Extreme weather and climate change - What is the difference between weather and climate - Which extreme weather events are being made worse by climate change and which are not? - What is the role of natural climatic variation, such as the El Niño/La Niña cycle, in extreme weather? - Did climate change cause Hurricane Sandy (and why is that the wrong question to ask)? - How does climate change affect heat waves? - How does climate change affect droughts? - How does climate change affect wildfires? - How does climate change affect the chances of deluges or severe precipitation? - Does climate change mean more snow or less, worse snow storms or weaker ones? - How does climate change affect storm surge? - Is climate change making hurricanes more destructive? - What is Arctic amplification and how does it affect extreme weather? - Is climate change and/or Arctic amplification affecting extreme weather in the northern hemisphere? - Is climate change affecting tornado formation? - In a warming world, why do some winters still seem unusually severe? - 3. Climate science basics - What is the greenhouse effect and how does it warm the Earth? - Why are scientists so certain the climate system is warming? - How does global warming increase sea levels and what has been observed to date? - Where does most of human-caused warming go? - What fraction of recent global warming is due to human causes versus natural causes? - How certain are climate scientists that humans are the primary cause of recent warming? - How do scientists know that recent climate change is primarily caused by human activities? - Why has the climate changed in the past, before there were human-caused greenhouse gas emissions? - What are the climate system-s amplifying feedbacks that turn a moderate initial warming into a big ultimate warming? - Is the current level of atmospheric CO2 concentration unprecedented in human history? - Are recent climatic changes unprecedented? - Has recent human-caused climate change been occurring faster or not as fast as scientists predicted? - Is there a difference between global warming and climate change? - What are the sources of the most important human-caused pollutants that drive global warming? - How does deforestation contribute to warming? - What is global warming potential and why is it different for various greenhouse gases? - Why does the rate of warming appear to vary from decade to decade? - Has global warming slowed down or paused in recent years? - Can we reach a point where emitting more CO2 into the air will not cause more climate change? - Have we already crossed tipping points (points of no return) in the climate system? - 2.
