Simultaneous warming on Earth and Mars suggests that our planet’s recent climate changes have a natural—and not a human-induced—cause, according to one scientist’s controversial theory.
Earth is currently experiencing rapid warming, which the vast majority of climate scientists says is due to humans pumping huge amounts of greenhouse gases into the atmosphere. Mars, too, appears to be enjoying more mild and balmy temperatures.
In 2005 data from NASA’s Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide “ice caps” near Mars’s south pole had been diminishing for three summers in a row. Habibullo Abdussamatov, head of space research at St. Petersburg’s Pulkovo Astronomical Observatory in Russia, says the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun.
“The long-term increase in solar irradiance is heating both Earth and Mars,” he said.

Odd materials recently found on Mars have planetary scientists scratching their heads.
That’s because the materials were spotted at the red planet’s equator—but they appear to contain a large amount of water like that previously seen only at the Martian poles. The finding is based on new high-resolution radar data from the Martian subsurface, which show similarities between the properties of deposits on a hilly equatorial formation called Medusae Fossae and the sediments at the ice-rich poles.

The planet Mars may well have a liquid center, scientists say.
That’s a surprise because Earth’s core, which contains similar elements as Mars, has a solid, metal interior surrounded by a layer of molten metal. The discovery was made by a team of European scientists using a device called a high-pressure anvil, which is capable of producing pressures of up to 6 million pounds per square inch (40 Gigapascals).
In experiments, the authors squeezed together high-temperature mixtures of iron, nickel, and sulfur to replicate conditions found on Mars. The researchers were able to determine that the Martian core is still mostly, if not entirely, liquid.
