Asteroid Spotted Just Two Hours Before Impacting Earth

From CNet.com:
"Two hours. That's about how much time elapsed between the discovery of asteroid 2022 EB5 and when it reached Earth's atmosphere. The asteroid is only the fifth one to have been detected before impact. "

Whew!

Close Call. Actually it impacted but was small enough that the damage was minimal!

And they have introduced a new unit of measure for the size and mass of asteroids - the Giraffe.

This one was half a giraffe.

I read about this, really gives you a bad feeling about what if it were a big one.
I’ve learned a lot since I knew it all.

Hi Johnny,

Oh, I wouldn't waste time worrying about extreme low probability "what-if?" scenarios like this.

I worked for nearly 40 years in climate change research. With 70m of sea level rise stored up in the polar caps that are both simultaneously experiencing temperature 40C (70F) above average at present, the recent collapse of the city sized Conger Ice Shelf, and higher frequencies of extreme weather, not to mention threats of global conflicts, there are many more imminent threats of either high probability or total certainty to concern yourself with. Major polar melts were thought to be hundreds of years off but those projections never factored in 40C temperature rises.

We're going to lurch between climatic extremes like polar vortex events, tornados and hurricanes, flooding rains to periods of droughts and raging forest fires with only brief periods of "normal" in between. Normal will no longer be normal.

The attached animation shows how, under a full polar melt, the entire state of Florida and most of the eastern USA seaboard would go under, the great lakes would merge into one large inland sea and even Texas will loose a lot of land. From the resolution of this map, I can't tell if Weatherford, TX will become seaside real estate or under water.

There, do you feel better now. :lol: :lol: :lol:

Joe

Actually, I am feeling pretty good about them seeing an asteroid that small at all. If they can see one that small at all, it means to me that whomever is doing the looking is getting pretty good at it. "We" just need to keep pressing forward and get better and better at it. :)
