For three Mars summers in a row, Mars' southern polar cap has shrunk from the previous year's size; this suggests that at least some parts of Mars are experiencing warming. .
This mat be explained by a 2004 study at the Max Planck Institute for Solar System Research in Germany, which concluded that "the Sun is burning more brightly than at any time during the past 1,000 years" and attributed recent global climate change on earth to the combined effect of greenhouse gases and increase in solar activity.
The present level of solar activity is historically high. Solanki et al. (2004) suggest that solar activity for the last 60 to 70 years may be at its highest level in 8,000 years; Muscheler et al. disagree, suggesting that other comparably high levels of activity have occurred several times in the last few thousand years. Solanki concluded based on their analysis that there is a 92% probability that solar activity will decrease over the next 50 years.
