A poster from the 2012 Holiday Lectures on Science, Changing Planet: Past, Present, Future. It details the importance of foraminifera, known as "forams" for short, in discovering significant changes in Earth's past.
A poster from the 2012 Holiday Lectures on Science, Changing Planet: Past, Present, Future. It illustrates how the Earth has evolved over the past 4.6 billion years, and highlights how that evolution influences biological evolution.
Has Earth changed over deep time? How did Earth shape life and life shape Earth? What does Earth's climate in the distant past tell us about the future?
Microbes have been the dominant life form throughout Earth's history. Eukaryotes and animals evolved only after microbes evolved oxygen-generating photosynthesis.
The theory of plate tectonics took many decades to become accepted. The process by which it was finally accepted provides a fascinating glimpse into how scientists build new scientific consensus.
Earth has been both cooler and warmer in the past, but the change is usually gradual. The current rate of carbon dioxide increase is unprecedented in human history, and solutions to mitigate its effect on global warming are challenging to implement.
Scientific evidence for global climate change is overwhelming, yet the American public remains skeptical. History provides insights into how a Cold War-era think tank became an influential source of anti-regulation sentiment.
A discussion on climate change with the students attending the 2012 Holiday Lectures on Science.
Continents rose in elevation after ice sheets from the last ice age retreated. This suggested that the underlying mantle is pliable.
The concept that continents float on a pliable mantle is an important element of the theory of continental drift.
A grassroots effort by winter sports professionals aims to convince the government to take action on climate change.
Dr. Knoll describes the path to becoming a geologist, and explains the importance of collaboration in scientific research.
Dr. Oreskes explains her switch from research science to science history, and what led her to write Merchants of Doubt...
Dr. Schrag recalls his parallel interests in earth science and political science and how the two have merged over the years.
A graduate student in the Knoll lab, Ms. Creveling explains how she selects field sites, and what sparked her interest in geology.
A graduate student in the Schrag lab, Mr. Laakso uses computer modeling of Earth's atmosphere to help predict changes to come.
A postdoc in the Schrag lab, Dr. Shoemaker works on the greenhouse gas methane, which has surprising natural and man-made sources.
Sunlight that warms Earth is re-emitted as infrared radiation, which is absorbed by greenhouse gases and causes further warming.
CO2 emitted by volcanoes into the atmosphere is removed by a...
