I'm talking about the drought in 2008 ( as compared to 2007 )


sort by: page size:

Last year wasn't exceptional in regards to drought on average[1]. Obviously some areas were more dry and some were less dry.

To be fair most of that decade has been a state-declared drought (2012-2016) :) and I believe the interceding years were also usually low in terms of precipitation even though they didn't meet the formal definition of a drought.

None of that detracts from this of course.


Current drought is ridiculously bad, but is exacerbated by the ridiculously wet period that preceded it.

Do you mean that drought is more common than what we have been experiencing?

A drought isn't climate change. The annual weather is a chaotic system, and a drought for a year or two (or even 10) is normal. Climate change is much longer term.

Big droughts have come and gone over the years. Here’s a nice historical data explorer: https://www.drought.gov/historical-information?dataset=0&sel...

Climate change changed the odds of such a drought from 1 in 100,000 to 1 in 25.

It's easier to imagine the drought conditions of recent years/decades repeating.

As someone who has lost track of drought info. Is this still a net-positive for the region?

There have been droughts in the past. But a drought in the past would be no proof that climate change is not real.

More interesting to me are the change maps that show if drought is getting better or worse over some period

12 months seems to be the max change range and it only goes back to July 2004, but cool to see!

I did say drought twice rather than heatwave. It seems 1976 is still drier than 2022. At the moment that is.

No - they're saying that what we call "drought" isn't actually drought, in historical context. It just seems that way if we're looking at too short of a timescale.

The edit window on the parent comment has expired, but here's some direct data on droughts:

So I think it's fair to say that while the evidence may be debatable, it is not "scant".


if the worst drought in 1/2 a century occurred in 2012, then why is that a trend upward if a worse one was in 1962?

Uhm, okay, you have convinced me that droughts aren't a new phenomenon.

The claim however was that they become more frequent and severe. Not every drought is the same. From your link:

> the 2012–15 period was the driest in at least 1200 years

Also, according to your link, about there was a drought in 12 of the last 20 years, with only one or two years in between droughts, where they previously usually were spaced by around a decade or more.

The data listed there really doesn't seem to contradict the article's claim about more frequent droughts in the future.


This section of the article answers that:

> Williams was part of a team that published a similar study in 2020. At the time, they found the drought since 2000 was the second-worst after the late 1500s megadrought. With widespread heat and dryness over the past two years, the current drought has passed that extreme mark.

So when they first looked, it was the year 2020 and they looked at the period between year 2000 and 2020. And now they are looking at that plus the additional 2 years that has passed since last time they looked.


You are ignoring an important piece of evidence: I've told you that I'm on a very slow internet connection. Now, I could be lying about that (I'm not sure how I could prove it to you) but if it is in fact true then that would explain my failure to come up with additional evidence. I have been trying to access drought data directly but it all seems to be hiding behind complex visualizations which I cannot currently access.

However, I think it is telling that so far not a single participant in this conversation has (AFAICT) even tried to get to the actual drought data to see if there is anything there. Somewhere out there, one of you has to be on a high-bandwidth connection, so you could go get the data and settle this, where I currently cannot. That would seem to me to be a more constructive (to say nothing of definitive) way to address this than to accuse me of confirmation bias and rationalizing.

[UPDATE:] Found some drought data:
