According to what measures?
Sea level rise? The rate of increase hasn't changed. Actually it was highest during Lincoln's presidency.
Droughts? Actually less severe and less frequent than 100 years ago.
Severe weather? Wild fires? Also, pretty much unchanged or slightly decreased.
Global temperatures? Sure, seem to be increasing moderately, but there's a ton of complication there. And we don't really know what the impact will be.
I think it's better to stop handwringing over pessimistic alarmist models and to focus on solving real, concrete, addressable ecological problems.
- russelg 4y agoIn Australia, we've experienced all of the above within the last couple years. Worst droughts in 20+ years, biggest bushfire season ever, and now record breaking flooding.
- newrotik 4y agoThis is not correct and proves the point made in the parent's comment. Australia had much more severe bush fires in the 70s [0]. Note that many Australian plants are have evolved to adapt to bush fires, which means they must have been a staple of Australian ecology for many millions of years.

- claytongulick 4y agoIt's pretty strange how all of those metrics start at 1960, no? When you expand the window, the picture changes. Droughts and heat waves in the 1800s and 1930s were devastating killers, and some of the most severe in recorded history.
- xpe 4y ago>> https://www.epa.gov/climate-indicators https://www.epa.gov/climate-indicators > It's pretty strange how all of those metrics start at 1960, no? No, "all of those metrics" on the many pages linked from the EPA page do not start at 1960. Stop making false statements. Doing so hurts your credibility and wastes our time. Try slowing down and reminding yourself of your preconceived biases. Double check what you are seeing. Look for things that don't confirm what you already believe.
- claytongulick 4y agoA bunch of them do. Heat waves, river floods, etc... For the heat wave chart, the stated reason for this is that it's the date where most urban areas started keeping careful records. They also, as a footnote[1] include an image going back much farther [2] which completely changes the picture and analysis. However the text description is all about the increase since 1960, only barely mentioning that it was much worse in the 1930s. How is it possible to look at this and not question it? Making false statements? Slowing down and reminding myself? I've spent countless hours looking at original noaa data related to climate change. I've seen a very clear distortion of data in reporting. > Double check what you are seeing. Look for things that don't confirm what you already believe. That's great advice, maybe we should both take it? [3] [4] I don't need to go through every single measure here, it's pretty easy to discover for yourself if you take a real look at the data. The severity and frequency of things like droughts, severe weather, heat waves are flat, if not in decline when you look across a broader window. Sea level rise is pretty linear for as long as it's been measured [5] NOAA data is pretty clear on this. Arctic sea ice? It has a well known oscillation that generally runs close to 180 degrees out of phase with antarctic sea ice. Again, super easy to learn about if you dig in. Did you know that Arctic sea ice actually increased from 1979 to 2015? [6] Also, measuring sea ice is notoriously difficult and error prone, and satellite data doesn't do a very good job of it. Also easy to learn about. My overall point, which for some strange reason gathers a ton of open hostility, is that we're much better off focusing on concrete ecological issues that can be solved today (not draining aquifers, better agriculture practices, elimination of weird farm bill subsidies to harmful crops, etc...). It's amazing how just pointing that out garners the sort of personal attacks that you leveled at me. Slowing down sounds like good advice!

- xpe 4y agoI'll hear you out, if you cite your sources... > I think it's better to stop handwringing over pessimistic alarmist models ... Which climate models are pessimistic in your view? Which models are alarmist? Please define alarmist as you are using it. What exactly are you measuring when you say "alarmist"? Is there a threshold? Let's get some common footing. Here's a thought experiment and question: Let's say Organization X finds in 90% of model runs, the global climate is disrupted to the point that the USA will face between $400B and $800B of additional costs starting in 2040 and increasing somewhere around 1% to 3% per year. * Is summarizing this finding alarmist? Of course not -- it is only describing a model's prediction. * Is the model alarmist? What would make it alarmist? If the assumptions are unrealistic? But all models are imperfect. So how unrealistic must they be? On the flip side, What models do you recommend? Please share how your favorite models are funded. > ... and to focus on solving real, concrete, addressable ecological problems. According to your definitions of "real", "concrete", and "addressable". Do you think NASA's writing on climate change does not reflect reality? That is is not concrete? That the problems are not addressable? So is NASA alarmist w.r.t. climate change? What about the reinsurance industry? Let's take Swiss Re. Are they alarmist? Please point us to some solid writing (such as a credible report) that summarizes your views. Two final questions: have you studied economics? built predictive models? I'd like to get a sense of good ways to have this discussion. Perhaps we can cut through a bunch of preliminaries and cut to the chase. Do you agree that the following framing is a useful way to think about our response to climate change? Technological constraints define what levers can be pulled and at what cost, in the short-run at least. Political decisions drive how governments spend money. Economic factors constrain financial and monetary options. Over the medium-term, investments in science and technology tend to increase expand the option space.
