#President Obama to Announce Climate Change Plan Today President Barack Obama will announce a comprehensive plan to reduce greenhouse gas emissions in a highly anticipated speech today (June 25) according to senior White house officials.
Reducing emissions The president's plan will direct the Environmental Protection Agency (EPA) to establish standards for greenhouse gas emissions for new and existing power plants.
Currently existing plants contribute about 40 percent of carbon emissions in the United states. In 2009 Obama pledged to reduce greenhouse gas emissions below 2005 levels by the year 2020.

#Reducing Greenhouse Gas Emissions Could Prevent Premature Deaths Reducing the flow of the greenhouse gases that spur global warming could prevent up to 3 million premature deaths annually by the year 2100
Greenhouse gases such as carbon dioxide trap heat helping warm the globe. The surge in carbon dioxide levels due to human activity since the Industrial revolution is now causing an overall warming of the planet that is having impacts around the globe.
Past studies have analyzed how reductions in greenhouse gas emissions would also improve air quality. 5 Ways Climate Change Affects Your Health
The researchers found that aggressively reducing greenhouse gas emissions could help prevent 300000 to 700000 premature deaths annually byâ the year 2030 two-thirds
We found reducing greenhouse gases could lead to a pretty striking reduction in air pollutants
and our study suggests serious benefits to reducing greenhouse gases in addition to helping slow down climate change West said.
but here we show that reducing greenhouse gas emissions can have near-term local benefits for health as well
In the future researchers can analyze the impacts of efforts to intentionally improve air quality as well as reduce greenhouse gas emissions West said.

Field samples and greenhouse experiments suggest these gold particles which exist at concentrations not harmful to the trees are absorbed by the roots
While there is a global consensus to cut greenhouse gasses many approaches look to solve the crisis over decades
If society waits a decade to curb greenhouse gasses such effects will be far stronger than they are today.
Third in the U s. greenhouse-gas emissions have declined recently from their peak in 2007. This was first due to the global recession
Methane is a much more powerful greenhouse gas than CO2. Depending on the leakage rate moving from coal to natural gas could fail to provide any climate benefits for 50 or even 100 years.
Finally some critics of immediate action to reduce greenhouse gasses point out that technological innovation will bring down the costs of clean energy
And if nations wait to address greenhouse gasses there will be a larger amount of high-carbon infrastructure to replace increasing future costs.
The team then collected scale insect egg sacs from both hot and cool zones and incubated them in hot and cool greenhouses.
In the hot greenhouse the egg sacs from the warmest urban zones produced almost four times as many insects as the egg sacs from cooler urban zones.
#Urbanization Can Actually Reduce Greenhouse Gas Emissions (Op-Ed) Chris Busch is director of research and Hallie Kennan is a research assistant atâ Energy Innovation:
Because urban centers can be a leading source for greenhouse-gas emissions low-carbon urban design can be a crucial tool for combatting rising emissions levels.
Well-designed cities cut greenhouse gas emissions in three ways: They get people out of cars by enabling walking biking and public transit;
which has per capita greenhouse gas emissions about two-thirds below the U s. national average. The figure above compares emissions for cities and the countries in
which they are located ordered according to national per-capita greenhouse gas emissions. It shows that urban residents often have lower emissions per person than national averages for home countries.
As a result transportation-related greenhouse gas emissions in Denver are more than four times larger than New york's. In the figure the four cities in developing countries do not have lower emissions per person compared to their nation's national average.
Some 250 million years ago during the late Permian and early Triassic the world was a greenhouse much hotter than it is today.
Most scientists attributed this wetter weather to the rise in greenhouse gases such as carbon dioxide in the atmosphere.
if the levels of greenhouse gas emissions are reduced not and nations have failed to address the myriad challenges of climate change scientists say Earth's fragile ecosystem could be in serious jeopardy.
But most of the nations with the fastest growing populations have far lower per capita greenhouse gas emissions.
which emit large amounts of greenhouse gases that linger in the atmosphere. This flurry of activity has taken a toll on the planet.
and China as they've industrialized countries that are populous and poor can experience a rapid rise in greenhouse gas emissions.
Since 2000 China's energy-related greenhouse gas emissions have increased at an average rate of more than 10 percent each year according to the Harvard Project on International Climate Agreements
While these types of resource taxes have been suggested as an incentivized way to reduce greenhouse gas emissions they remain politically divisive.
According to an analysis by Cascio the greenhouse gas emissions generated by the production of cheeseburgers in the United states each year is about equal to the greenhouse gas emissions from 6. 5 million to 19.6 million SUVS over a year (There are about 16 million

#What Are Greenhouse Gases? Behind the struggle to address global warming and climate change lies the increase in greenhouse gases in our atmosphere.
A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation thereby trapping and holding heat in the atmosphere.
By increasing the heat in the atmosphere greenhouse gases are responsible for the greenhouse effect which ultimately leads to global warming.
The sun bombards Earth with enormous amounts of radiation which strike Earth's atmosphere in the form of visible light plus ultraviolet (UV) infrared (IR)
The balance between incoming and outgoing radiation keeps Earth's overall average temperature at about 59 F 15 C). This exchange of incoming and outgoing radiation that warms Earth is referred often to as the greenhouse effect because a greenhouse works in much
Incoming UV radiation easily passes through the glass walls of a greenhouse and is absorbed by the plants
and is trapped inside warming the greenhouse. The gases in the atmosphere that absorb radiation are known as greenhouse gases (sometimes abbreviated as GHG)
because they are largely responsible for the greenhouse effect. The greenhouse effect in turn is one of the leading causes of global warming.
The most significant greenhouse gases are water vapor (H2o) carbon dioxide (CO2) methane (CH4) and nitrous oxide (N2o) according to the Environmental protection agency (EPA.
and are considered also greenhouse gases. Though they are present in very small concentrations they trap heat very effectively making them high global-warming potential (GWP) gases.
and aerosol propellants until they were phased out by international agreement are also greenhouse gases. Three factors affect the degree to
which any greenhouse gas will influence global warming: Carbon dioxide has a significant impact on global warming partly because of its abundance in the atmosphere:
In 2011 CO2 composed 84 percent of U s. greenhouse emissions according to the EPA. Additionally CO2 stays in the atmosphere for thousands of years.
Some greenhouse gases like methane are produced through agricultural practices including livestock manure management. Others like CO2 largely result from natural processes like respiration and from the burning of fossil fuels like coal oil and gas.
In the United states like most other industrialized nations burning fossil fuels is the single greatest manmade source of greenhouse gases.
According to the EPA the production of electricity is the source of 33 percent of U s. greenhouse gas emissions.
Transportation is a close second contributing about 28 percent of U s. greenhouse gas emissions. Almost all cars trucks ships trains and airplanes run on gasoline or diesel fuels.
Manufacturing and other industries contribute about 20 percent of U s. greenhouse gas emissions followed by residential and commercial sources (11 percent) and agriculture (8 percent.
and other land-use practices offset some of these greenhouse gas emissions according to the EPA. Because trees and other plants absorb CO2 from the atmosphere they reduce our overall greenhouse gas emissions by roughly 14 percent.
Worldwide however the output of greenhouse gases is a source of grave concern: From the time the Industrial revolution began to the year 2009 atmospheric CO2 levels have increased almost 38 percent
and methane levels have increased a whopping 148 percent according to NASA and most of that increase has been in the past 50 years.

because the same process keeps a greenhouse warm during cold weather: Solar radiation is trapped by the glass walls of a greenhouse heating the greenhouse
and keeping its plants warm throughout the winter. The atmospheric gases primarily responsible for the greenhouse effect are known as greenhouse gases
and include water vapor carbon dioxide (CO2) methane and nitrous oxide. Not all greenhouse gases are the same:
methane for example has roughly 21 times the heat-trapping ability of carbon dioxide according to the EPA.
Reducing greenhouse gas emissions is perhaps the most fundamental way to address global warming and decreasing the rate at
More sustainable transportation options such as mass transit and alt-fuel vehicles will also reduce the amount of greenhouse gases in the atmosphere.
the average temperature on Venus is about 864 degrees F (462 degrees C). The exchange of incoming and outgoing radiation that warms the Earth is referred often to as the greenhouse effect because a greenhouse works in much the same way.
Incoming UV radiation easily passes through the glass walls of a greenhouse and is absorbed by the plants
and is trapped inside thus warming the greenhouse. This effect lets tropical plants thrive inside a greenhouse even during a cold winter.
A similar phenomenon takes place in a car parked outside on a cold sunny day.
The gases in the atmosphere that absorb radiation are known as greenhouse gases because they're largely responsible for the greenhouse effect.
These greenhouse gases include water vapor carbon dioxide (CO2) methane nitrous oxide (N2o) and other gases according to the Environmental protection agency (EPA.
Since the dawn of the Industrial revolution in the early 1800s the burning of fossil fuels like coal oil and gasoline have increased greatly the concentration of greenhouse gases in the atmosphere especially CO2 according to NASA.
CO2 and other greenhouse gases act like a blanket absorbing IR radiation and preventing it from escaping into outer space.
The greenhouse effect combined with increasing levels of greenhouse gases and the resulting global warming is expected to have profound implications according to the near-universal consensus of scientists.

#EPA Aims To Slash Power plant CO2 by 30 Percent Nearly every state in the U s. now has a greenhouse gas emissions reduction goal to meet under the Obama administration's new Clean
The EPA rule is part of the White house s broader Climate Action Plan announced last year that includes a number of steps to reduce greenhouse gas emissions
but don't go far enough in curbing climate change-driving greenhouse gas emissions. Overall if the proposed rules survive possible legal challenges
but they set national policy that greenhouse gas emissions need to be reduced. My own feeling about all this is that the policy of trying to reduce the use of fossil fuels by regulating greenhouse gases is not going to work
because we're not just talking about the U s . but China and India he said adding that the solution exists in developing renewable energy technologies that drive fossil fuels from the marketplace.
#But Cornell University earth and atmospheric sciences professor Louis Derry said Monday that not only will the new rules be effective at reducing U s. overall greenhouse gas emissions they'll boost the use of natural gas
Recycling plant nutrients to the field such as in biogas residue can contribute to lower greenhouse gas emissions from crop production.

The fact is the U s. beef industry produces beef with lower greenhouse gas emissions than any other country.
These emissions among other greenhouse gases heated the globe by about 11 degrees Fahrenheit (6 degrees Celsius) over roughly 20000 years.
Owing to its size the forest absorbs 1. 5 billion tons of CO2 from the atmosphere every year making it the largest terrestrial sink of this greenhouse gas.
The process of deforestation is causing an addition of 1. 6 billion tons of CO2 to the atmosphere per year substantially increasing greenhouse gases.

and the need to reduce smoke pollution to minimise greenhouse gas emissions and protect human health.
A new landmark study in the journal Science found that the U s. Environmental protection agency's (EPA) inventory of greenhouse gases is undercounting total U s. methane emissions by roughly 50 percent.
In the years immediately after it's released methane is a potent greenhouse gas. It causes 86 times as much global warming over a 20-year period as carbon dioxide the single largest contributor to climate change.
According to our analysis at Energy Innovation the methane missing from the EPA's inventory in terms of the contribution to global warming over a 20-year time period would be equivalent to the greenhouse gas emissions of 252 coal power plants.
At the same time that the scientific community is finding evidence that methane is being undercounted the newly released draft version of the U s. EPA's national greenhouse-gas emission inventory presents data showing that methane emissions from natural gas
The EPA greenhouse gas inventory uses data from bottom up studies to develop emission factors for different components of the entire natural gas system from production (extraction from the ground) to processing transmission and distribution.
When it takes over ecosystems this invader causes soils to surrender their carbon and release it as greenhouse gas.
Its invasion may also be contributing to the rise in global greenhouse gases by altering soil composition.
Over time carbon is released as greenhouse gases carbon dioxide and methane when the matter is degraded by soil microbes.
A Carnegie mellon University study found that eating plant-based meals even just one day a week reduces more greenhouse gases than eating exclusively local foods every day (a practice some people admirably
At the top of the Spencer Gulf near Port Augusta in South australia Sundrop Farms is turning sunlight and seawater into fresh water and food inside greenhouses.
It harnesses the sun s energy to produce heat that is then used to desalinate seawater and supply freshwater to a greenhouse;
to power the greenhouse with a linked concentrated solar power plant; and to produce the heat needed to warm
(and cool) the greenhouse. It is by linking these different components that their individual cost disadvantages can be overcome:
Sundrop Farms now has a 0. 2 hectare greenhouse area producing 150 tonnes of tomatoes cucumbers and capsicums a year.
The project is currently being scaled-up 100-fold to encompass a 20-hectare greenhouse complex with associated desalination and concentrated solar power systems to produce 15000 tonnes of fresh produce each year.
