Can we control the temperature of Earth?

[macdoc]

Yep par for the course- much chatter from said poster - little or no substance or support.

I always get that wrong - being in the i business after all

I'm beginning to think that there is going to be more and more focus on geo-engineering as consequences like those in Russia currently start to unfold. Hell, 5,000 dead and no relief in sight.

Some small silver lining

Russian fires prompt Kremlin to abruptly embrace climate change

Amid what is called the worst Russian fires in history, President Dmitry Medvedev – who recently dismissed concerns over emissions – embraces the need to address climate change.

Thankfully a La Nina is unfolding

which will help some regions impacted by the additional asymmetrical warmth - not sure of the impact on the Arctic /subArctic tho...it's starting to have a momentum all on it's own -the next Arctic report card for 2010 should prove very interesting.

Maybe the title of the thread should be changed from
can we control the temperature of the earth
to
we have to control the temperature of the earth

You are confusing albedo for the earth ( circa 30% ) with reflectivity of the atmosphere


The atmosphere reflects about 6%

If you are going to nitpick then
a) make sure you are correct
b) support it.

iomiller's casual comment

stands...

Your own picture supports it, only 51% is absorbed by the surface, the other 49% interacts with the atmosphere (almost exactly what I said, trying adding). That's hardly "transparent". The comment is rejected as yet another case of overstating the facts unnecessarily to make a point.

Now"space", space is largely transparent to sunlight. I'll let you figure out why.
