The past climate doesn't relate to the present?
That's a pretty bold as well as foolish, unscientific comment.
How will we ever know how polar bears sutvived and the Greenland ice cap didn't melt away when it was 2° warmer for a couple thoudand years in our recent past.
Do you not believe it has been warmer and we just climbed out of the coolest period since the beginning of the interglacial we are in?
Why was it the coolest period in the past 10Ka?

No it is not. Relevancy depends how far back you go. Deserts and forests as a percentage of coverage, continent placement and land mass proximity to equator, ice caps for reflection etc all factor in along with thousands of other things that make today different from yesteryear. We can only use the data as a rough guide. Again why I don't put a lot of stock into climate models.
The Earth was once covered in a three km thick blanket of ice for millions of years. Lots of volcanoes spewed enough greenhouse gas to break the freeze and warm the planet. The planet also had a concentration of 7000ppm 500 million years ago but then if you got in a time machine both you and the potted plant you brought with you would die pretty quickly.
The planet has been through a number of freeze thaw cycles. In the past 10K years since human civilization began we've gone from 180 to 400 ppm with almost all of that happening since the industrial revolution. The current 400ppm is the highest it has been for sure in 800K years and possibly as much as 20 million. We are going to hit 500 ppm or more this century which is a level not seen since the dinosaurs.
CO2 is a potent greenhouse gas. The climate of the planet is being affected by this gas along with the rivers, lake and oceans which are absorbing the CO2 and changing their PH levels (acidification).
We've turned up the thermostat, the furnace has kicked in now it's just a waiting game until we heat the place up. There is zero evidence either historical or from the lab to think there will be any other result and I challenge you to produce anything contrary from a single credited agency or university.
Tell me farmer Petros.........is the growing season in your neck of the woods the same as previous generations?
Are we placing too much significance in a short climatic era? Even a 100 years in the history of climate is a mere flash!
At issue is no time in known history have the concentrations GHG accumulated this fast. 100 ppm increases used to take 100s of thousands of years not a single century. There is nothing remotely like it in the record. That's a principle reason those who eat live love sleep and breathe this stuff are so concerned. This is all uncharted territory.
Climate change called 'medical emergency
The threat to human health from climate change is so great that it could undermine the last 50 years of gains in development and global health, experts warned on Tuesday.
Extreme weather events such as floods and heat waves bring rising risks of infectious diseases, poor nutrition and stress, the specialists said, while polluted cities where people work long hours and have no time or space to walk, cycle or relax are bad for the heart as well as respiratory and mental health.

I haven't been this scared since 2013 when the North pole melted and became ice-free.
That's never happened before.
And the Earth has not gotten warmer in over 18 years.
