  • '100-year' floods will happen every one to 30 years, according to new coastal flood prediction maps

    A 100-year flood is supposed to be just that: a flood that occurs once every 100 years, or a flood that has a 1% chance of happening every year.

    But Princeton researchers have developed new maps that predict coastal flooding for every county on the Eastern and Gulf Coasts and find 100-year floods could become annual occurrences in New England; and happen every one to 30 years along the southeast Atlantic and Gulf of Mexico shorelines.

  • When will we observe significant changes in the ocean due to climate change? New study offers road map

    Sea temperature and ocean acidification have climbed during the last three decades to levels beyond what is expected due to natural variation alone, a new study led by Princeton researchers finds. Meanwhile other impacts from climate change, such as changes in the activity of ocean microbes that regulate the Earth’s carbon and oxygen cycles, will take several more decades to a century to appear. The report was published Aug. 19 online in the journal Nature Climate Change.

  • Offshore oil and gas rigs leak more greenhouse gas than expected

    A survey of offshore installations extracting oil and natural gas in the North Sea revealed far more leakage of methane, a powerful greenhouse gas, than currently estimated by the British government, according to a research team led by scientists from Princeton University.

  • A small number of leaky natural gas wells produce large emissions of greenhouse gases

    Wells that extract natural gas from underground often leak large amounts of methane, a powerful greenhouse gas, into the air. A team of Princeton University researchers has found that, in one of the biggest gas-producing regions, most of these emissions come from a tiny subset of the wells, a finding with major implications for how to control the problem. 

  • Fewer fish may reach breeding age as climate change skews timing of reproduction, food availability

    Climate change may be depriving juvenile fish of their most crucial early food source by throwing off the synchronization of when microscopic plants known as phytoplankton bloom and when fish hatch, according to Princeton University researchers. The long-term effect on fish reproductivity could mean fewer fish available for human consumption. 

  • More farmers, more problems: How smallholder agriculture is threatening the Western Amazon

    Monday, Jul 15, 2019
    by B. Rose Kelly, Woodrow Wilson School of Public and International Affairs

    A verdant, nearly roadless place, the Western Amazon in South America may be the most biologically diverse place in the world. There, many people live in near isolation, with goods coming in either by river or air. Turning to crops for profit or sustenance, farmers operate small family plots to make a living.

    Unfortunately, these farmers and their smallholder agriculture operations pose serious threats to biodiversity in northeastern Peru, according to a team of researchers led by Princeton University.

  • Sea slugs use algae's bacterial ‘weapons factory’ in three-way symbiotic relationship

    Thursday, Jun 27, 2019
    by Catherine Zandonella, Office of the Dean for Research

    Delicate yet voracious, the sea slug Elysia rufescens grazes cow-like on bright green tufts of algae, rooting around to find the choicest bits.

    But this inch-long marine mollusk gains not only a tasty meal — it also slurps up the algae's defensive chemicals, which the slug can then deploy against its own predators.

  • Redding explores the brightening future of solar power in the Philippines

    Wednesday, Jun 26, 2019
    by Morgan Kelly, Princeton Environmental Institute

    As a tropical nation spread across more than 7,600 islands, the Philippines seems like the ideal location to implement localized solar power for the 16 million Filipinos lacking reliable access to electricity. But as Princeton senior Erin Redding discovered, providing lasting energy solutions requires much more than a willing populace, low-cost technology and ample sunshine.

  • Rapid Switch project to assess practicality and pace of global climate strategies

    Monday, Jun 24, 2019
    by Molly Seltzer, Andlinger Center for Energy and the Environment

    Princeton University convened an international research team June 11-13 to begin a five-year effort to frame a realistic global response to climate change that accounts for massive economic development in countries, including India and China.

  • Ramaswami, researcher of urban sustainability, appointed inaugural director of M.S. Chadha Center for Global India

    Anu Ramaswami, an interdisciplinary environmental engineer who is recognized as a pioneer and leader on the topic of sustainable urban systems, has been named professor of India studies, civil and environmental engineering, and the Princeton Environmental Institute, and the inaugural director of the M.S. Chadha Center for Global India. She will assume her new duties at Princeton on Aug. 1.
