Global warming on Mars? Apparently so.
A Russian astronomer, Habibullo Abdussamatov, blames fluctuations in solar radiation. He thinks that's why Earth got warmer, too.
Other scientists dismiss his views. They say Earth and Mars are warming up for separate reasons.
They say that warming here is due
To human production of CO2.
On Mars, they say the rotational fact is
That warming is due to a wobbly axis.
Perhaps this theory is the cleanest,
But I'd like to see some stats for Venus.
