the European migration pact will encourage member states to be more supportive of each other to avoid the concentration of immigrant populations and to strengthen the fight against illegal immigration.
Global recovery is unlikely in 2021. It'll take much longer to recover fully from the shock caused by the coronavirus pandemic than initially expected. That's according to the warning from the president of the European Central Bank. Christine Lagarde also stressed the danger of protectionism.
And we will begin to see the start of the impact of Brexit on the European Union. Britain will finally leave the EU on 1 January.
They'll be new rules for businesses, trade and British people living in the UK and abroad.
So let's look at the calendar for next year.
