As the earth's temperature climbs, so does the threat of extreme weather events such as drought, wildfire, hurricanes and tornadoes — all occurring more frequently at higher strengths, according to climate scientists.

Two severely damaged homes are seen in a neighborhood in the aftermath of a tornado in Sullivan, Indiana, April 2, 2023.Simulations of the atmosphere indicate that, as global temperatures continue to rise, so do the chances that the "fundamental ingredients" for a severe thunderstorm will be present, Ashley said.

One year the Southeast may get slammed with tornadoes, while another year the activity could be concentrated further west, she added.

It's not so much that Tornado Alley will no longer apply to a large swath of the Central U.S., but that other regions are beginning to catch up to the tornado production rates that are more typical of the Central Plains, Houser said. An unusual aspect of the recent tornado activity is how far north lines of twisters are forming -- especially in what is traditionally a cooler season, Houser said. It is not common to see tornadoes in places like Iowa, Illinois and New Jersey in this time of year, she added.

But, they will probably never get to the point where they can predict with certainty when a tornado will form, namely because scientists "don't really have all of the full complete picture of what makes a storm produce a tornado," Houser said.

And their are still blind climate change denialists. The same ignorant deniers are trying to back pedal and claim is cyclic. I really dislike this ignorance and maliciousness.

One major volcano eruption from debunking all the greenhouse emissions caused by humans! Nothing wrong with being cleaner but that is a tiny part of the issue. Then there is tectonic plate movement that will disrupt human activity fast. The electrical grid safety is more serious

Global warming causes more heat at the poles and therefore an equalisation of the north south temperature gradient. Extreme weather becomes less likely under those conditions. That's why weather more extreme in the Little ice age.

No.... it's not changing. The jet stream fluctuates from time to time. It's not Climate BS.

No. Good grief. Tornadoes have no in fact been increasing, which is easy to check. *Bottom bar shows a greater number of years*. Tornadoes of all sizes are reported MUCH better now, too. This scare headline is result of a MODEL.

I agree that climate change is a serious issue and we need to take action to reduce our greenhouse gas emissions. Extreme weather events are not only damaging to the environment, but also to human lives and livelihoods. Thank you for raising awareness about this important topic.

Complete BS. This is misinformation and your account should be locked. Those are the rules.

Well I guess the world should put a foot down on the largest emitter of carbon emotions and force them to stop or stop trade all together. China produces more than almost the rest of the world and until you stop them there is zero reason for others to listen to your crap.

The increase in global temperatures has a cascading effect on our planet's weather patterns and can lead to devastating consequences. It's crucial to mitigate climate change and reduce our carbon footprint to prevent further harm to our planet and its inhabitants.
