YUMMY SOLUTION TO STOP GLOBAL WARMING

If any of you feel horrible for disturbing your diet and eating fatty deep fried food, don’t feel so! You are actually helping to curb climate change in a small way.

Fatty acids released into the air from cooking may contribute to the formation of clouds that cool the climate, say scientists.

Fried, fatty and utterly delicious food may have an adverse impact on your waistline, but it is defiantly assisting in reducing global warming.

A new study shows that the fatty acids released into the air while frying food may help clouds that cool the atmosphere to form.

CAN WE PUT A HALT ON GLOBAL WARMING?

The evidence that humans are causing global warming is strong, but the question of what to do about it remains controversial. Economics, sociology, and politics are all important factors in planning for the future.

Even if we stopped emitting greenhouse gases (GHGs) today, the Earth would still warm by another degree Fahrenheit or so. But what we do from today forward makes a big difference. Depending on our choices, scientists predict that the Earth could eventually warm by as little as 2.5 degrees or as much as 10 degrees Fahrenheit.

Scientists have rather major plans to keep the earth surface cool.

IS INDIA DROWNING IN GARBAGE?

The old saying out of sight, out of mind definitely does not apply when it comes to getting rid of personal waste.

Garbage, though unseen, can have real impacts on the environment when it is not properly disposed of. Burying rubbish as a means of disposal is one the oldest and most common forms of waste management, but unfortunately, the impact that landfill sites have on the environment are huge.

The environmental problems caused by landfills are numerous. There are no arguments over the assertion that there are many things that contribute to the environmental problem of landfills. The negative effects are most commonly placed into two distinct categories: atmospheric effects and hydrological effects. While these effects are both of equal importance, the specific factors that drive them are important to understand on an individual basis.

The mixture of chemicals like bleach and ammonia in landfills can produce toxic gases and odor that can significantly impact the quality of air in the vicinity of the landfill. Hydrogen sulphide produced in landfills smells similar to rotten eggs.

Travelling from central Delhi towards Ghazipur in the city’s east, the first warning that you get of the approaching landfill is the sight of circling birds of prey. The mound of waste itself becomes visible much before one is assaulted by its stench. Smoke rises steadily from the pile, as the decomposing waste generates highly combustible methane gas. Three of the four stinking waste mountains (landfills) are long overdue for closure and there are no fresh landfills available to take in the current daily discard of 9,000 tonnes. By 2020, the Capital needs an additional area of 28 sqkm, more than the entire spread of Lutyen’s Bungalow Zone, to dump 15,000 tonnes of garbage daily.

Aside from the various types of gases that can be created by these landfills, dust and other forms of non-chemical contaminants can make their way into the atmosphere. This contributes further to the air quality issue which plagues modern landfills.

When it comes to waste management in India, little is the way it’s meant to be. Mumbai literally raised a stink recently when a fire broke out at the Deonar landfill, severely compromising air quality in the city. The national capital too is fast becoming one huge garbage dump with civic body sanitation workers on a strike to protest against non-payment of salaries.

Delhi has miserably failed to manage its waste load. Only 15 per cent of R1,350 crore that the three corporations spend on waste management and sanitation is spent on actual disposal. The rest goes into collection and transportation.

The authorities must ensure segregation and promote composting and recycling. They must quantify waste generation for setting effective reduction targets. But don’t wait for the authorities to do everything. From segregation, recycling to composting — you can make a difference. And, yes, consume and waste less. Now is the time.

DOES OVER-POPULATION IMPACT GLOBAL WARMING?

According to the United Nations Population Fund, human population grew from 1.6 billion to 6.1 billion people during the course of the 20th century. (Think about it: It took all of time for population to reach 1.6 billion; then it shot to 6.1 billion over just 100 years.) During that time emissions of CO2, the leading greenhouse gas, grew 12-fold. And with worldwide population expected to surpass nine billion over the next 50 years, environmentalists and others are worried about the ability of the planet to withstand the added load of greenhouse gases entering the atmosphere and wreaking havoc on ecosystems down below.

In 1970, when worldwide greenhouse gas emissions had just begun to transgress the sustainable capacity of the atmosphere, the world population was about 3.7 billion; today it’s about 6.1 billion — an increase of 86 percent.

In that same period, worldwide emissions from fossil fuels rose from about 14 billion tons to an estimated 29 billion tons — an increase of 107 percent.

Population growth is not the direct cause of global warming, burning fossil fuels is.

Where some of the confusion comes from is that CO2 emissions are reasonably well correlated to population.

It’s not a one-to-one relationship, but there is a solid relationship. For a couple of centuries, more people meant a great deal more CO2 which more closely tracked gross domestic product on a one-to-one ratio. As countries became richer, that was reflected in their GDP and also in their reduction in fertility. More GDP equals flattening population but still increasing CO2 emissions.

“Population, global warming and consumption patterns are inextricably linked in their collective global environmental impact,” reports the Global Population and Environment Program at the non-profit Sierra Club. “As developing countries’ contribution to global emissions grows, population size and growth rates will become significant factors in magnifying the impacts of global warming.”

According to the Worldwatch Institute, a nonprofit environmental think tank, the overriding challenges facing our global civilization are to curtail climate change and slow population growth. “Success on these two fronts would make other challenges, such as reversing the deforestation of Earth, stabilizing water tables, and protecting plant and animal diversity, much more manageable,” reports the group. “If we cannot stabilize climate and we cannot stabilize population, there is not an ecosystem on Earth that we can save.”

Many population experts believe the answer lies in improving the health of women and children in developing nations. By reducing poverty and infant mortality, increasing women’s and girls’ access to basic human rights (health care, education, economic opportunity), educating women about birth control options and ensuring access to voluntary family planning services, women will choose to limit family size.

 

 

OCEAN ACIDIFICATION

Climate Change isn’t the only consequence of carbon pollution from fossil fuels. If driving global temperature rise wasn’t enough, increased carbon in our atmosphere is also behind the rapid acidification of our world’s oceans.

But what exactly is ocean acidification?

When carbon dioxide (CO2) is absorbed by seawater, chemical reactions occur that reduce seawater pH, carbonate ion concentration, and saturation states of biologically important calcium carbonate minerals. These chemical reactions are termed “Ocean Acidification” or “OA” for short.

Oceans becoming more acidic after the Industrial Revolution are no accident. As humans burn more and more fossil fuels, the concentration of carbon dioxide in our atmosphere continues to rise, driving climate change and making both air and sea temperatures hotter and hotter.

Ocean acidification is expected to impact ocean species to varying degrees. Photosynthetic algae and sea grasses may benefit from higher CO2 conditions in the ocean, as they require CO2 to live just like plants on land. On the other hand, studies have shown that a more acidic environment has a dramatic effect on some calcifying species, including oysters, clams, sea urchins, shallow water corals, deep sea corals, and calcareous plankton. When shelled organisms are at risk, the entire food web may also be at risk. Today, more than a billion people worldwide rely on food from the ocean as their primary source of protein. Many jobs and economies in the U.S. and around the world depend on the fish and shellfish in our oceans.

Ocean acidification is an emerging global problem. Over the last decade, there has been much focus in the ocean science community on studying the potential impacts of ocean acidification. Since sustained efforts to monitor ocean acidification worldwide are only beginning, it is currently impossible to predict exactly how ocean acidification impacts will cascade throughout the marine food chain and affect the overall structure of marine ecosystems. With the pace of ocean acidification accelerating, scientists, resource managers, and policymakers recognize the urgent need to strengthen the science as a basis for sound decision making and action.

Future predictions indicate that the oceans will continue to absorb carbon dioxide and become even more acidic. Estimates of future carbon dioxide levels, based on business as usual emission scenarios, indicate that by the end of this century the surface waters of the ocean could be nearly 150 percent more acidic, resulting in a pH that the oceans haven’t experienced for more than 20 million years.
