This is a brief post on a very big topic and my frustration with current events.
Working in other countries gave me an appreciation what a gigantic and complex system we live in and on and how little we know and what affects one continent will affect another eventually. Can't be American or euro centric here.
Europe has just been through an incredible heatwave that shouldn't happen at all in June (not even in Spain) and especially not for an entire month.
My friend vacations in Croatia every year and told me that two years ago the ocean was cold on top and warm on the bottom and continues the opposite of what it should be doing.
The reason why I'm not fond of ancient or prehistoric geology/history is because we can only guess what truly happened and there is too much opposing research.
The Sahara was an ocean 30 million years ago. A quick search did not reveal what turned an ocean into a desert and hiw long it took.
What were dealing with now is a combination of tectonic plate movement, ocean currents, weather patterns, heliophysics (how the sun influences us) and little to no idea how all these systems interact and are connected.
If we don't know that, we don't know how we can fix it.
This is a simplified map of ocean currents.
These are just ocean currents. The AMOC an Atlantic current has slowed down. How significant that is is unknown.
There is no question that the speed of current climate change is anthropogenic, but cataclysm have happened in the past. The ancient Egyptians are the perfect example. The verdant nile was no more, a successful civilization disappeared. Many theories abound.
This time we are focused too much on Fossil fuels. I don't think thy are the sole reason and the only solution.
What concerns me is Chernobyl. There is an ecosystem again because nature fills a void. The animals aren't thriving they are suffering short lifespans, illness mutations. The fact that green frogs are now black to adapt to radiation means that this has happened before. Not man made radioactivity but radiation has triggered some gene to produce melanin. Amphibians have been around for millions of years. Did they deal with a cloudless sky and radiation from the sun?
There is a reason that genetic contingencies exist on a hostile planet.
Food for thought and science.
