What are examples of existential threats?
Something is generally considered an existential threat when it is massive in scale, such as climate change or nuclear warfare. An existential threat can be a threat to something that isn’t actually alive, such as the future of a business or technology.
Will global warming cause extinction?

What is the most likely way humans will go extinct?
Synthetic virus. With millions of deaths chalked up to natural viruses like smallpox, influenza, coronavirus, HIV and Ebola, it’s unsurprising that experts see an engineered virus as one of the key existential threats to humans.
How long do we have left to live on Earth?
Fortunately, you don’t need to put your affairs in order any time soon. The researchers estimate that the Earth will remain habitable for another 1.75 to 3.25 billion years.
Who is the world’s number one polluter?
China
Top 10 most polluting countries 2022 The three countries with the highest CO2 emissions are: China with 9.9 billion tonnes of CO2 emissions, largely due to the export of consumer goods and its heavy reliance on coal; The United States with 4.4 billion tonnes of CO2 emitted; India with 2.3 billion tonnes of CO2 emitted.
Where is climate change the worst?
The Germanwatch institute presented the results of the Global Climate Risk Index 2020 during COP25 in Madrid. According to this analysis, based on the impacts of extreme weather events and the socio-economic losses they cause, Japan, the Philippines and Germany are the most affected places by climate change today.
