Extreme weather events & climate change

Climate change is like poking a hornet's nest with a stick, disturbing weather patterns and messing up rainfall. Expect more extreme climates and frequent, unpredictable weather tantrums, with floods, droughts, and storms becoming the new normal.

Dramatic consequences - a movie-like scenario

  • The Flood or Drought Exodus: Imagine a movie where 200 million people have to leave their homes due to floods or drought by 2050. Climate change is making this script a reality.
  • Storms on Steroids: Storms become more intense and frequent. It's as if they've consumed some super energy drink because of increased atmospheric energy.
  • The Big Dry Up: Places like the USA, southern Europe, and the Commonwealth of Independent States (CIS) could turn into giant sandboxes with reduced rainfall leading to widespread drought.
  • Thirsty Planet: A 2°C increase in temperature could leave up to 4 billion people parched due to water shortages.

Temperature terrors - like turning up the heat in a sauna

Up to 1°C increase At this point, Arctic sea ice might bid us a final farewell during the summer months. Wildfires and heatwaves become more common in subtropical regions like the Mediterranean, southern Africa, Australia, and southwest United States. And sadly, even the beautiful corals of the Great Barrier Reef won't survive.

 

Real-world example: Think of your ice cream melting under the hot sun. Now replace the ice cream with the Arctic ice, and you get the picture!

 

Up to 2°C increase It's like being stuck in the 2003 European heatwave, which unfortunately could become an annual affair. Southern England could start competing with the Sahara for summer heat records, reaching around 40°C. Agriculture yields drop, exposing half a billion people to the risk of starvation. In the aquatic world, ocean acidity caused by increased CO2 levels could lead to the extinction of coral reefs and thousands of other marine life forms.

 

Up to 4°C increase This is like a dystopian movie coming to life. The Arctic permafrost, a cold storage for greenhouse gases, could thaw, releasing methane and carbon dioxide. Polar bears might face extinction as their icy homes vanish. Melting Antarctic ice could cause sea levels to rise by another five metres, submerging many island nations.
