USA Global Warming and Climate Change

Thursday, January 17th, 2013

For many years, the United States government has been in denial about global warming; however, a new study mandated by congress, National Climate Assessment and Development Climate Assessment, highlights the impact of global warming on health, infrastructure, water supply, agriculture and in particular more volatile weather.

1. Global climate is changing now and this change is apparent across a wide range of observations. Much of the climate change of the past 50 years is primarily due to human activities.
2. Global climate is projected to continue to change over this century and beyond. The magnitude of climate change beyond the next few decades depends primarily on the amount of heat-trapping gases emitted globally, and how sensitive the climate is to those emissions.
3. U.S. average temperature has increased by about 1.5°F since record keeping began in 1895; more than 80% of this increase has occurred since 1980. The most recent decade was the nation’s warmest on record. U.S. temperatures are expected to continue to rise. Because human-induced warming is superimposed on a naturally varying climate, the temperature rise has not been, and will not be, smooth across the country or over time.
4. The length of the frost-free season (and the corresponding growing season) has been increasing nationally since the 1980s, with the largest increases occurring in the western U.S., affecting ecosystems and agriculture. Continued lengthening of the growing season across the U.S. is projected.
5. Precipitation averaged over the entire U.S. has increased during the period since 1900, but regionally some areas have had increases greater than the national average, and some areas have had decreases. The largest increases have been in the Midwest, southern Great Plains, and Northeast. Portions of the Southeast, the Southwest, and the Rocky Mountain states have experienced decreases. More winter and spring precipitation is projected for the northern U.S., and less for the Southwest, over this century.
6. Heavy downpours are increasing in most regions of the U.S., especially over the last three to five decades. Largest increases are in the Midwest and Northeast. Further increases in the frequency and intensity of extreme precipitation events are projected for most U.S. areas.
7. Certain types of extreme weather events have become more frequent and intense, including heat waves, floods, and droughts in some regions. The increased intensity of heat waves has been most prevalent in the western parts of the country, while the intensity of flooding events has been more prevalent over the eastern parts. Droughts in the Southwest and heat waves everywhere are projected to become more intense in the future.
8. There has been an increase in the overall strength of hurricanes and in the number of strong (Category 4 and 5) hurricanes in the North Atlantic since the early 1980s. The intensity of the strongest hurricanes is projected to continue to increase as the oceans continue to warm; ocean cycles will also affect the amount of warming at any given time. With regard to other types of storms that affect the U.S., winter storms have increased slightly in frequency and intensity, and their tracks have shifted northward over the U.S. Other trends in severe storms, including the numbers of hurricanes and the intensity and frequency of tornadoes, hail, and damaging thunderstorm winds are uncertain and are being studied intensively.
9. Global sea level has risen by about 8 inches since reliable record keeping began in 1880. It is projected to rise another 1 to 4 feet by 2100.
10. Rising temperatures are reducing ice volume and extent on land, lakes, and sea. This loss of ice is expected to continue.
11. The oceans are currently absorbing about a quarter of the carbon dioxide emitted to the atmosphere annually and are becoming more acidic as a result, leading to concerns about potential impacts on marine ecosystems.

Increased Need for Climate Action

Thursday, November 8th, 2012

Fred Krupp President of the Environmental Defense Fund wrote, “Congratulations to President Obama on his re-election to a second term, and to all of those who will be serving in the 113th Congress. We look forward to working with them to solve our country’s most pressing environmental problems, including global climate change. As the President declared last night, ‘we want our children to live in an America … that isn’t threatened by the destructive power of a warming planet.’

Previously, Nat Keohane Vice President of the EDF, stated, “…The magnitude and urgency of the challenge have not diminished. If we needed any reminder of that fact, Hurricane Sandy should have provided it—especially coming on the heels of devastating drought, record-breaking temperatures through the spring and summer, and a record low in the extent of Arctic sea ice.

“…Addressing global warming will be politically challenging—but presidents are not elected to do the easy things, and political realities are not set in stone. The first step to tackling climate change is to start talking about it, not just once in a while but routinely, as a fact of life rather than a special-interest issue.

“The next president must build public understanding of the issue, connecting the dots between our own actions and the extreme weather we are already seeing. He must engage folks from across the political spectrum on the possible solutions. And he must be willing to spend political capital to get something done.”
“Exit polls confirm that for millions of American voters, Hurricane Sandy and climate change were decisive factors in this election. As the historic storm just reminded us, we have no time to waste; we must get serious about climate solutions in order to protect our loved ones and communities from terrible impacts — extreme weather disasters, droughts, heat waves, and other dangerous consequences of global warming. Especially in the wake of Sandy, which demonstrated that doing nothing about climate change is much costlier than taking action, this issue clearly should be a top priority for our leaders in government.”

Global Warming and Climate Change: Why the USA is Mute

A Non-Issue in Campaign

During the 2012 presidential campaign, neither President Obama nor Mitt Romney, his Republican challenger, spoke much about climate change, despite the fact that both men agree that the world is warming and that humans are at least partly to blame. None of the moderators of the four general-election debates asked about climate change, nor did any of the candidates broach the topic.

Throughout the campaign, Mr. Obama and Mr. Romney have seemed most intent on trying to outdo each other as lovers of coal, oil and natural gas — the very fuels most responsible for rising levels of carbon dioxide in the atmosphere.

Mr. Obama has supported broad climate change legislation, financed extensive clean energy projects and pushed new regulations to reduce global warming emissions from cars and power plants. But neither he nor Mr. Romney has laid out during the campaign a legislative or regulatory program to address the fundamental questions arising from one of the most vexing economic, environmental, political and humanitarian issues to face the planet

As governor of Massachusetts, Mr. Romney considered joining a regional cap-and-trade system, then abandoned it because of uncertainty over costs. He has opposed Mr. Obama’s steps to regulate emissions from power plants and vehicles. He has said he would reverse Mr. Obama’s air quality regulations and would renegotiate the auto efficiency standard of 54.5 miles per gallon by 2025 that automakers agreed to this year.

ABOUT GLOBAL WARMING

Global warming has become perhaps the most complicated issue facing world leaders. Warnings from the scientific community are becoming louder, as an increasing body of science points to rising dangers from the ongoing buildup of human-related greenhouse gases — produced mainly by the burning of fossil fuels and forests.

Global emissions of carbon dioxide jumped by the largest amount on record in 2010, upending the notion that the brief decline during the recession might persist through the recovery. Emissions rose 5.9 percent in 2010, according to the Global Carbon Project, an international collaboration of scientists. The increase solidified a trend of ever-rising emissions that scientists fear will make it difficult, if not impossible, to forestall severe climate change in coming decades.

However, the technological, economic and political issues that have to be resolved before a concerted worldwide effort to reduce emissions can begin have gotten no simpler, particularly in the face of a global economic slowdown.

For almost two decades, the United Nations has sponsored annual global talks, the United Nations Framework Convention on Climate Change, an international treaty signed by 194 countries to cooperatively discuss global climate change and its impact. The conferences operate on the principle of consensus, meaning that any of the participating nations can hold up an agreement.

The conflicts and controversies discussed are monotonously familiar: the differing obligations of industrialized and developing nations, the question of who will pay to help poor nations adapt, the urgency of protecting tropical forests and the need to rapidly develop and deploy clean energy technology.

But the meetings have often ended in disillusionment, with incremental political progress but little real impact on the climate. The negotiating process itself has come under fire from some quarters, including the poorest nations who believe their needs are being neglected in the fight among the major economic powers. Criticism has also come from a small but vocal band of climate-change skeptics, many of them members of the United States Congress, who doubt the existence of human influence on the climate and ridicule international efforts to deal with it.
