With today’s announcement of a national climate action plan, President Obama is pushing forward to tackle the urgent challenge of climate change. This is the most comprehensive climate plan by a U.S. president to date. If fully and swiftly implemented, the Obama Administration can truly reset the climate agenda for this country.
The plan looks to reduce harmful greenhouse gas emissions in a comprehensive way and takes on the question of how to protect the country from the devastating climate-related impacts we are already seeing today. With a clear, national strategy in place—and concrete steps to implement it—the administration can protect people at home and encourage greater ambition internationally.
Importantly, the president is recommitting the U.S. to meet its target of reducing greenhouse gas emissions by 17 percent below 2005 levels by 2020. World Resources Institute’s (WRI) recent analysis demonstrates that meeting this target is achievable, but requires ambitious action across many sectors of the economy. WRI identifies four areas with the greatest opportunity for emissions reductions—power plants, energy efficiency, hydrofluorocarbons (HFCs) and methane—which are all specifically included in the plan.
The plan is also notable for addressing climate impacts and encouraging increased international engagement. Together, these steps can help the U.S. reclaim lost ground on climate change. While there are many details to be worked out, this plan is a welcome step to putting the U.S. on a pathway to a safer future.
Reducing Carbon Pollution from Power Plants
First off, the president’s plan commits the U.S. to address carbon pollution in existing power plants. Power plants currently represent one-third of all U.S. greenhouse gas emissions, the largest source of carbon dioxide (CO2) pollution in the U.S. The president also directs the U.S. Environmental Protection Agency (EPA) to move quickly to finalize the proposed CO2 pollution standards for new power plants.
These actions will be important for protecting people’s health and the planet—and WRI analysis finds that they can be implemented in a way that is flexible and cost effective. It will be important for the EPA to act with a sense of urgency in order to meet the U.S. emissions target. Just as important as the time frame for finalizing these standards is their stringency. Without sufficient ambition, the U.S. will not be able to achieve the reductions it needs by 2020 and in the years beyond.
Increasing Renewable Energy and Energy Efficiency
The additional actions and goals that the President has laid out in the plan for renewable energy and efficiency will be important in allowing stringent power plant standards to be achieved in a cost-effective manner.
On energy efficiency, the president announced a new goal to reduce CO2 pollution by a total of 3 billion metric tons through 2030 through new and existing efficiency standards for appliances and federal buildings. This would be a significant reduction, the equivalent of eliminating nearly two years’ worth of emissions from coal power plants.
Energy efficiency is one of the most cost-effective ways to reduce emissions, as more efficient equipment uses less energy and therefore saves consumers money. There are dozens of products that are excellent candidates for new and updated efficiency standards—some of which are awaiting approval—and many more ways to capture this low-hanging fruit in the residential, commercial and industrial sectors. A recent analysis finds that there are a total of six standards that are waiting for approval. Each additional month of delay on these costs consumers $200 million in lost savings and pumps an additional 3 million metric tons of CO2 into the atmosphere.
The plan also calls for doubling renewable energy in the U.S. by 2020 and opening public lands for renewable energy development, to the tune of an additional 10 gigawatts of installed renewable capacity on those lands by 2020. This would be enough energy to power 2.6 million American homes.
This policy is a strong complement to the forthcoming emissions standards, as it could make compliance easier for utilities. The federal government owns roughly 28 percent of land in the U.S.; selectively opening up some public lands for clean energy projects should help ease siting concerns for utilities and project developers.
Reducing HFCs and Methane
The U.S. has been working for years to phase down the production and consumption of HFCs under the auspices of the Montreal Protocol. The recent agreement between the U.S. and China to work together toward this end is an important development in reducing emissions of this potent greenhouse gas. Both chemical and consumer product manufacturers support a planned global phasedown of HFC production and consumption. The plan also acknowledges that there is more the U.S. can and should be doing to eliminate its domestic emissions of HFCs under the Significant New Alternatives Policy Program. The plan also recognizes the importance of curbing emission of methane, another potent greenhouse gas. The President calls for development of an interagency methane strategy that improves data on methane emissions and identifies opportunities to reduce those emissions.
Preparing for Climate Impacts
Climate impacts are already happening globally. The U.S. is experiencing rising sea levels along our coasts, droughts in the Midwest, wildfires in Colorado and torrential rains in the Northeast. These impacts are taking a toll on our homes and our businesses. Drought impacts energy production and agriculture. Sea level rise threatens critical infrastructure and clean water supply. These risks are becoming a reality for people across the country.
In response, the plan aims to help Americans prepare for climate change impacts. Adapting to climate change will require striking the right balance between support and direction from the federal government and locally appropriate solutions. The plan focuses on reducing people’s vulnerability by identifying barriers and reforming policies. These actions can empower states and localities to tailor their adaptation actions to their location-specific climate challenges. It should also help create incentives for businesses to contribute to solutions. As the country rebuilds from Hurricane Sandy and other extreme weather events of recent years, it will be important to systematically learn what is working and what needs improvement.
International Climate Action
The president calls for greater engagement internationally—and this, too, is critically important. The U.S. can—and should—be a leader on this global challenge. Climate change will bring significant impacts that will affect our economy and our security.
The U.S. should re-engage in a purposeful and constructive way, working with the international community to rally toward an effective and ambitious international climate agreement by 2015. Cooperation on climate change—as signified by the recent announcement between the U.S. and China on HFCs—shows this is an area where collaboration is both necessary and possible. Enhanced U.S. action will catalyze other countries to come forward with a greater sense of ambition and urgency.
Moving Forward with Ambitious Climate Action
Today’s announcement marks a major milestone in the creation of a durable and far-ranging climate plan for the U.S. The details matter, of course, so we’ll be watching for more specific information about what the various agencies will do—and how quickly and strongly they take up this challenge.
This plan puts a marker in the ground that the Obama Administration is ready to take climate change seriously. It is a strong and broad approach—one that stakes new ground, but also builds on existing common-sense actions.
The plan makes clear the responsibility that we all have to take action for today’s communities and for future generations.

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>
