How does the Medieval Warm Period compare to current global temperatures?
The Medieval Warm Period was not a global phenomenon. Warmer conditions were concentrated in certain regions. Some regions were even colder than during the Little Ice Age. To claim the Medieval Warm Period was warmer than today is to narrowly focus on a few regions that showed unusual warmth. However, when we look at the broader picture, we see that the Medieval Warm Period was a regional phenomenon with other regions showing strong cooling. What is more, and as can be seen in Figure 4, globally, temperatures during the Medieval Period were less than today.
Interesting isnt it that phrase narrowly focus, aka the horse pic above..... its a dynamic we are seeing played out over and over again.
Cherry pick a subset of the total data and debunk that, ignore the larger problem. The totality of our dilema
What cant be denied, and is no doubt the reason why attempts to point it out are greeted with "start a new thread", "this is about climate change". Is that our species is changing the biosphere in many many ways, none of them good.
Since it cant be denied it must be deflected, but thats sheer folly. Playing the fiddle while rome burns
But not just heating up. That's only part of the story. An updated review of Planetary Boundaries, a survey of nine basic systems critical to life on Earth as we know it, finds that human activity has pushed past the boundary of what's safe and stable in four of those categories; climate change, loss of biosphere integrity (things like genetic diversity because of species loss), land-system change (soil and forestation loss, etc.) and altered biogeochemical cycles (how the biosphere uses and replaces the critical elements of phosphorus and nitrogen).
To make it clear, this is bad news. As the authors of the study put it
Right now the global temperature records are making all the news. But climate change is just one symptom of the larger problem that makes very little news but which lies at the heart of why we, and all current Life on Earth, face an unavoidable crash.
You cant restrict this debate to one symptom, to a part of the story.
Thats like having a car engine that wont start and saying well the sparkplugs check out OK.
Maybe they do, but that doesnt solve the problem does it ?
You must isolate the root cause, even if , especially if ,its manifesting in multiple problems/symptoms.
Your car is rolling downhill at breakneck speed heading for the jetty and bay below, your response here is akin to saying, well the cigarette lighter is working no problems. why the fear mongering ? its works fine
