Not that this should come as a surprise, but I am sure it will be denied.

Climate change is not only influencing extreme weather events, it's causing them

Extreme weather events that spanned the globe in 2017 have been directly linked to -- and in some cases were even caused by -- continued warming of the planet via human influence through greenhouse gas emissions, according to a new report.

For the second year in a row, the annual report from the American Meteorological Society found weather extremes that could not have happened without human-caused warming of the climate.
Second year in a row...so, that state of denial must be getting harder and harder to maintain.

Of course it will. Because everyone here has the same level of expertise as people who literally base their careers around researching climate science. /s

Don't think I have ever met anyone who denies the climate changes.
Why are you telling me what not to think? And, I could not care less who you ever met.

There are a few. But more important is whether they accept climate science.

No one here said it was. The op did say climate change causes extreme weather, however
Look here buddy, every time climate skeptics use cold weather to prove global warming is false, you Lefties use the "weather isnt climate defence".
But then when suddenly an extreme weather event happens, you dont hesitate to point to that as proof of climate change.

You can't have it both ways, sorry

The certain marker for nonsense.

And btw, temperatures have fallen​ since 2016.

". . . For the second year in a row, the annual report from the American Meteorological Society found weather extremes that could not have happened without human-caused warming of the climate. Advances in scientific modeling and additional climbs in temperatures are making the connection between global warming and extreme weather much more concrete. . . ."

Do you have any more recent information? That stops at 2014, 4 years ago.

Here:
https://en.wikipedia.org/wiki/Tornadoes_of_2017
This page documents notable tornadoes and tornado outbreaks worldwide in 2017. Strong and destructive tornadoes form most frequently in the United States, Brazil, Bangladesh, and Eastern India, but they can occur almost anywhere under the right conditions. Tornadoes also develop occasionally in southern Canada during the Northern Hemisphere's summer and somewhat regularly at other times of the year across Europe, Asia, and Australia. Tornadic events are often accompanied with other forms of severe weather, including strong thunderstorms, strong winds, and hail.

There were 1,522 reports of tornadoes in the United States in 2017,[1] of which 1,418 were confirmed. Worldwide, 36 fatalities have been confirmed worldwide in 2017: 35 in the United States[2] and one in Brazil. The tornado season in 2017 started exceptionally early, having the second most active January since records began in 1950, and one of the most active first quarters in recorded history. 2017 also had four high risks issued by the Storm Prediction Center, making this the most active in the sense of high risks since 2011, which had a total of five high risks issued throughout the entire year.

NOAA data seem to stop in 2014. This is recent.

May 23, 2018 - Residents of Tornado Alley have been treated to a relatively quiet year of tornadoes so far in 2018, with the number of reported tornadoes near a 13-year low. As of Tuesday, a preliminary 362tornadoes have been reported to the National Weather Service this year, barely more than half the average through that date.

At a glance, it appears we now swing from record highs to record lows. But that's just over the last few years.

Why are you telling me what not to think? And, I could not care less who you ever met.
No one, especially me, is telling you anything close to what you should think. It was a simple statement, the word "I" should have let you know it was relating to me, not you. But, as usual, you are over the edge with your imagination and creative reading.

Actually the trend line has been down for many years.

You'd never know that from reading the Washington Post:

A news search on Google for “Extreme Weather” finds this headline first one out of the box:

Extreme weather has made half of America look like Tornado Alley
Climate change may be confounding the jet stream and making trouble for everyone.
The Washington Post

The IPCC doesn't say Climate Change will produce more tornadoes, but the Washington Post
ignores that fact and wants you to believe that it does.

They can't help themselves.

Recent Tornadoes are Due to Unusually Cold Weather

May 29th, 2019I had an op-ed published at Foxnews.com yesterday describing the reason why we have had so many tornadoes this year. The answer is the continuing cold weather stretching from Michigan through Colorado to California. A persistent cold air mass situated north and west of the usual placement of warm and humid Gulf air in the East is what is required for rotating thunderstorms to be embedded in a strong wind shear environment.
The strong wind shear and warm advection provided at the “tightened” boundary between the warm and cold air masses is the usual missing ingredient in tornado formation, unlike Alexandria Ocasio-Cortez’s claim that a New Jersey tornado warning was somehow tied to global warming.
As has been pointed out elsewhere, a trend line fit to the number of strong to violent U.S. tornadoes has gone down from 60 in 1954 to 30 in 2018. . . .

In other words, the number of most damaging tornadoes has, on average, been cut in half since U.S. statistics started to be compiled:
Or, phrased another way, the last half of the 65-year U.S. tornado record had 40% fewer strong to violent tornadoes than the first half.
To claim that global warming is causing more tornadoes is worse than speculative; it is directly opposite to the clear observational evidence.

Media has always been driven to sell more with sensationalism. That's why it is not to be believed. I find it so ignorant that the warmers will use media outlets, known to sensationalize, as fact.

Anyone else remember the 1962 Columbus Day Storm?

There hasn't been one yet here in Oregon to top that one.

How "extreme" a weather event is said to be is largely based on the dollar amount of the damage caused and/or the number of people who suffer its consequences. In other words, an EF4 tronado in the middle of nowhere is less "extreme" (i.e. covered by the news media) than an EF2 tornado in a major city.

Perhaps that perceived change over time is mostly the result of more people living on the planet noting how "extreme" the weather's effects are than any actual change in "bad" weather events.
