Global Warming vs Climate Change

The terms- global warming and climate change are usually misinterpreted in the media while getting discussed; however, these remain distinct to each other, a fact which is often ignored.

Both of these terms refer to two different physical phenomenons.

Global warming is basically a long term trend, erupting due to the constant global temperature rise owing to the greenhouse gases usually from the fossil fuel burning.

Whereas climate change is all about the changes seen in the global climate, which is actually the outcome of increasing average global temperature.

Though both of these physical phenomenons are usually related to each other, yet they remain two distinct things. Let’s look at the comparison between the two.

Both Terms Have Been in Use for a Long Time

Many people argue that the term global warming was used much before and climate change came into picture in the recent years.

But the fact is it is simply a false claim.

For instance, if you look at the seminal climate science project carried out by Gilbert Plass in the year 1956, his own study was seen using this term wherein he was seen discussing climate sensitivity. Similar in the year 1971 when different researchers like Gast and Barrett were seen discussing this issue using the very same terminology, whereas in 1977 the most popular journal Climate Change started its publication, which is seen till today.

The popular agency IPCC taking care of this subject deals more with climate change than global warming.

In this way, you can find a number of examples that vouch for the fact that both these terms have been in use for many decades and cannot be termed as a newly introduced trend by researchers.

Global Warming

If you look closer to global warming, it could be defined as the increasing warming up of the Earth owing to the rise of greenhouse gases especially the ones coming from the fossil fuels burning events. The increasing warming of the earth can be gauged in the Earth’s ocean and atmosphere.

You can find good evidence for global warming, which includes retreating ice caps, increased habitat reductions for different animals, dry lakes, shifts seen in weather, global temperature rise, seal level rise, coral bleaching, etc. Global warming could be called as a human induced global temperatures rise.

Climate Change

If you look at climate change, it is termed as the natural changes seen owing to the global temperature rise over the years of time.

Speaking more specifically, the change found over the earth’s energy budget could give the result in terms of both increase and decrease in the global temperatures.

The climate is always seen changing, which is an important fact that people usually ignore when they are seen talking about this issue.The climate change is seen often occurring over the planet earth for a number of reasons. These include things like volcanic eruptions, Milankovitch cycle, ocean circulation changes, natural variance, tectonic activity and albedo.

Interchanging the Term is Basically the Mincing of Words

In the media, you often would see the term global warming being interchanged with climate change or vice versa. This is mincing words.

And if you club both these terms, you simply end up getting global warming as a climate change, which is induced by the human beings. There are people who doubt or go against global warming often termed as anti warming activists are seen mincing the two terms simply by detracting both the issues.

However, bringing out a standard definition is simply impossible since the fact is climate change always occurred and is going to be there in the future as well, while global warming is a theoretical concept.

However, this helps the experts to definition of this particular theory. This is the very juncture where you will find a number of non scientists going wrong. Theories are basically scientific evidences and proofs, which are collected all these years and often get accepted by the people as a suitable explanation to these evidences or proofs.

Theories are very much different than the scientific laws and hypotheses.

Hypothesis could be defined as an intelligent guesswork, which is often based on knowledge and information; however, this requires a consistent testing for your further development. At the same time the laws are basically scientific facts, which are very much virtually incontrovertible. For example, if you throw anything at the upper direction, it is bound to come down due to gravity, which is basically a law of science.

Final Word

Though both terms are seen interchanging, these issues remain the most contagious problems of the modern times. Global warming and climate change have now become a matter of concern basically due to the industrialization taking place in the world, which has wrecked havoc over this planet. The amount of disruption caused to the ecosystem due to these issues is certainly going to harm the animals, trees and even human beings.

Did the Australia Carbon Tax Initiative Really Reduce Carbon Emissions?

Generally, plants and trees need carbon to survive in contrast to animals and humans who need oxygen to live. However, the increasing amount of carbon in the atmosphere has led to changes to the environment, such as a shift in weather pattern and the rise of atmospheric temperature all over the world. So, to bring back balance to Earth’s atmosphere, governments began to implement green initiatives, including carbon tax, designed to reduce carbon emissions caused by burning gas, coal or crude oil from manufacturing plants and other industrial sites.

A Significant Drop in Carbon Emissions Index

The Australian government introduced its carbon tax in July 2012 after years of debate. According to BBC News, around 300 firms were levied at $23 Australian dollars per tonne of greenhouse gases they create. When the country’s top industries include mining, steel manufacturing, and energy generation, this legislation can be an alarming threat. The opposition branded it as “toxic tax” that will cost people their jobs and increase the cost of living in the country.

However, after nearly four months since its implementation, reports from ABC News and other local media revealed positive results. Victoria alone has had a 8.7 percent reduction in its carbon emissions since July. All over the country, the fall in record emissions reached down to 7.6 percent, according to a report from the Australian Energy Market Operator (AEMO). Hopefully, this trend continues until the year 2020 and meets the government’s goal of reducing carbon levels by five percent or less in all regions.

But, what does this mean to consumers and businesses? Will the Australia carbon tax lower power rates, supply enough energy for a growing population, and still attract investors to the mining and energy sector? Nobody knows for sure how far and wide the benefits of the levy would go ten years or twenty years from now. One thing’s certain though: consumers and small business owners end up reaping the benefits of getting energy from abundant sources.

Carbon Tax Led to a Surge in Power Costs?

Of course, it’s too early to predict the downfall of the energy and mining industries of Australia as result of the levy. Naturally, an increase in power rates began almost immediately after implementation. Energy firms had to cover the cost of paying taxes for every tonne of pollutants they release into the atmosphere. On one hand, these discouraging power rates shifted public attention to more efficient technologies, such as hydroelectric turbines and solar panels. Although the demand for renewable energy hasn’t begun to surge yet nationwide, the huge investments of companies and their high production expenses has nudged clean energy prices a bit closer to traditional rates.

The AEMO report also admits that other possible factors may have contributed to the decrease in the Carbon Emissions Intensity Index (CEII) during the months of June through August. Before the carbon tax, floodwaters in Gippsland, Victoria stopped operations for the Yallourn power plants, which supply most of the energy to that region. They had to go offline for emergency cleanup and repairs. These power generators run on coal fuel and their temporary absence may have led to a significant decrease in carbon levels. In short, the policy has definitely been successful in curbing the atmospheric levels of carbon over large regions in Australia, but there were negative effects from paying too much taxes too soon and to the energy sector’s mad scramble to provide more clean energy options to consumers.

Thermal Imaging at Home: To Save Your Planet and Money

The innovation of ‘Thermal Imaging’ has impressively changed the pre-learned concepts and theories of people.

‘Thermal Imaging’ with the help of infrared radiations, helps us to notice the density differences and temperature fluctuations in any tangible thing around us. Till today, this method has been generally used to detect biological upsets in delicate body organs and sometimes by property owners to track out the hidden causes of safety issues within the house. The temperature fluctuations or the structure tempering detected by a thermal imaging camera are not possible to be noticed with bare eyes.

Now assuming that seventy percent of the world population understands the catastrophic effects that global warming is having on the earth, we have come up with diverse ways to seek out solutions to this problem. And the solution is not just about using air, water and sun for primary energy needs, it embodies every particular aspect of the way we live in and behave. Here we introduce the very new concept of thermal imaging.

But the new benefit that is credited to this technology is being beneficial to the environment. Of course, on close scrutiny, we find that thermal imaging points out sources of abnormal heat loss in a particular area that is different from its surrounding area. We all know that heat radiated out from constructions is a potent source of global warming. Any unwanted source of heat due to an unseen leakage could be an additional cause that would aggravate the problem although with utter paucity.

Secondly, the technology is a potent application for those who wish to buy themselves a piece of livable property. Remember, thermal imaging cameras help to detect flaws which go unseen by human eyesight? So now, before you start working on your dream house, you have all the resources to make sure that the same does not become a liability to your pocket in the future. Any kind of construction mishap could not only need to be repaired urgently in the future, thus adding to your costs, it could also pose to be a threat to the safety of the residents of the house. For example, a weak insulation in the wall could lead to short circuit. It would remain unnoticed, but it cannot be ignored via a thermal imaging camera.

Thirdly, thermal imaging facilities provided by many companies, keeps the user informed about the leakages in the building structure. Still, if you have not switched to the advance thermal imaging facility, then it is the right time to do so. It is always better to bear a few additional costs rather than facing innumerable difficulties and repeated expenditures in the future. This will result in long term gain in terms of peaceful and hassle free life-style. Moreover, it will also contribute a lot in sustaining the atmosphere and the planet resistant with many global warming related issues.

Earth Hour Exceeds Target Of 1,000 Cities

VOTE EARTHLast year I mentioned that this year’s Earth Hour will be the biggest to date, but it’s also turning out to be even bigger than the organizers expected. 

No less than 1,539 cities and towns in 80 countries will participate in this year’s Earth Hour 2009. 

This number, which will almost certainly grow over the next eleven days, exceeds the organizers’ target of 1,000 cities. 

With more and more cities and towns signing up every day, the event organizers say that the success of Earth Hour 2009 is limited only by the will of the global community to want a say in the future of their planet.

“Earth Hour is an opportunity for the global community to speak in one voice on the issue of climate change, while at the same time coming together in celebration of the one thing every single person on the planet has in common – the planet” said Earth Hour Executive Director, Mr Andy Ridley.

“Whether it’s joining your community in a town square to watch the city lights go dark or hosting a lights out party in your own home, I encourage everybody across the world to be a part of this historic occasion. Turn off your lights, celebrate the planet, enjoy the moment and cast your vote for Earth,” he added.

With increased involvement from populous countries such as China, it is hoped that Earth Hour 2009 will be observed by over 100 million people around the world.

Earth Hour 2009 to be Much Bigger than 2008

Earth Hour 2009 will be at least 3 times bigger than 2008 with more than 76 cities officially participating. These before/after photos were taken during Earth Hour 2007 in Sydney. Photo: madradish.

Earth Hour 2009 stands to be the biggest Earth Hour to date. Last year, 26 cities officially participated in Earth Hour. The current count for 2009 is almost 3 times that figure – and we’re still more than 3 months away from the event.

Furthermore, organizers anticipate that over 1 billion people will take part in 2009 – up from 50 million in 2008. This is largely due to China’s involvement in 2009, where populous cities such as Beijing and Shanghai will participate

The official number of cities to participate in Earth Hour 2009 currently stands at 76 cities.

The 12 day United Nations Climate Change Conference began in Poznań, Poland yesterday.

Delegates from 190 countries have gathered to try to agree on a treaty to be signed next December in Copenhagen.

“The protection of the climate requires global solidarity,” said Donald Tusk, Poland’s Prime Minister, as he addressed the delegates.

“All of us must show maximum understanding with each other, and must show patience with each other,” he continued “but this patience must be have its own horizon – a common goal.”

Shared Vision

Although the full text of a treaty won’t be agreed on at the conference, it is important that the member nations agree on a shared vision.

“What is the shared vision? It’s two 2 things,” says Brice Lalonde head of the French delegation.

“One is having a goal of reduction of emissions and agreeing on that goal, and the other is how do we have a cooperation of all the nations of the world?”

…Or Not

But the United States has a different view.

Regarding the possibility of agreeing on a fixed 2020 target for reducing greenhouse gas emissions, the US was noncommittal.

“I don’t think many parties are ready to sign onto any range at this time,” says Harlan Watson, head of the United States delegation.

“My own opinion is that that’s going to occur in the end game” in Copenhagen.

“We’ve seen in past discussions of this that a number of parties aren’t prepared to agree to a long-term goal until other parties are coming forward with a 2020 or a near-term goal, and a number of parties, including the United states, are not willing to come forward with that yet.”

Message From Environmentalists

Environmental groups are urging the UN member nations to reduce their dependency on coal. Coal is the single greatest threat to our climate  – coal burning contributes more to climate change than any other fossil fuel.

With coal-fired power stations producing 11 billion tonnes of carbon dioxide each year, environmental groups are pushing for the widespread adoption of renewable energy sources, such as solar and wind.

Furthermore, green groups are pleading with governments to stop the approval of new coal plants. A coal plant built today will emit CO2 pollution for at least the next 40 years.

As the Climate Change Conference gets underway, Greenpeace has set up a Climate Rescue Station on the edge of a coal mine in Poland to highlight the true cost of coal.

Greenpeace wants to see the following outcome from this year’s climate change conference:

  • A “climate vision” that will address what the science requires: global emissions peaking by 2015
  • A draft negotiating text on the table and a detailed workplan to get this completed by Copenhagen in December 2009
  • Developed countries to agree greenhouse gas emission reduction targets at the upper end of 25-40%, as identified by the IPCC

How You Can Help

This year the world is watching the UN negotiations and demanding that governments make good on their promise to come up with an action plan in Copenhagen next year.

You can help by uploading your photo to show that you are watching the UN carefully this year. Uploaded photos will be projected at this year’s UN meeting. 

About the United Nations Framework on Climate Change 

The United Nations Framework on Climate Change (UNFCCC) is a treaty by most of the world’s nations to consider what can be done to reduce global warming and to cope with whatever temperature increases are inevitable.

Initiated in 1992,  the treaty set no mandatory limits on greenhouse gas emissions for individual nations and contained no enforcement provisions; it is therefore considered legally non-binding. Instead, the UNFCCC treaty includes provisions for updates – called “protocols” – that would set mandatory emission limits.

The principal update (or protocol) is the Kyoto Protocol, which has become much better known than the UNFCCC itself. The Kyoto Protocol has more powerful (and more legally binding) measures than the UNFCCC.

Marine Reserves Do Not Guard Against Climate Change

Marine reserves currently provide coral reefs with little protection against global issues such as climate change and disease outbreaks.

Marine reserves currently provide coral reefs with little protection against global issues such as climate change and disease outbreaks.

Marine reserves, while effective at protecting coral reefs against local issues, are not protecting them against global issues such as climate change, according to Associate Professor John Bruno from the University of North Carolina.

Professor Bruno presented his findings to the Ecological Society of Australia’s annual conference at the University of Sydney.

18 Years of Data

In a speech entitled Climate change and coral reef resilience: are we expecting too much from marine reserves?, professor Bruno and former graduate student Elizabeth Selig compared 18 years worth of data collected from 8,540 coral reefs in the Indian, Caribbean and Pacific regions between 1987 and 2005. 

They found that, while marine reserves are important for protecting fish populations, maintaining coral reef food webs and protecting against anchor damage, they are unlikely to prevent coral loss due to increased sea temperatures.

“We found that while coral loss was reduced in marine reserves, the rate of coral decline with warmer temperatures was just the same in marine reserves as in highly fished areas,” professor Bruno explained.

Largest Threat

Bruno believes that regional and global issues are the largest threats to marine reserves. 

“The biggest stresses put on coral reefs are ocean warming and disease outbreaks,” he says. “These stresses are regional and global in scale and local protection through marine reserves is unlikely to help these reefs resist such changes.”

Older Reserves Are More Resilient

Although marine reserves don’t directly guard against regional and global issues, professor Bruno did find that older reserves are in a better position to protect against coral loss than younger reserves.

“We don’t know the reason for this result, although we can speculate that it could be due to longer-term marine reserves being better managed or established,” he says.

Future Protection

Bruno believes that we need to think long term and establish marine reserves that can protect coral reefs from unknown future threats.

“Restoring and protecting corals from climate change requires urgent implementation of regional and global strategies to deal with the root causes of climate change, including reducing carbon emissions.”

Is Coal Really That Cheap? Greenpeace Reveals The True Cost Of Coal

As environmentalists push for “green” energy, the coal industry continues to emphasize the fact that coal is cheaper than its greener alternatives. 

But is coal really as cheap as we think it is?

Greenpeace has released a report that reveals the true cost that coal is having on the world at large.

Entitled The True Cost Of Coal: How people and the planet are paying the price for the world’s dirtiest fuel, the report shows that coal is costing the world around €360 billion per year.

Over the next ten years this would translate into €3.6 trillion – roughly $US4.6 trillion. 

The Hidden Costs

In calculating the figure, Greenpeace looked at the external costs of coal, such as costs arising from mining accidents, acid rain, and more.

The report says:

Traditionally considered the cheapest fuel around, the market price for coal ignores its most significant impacts. These so-called “external costs” manifests themselves as damages such as respiratory diseases, mining accidents, acid rain, smog pollution, reduced agricultural yields and climate change.

Greenpeace explains that the the harm caused by mining and burning coal is not reflected in its price per tonne or its costs for a kWh of electricity, but the world at large is nevertheless paying for it.

Coal’s Impact On Climate Change

The report also explains that coal burning contributes more to climate change than any other fossil fuel, and that coal-fired power stations produce 11 billion tonnes of carbon dioxide each year. 

Greenpeace emphasizes that our decisions regarding coal is not something we should take lightly:

As the single largest source of CO2 emissions, the manner in which we deal with coal in the coming years will determine whether we can respond adequately to the climate crisis.

And, our decisions of today, will have an ongoing impact for years to come:

A coal plant built today will emit CO2 pollution for at least the next 40 years.

Dirty Coal vs Clean Coal?

And Greenpeace is not impressed by so called “clean coal”, where carbon from the burning coal is captured and stored underground.

Greenpeace says that, even if it were a feasible option, there isn’t enough time to deploy Carbon Capture and Storage (CCS) plants.

The earliest possibility for deployment of CCS at a useful scale is not expected until at least 2030, while global greenhouse gas emissions must start falling after 2015 to avoid the worst impacts of climate change 

Greenpeace believes that CCS is providing an unwelcome distraction in the discussion on reducing greenhouse gas emissions:

Those peddling technological fixes – such as carbon capture and storage which claims to make coal clean and safe for the climate – create a dangerous distraction as the world seeks truly sustainable solutions that will reduce emissions and protect our climate. It is only by quitting coal and increasing energy efficiency and production of renewable energy that we will prevent catastrophic climate change. 

Coal Must Be Phased Out

The strong message in the report is that coal must be phased out, and proposed coal-fired power stations must not go ahead.

Instead, Greenpeace emphasizes that renewable energy and energy efficiency must be the way forward:

Given the availability of alternatives such as renewable energy and energy efficiency, which can meet our energy needs in a safe and climate-friendly way, there is no need to continue relying on coal. We must reduce our dependence on this dirty fuel and abandon plans to build new coal-fired power stations. 

So, given the true cost of coal, the report makes the argument for renewable energy even more compelling.
