Current Weather Events
Zimbabwe, December 2019- Victoria Falls, the world's largest waterfall dries up.
Australia sees it's most widespread bushfire season in 2019-2020
Storm Ciara and Dennis work together to flood towns and villages across the UK in February 2020.
Using data from December for the last 41 years, the Arctic has lost about 1.9 million square kilometers of sea ice.
In the last 50 years, we have lost 17% of the Amazon Rainforest to Deforestation.
The earth’s average temperature keeps rising over time. The graph opposite shows how throughout time, the temperature has got higher and higher.
Despite scientists agreeing that climate change has been made worse by humans, some people believe that the warming we are seeing today is natural. After all, the climate has changed throughout history. Sometimes the sun gets hot spots which emit more heat for a few years.
Sometimes the earth spins and orbits in such a way that the earth is closer to the sun for a while, meaning that the earth warms up. These are called the Milanković Cycles.
And throughout history, these cycles and sunspots have caused the temperature to change.
However, scientists are very clever and are able to predict how much the sunspots and the Milanković Cycles will change the Earth’s temperature. The amount that the planet is warming is more than they have predicted using the sunspots and the Milanković Cycles alone. Something else must be causing the rest of the warming!
The global temperature has gone up when there are more greenhouse gases in the atmosphere. The global temperature has gone down when there are fewer greenhouse gases in the atmosphere. The graph shows the average temperature of the planet in red and the increase in carbon dioxide (CO2) in blue. As the amount of carbon dioxide goes up, so does the temperature! Notice how the Carbon dioxide and temperature levels have both gone up much more since the industrial revolution in the 18th century!
Our job is to stop that black temperature line from getting any higher.
