Why Carbon Matters

The bulk of humanity’s energy needs are currently met through the combustion of fossil fuels like coal, oil, and natural gas. About 60% of global electricity generation relies upon fossil fuels (for Australia this %age is even high upto about 95%) to generate the heat needed to power steam-driven turbines. Burning these fuels results in the production of carbon dioxide (CO2) – the primary heat-trapping, “greenhouse gas” responsible for global warming.

The greenhouse effect

The term ‘greenhouse effect’ was coined to describe the way some gases in the atmosphere (such as carbon dioxide, nitrous oxide, and methane) trap some of the light energy from the sun after it is reflected from the Earth's surface, and  before it can escape out into space, so warming our atmosphere. This is a natural process that has been happening for billions of years, and without it the Earth would be about 33°C colder – too cold for us to live on. Now, however, human influence has upset the natural balance of carbon dioxide and other greenhouse gases and too much of the sun’s energy is being trapped, causing average temperatures to rise.
Over the past two centuries, mankind has increased the concentration of CO2 in the atmosphere from 280 to more than 380 parts per million volume, and it is growing faster every day. The atmospheric concentration of CO2 has not been this high for at least the past 650,000 years. As the concentration of CO2 has risen, so has the average temperature of the planet.

High levels of CO2
Human greenhouse gas emissions have gone from practically nothing to tens of billions of tons per year since the start of the industrial revolution. At present, over 30 billion tonnes of carbon dioxide (CO2) is emitted globally each year by burning fossil fuels, and another seven billion tonnes by changes of land use, mainly deforestation.

Rising temperatures and the greenhouse effect

The scientific community agrees – climate change is happening and human activity is almost certainly the cause. In the last 100 years the Earth has warmed by 1.3°F ( 0.74°C)--and by 0.4°C since the 1970s only, meaning that global sea levels have gone up, glaciers and sea ice has melted, floods and droughts are on the increase, and heatwaves are worse. Moreover, we are committed to further unavoidable climate change from this past rise in temperature, including further sea level rises for centuries to come. Data trends shows that if we continue to emit carbon without restraint, temperatures are expected to rise by an additional 6°F (3.4°C) by the end of this century.

Climate change causes extreme weather and temperature rises
Climate change of that magnitude would likely have serious consequences for life on Earth. Sea level rise, droughts, floods, intense storms, forest fires, water scarcity, and cardiorespiratory and tropical diseases would be exacerbated. Agricultural systems would be stressed – possibly decimated in some parts of the world. A conservative estimate suggests that 30% of all species are at risk of extinction given current trends. It would be the greatest extinction of life on Earth since the K-T extinction event that destroyed the dinosaurs 65 million years ago. No one can imagine, never mind predict, the ecological consequences of such a radical loss of life.

The global effects of climate change
Around the world, climate change would cause greater risks from rising sea levels, flooding, droughts, food shortages, diseases, water shortages and loss of tropical forests.
Southern Europe and the Mediterranean Basin are the most vulnerable regions in Europe, and mountain areas (in particular the Alps), islands, coastal regions and densely populated floodplains are facing serious consequences.
Outside Europe, developing countries (especially small island states) will be at great risk. The danger of flooding will become increasingly severe for low-lying countries like Egypt, Bangladesh and Thailand.
According to the Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC) in 2007, we could expect to see continued melting of ice caps, glaciers and sea ice, significant changes in rainfall patterns and possibly more intense tropical cyclones such as hurricanes.
Flooding will contaminate drinking water, expose people to toxic pollutants and make the delivery of health and social services more difficult. Droughts will increase the risk of water shortages. Food and water shortages could lead to conflict and migration.

There is also the risk that continued warming will push the planet past critical thresholds or “tipping points” – like the large-scale melting of polar ice, the thawing of tundra or methane clathrates, the collapse of the Amazon rainforest, or the warming and acidification of the oceans – that will make further climate change inescapable and irreversible. The history of Earth suggests that such positive feedback loops in the climate system are powerful and often severe. If our greenhouse gas emissions succeed in pushing the climate past the point of no return, we are unlikely to realize it until it is too late to avoid the consequences.
Despite mounting evidence of the dangers posed by climate change, efforts to limit carbon emissions remain insufficient, ineffective, and, in most countries, non-existent. If the world is to avert the worst consequences of an altered climate, the status quo must change quickly. Given current trends and the best available scientific evidence, mankind probably needs to reduce total CO2 emissions by at least 80% by 2050. Yet each day emissions continue to grow.
Even in the absence of prompt action on the part of governments, we are joining hands with millions of increasingly climate-conscious citizens who can promote low-carbon alternatives by changing the ways they purchase, invest, vote, think, and live. All you need to act is provide timely, accurate, publicly-available information about the choices you face. It’s time to take matters into your own hands.
Truly progressive communities are those in which we are as optimistic about our collective progress as we are about our individual ambition and where individuals are not allowed to waste resources that others in our community need but cannot afford.
Whether it’s driving, flying or turning on the air conditioner, our daily activities produce carbon dioxide (CO2) emissions. Changing lifestyle and attitude towards luxurious life is an easy and inexpensive way to balance out, or “offset” the environmental consequences produced by our energy-intensive lifestyles. You may also support different other programs that reduce or prevent the release of CO2 emissions from driving, flying, etc.

Going green isn’t black and white.
There are several actions you can take today to move toward a greener, more environmentally friendly lifestyle.  At WATEEN, we offers online energy-saving tips and tools to help you analyze your energy usage and find ways to conserve. Being efficient doesn’t stop with energy. Learn more about how you can make your overall lifestyle more efficient.

Cleaner, greener technologies
Cleaner technologies and renewable energy sources including solar, wind, biomass and water are providing new opportunities for reducing emissions and our dependence on depleting oil sources. These low-to-zero emission technologies will play an increasingly larger role in meeting the nation’s future energy demand.

Reviewing Lifestyles-Suggestions
We are also developing  facilities for environmental education where a broad range of generations, from children to adults, can learn about environmental problems, especially global environmental problems.  At schools, students will be given practical training for environmental protection and the creation of a better environment. To provide this training, environmental education and energy education must be improved by providing educators workshops, improving the leadership ability of educators, and improving teaching materials relating to energy and the environment.

About a Low Carbon Economy
There is an urgent need to transition to a low carbon economy to address the global challenges of diminishing fossil fuel reserves, climate change, environmental management and finite natural resources serving an expanding world population.
All or any of these reasons mean that urgent action is required to transition to solutions which minimise environmental impact and are sustainable. Failure to deliver such action will have catastrophic consequences for mankind, both economically and physically.

Get Involved
The opportunity to act to maximise the positive economic benefits as well as minimising the consequences of inaction is here today.
Many say that the transition to a low carbon economy offers the greatest economic opportunities ever known. At the start of the information revolution, few would have guessed at just how widespread and profound the effect would be on society: today we can barely imagine life without modern information technology. Companies like Google, Yahoo! and Amazon are some of the most successful companies in the world.
We are now at the start of the low carbon revolution and those that have started on their low carbon journey already are seeing benefits such as new markets and customers, improved triple bottom line (economic, social and environmental performance) and reduced bills and risks.

In a Low Carbon Economy, main emphasize will be on the following policies

• All waste should be minimised - reduce, reuse, recycle
• Energy should be produced using low carbon energy sources & methods - renewable & alternative energy sources, fuels & sequestration
• All resources (in particular energy) should be used efficiently - more efficient energy conversion devices, combined heat & power
• Wherever practical local needs should be served by local production - food, materials, energy
• There is high awareness and compliance with environmental and social responsibility initiatives - industry, commerce and individuals
