What is Climate Change? | Start Here

Climate change is a pressing crisis, with world leaders under pressure to take concrete action. The spike in carbon dioxide levels during the industrial revolution is mainly caused by human activity such as burning fossil fuels and increased global population. This has led to the 'Greenhouse Effect,' trapping heat in the earth's atmosphere and causing rapid warming.

Climate change is already happening, leading to extreme weather events and natural disasters. Europe is colder than the Arctic, and millions of people are facing food and water shortages. The rising sea levels due to warmer temperatures pose a significant threat.

Melting ice sheets and glaciers are adding trillions of tons of freshwater into the oceans, causing people to lose their homes. If this continues, millions more will be displaced, and coastal cities like Miami in the US or Osaka in Japan could be underwater within 80 years.

Entire island nations in the Pacific are at risk of disappearing due to natural disasters and droughts. The Paris Agreement aims to cap temperature rise, but global CO2 levels continue to increase, with some major polluting countries failing to set ambitious targets or pulling out of the agreement. Despite positive momentum in renewable energy projects and public transport initiatives, experts emphasize the need for a significant shift in how we run our world.
