THOUGHT EXPERIMENT: Some 70% of people, depends how you ask, accept the global emergency. Climate system destabilisation is one aspect, declining biodiversity and increasing pollution is another. I ask: what would actually *break* if humanity responded decisively? 1/

Comparing two environmental regulation

Preventing emissions vs improving water quality,

Which one better?

https://t.co/zLrVNWIPXm

What is the Difference?
We certainly often hear the term better to prevent than cure. Of course, we all agree on that. But what about improving quality, is that better than preventing?

A researcher named Dan Pan tries to compare 2 different regulations on environmental impacts.

One of the regulations is based on environmental quality limits. the other is based on the market, but we will call it improving water quality because it gives reward and punishment on environmental performance.

Preventing Emissions:

• Restrictions or closings of companies that violate environmental quality standards

• Restricted areas must protect their water

• Implementing comprehensive water conservation

• Strengthens water recovery and protection

Improving water quality

Give awards to mayors whose evaluation scores are good, and adequate, whose evaluations are bad. There are several parameters defined in determining water quality such as: COD intensity, water quality, and industrial wastewater standards

Thread on very strong inbound CA storm. A cold & clear morning will quickly give way to increasing clouds, NorCal valley rain & snow down to 1,500-2,000 ft (locally lower) later this PM. Current satellite imagery shows this strengthening system off the coast. (1/10) #CAwx

Tonight, a rapidly intensifying cold front will sweep across NorCal. This front will be unusually well defined, for a CA winter storm, and will replace an already cold airmass with...another cold airmass! (2/10) #CAwx

The cold frontal passage is expected to be quite dramatic across NorCal in the overnight hours. A convective "narrow cold frontal rainband" (NCFR) will likely develop, which could bring a period of torrential rain or snow to many areas, as well as possible lightning. (3/10) #CAwx

Extremely heavy precipitation is possible for a 30-60+ minute period when this NCFR feature moves ashore. Over an inch of rain could fall per hour in some spots. This portion of the event poses a high threat of debris flows in/near recently burned areas. (4/10) #CAwx

In addition to torrential rainfall, the cold front/NCFR will be accompanied by very strong wind gusts across much of NorCal. In fact, high-res models are suggesting potential for gusts of 60-70 mph even in lower elevation places. Widespread power outages possible. (5/10) #CAwx

It's #FigureFriday, so let's chat about my favorite subject: color palettes 🎨 for climate science visualization! (1/12)

First, why is it important? Put simply: a beautiful figure can communicate your results more effectively than text. It can make a figure more understandable to a public audience. So it is worth it to put care into your figure design. (2/12)

First, if you're plotting up climate model data, especially anomalies, I highly recommend Cynthia Brewer's palettes on ColorBrewer. BrBG is my go-to for precip anomalies, and RdBu is a natural for temperature. (3/12)

The sequential palettes are also great if you've got data going in one direction. Here's the Brewer "blues" at work for a figure showing LGM T change. (4/12)

But what about line graphs? If you are paleoclimatologist like me, you are probably plotting a bunch of squiggly lines. For this, I suggest designing a palette for your *entire paper* ahead on time, and then plot stuff in this palette in every figure. (5/12)

There's a huge gap between what climate scientists are willing to say privately and what we're willing to say publicly, in terms of how dire a situation we're in. Colleagues, integrity demands we close this gap.
