Oof. An extra 0.2W/m^2 doesn't sound like a lot if you don't know what these numbers look like, but if you consider that the *total amount of energy* hitting the top of the atmosphere from the sun is only about 1,360W/m^2, just this heat source is equivalent to about an extra seventieth of a percent of the total solar input being retained.

Most of the original input doesn't reach the ground anyway. If you take it as a percentage of the amount that reaches the ground (342W/m^2) it's about a seventeenth of one percent.

That's... um... quite a lot of extra heat.
