Not misleading
I interpreted the title in the vein of "We finally have a good guess!" They are researchers after all.
As a Californian like you I am particularly interested in enso as well and love the content here as I continue to educate myself.
While the drought is more likely to continue this is not certain. If you look at the other blog posts there is some good historical data. So I hope for rain anyway. (If I'm wrong please correct me as I'm just an enthusiast)
Additionally there are global implications and while visiting a climate blog, albeit the posts on here are from an American perspective, it's something I would think a lot of people have in mind while thinking climate.
La Nina means different things to everyone. So why interpret global implications from such a small scope and then think the title applies to your specific lens?
I'm sure like me you are personally invested and have strong feelings about the implications, but something to keep in mind for when you come back!
