Here are 5 climate facts to keep in your back pocket:
- Over 97% of climate scientists agree that climate change is driven and accelerated by human activities.
- Climate cycles do occur naturally, but nowhere near the unprecedented rate of change we are seeing right now.
- Even in small concentrations carbon dioxide has a great impact on climate.
- Both water vapour and CO2 are greenhouse gasses but carbon dioxide has an important impact we can control.
- Natural phenomena contribute to climate change, but they are no longer the leading cause: humans are.
Before the Industrial Revolution, CO2 concentrations were 280 parts per million (ppm). Now, they are 419 ppm: likely the highest levels in 2 million years (7,15,16)
This warming is happening too rapidly for ecosystems and countries to adapt, thus increasing the risk of climate catastrophes with massive economic, environmental, and health costs (7,8).
