Arctic warming causes Siberian cooling

The Arctic is warming faster than anywhere else on Earth, and fall sea-ice extents have been trending downward for decades. But while the region is heating up, that northerly warming seems to be having the opposite effect on some midlatitude locations: Parts of Siberia near the Ural Mountains, for example, have had anomalously cold winters in recent decades.

The impact at El'gygytgyn crater

Moment of impact: As the asteroid hits the ground with a velocity of several tens of kilometers per second, a shock wave is generated that penetrates radially into the ground and compresses the rocks.

Early results

Although our final results won’t begin to be published until early next year, our team met in May to review all the data we had collected so far.

We had drilled several types of cores. Our initial pilot cores, taken in 1998 and 2003, provided proof of concept, demonstrating the importance of these cores as a climate record, as they contain climate data that extend back in time 300,000 years — roughly three times longer back in time than the oldest portions of the Greenland ice core records.

The thrill to drill in the chill

Nearly 3.6 million years ago, a large asteroid slammed into Earth in what is today northeastern Russia. Within minutes, the impact formed an 18-kilometer-wide hole in the ground that then filled with water.

Travels in Geology: Exploring Lake Baikal, the Sacred Sea

Deepest. Oldest. Most biologically diverse. Siberia’s superlative-laden Lake Baikal is one of the planet’s great geological treasures. Located 4,200 kilometers east of Moscow and 2,100 kilometers west of Vladivostok, the lake known locally as the Sacred Sea is like no other.
