This is a lot of contaminated water – also known as leachate or garbage juice! This contaminated water is ten to 1,000 times more contaminated and damaging to the local surface and groundwater than sewage, although it contains few human disease organisms (pathogens) and much fewer than sewage.

All nations also produce huge quantities of scrap tires. Waste scrap tires present landfill problems. They are hard to compact, may rise to the surface over time in poorly compacted waste and provide dangerous breeding grounds for mosquitoes and rats, in the water which collects in them. They also unfortunately do not disintegrate to reduce their volume in stockpiling.

Also if industrial hazardous wastes are landfilled the waste materials that will often be found in the site will be such that the sites will later be classed as contaminated land and do not meet the contaminated soil criteria. This is to be expected where regulatory control is poor but the cost to the community is hugely greater than paying for good regulation in the first place.

It is not realized by many in the community at large that waste prevention and recycling are critical to reducing or stopping climate change. Waste-to-energy (WTE) plants create heat and electricity from burning mixed solid waste. Because of high corrosion in the boilers, the steam temperature in WTE plants may end up being less than 400 degrees Celsius. This has to be avoided because at these temperatures of combustion many hazardous by-products of incomplete combustion will be present which are very harmful to the local environment and the health of future occupants, if not cleaned up.

But, the adoption of large scale waste prevention and recycling will help address global climate change by decreasing the amount of greenhouse gas emissions and saving energy (US Environmental Protection Agency).

The fact is that global warming, also known as the greenhouse gas effect, remains controversial in many quarters. Many still question the basis of the prediction of climate change. However, Under the 1997 Kyoto Protocol, the United States agreed in principle to reduce its emissions of greenhouse gases to somewhat below 1990 levels by the period 2008-2012.

In 1997 global cooling was a big environmental worry and an issue back then, but few paid attention to that either, and the concerns were soon found to be unfounded. The perspective in global cooling is similar to the way people view global warming now.

Landfill methane is an excellent and frequently untapped resource. Most times gases are simply flared or burned in the atmosphere, which is much less contributory to the greenhouse gas build-up which worries us all, than just letting the methane (landfill gas) escape without flaring. Landfill methane is typically flared in the developed nations, and almost never flared in the developing world\’s nations.

Opinions about landfill gas as an emissions problem, and even the producer of significant greenhouse gas emissions vary across the US. We have been made aware that state regulators consider methane to be a minor problem in New Mexico, due to the dry climate. However, Albuquerque is treating at least one serious methane problem with a high priority. State-by-state analyses nevertheless, do show a large and untapped potential for biomass-fired electricity generation. A very separate question, of course, is how much of this potential makes financial, environmental, or political sense.

However, interest in the use of landfill gas to fuel electricity generation is growing. Landfill methane is collected at a growing number of landfill sites and burned for energy production which mitigates the global warming effect of the methane as well as producing electricity and/or heat.

The vast plume of contamination from factories, fires, cars and deforestation contains some particles that reflect sunlight away from the earth, cutting its ability to heat the earth.

“One of the impacts of this atmospheric brown cloud has been to mask the true nature of global warming on our planet,” United Nations Environment Programme head Achim Steiner said at the launch in Beijing of a new report on the phenomenon.

The amount of sunlight reaching earth through the murk has fallen by up to a quarter in the worst-affected areas and if the brown cloud disperses, global temperatures could rise by up to 2 degrees Celsius.

But the overall effect of slowing climate change is not the silver lining to a dark cloud that it appears to be.

The choking soup of pollutants may hold temperatures down overall, but the mix of particles means it is also speeding up warming in some of the most vulnerable areas and exacerbating the most devastating impacts of higher temperature.

<!--adsense#global-->

The complex impact of the cloud, which tends to cool areas near the surface of the earth and warm the air higher up, is believed to be causing a shortening of the monsoon season in India while increasing flooding there and in southern China.

Soot from the cloud is also deposited on glaciers, which are at the centre of environmentalists’ and politicians’ concerns because they feed Asia’s key rivers and provide drinking water for billions who live along them.

Scientists are still studying the impact on crops, but possible problems include falling harvests because of less energy for photosynthesis and higher ozone concentrations.

There may also be damage from acidic and toxic particles in the cloud that land on plants, and wider changes to weather patterns may dry up or flood fields.

“The emergence of the atmospheric brown cloud problem is expected to further aggravate the recent dramatic escalation of food prices and the consequent challenge for survival among the world’s most vulnerable populations,” the report said.

One consolation, however, is that if the world stopped emitting the particles that form the cloud, it could be expected to vanish in weeks, unlike many longer-lasting greenhouse gasses.

The ingredients that make up the cloud are little different from the smog that cloaks many of the world’s large cities, particularly in developing nations.

Although we do not know that most of the media in the U.S. , to record “once in a hundred years flood” West now seems to be every decade, more or less exactly what scientists had expected the heat.

A 2004 analysis by the NOAA National Climatic Data Center found a rise during the 20th century by rainfall, temperature, flow, heavy and very heavy rainfall and high flows in the East. “They found an increase of 14 percent” strong rainfall events “More than 2 inches in a day, and an increase of 20 percent” very heavy rainfall events, “best described as the largest Deluge-4 centimeters in a day. These rains are extremely exactly what was expected by warming comprehensive and scientific models.

Indeed, 2007 saw the second most extreme rainfall over the United States in the historical record, according to the NCDC climatic extremes Index (CEI). Here is a land of the percentage of the country (or two), much higher than normal proportion of precipitation derived from extreme 1-day precipitation events (extreme, which is equal to the higher percentile of tenth Deluge):

I do not know that our government has maintained an index extreme weather? Why do you have? The media does not write about it.

U. S. extreme climate index was created expressly to take a complicated subject ( “multiple climate change and multidimensional in the United States”) and to make them easier to understand for citizens and policy makers. As far in 1995, the analysis by the National Climatic Data Center showed that during the 20th century, the United States has suffered a statistically significant improvement in a variety of extreme weather events, which hopefully heating in general as more – and more – precipitation. Analysis concluded that the chances were only “5-10 percent” this increase was due to other factors that global warming, such as natural climate variability. “And since 1995, the climate has become more extreme .

I have followed this issue, the link between climate change and extreme weather events very closely – and yet, in 2006, we have not seen a single mention of the index in the media, or even a scientific paper on its initial For more than a decade. Global warming may be a hot topic, and in 2006 was the second year ever more extreme, but try a search on Google News “extreme weather Index” (the quotation marks) – do not get to all matches.

Story after story appearing in the mainstream media have no connection with any extreme weather, global warming and disconnected from man-made, a trend that eventually all our lives. The media should do a better job.

Extreme weather

Storm strength leading to extreme weather is increasing, such as the power dissipation index of hurricane intensity. Precipitation hitting the US from hurricanes has increased by 7% over the twentieth century. Some studies have found that the increase in sea surface temperature may be offset by an increase in wind shear, leading to little or no change in hurricane activity.

Increases in catastrophes resulting from extreme weather are mainly caused by increasing population densities, and anticipated future increases are similarly dominated by societal change rather than climate change. Vecchi and Soden find that wind shear, the increase of which acts to inhibit tropical cyclones, also changes in model-projections of global warming. The study does not make claims about the net effect on Atlantic and East Pacific hurricanes of the warming and moistening atmospheres, and the model-projected increases in Atlantic wind shear. Water levels are decreasing every day. (See also “Global warming?” in tropical cyclone)

Increased evaporation

Increasing water vapor at Boulder, Colorado.

As the climate grows warmer and the causes of global dimming are reduced, evaporation will increase due to warmer oceans. Scientists have found evidence that increased evaporation could result in more extreme weather as global warming progresses. The IPCC Third Annual Report says: “…global average water vapor concentration and precipitation are projected to increase during the 21st century. Pielke et al. (2008) normalized mainland U.S. hurricane damage from 1900–2005 to 2005 values and found no remaining trend of increasing absolute damage. There is no agreement as to whether this hurricane is linked to climate change, but one climate model exhibits increased tropical cyclone genesis in the South Atlantic under global warming by the end of the 21st century.

Glacier retreat and disappearance

Lewis Glacier, North Cascades, WA USA is one of five glaciers in the area that melted away

In historic times, glaciers grew during a cool period from about 1550 to 1850 known as the Little Ice Age. Subsequently, until about 1940, glaciers around the world retreated as the climate warmed. Glacier retreat declined and reversed in many cases from 1950 to 1980 as a slight global cooling occurred. This process has increased markedly since 1995.

^[40] Currently glacier retreat rates and mass balance losses have been increasing in the Andes, Alps, Pyrenees, Himalayas, Rocky Mountains and North Cascades.

Glacier runoff declines in the summer as glaciers decrease in size, this decline is already observable in several regions. In warmer and drier years, glaciers offset the lower precipitation amounts with a higher meltwater input.

It has to be acknowledged, however, that increased seasonal runoff of Himalayan glaciers led to increased agricultural production in northern India throughout the 20th century.

The Lewis Glacier, North Cascades pictured at right after melting away in 1990 is one of the 47 North Cascade glaciers observed and all are retreating. Like rivers flowing from an enormous lake, numerous outlet glaciers transport ice from the margins of the ice sheet to the ocean.

Retreat of the Helheim Glacier, Greenland

Glacier retreat has been observed in these outlet glaciers, resulting in an increase of the ice flow rate. Three glaciers that have been researched, Helheim, Jakobshavns and Kangerdlugssuaq Glaciers, jointly drain more than 16% of the Greenland Ice Sheet. Glacier retreat and acceleration is also apparent on two important outlet glaciers of the West Antarctic Ice Sheet.

Oceans

The role of the oceans in global warming is a complex one. Furthermore, as the temperature of the oceans increases, they become less able to absorb excess CO₂. Global warming is projected to have a number of effects on the oceans. Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification. Other possible effects include large-scale changes in ocean circulation.

Sea level rise

Sea level rise during the Holocene.

Sea level has been rising 0.2 cm/year, based on measurements of sea level rise from 23 long tide gauge records in geologically stable environments.

With increasing average global temperature, the water in the oceans expands in volume, and additional water enters them which had previously been locked up on land in glaciers, for example, the Greenland and the Antarctic ice sheets. Meanwhile, the estimated total ice melting rate over Greenland is –239 ± 23 cubic kilometers per year, mostly from East Greenland.
