New IEA Report Calls for Energy Revolution to Avoid Climate Catastrophe
The International Energy Agency (IEA) released today a major new report warning that nothing short of an energy sector revolution is required to protect the world from runaway climate change and a global temperature rise beyond two degrees Celsius.
In what is the IEA’s most urgent call for climate action yet, the World Energy Outlook Special Report 2013: Redrawing the Energy Climate Map advocates a “reorientation of an energy system currently dominated by fossil fuels,” and proposes near-term action to clean up the power sector and halt the increase of global emissions by 2020.
It also calls for “transformational” change in energy generation worldwide in the longer term.
IEA Executive Director Maria van der Hoeven said:
Climate change has quite frankly slipped to the back burner of policy priorities. But the problem is not going away—quite the opposite.
This WEO [World Energy Outlook] Special Report is a timely reminder that climate change must remain a permanent and prominent item on the policy agenda. It seeks to outline the intensive action which we need to start implementing today, without waiting to 2020 or later for a global agreement to take effect.
Compared to 2011, energy-related carbon dioxide emissions in 2012 have increased by 1.4 percent.
A new global agreement aimed at meeting this target will not emerge before 2015 and is not likely to be implemented before 2020.
Meanwhile, the world is drifting further towards dangerous levels of average temperature rise and runaway climate change; the IEA projects an increase of 3.6 to 5.3 degrees Celsius by the end of the century. Scientists warn this level of warming could threaten civilization as we know it.
In its "4-for-2 degrees Celsius" scenario, the report proposes four near-term “pragmatic and achievable” measures to put the world on track to limiting warming to safer levels and could reduce emissions by eight percent on levels otherwise expected by 2020 without harming economic growth.
Targeted energy efficiency measures in buildings, industry and transport would account for nearly half of these savings by 2020 while limiting the construction and use of the least-efficient coal-fired power plants could deliver another 20 percent of these savings—while helping to curb local air pollution.
The report estimated renewable energy generation would increase from around 20 percent to 27 percent over the same period to fill the void created.
Halving methane releases from flaring in the oil and gas industry could provide another 18 percent of the savings and implementing a partial phase of out fossil fuel consumption subsidies would account for 12 percent, according to the report.
The IEA also makes the economic case for avoiding a looming 2017 lock-in for long-term warming above 2ºC. While delaying climate action across the entire energy system till 2020 would save $1.5 trillion, the report estimates that an additional $5 trillion will be needed in low-carbon investment after this date.
Fossil fuel power plants have long life cycles and are therefore exposed to serious risks in a carbon-constrained world, facing early and costly retirement or retrofitting, or even becoming “stranded assets.”
In a report last year, the IEA warned that—to stay below two degrees Celsius—about two-thirds of proven global fossil fuel reserves have to stay in the ground. Yet companies spend vast amounts not only digging up known fossil fuel reserves but by looking for and developing new fossil fuel reserves.
A recent report from the Carbon Tracker Initiative found that the financial industry invested $674 billion in such projects last year alone, and warned that $6 trillion could be pumped into a "carbon bubble" over the next decade.
In response to this dire outlook for carbon-intensive utilities, the IEA promotes a strong global carbon market and carbon capture and storage (CCS) technologies as possible ways to avoid problems and to create a role for fossil fuels in the future energy mix of a carbon-constrained world.
However, in the same report the IEA also warns that the use of CCS “remains distant” as the technology has yet to be deployed at scale, and it could still be many years before the power sector could rely on it, if full-scale deployment ever becomes a reality.
While generally welcoming the IEA’s call to action, environmental groups have upped the stakes.
Samantha Smith, leader of the World Wildlife Fund (WWF) Global Climate & Energy Initiative said:
This is a welcome intervention by the IEA, particularly the focus on energy efficiency standards for lighting, cars and appliances as well as cutting methane losses in oil and gas production. Unfortunately, the other policies are incomplete, not ambitious enough or regionally biased. With the world on track for catastrophic levels of global warming, as the IEA says, these stop-gap proposals simply don’t go far enough.
Building on IEA arguments they argue that the IEA should set a target to cut emissions from coal power 20 percent by 2020—targeting all power stations.
They also call for deeper cuts in fossil fuel subsidies, phasing out both consumption subsidies and production subsidies—those providing incentive for exploring for new reserves—in both developed and developing countries.
According to the IEA, $523 billion was spent globally in 2011—up 30 percent from 2010 and huge in comparison to the $88 billion spent on subsidising clean renewables.
WWF says governments should instead use taxpayer money to boost renewables and fight energy poverty.

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.
Where Does the Deficiency Begin?<p>Nobody knows exactly how much vitamin D a person actually needs. The question of when a deficiency starts is correspondingly controversial. However, vitamin D is becoming increasingly popular.Not only is the pseudo-scientific literature on the "sun vitamin" experiencing an upswing, but the number of published studies has also increased enormously in recent years. For example, in 2019 <a href="https://academic.oup.com/edrv/article/40/4/1109/5126915" target="_blank">a study found that</a> Vitamin D is responsible for keeping the skeleton functional and is associated with cardiovascular diseases, type 2 diabetes and various types of cancer. <br></p>
An All-Rounder<p>Vitamin D levels in the body rise and fall according to sun exposure. If sufficient UV rays reach the skin, the body is able to produce the vitamin itself. However, the human body only derives an estimated 10 to 20 percent of its daily requirement from food.</p><p>The vitamin D that we synthesize from sunlight or food is not biologically active at first. Before the kidneys can produce the biologically active form of the vitamin, known as calcitriol, and release it into the blood, some metabolic processes must take place beforehand.</p><p>In addition, many organs have receptors to which the precursor of calcitriol binds. Further, this substance is also present in blood.</p><p>From this precursor, the organs then produce calcitriol themselves, which the body then uses for countless other processes in the body. This form of vitamin D thus regulates insulin secretion, inhibits tumor growth, and promotes the formation of red blood cells as well as the survival and activity of macrophages, which are important for the <a href="https://www.mdpi.com/2072-6643/5/7/2502/htm" target="_blank">immune system.</a></p>
Low Vitamin D, Severe COVID-19 Disease?<p>A research study carried out <a href="https://www.sciencedirect.com/science/article/pii/S2352364620300067?via%3Dihub" target="_blank">at the University of Hohenheim</a> has now established a link between vitamin D deficiency, certain previous diseases, and severe cases of COVID-19.</p><p>According to the study, "there is a lot of evidence that several non-communicable diseases (high blood pressure, diabetes, cardiovascular diseases, metabolic syndrome) are associated with low vitamin D plasma levels. These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe COVID-19 events."</p><p>"This statement is completely correct," said Martin Fassnacht, head of endocrinology at the University Hospital of Würzburg. However, he qualifies that it is a pure association, "i.e. a mere observation that these events occur together.</p><p>Dr. Fassnacht is very critical of the hype surrounding vitamin D, but not because he denies the vitamin serves important functions. However, studies on humans have not been able to show that vitamin D has the healing powers many often propagate.</p><p>Fassnacht says, "If you take a closer look, the hopes that the administration of vitamin D has a healing effect have not been confirmed so far."</p>
Association Versus Intervention Studies<p>Many studies on the vitamin are association or observational studies. "By definition, these studies cannot prove the causal relationship, but only point to mere correlations," said Fassnacht. The physician tries to illustrate this with an example:</p><p>"Imagine two groups of 80-year-olds. One group is spry, active and does sports. If you compare them with another group living in nursing homes, the difference in vitamin D levels will be dramatic. Life expectancy would also be extremely different."</p><p>But to try to explain the difference in fitness by vitamin D status alone is far too simplistic. "Vitamin D levels are a good measure of how sick someone is. But not more," says Fassnacht. </p><p>According to Fassnacht, none of the intervention studies carried out to date -- that specifically examined the effect of vitamin D on various diseases -- has been able to confirm the previous association and laboratory studies or the presumed positive effect of vitamin D.</p>
Further Research Is Needed<p>"If a coronavirus infection is suspected, it is therefore absolutely necessary to check the vitamin D status and quickly correct any possible deficit," said the recommendation of the paper published by the University of Hohenheim.</p><p>"Studies are underway to see whether vitamin D helps in COVID-19 infection, but I personally do not believe that this is really the case," says endocrinologist Fassnacht. Nevertheless, he says it is of course useful to carry out these studies.<br></p><p>"I don't want to rule out that there are actually subgroups of people who benefit from an additional vitamin D dose," he says. After all, this has been proven to be the case with a severe deficit.</p><p>In view of the study situation, Fassnacht does not think much of preventive, nationwide vitamin D substitutes. "My belief that the vitamin helps somewhere is very low. But, of course, I can be wrong."</p>
