Climate Change

I would like to bring to the attention of our community the following material, reflecting the results of the world's leading climate scientists.

Yours sincerely,

Director of the Norbert Wiener Center

  • A Milestone for Carbon Dioxide in the Atmosphere
    One of the world's most important sentinel sites for measuring levels of carbon dioxide in the atmosphere, at Mauna Loa, Hawaii, reported that levels had recently risen above the symbolically important figure of 400 parts per million, and were likely to stay that way "for the indefinite future."

  • An Introductory Global CO2 Model
    W. E. Schiesser

  • Adapting to climate change a major challenge for forests
    Climate change is happening so quickly that a question mark hangs over whether forests can adapt accordingly without human interference and can continue to perform their various functions such as timber production, protection against natural hazards and providing a recreational space for the public.

  • What was "unprecedented" about Paris climate agreement?
    In December 2015, more than 190 countries, representing the source of more than 95 percent of global greenhouse gas emissions, met in France for the United Nations Climate Change Conference. Together, they crafted the Paris Agreement on Climate Change. "It's the first time essentially all the countries of the world have agreed to a common framework for addressing the problem of climate change," says Andrew Light, University Professor of Philosophy and Public Policy and director of the Institute for Philosophy and Public Policy at George Mason University.

  • Polar vortex shifting due to climate change, extending winter, study finds
    Global warming could be making winters in eastern North America even longer, according to a new study. The study finds that, because of sea ice loss in the Arctic, the polar vortex is shifting and temperatures are turning colder during March.

  • The Plastic Earth
    Jerry Mitrovica connects the planet's dynamic history to climate change. The weight of ice sheets in polar regions can actually flatten the earth's rocky mantle, altering the speed of the planet's rotation and changing sea levels.

  • Spatial and temporal distribution of mass loss from the Greenland Ice Sheet since AD 1900
    The Greenland Ice Sheet (GIS) is losing mass at an accelerating rate, contributing to global sea level rise. But are the present rates unusual, compared to twentieth-century variability? It has been difficult to answer this question because of the shortage of observations before the late twentieth century. Kurt Kjaer and colleagues address this data gap by analysing a collection of aerial photographs taken in the 1980s.

  • Assessing the Global Climate in May 2016
    The globally averaged temperature over land and ocean surfaces for May 2016 was the highest for the month of May in the NOAA global temperature dataset record, which dates back to 1880.

  • 2016 on pace to be the hottest year on record
    The new data shows that May was the thirtieth consecutive month to have soaring global temperatures across land and sea surfaces. This is the longest and hottest streak since temperature record-keeping began in 1880, according to NOAA.

  • U.S. and Canada pledge to cut methane emissions as part of broad climate change agreement
    President Obama and Canadian Prime Minister Justin Trudeau on Thursday announced a wide range of environmental initiatives to combat climate change, expand renewable energy and protect a fragile and remote region important to both nations -- the Arctic.

  • CLIMATE ACTION 2016 FORUM
    University of Maryland was a co-host of the United Nations-sponsored "Climate Action 2016" summit in Washington, D.C. for some 600 invited leaders from around the world. This summit was preceded by a "Climate Action Forum" on our campus that drew over 500 participants from the state and beyond.

  • CLIMATE ACTION 2016
    Climate change is the defining issue of our age. The landmark Paris Agreement reached last December commits all countries to holding global temperature rise to "well below 2 degrees Celsius". This feat will require economy-wide global and national transformations. A robust, multi-sector response will be a key component of this solution to pivot societies toward a more sustainable future for all - the future we want.

  • Scientists say Antarctic melting could double sea level rise. Here's what that looks like.
    In a groundbreaking climate change study, scientists have found that by neglecting to include the melting of Antarctica, we have vastly underestimated the potential for sea level rise over the next 80 years - and beyond.

  • The International Journal of Climate Change: Impacts and Responses
    The International Journal of Climate Change: Impacts and Responses seeks to create an interdisciplinary forum for discussion of evidence of climate change, its causes, its ecosystemic impacts, and its human impacts. The journal also explores technological, policy, strategic, and social responses to climate change.

  • 2015 smashes 2014's global temperature record.
    According to NASA and NOAA data 2015 was the hottest year ever.

  • Altering Course: Why the United States may be on the cusp of an energy revolution.
    "Of the nearly 100 quadrillion British thermal units of energy (BTUs) used each year in the United States, 61 quads are wasted. That is not a moral judgment, or a commentary on insufficient conservation (poor insulation, idling cars, people failing to turn off lights when they leave a room). It is, as Mara Prentiss notes, predominantly fundamental physics: the fuel is burned, but less than 50 percent performs useful work."

  • Inside Exxon's Great Climate Cover-Up: From Early Climate Change Researcher to Epic Climate Denier.
    A new report by InsideClimate News reveals how oil giant ExxonMobil's own research confirmed the role of fossil fuels in global warming decades ago. By 1977, Exxon's own senior experts had begun to warn the burning of fossil fuels could pose a threat to humanity.

  • Outsourcing Manufacturing to China Results in High CO2 Emissions.
    Despite the increasingly fervent debate regarding the trade relationship between China and the United States and its implications for the global political environment, it is evident that manufacturing goods in China and shipping them to developed countries has real-world consequences, particularly for the environment. University of Maryland researchers, in collaboration with others, have begun to quantify the magnitude of those impacts.

  • AMS Bulletin book review of Mathematics and climate.
    Gerald R. North reviews Mathematics and climate, by Hans Kaper and Hans Engler. North writes, "... a successful attempt in a brief survey to bring the world of climate science to the attention of aspiring and mature mathematicians, physicists, and engineers."

  • Climate Change Demands Marshall Plan Levels of Response
    Naomi Klein writes: "If we treat climate change as the crisis it is, we don't just have the potential to avert disaster but could improve society in the process."

  • Climate Crisis, the Deindustrialization Imperative and the Jobs vs. Environment Dilemma
    Richard Smith, Truthout: To prevent wholesale global ecological collapse we must radically retrench and close down swathes of unsustainable industries in the North, sustainably industrialize the South, and "converge and contract" around a sustainable mode of life within the framework of a global eco-socialist economy.

  • Modeling the impact of climate change on tropical moist forest dynamics: a hierarchical Bayesian approach
    There will be a Colloquium at Georgetown University in Washington DC on climate change.
    SPEAKER: Romain Gaspard, CNRS, Université Antilles-Guyane
    ABSTRACT: Identifying, quantifying and predicting the impact of climate change on tropical moist forest dynamics is becoming a matter of urgency. Growth and mortality are the two main processes driving population dynamics. Although these processes are not independent, they are generally modeled separately. In this work we develop a joint growth and mortality model for tropical moist forests that incorporates a set of climatic variables, functional traits and interactions. A Bayesian method is used to select relevant covariates and to estimate the model parameters. This modeling approach formalizes a complex ecological problem and offers a mathematical framework for tropical ecologists to deal with uncertainties at the community level, especially for earlier data with incomplete botanical determinations. The model is applied to a 30-year dynamic data obtained at the Paracou experimental site in French Guiana. We identified three major climatic drivers and found differential species responses according to their functional traits.

  • Oligarchy and Climate Change: A Catastrophic Coincidence
    Naomi Klein writes: "It is our great collective misfortune that the scientific community made its decisive diagnosis of the climate threat at the precise moment when an elite minority was enjoying more unfettered political, cultural, and intellectual power than at any point since the 1920s."

  • Democracy Now! -- Climate Change
    Democracy Now! has long covered the issue of climate change. They have reported from the U.N. Climate Change Conferences in Warsaw, Doha, Durban, Canc�n, and Copenhagen, and from the World Peoples� Summit on Climate Change hosted by Bolivia. They have interviewed many of the world�s top scientists, writers, policy makers, activists, indigenous leaders and academics on the issue. They continue to follow the environmental movements to directly confront the root causes of global warming, and to advocate for climate justice, and sustainable alternatives.
