contribute to it, or worry about it.
The "Middle Age Warming" event was good for people- they were growing grapes in England, and Greenland was settled. One hundred years later the cold
climate returned, the grapes died, and people abandoned the Greenland settlements or froze to death.
Easy choices, and not a lot of humans around on the planet to be impacted or take detailed, science-based notes about what happened. They were more
worried about plague, inquisitions etc.
What has changed since then is the scale and scope human activity that exacerbates the effect. Also, the fact humans have constructed cities, roads,
housing, etc. based on certain temperature/climate/weather assumptions: sea/lake levels, storm intensity/duration/seasonality, availability of food,
average temperature variation.
We harvest fish from the seas based on assumptions about productivity that fluctuate over time. Add industrial-scale human harvesting and the lows get
lower, leading to fishing quotas.
We grow crops based on assumptions about rainfall/pollinators being readily available. As bees disappear and the rainfall declines, farms fail and
drought restrictions are implemented.
We raise livestock believing there will always be plenty of grazing land with available grass/water to feed them. The price of beef has collapsed and
ranchers can't afford to feed their cattle.
We build airports and design airplanes with certain meteorological ranges in mind. The heat in Phoenix results in the airport closing during the
afternoon in the summer months, cancelling flights or diverting them to other airports.
Adjust, adapt, move on. Just don't deny what's happening or argue about what's causing it. Make plans to manage the changes- add rainwater harvesting
to building designs. Rely more on solar/renewables and less on fuels that are more difficult to manage/obtain,
I completely agree that what we are seeing is "natural" and has happened many, many times before. The difference is: what happens now has an impact
on human design on a scale not experienced before, and causes expensive and at times dangerous situations to occur.
So, IMHO, it doesn't matter why this is happening, but it makes sense to plan accordingly to avoid expensive/dangerous situations from harming people
as we go forward. |
