Hot Topic Solar System Earth Climate
Ocean Acidifcation, Climate's Step Sister
Topic: Climate
Summary: The Hot Zone recently discussed ocean acidification and what it could mean for the future climate of Earth. Earlier this month expert panels organized by the United Nations discussed ocean acidification and the future of Earth's marine ecosystems.

Prospects of a Geoengineered World
Topic: Climate
Summary: The Hot Zone recently featured a conversation with Dr. Philip Rasch of the Pacific Northwest National Laboratory. Dr. Rasch and his team create mathematical models of what the Earth´s climate might look like in the future.

Stratosphere Cycles with the Sun
Topic: Climate
Summary: Scientists have found that the 11-year solar cycle, the stratosphere and the tropical Pacific Ocean work in sync to generate periodic weather patterns that affect the globe. The findings could be used to predict future climate patterns on Earth.

The Case of the Missing Ice
Topic: Climate
Summary: By modeling ice sheets in Antarctica, scientists have changed the way we think about Earth's transition 34 million years ago from warm 'greenhouse' to the current, cool 'icehouse'. The new study has important implications for how we understand climate change and its affects on the biosphere.

Ice Ages Follow the Sun
Topic: Climate
Summary: Scientists have shed new light on the processes behind the Ice Ages experienced by Earth over the past 2.5 million years. Research indicates that they are ultimately linked to shifts in solar radiation caused by changes in the Earth's rotation and axis.

Ancient Booms and Busts
Topic: Climate
Summary: Research suggests that a period of global warming strongly influenced plants and animals some 53 million to 47 million years ago during the Eocene epoch. The study could help scientists understand the effects that climate change will have in Earth's future.

Topic: Climate
Summary: 'Geoengineering' refers to human-made changes to the Earth's land, seas or atmosphere that are intended to help slow climate change. However, some scientists are worried that geoengineering techniques may cause more harm than good.

Plants Limit Ice Ages
Topic: Climate
Summary: During the last ice age, glaciers advanced over much of the Earth's surface. Scientists have long wondered why the planet didn't freeze over entirely. New research shows that Earth may have been saved from a runaway 'icehouse' by plants.

Linking Climate and Habitability
Topic: Climate
Summary: The change in Earth´s climate may help scientists better understand planetary habitability in general. Scientists are now learning how small shifts in climate can have dramatic consequences for the planet´s environment and the life that depends on it.

A 30-Million-Year Blip
Topic: Climate
Summary: New research shows that a 'brief' ice age in Earth's past actually lasted for 30 million years. During the ice age, global warming was curbed by the natural burial of organic carbon underground. The study is helping scientists understand the historical connections between the biosphere and the environment of Earth.
