Imagine a world with scorching temperatures in the summer. Freak snowstorms in the winter. Dangerous wildfires. Powerful earthquakes. Rising seas.
For years, scientists have warned people about the dangerous effects of climate crisis. Now, many are warning that those effects are already here.
Climate crisis is caused when too many gases like carbon dioxide are released. This is often due to human activity, such as burning fossil fuels to generate electricity. The gases work like a greenhouse, trapping the Earth’s heat and raising its temperature. This, in turn, disrupts the Earth’s weather.
According to NASA, the average global temperature has risen by around 1C since the 1950s. This sounds small — until you learn that Earth was only four degrees cooler during the last ice age.
In 2015, world leaders pledged to limit global warming to 1.5C with the Paris Agreement. Last year, the UN said the world had just 12 years to keep that promise. Now, many schoolchildren are striking on Fridays to demand action, led by the teenager Greta Thunberg.
