If you go from 1916 1961, you get a different answer. We'll have to wait to see how this 'shakes out'.

Just when I think maybe you're coming around, and that perhaps my feeling that you're deliberately LOOKING for bad data to support your alarmist point of view may be wrong, you post something like this.

Yes, depending on where you start, the trend in tornado damage can be up or down. What does it matter? Damage levels are not an indicator of tornado intensity or frequency, but only where a few happened to hit. Considering the increase in built structures and their cost (even relative construction costs continue to rise), the trend should show an increase in costs. Early warning most likely saves lives, but it doesn't help the buildings and such in the path of the tornado. Oddly enough, what does help is the urban heat island effect, which creates a 'bubble' of warmer air, which tends to deflect tornadoes around big cities.

Even if you were to look at the intensity and frequency of tornadoes, any trends would be based on speculation and assumptions about how many tornadoes that can be detected and classified now, were not detected, and the ones that were, we can only guess at the intensity. It's the same issue that we have trying to compare hurricanes now and in the past - depending on what you assume, you can make the numbers come out any way you want them to.

I agree that the start and end points for straight line fits are important, they are very heavily weighted compared with the ones near the middle. If that were my plot I think binning them in 10 year bins would make for a more convincing trend.

I'm more interested to see how things are changing in 'real time'. There's no question that climate change could be a little 'blip' in geologic time, but I doubt it, and the changes are happening too quickly.

Dude. It's not the typo.

It's the attitude of 'that data looks bad for my argument, but I can make it look great for my argument if I pick an arbitrary cutoff'

That's pure intellectual dishonesty.

The long term geological data says basically, exactly this.

Why - because you read a huffpost article about a wildfire? Because it doesn't 'feel right' based on the narrative you have already decided to fully commit to?

Here we are. Intellectual dishonesty again.

It may not just be climate that we sh0uld be concerned about:

"People once believed the planet could always accommodate us — that the resilience of the Earth system meant nature would always provide. But we now know this is not necessarily the case. As big as the world is, our impact is bigger.

In research released May 31, an international team of scientists from the Earth Commission, of which we were part, identified eight “safe” and “just” boundaries spanning five vital planetary systems: climate change, the biosphere, freshwater, nutrient use in fertilizers, and air pollution. This is the first time an assessment of boundaries has quantified the harms to people from changes to the Earth system.

“Safe” means boundaries maintaining stability and resilience of our planetary systems on which we rely. “Just”, in this work, means boundaries which minimize significant harm to people. Together, they’re a health barometer for the planet.

Assessing our planet’s health is a big task. It took the expertise of 51 world-leading researchers from natural and social sciences. Our methods included modelling, literature reviews and expert judgement. We assessed factors such as tipping point risks, declines in Earth system functions, historical variability, and effects on people."

"But even now, with warming at 1.2℃, many people around the world are being hit hard by climate-linked disasters, such as the recent extreme heat in China, fires in Canada, severe floods in Pakistan, and droughts in the United States and the Horn of Africa."

As discussed FAIL. So 2 out of 5 ain't bad.

The problem is that maybe it's just a start.

The US may have some catching up to do...

"China has reached its goal to have more non-fossil fuel installed electricity capacity than fossil fuels earlier than planned, with 50.9% of its power capacity coming from non-fossil fuel sources now, Chinese state news agency Xinhua reported on Monday.

Back in 2021, the Chinese authorities said they would target renewables to outpace fossil fuel-installed capacity by 2025.
China is unmatched in renewable energy spending globally, investing in raising its solar and wind power capacity.

China’s wind and solar power generation has jumped in recent years to nearly equal domestic residential electricity consumption, but the relatively small share of household demand in overall consumption means that China still needs a lot of fossil fuels."

The kids will be the ones that will be affected.

"HELENA, MONT. - Rikki Held decided to join other young plaintiffs in a lawsuit to force Montana officials to do something about climate change after watching wildfires blacken the sky over her family's ranch, drought stress the cattle and violent floods erode the banks of a nearby river.
Held and 15 other young people finally got their day in court Monday after suing state officials three years ago for failing to take action to curb global warming. The case is the first climate change lawsuit to reach trial among dozens filed across the U.S. in the last decade.

They are trying to persuade state District Judge Kathy Seeley over a two-week trial that the state's allegiance to fossil fuel development endangers their health and livelihoods and threatens future generations."

The North Atlantic is heating up... can the South Atlantic be far behind?

"He and other researchers said there are several factors that may be contributing to the off-the-charts warming, which is occurring alongside other climate woes including record-shattering wildfires in Canada, rapidly declining sea ice in Antarctica and unusually warm temperatures in many parts of the world, not including Southern California.

Underlying everything is human-caused climate change, said Daniel Swain, a climate scientist at UCLA.

But atop that are a handful of other potential factors, including the early arrival of El Niño; the recent eruption of the Hunga Tonga volcano; new regulations around sulfur aerosol emissions or even a dearth of Saharan dust.

"The North Atlantic is record-shatteringly warm right now," Swain said during a briefing Monday. "There has never been any day in observed history where the entire North Atlantic has been nearly as warm as it is right now, at any time of year."

Nearly all of the Atlantic basin is experiencing anomalous warmth, including the Irminger Sea southeast of Greenland, the western Mediterranean Sea, and the tropics "all the way from Africa to at least the Caribbean," said Gregory Johnson, an oceanographer at NOAA's Pacific Marine Environmental Laboratory."
