While I am aware that I have political differences with this sewing blogger, I had been prepared to look at our commonalities instead of our differences. I even took her on a tour of the Olmstead District in Old Town Torrance and introduced her to Momen+ fabric.
I'm not going to link to her blog, because that would drive up the reputation ranking of these #fakefacts. I'm just going to share a screen capture so you can see what I am talking about.
Deep breath here. I read her blog because she is an extremely prolific and skilled sewer, knitter and photographer. She is highly competent in her areas of expertise. I read her blog so I can learn and be inspired.
I don't want to hurt her feelings, but I cannot let lies go unchallenged.
My blog is not glossy and professional. I do not sew prolifically. I sew and blog late at night. I take photos with my phone or a compact point and shoot--often with poor lighting. Why should you believe me and not her?
I work as a data specialist at one of the world's premier weather and climate data archives. Prior to this, I earned a BA in Mathematics and a BS in Chemistry. Then I earned a PhD writing models to compare theory with precision physical measurements. The expertise I developed led to a job in an Air Force research lab running weather models and performing weather satellite Cal/Val (calibration and validation.) I have also run climate models, but only at an introductory classroom level. I eventually landed in my current position. I am working in my third national lab.
I could earn much more money using my math, statistics and computer skills to spy on your web behavior to influence you to buy stuff you don't need. Instead, I'm busy trying to preserve the best quality data available for future generations.
I am proud to be part of the global weather and climate enterprise. It takes a huge amount of international cooperation to study our planet for our common safety and good. I would never take part in an international conspiracy to lie to everyone. It's absolutely ludicrous.
The reason that scientists are so alarmed about global warming is because it is a threat to all life on earth. We're all going to fry together unless we work together to change our behavior.
So let's unpack the statements:
I don't believe in global warmingNeil deGrasse Tyson said, "The good thing about science is that it's true whether or not you believe in it." He's right in that the planet is frying whether or not you believe in it. But it's not a good thing.
or climate change or whatever they are calling it these days.Don't blame the scientists. Blame the political appointees in the Bush 43 administration that forbade federal scientists from using the term, "global warming." Our scientific findings and reports were even scrubbed by fresh out of college political science majors with no science expertise whatsoever but fantastic partisan bona fides. But that is another rant.
The Obama administration did not renew that rule and some scientists drifted back to using global warming, while others use climate change. The planet does not warm uniformly, so there are good reasons to use CC when referring to some effects.
To me, it’s all weather, in some ways it’s predictable, in others it’s not.This sows confusion. "Oh, well. We don't know for sure so let's ignore it." No, we cannot ignore it and it is not confusing at all.
Actually, weather and climate are different things to scientists. The simplest definition is "Weather is what you get; climate is what you expect."
Edward N Lorenz wrote a classic explanation.
Weather is on a short time-scale and we are really good at predicting it. In fact, a 10-day forecast today is as accurate as a 3-day forecast was 20 years ago. I've written about Verification Statistics for my work blog. Weather verification is ongoing and published openly on the web. We got nothing to hide.
Climate models are similar and also very different from weather models. They have all the same physical models of how air, water and trace gases behave. But, they also vary in their external forcings (e.g. sun) and boundary conditions. Both types require millions of lines of computer code.
Early weather and climate models were not so good but both experienced continual improvement. Weather models are easier to verify and improve because of their short time-scale. I'm not going to live to see the verification statistics of 2100 climate simulations. I'm going to have to trust that, because climate models verify well with the past, they will preform similarly well in the future.
What has been happening these last few years in California is predictable and following a pattern.I don't know what she means by this. Is she referring to the El Nino/La Nina cycle that reverses every year of two? Or is she referring to the Pacific Decadal Oscillation, a similar warm/cool ocean pattern that occurs on much longer timescales?
When the cool phase of the PDO lines up with La Nina, rainfall plummets in southern California. We expected a few very dry years and we got them. We got a longer dry spell than we were expecting and there is much research about why that occurred. Overall, scientists were less surprised than the media. I don't know if you can blame the scientists or the professional weather communicators who are hired more for ratings rather than scientific accuracy.
This next paragraph took me a long time to unpack.
Simply put, we get rain in the winter, then we get a few years of drought, we always have fires, but at some point, we have massive fires all over the state. The following winter we will have an abundance of rain and snow, then come the mudslides. Maybe back to regular rain for a while and then the cycle repeats.Have you studied rhetorical devices? It's useful to understand how people try to persuade you, even when the facts aren't clear.
Consider the false dilemma. They set up an either or situation. If A is right, then B is wrong. But the fancy talk obscures that there is no real logical connection between A and B.
Yes, California's normally dry summers would qualify as a drought practically anywhere else. That's just our climate. Fire is a perpetual hazard in the American west. Burned areas are prone to mudslides the following winter. All that is true.
Just because weather and seasons are cyclical does not mean that the climate is not changing.
2016 was the hottest year globally in modern history. Higher temperatures cause more water to evaporate both directly and indirectly through evapotranspiration of plants. Even with the same amount of water, high temperatures will create drier and more combustible forests. We are already seeing this. The fire season is starting earlier and ending later. We are experiencing wildfires in January!
Just because it rains in the winter, does not mean that our climate is not changing. No one is saying that climate change = no seasons. In fact, we expect more weather extremes in both precipitation and temperatures. That is exactly what we are experiencing.
The Sierra snowpack is a complex and highly alarming subject that deserves its own post at a later date.
Next, I plan another post about kettle logic and how it is weaponized to confuse people about science.
I haven't sewn anything since early December so I might as well blog about science. #resist
