Hot Topic Solar System Earth Climate
Stratosphere Cycles with the Sun
Topic: Climate
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
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
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
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
'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
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
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
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.

Oxygen Chilled the Earth
Topic: Climate
Scientists have determined that the rise of oxygen on Earth may have caused the planet's first ice age. The research team believes that rising oxygen levels could have consumed atmospheric greenhouse gases, ultimately cooling the entire planet and profoundly influencing the evolution of life.

Mussels on Acid
Topic: Climate
By studying how mussels adapt to acidic waters near underwater volcanoes, scientists are gaining a better understanding of how climate change could affect the ecology of Earth's oceans. Increasing carbon dioxide in the Earth's atmosphere is leading to acidic water in the oceans, which could result in dramatic consequences for life as we know it.
