Both. The popular press tends to overhype things but AGW is a serious concern.
Collapse of agricultural infrastructure. Economic destabilization. Billions of dollars lost on coastal disasters which may get more and more common. The shutdown of the AMOC in the North Atlantic and attendant economic collapse of most of our major trading partners' economies in western Europe.
That enough?
Decarbonization. Changes in land usage.
This is hyperbole ... matters greatly exaggerated beyond reality ... worse than overhype ...
Where has the "agricultural infrastructure" collapsed because of the previous 1ºC? ... and what is this infrastructure you speak of ... I've lived on a number of different farms, both big commercial operations and small "off-grid" homesteads ... the only difference to agriculture is longer growing seasons and less risk of frost damage ... some extra rainfall ...
In fact, we're feeding twice as many people today than we did 40 years ago ... even with the 1ºC temperature increase ... it might take an addition 2ºC over the next 100 years to feed the extra 24 billion people we'll have at this rate population increase ...
Will we have to grow wild rice in Manitoba instead of Minnesota next century ... who cares? ... The Ukraine feeds the world, climate is the least of their concerns right now ...
Coastal disasters ... hypercanes? ... go ahead, explain ... satellite altimeters only give us 2 foot sea level by year 2100 {
Cite} ... that doesn't even overtop the docks ... and that's if the docks last 80 years (hint: they don't) ... and I'm fine with just "billions of dollars", Deep Water Horizon cost BP $65 billion {
Cite} ... sounds like climate change costs are cheaper than the remediation ...
[sigh] ... go long ... "104% of ALL scientists world-wide say this is gonna cost us hundreds of
trillions of dollars" ... better odds of hyperinflation than climate change ...
AMOC runs at 0.01 m/s ... Gulf Stream at 2 m/s ... which is transporting more energy gram-for-gram? ... duh ...
=====
Do you have any demonstration of any of these catastrophes? ... we know from the ice core data that temperatures were closer to 4ºC higher at the beginning of the Holocene ... coincident to the Agricultural Revolution ... if any of this is to happen, then it would have happened before ... evidence is very thin ...
Changes in land usage.
A lot of good reasons for this that have nothing to do with climate change ... why do you persist when we'll need clean water long before the climate bites us ... and we need fresh air ... healthy soils ... honest government ...
... and you didn't say "ditch your A/C" ...
