I really don't understand why something that is presumed preventable with little investment is allowed to continue happening. What's worse is the water shortage is what I don't understand. It's a state literally bordering the ocean.

That graph is impressive, and really shocking how much land these fires are just taking.

> We download the reprojected data from UW SSEC's RealEarth program

I really wish GOES's official images would provide the high resolution imagery directly. We shouldn't have to go through RealEarth to get it. However I've noticed that only RealEarth has the highest resolution images.

Thanks for sharing. Do you work with the folks at Watch Duty?

Nice, thanks but did you know about NASA FIRMS?

Wildfires in California date back millions of years and are a natural part of the region's ecology. The difference in recent centuries has been dense human habitation. I think your statement about presumed prevention is inaccurate or misleading.

Who's presuming it's preventable? What little investment do you suggest California make?

Probably slow controlled burns would be helpful in reducing potential fuel, but who's going to perform controlled burns over the entirety of all the hills surrounding LA ?

Another difference is a steady increase in the world temperature due to climate change.

No, looks like they're doing a way better job! Thanks for sharing. I was only aware of the GOES sats. Seems like VIIRS is more intended to do this kind of monitoring.
