A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Without greenhouse gases, the average temperature of Earth's surface would be about 15 °C (27 °F) colder than the present average of 14 °C (57 °F). In the Solar System, the atmospheres of Venus, Mars and Titan also contain gases that cause a greenhouse effect.
Human activities since the beginning of the Industrial Revolution (taken as the year 1750) have produced a 40% increase in the atmospheric concentration of carbon dioxide, from 280 ppm in 1750 to 400 ppm in 2015. This increase has occurred despite the uptake of a large portion of the emissions by various natural "sinks" involved in the carbon cycle.Anthropogenic carbon dioxide (CO2) emissions (i.e. emissions produced by human activities) come from combustion of carbon-based fuels, principally coal, oil, and natural gas, along with deforestation and soil erosion.
New York is a state in the Northeastern United States and is the United States' 27th-most extensive, fourth-most populous, and seventh-most densely populated state. New York is bordered by New Jersey and Pennsylvania to the south and Connecticut, Massachusetts, and Vermont to the east. The state has a maritime border in the Atlantic Ocean with Rhode Island, east of Long Island, as well as an international border with the Canadian provinces of Quebec to the north and Ontario to the west and north. The state of New York, with an estimated 19.8 million residents in 2015, is often referred to as New York State to distinguish it from New York City, the state's most populous city and its economic hub.
With an estimated population of nearly 8.5 million in 2014, New York City is the most populous city in the United States and the premier gateway for legal immigration to the United States. The New York City Metropolitan Area is one of the most populous urban agglomerations in the world. New York City is a global city, exerting a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment, its fast pace defining the term New York minute. The home of the United Nations Headquarters, New York City is an important center for international diplomacy and has been described as the cultural and financial capital of the world, as well as the world's most economically powerful city. New York City makes up over 40% of the population of New York State. Two-thirds of the state's population lives in the New York City Metropolitan Area, and nearly 40% live on Long Island. Both the state and New York City were named for the 17th century Duke of York, future King James II of England. The next four most populous cities in the state are Buffalo, Rochester, Yonkers, and Syracuse, while the state capital is Albany.
Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years). Climate change may refer to a change in average weather conditions, or in the time variation of weather around longer-term average conditions (i.e., more or fewer extreme weather events). Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have also been identified as significant causes of recent climate change, often referred to as "global warming".
Scientists actively work to understand past and future climate by using observations and theoretical models. A climate record—extending deep into the Earth's past—has been assembled, and continues to be built up, based on geological evidence from borehole temperature profiles, cores removed from deep accumulations of ice, floral and faunal records, glacial and periglacial processes, stable-isotope and other analyses of sediment layers, and records of past sea levels. More recent data are provided by the instrumental record. General circulation models, based on the physical sciences, are often used in theoretical approaches to match past climate data, make future projections, and link causes and effects in climate change.
Emission trading scheme? Cap and trade? What do these words mean? And how does it all contribute to reduced emissions of greenhouse gases? This animation shows how the scheme works.

An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe. Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons. The carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office. The visualization is a product of a simulation called a “Nature Run.” The Nature Run ingests real data on at...
In 2010 New York City added 54 million metric tons of carbon dioxide (equivalent) to the atmosphere, but that number means little to most people because few of us have a sense of scale for atmospheric pollution. Carbon Visuals (http://www.carbonvisuals.com) and Environmental Defense Fund (http://www.edf.org/climate/remaking-energy) wanted to make those emissions feel a bit more real - the total emissions and the rate of emission. Designed to engage the 'person on the street', this version is exploratory and still work in progress. Mayor Bloomberg's office has not been involved in the creation or dissemination of this video. NYC carbon footprint: 54,349,650 tons a year = 148,903 tons a day = 6,204 tons an hour = 1.72 tons a second At standard pressure and 59 °F a metric ton of carbon d...
http://www.edmonton.ca/thewaywegreen Join us as we demystify human-made climate change from greenhouse gas (GHG) emissions caused by burning fossil fuels, and explain how we have upset the long-term natural balance of climate. And learn what we can do to contribute to a global solution. This talk will explain, in lay language, how the "natural" atmospheric greenhouse effect has, until recently, kept climate in balance. Long-term natural variations in our climate will be explained, including how these are distinct from what we call anthropogenic global warming.

Brisbane Baylands Continued Public Hearing Specific topics include: Traffic, Noise, Air Quality, Greenhouse Gas Emissions, and Related Policy Issues
Around the world, urban areas are responsible for a large and growing percentage of human-caused greenhouse gas emissions. Because of this, mitigation actions in urban areas could contribute significantly to reducing greenhouse gas emissions. A key question for policymakers, however, is how best to achieve this mitigation potential. In this webinar, Pete Erickson of the Stockholm Environment Institute explored “vertically integrated” approaches to city-related greenhouse gas emissions, combining policy actions at all levels of government.
Webinar: States on the Hot Seat: State Efforts to Reduce Greenhouse Gas Emissions from Transportation 06/14/2016 Rebecca Lewis, Assistant Professor, University of Oregon
Sponsor: Georgetown Climate Center Event Summary: While opponents of climate action argue that U.S. commitments to greenhouse gas emissions reductions are unattainable or unlikely to be maintained, many U.S. states are taking action to make these reductions happen. Some are setting ambitious targets of their own, others are implementing new policies to cap emissions, still others are making striking commitments to deploy renewable energy and enact energy efficiency measures. This event will focus on states’ commitments to reducing greenhouse gas emissions, the role that federal policy plays in promoting further state action, and reasons to believe these efforts will continue.
