From the New York Times 21/4/21
The science of climate change is more solid and widely agreed upon than you might think. But the scope of the topic, as well as rampant disinformation, can make it hard to separate fact from fiction. Here, we’ve done our best to present you with not only the most accurate scientific information, but also an explanation of how we know it.
- How do we know climate change is really happening?
- How much agreement is there among scientists about climate change?
- Do we really only have 150 years of climate data? How is that enough to tell us about centuries of change?
- How do we know climate change is caused by humans?
- Since greenhouse gases occur naturally, how do we know they’re causing Earth’s temperature to rise?
- Why should we be worried that the planet has warmed 2°F since the 1800s?
- Is climate change a part of the planet’s natural warming and cooling cycles?
- How do we know global warming is not because of the sun or volcanoes?
- How can winters and certain places be getting colder if the planet is warming?
- Wildfires and bad weather have always happened. How do we know there’s a connection to climate change?
- How bad are the effects of climate change going to be?
- What will it cost to do something about climate change, versus doing nothing?
