I am a climate scientist and geologist and think that climate, geology, and geography are incredibly interesting fields that people deserve to know more about. If you have any questions that you’ve sat with for a while, are just curious, want to know more about future or past scenarios, or even have worldbuilding questions, feel free to ask!
Recently (past couple years) we've started getting tornado warnings where I live and have even had like 2, is that linked to climate change?
It's also been way drier in that time and we have burn notices when we used to be so bad with humidity
Certainly it’s either a result of climate change, bad record keeping, or both. Without knowing vaguely where you are though it’s impossible for me to give you a potential explanation as to how/why, since tornadoes are very complex meteorological processes that typically require a few special conditions to form.
Pennsylvania, east coast of the US
Ah ok! So first read the “Topography” section of another comment I made on this post. There I explain what “Tornado Alley” is and how tornadoes form.
These conditions can technically exist in many places, but North America specifically has the perfect set of conditions. As climate is changing, Tornado Alley has made a sharp shift eastward over the past 100 years. It used to be mostly located over Texas, Oklahoma, Kansas, and Missouri, but has since been pushed to be mostly over Kentucky, Tennessee, Mississippi, Alabama, and Georgia. Likewise, all of the corresponding elements that result in tornadoes have become more prevalent in the surrounding areas, including a few stray systems from the Midwest potentially reaching into Pennsylvania.
Pennsylvania is also in a pretty interesting spot to watch, especially eastern Pennsylvania, because during correct conditions mid-summer through mid-fall, you can get an usually strong and consistent build up of hot, moist air from the coast trapped up against the mountains in the center of the state, and then an overlying cold airmass from up north. When met with atmospheric instability, these can create conditions necessary to spawn tornadoes.
Thank you for the explanation!
This sucks so bad for me though
You’re probably just going to have to worry mostly about way hotter summers
