Perspectives for regional earth system modeling

The recent development of regional climate models which can potentially produce long-term (multi-year to multi-decadal) simulations at high spatial resolution (5-50 km), opens a range of possibilities for interactive coupling with ecosystem, hydrology, ocean-sea-ice and chemistry models on the regional scale. Such coupling offers two primary advantages: (1) It is accomplished at scales more con...

The UN International Year of Planet Earth-Background and Perspectives

The “International Year of Planet Earth” (IYPE) is a joint initiative by the International Union of Geological Sciences (IUGS) and UNESCO and runs from 2007 to 2009.

Earth-viewing satellite perspectives on the Chelyabinsk meteor event.

Large meteors (or superbolides [Ceplecha Z, et al. (1999) Meteoroids 1998:37-54]), although rare in recorded history, give sobering testimony to civilization's inherent vulnerability. A not-so-subtle reminder came on the morning of February 15, 2013, when a large meteoroid hurtled into the Earth's atmosphere, forming a superbolide near the city of Chelyabinsnk, Russia, ∼1,500 km east of Moscow,...

Challenges of a Changing Earth: Past Perspectives, Future Concerns

Paleoclimatic research has revealed an astonishing picture of past changes in the earth system. Over the last 2 million years, climate has varied widely from ice ages to warm interglacials. Between these extremes global sea-level varied by up to 130m, alternately exposing and submerging land bridges that provided gateways between continents for the migration of early humans. Ice sheets grew to ...
