Wow, you're just going to believe the radical leftists from China? By simply looking at a thermometer? 

Thermometers have a well known liberal bias dating back to the mid 1970s. If I used my Freedom Thermometer, which I purchased from Koch Industries™️, it'll tell you its a pleasant 71 degrees and the air is perfectly clean. 

In the extremely unlikely event mainstream science concludes the planet is rapidly warming leading to dire consequences, you better believe its not because of the actions of humanity. No sir. Any of the 96% of scientists who disagree are liberal hacks.

Clean coal technology has come so far. Thanks Kochs!

1932 and 1922 in Dallas had as much and more rainfall in a 24 hr period.  Were those man made climate change events too?

Rainfall risk is often characterized in terms of the 100-year rainfall event, which is an amount of rain over a given duration that has a 1% chance of occurring in any given year. If extreme rainfall amounts increase by just 20%, the 100-year rainfall event threshold is exceeded twice as often. So Texas’s 7% median increase in the 100-year rainfall amount between 1960 and 2017 corresponds to a roughly 30% increase in the frequency of heavy rainfall exceeding the older 100-year threshold.

Those events? I'm not sure. 

But the state of Texas - after enduring Hurricane Harvey in 2017 (causing $125 billion in damages, tied for most expensive on record), enduring record low temperatures in February 2021 and a subsequent power crisis, followed by the hottest summer on record in 2022, and so on - is facing a string of extreme weather events.  Flooding events like what that tweet referenced in Dallas is just the latest extreme weather events that are more common. 

Having any one of them occur in isolation isn't surprising - it happens, as you referenced. What is unusual is to break 100 year rainfall records, heat records, cold records, and other weather events all in the same 18 month period.

Texas is not alone: China is enduring the most severe heatwave ever recorded, the American southwest is facing a water crisis, etc. You do realize climate change caused by humans isn't exactly debatable, right? The question is how much have we caused and how bad will it get.

7 of the top 10 recorded 24 hr rainfall amounts occurred prior to 1960 and 6 of the top 10 snow amounts.   So why did this article make the cut at 1960?

Because that's when the trend started. The report didn't decide that, it's what the data shows. If you read the report, it goes through the variations in precipitation in Texas in great detail. Here's the conclusion from that section:

Based on projected temperatures and the dominance of the direct temperature effect on extreme rainfall, we anticipate an additional increase of 2%-3% in expected extreme rainfall intensity in 2036 compared to 2000-2018 and an overall increase of 6%-10% compared to 1950-1999. These changes in amount correspond to increases in the odds of extreme precipitation of 10%-15% and 30%-50%, respectively.

Maybe you thought they were only looking at data since 1960, but that's not the case. The report uses data going back to 1895 because that's when good modern temperature data started being maintained:

The National Centers for Environmental Information maintain very good analyses of monthly averages of daily maximum and minimum temperatures from 1895 to present throughout the lower 48 states. The annual average temperature in Texas over the period 1895-2018 exhibits year-to-year variations of 2 °F or more. Broadly speaking, Texas temperatures climbed gradually until the mid-1950s, declined until the late-1970s, and rose thereafter.

Precipitation and drought data also go back to 1895.

You generally look for an increase and consolidation of multiple global weather events before declaring it a climate trend. Professional climatologists have done this, but you may want to run your Dallas rainfall observations by them. Who knows what else those lazy bastards missed?

A majority of scientists believe it's a trend either generated or accelerated by 100+ years of carbon-fueled human industrialization. Some disagree or have reservations. Both anecdotal and scientific evidence suggest -- at the very least -- that it's a problem worth addressing.

If we could capture all the tears being shed in the football forum, I believe we could refill both Lake Mead and Lake Powell. Environmental crisis averted.
