I made a post in another thread, stating that people who denied human-caused climate change were either willfully ignorant, or paid to hold that opinion.
Some people took offense.
Since not many people paid to troll forums like this get through the approval process, it's worth giving most the benefit of the doubt.
So, if you do take offense, I have a question.
If it was true, would you want to know?
About a year and a half ago, there was some question as to whether the current rate of oceanic acidification
was matched anywhere in the past 300 million years
.There is no more doubt about this.
I would highly suggest reading the articles regardless of viewpoint.
The impact of what humanity is doing is enormous. 40% of Oceanic phytoplankton has died off in the past half-century.
This is not some recoverable cyclical change - species of plankton are actually being wiped out
Some skepticism comes from the form of "How could humans possibly have this much of an impact?"
Geology does give us a sort of measuring stick, in the form of igneous provinces
. The most famous of these are the Siberian Traps
, responsible for the largest mass extinction in the fossil record. These 'events' are in fact comparable
to human activity - the total amount of fossil fuels we've burned + will probably burn is of a similar total magnitude, in terms of what gets released into the atmosphere.
Similar, but for one point: Humans are releasing carbon and other pollutants at least ten times faster than any flood basalt province we can analyze. There is no parallel, no point you can cherry-pick from history to say "but THIS!"
The impact of human emissions is a singularly unique event in world history, and its effects are reflecting this. Insurance companies are not betting on denial, either.
Nor are most governments.
Go look up more about what is going on with Earth's oceans, if you can stomach it. They are a catastrophe in the making.
You cannot spend any meaningful length of time studying the Earth's oceans, and what is happening to them, without coming to a fairly solid conclusion.
Which generally resembles "How thoroughly have we fucked ourselves?"
Not as much as some apocalyptic nutjobs will proclaim, no. The cost of ignoring it goes up with each election, however, and it will be paid one way or another.
