James Hansen, director of the Program on Climate Science, Awareness and Solutions at the Earth Institute and former director of the NASA Goddard Institute for Space Studies, is being honored with the BBVA Foundation Frontiers of Knowledge Award in Climate Change.
Climate change is already affecting New York, and these changes will have profound effects on its ecosystems, plants and animals. What are the implications of these projected changes?
Denying the science of global warming is absurd, but accepting the science of climate change does not require decision-makers to accept the policy prescriptions of climate scientists.
The Earth Institute digs into the past, tracks the present and models the future of climate. We explore the broader issues surrounding climate change, seek ways to apply our knowledge to real solutions, and nurture collaboration among faculty and researchers in the natural sciences, social sciences and humanities, law, public health, engineering, architecture and urban planning.
The Arctic is warming twice as fast as the rest of the planet, and scientists are seeing the effects across ice and ecosystems. Lamont-Doherty Earth Observatory’s Marco Tedesco describes the changes underway.
Declassified spy satellite images are beginning to provide the first consistent look at how glaciers across the Himalayas are changing and what future water supplies might look like for millions of people.
The election of Donald Trump has climate scientists concerned about its implications for U.S. environmental policies and worldwide efforts to curb the effects of climate change. Many fear that climate science under Trump could be strategically undermined in a variety of ways.
A new study documents evidence of a massive release of carbon from Siberian permafrost as temperatures rose at the end of the last ice age.
We do not know enough about our planet and the impact of human technology on its basic systems. It is beyond idiotic to think we can grow our population and consumption this much, this quickly, and have no impact. But it is also foolish to overstate what we know and ask policymakers to invest trillions of dollars on impacts we have not yet seen. Scientists need to be encouraged and funded to present facts, projections and options.
Due to warming climate and increasing human exploitation, far northern forests and the tundra beyond are undergoing rapid changes. In northern Alaska, scientists from Columbia University’s Lamont-Doherty Earth Observatory and other institutions are studying the responses of trees at the very edge of their range.
