No matter where we live, we all experience weather: how the conditions of our atmosphere change over minutes, hours, days, weeks. We also all experience climate: the weather of a place averaged over several decades. Climate change is when these averaged conditions start to change and its causes can be either natural or caused by human activities. Rising temperatures, variations in rainfall, increased extreme weather events are all examples of climate changes, but there are many others. Back in 1990, the first report by the Intergovernmental Panel on Climate Change (IPCC) concluded that human-caused climate change would soon become apparent but could not yet confirm that it was already happening. Now, some 30 years later, the evidence is overwhelming that human activities have changed the climate. https://www.ipcc.ch/report/ar6/wg1/resources/external-resources/
