Scientists in Germany have constructed the world’s largest artificial sun in order research how to produce a developing renewable energy source.

Hydrogen is regarded as the renewable fuel of the future, mostly because it does not produce greenhouse gas emissions when burned. However, the gas isn’t found alone in the nature so scientists must split the molecules that make up water (H2O) in order to harness its power. Separating H20 molecules requires a great deal of energy; the German scientists hope to learn how to get that energy from sunlight.

The artificial sun, called “Synlight,” is comprised of 149 high-powered film projector spotlights and is able to generate 350 kilowatts. Bernard Hoffschmidt is research director at the German Aerospace Center, Synlight’s home. Hoffschmidt told the Guardian, “If you went in the room when it was switched on, you’d burn directly.”

The researchers will point all of the artificial sun’s energy at a single 8 by 8 inch spot where it will emit 10,000 times the amount of light that reaches Earth naturally from the sun. Using these strong rays, the scientists will be able to experiment with new ways of creating hydrogen fuel using energy from the sun.

In the short term, Synlight uses an incredible amount of energy: four hours of operation is equivalent to how much electricity a family of four would use in a year. Long term, the researchers anticipate it could help them learn how to use naturally occurring sunlight to produce hydrogen fuel without the use of any fossil fuels.

Hoffschmidt said, “We’d need billions of tons of hydrogen if we wanted to drive airplanes and cars on CO2-free fuel. Climate change is speeding up so we need to speed up innovation.”

Extreme weather reaches ‘uncharted territory’

Last year was a record-breaking year for climate change and not in a good way. Global temperatures set record highs for the third consecutive year and sea ice coverage worldwide shrunk by 4,000,000 square kilometers, that’s about the size of the European Union.

These extraordinary climate conditions led to extreme weather events all around the world. Among them, Hurricane Matthew in the Caribbean, the first category four storm to reach land since in 1963 and severe droughts in southern and eastern Africa. A recent report from the United Nations World Meteorological Organization found that extreme weather has carried over into 2017.

So far this winter, severe storms in the Atlantic Ocean have caused Arctic “heat waves” so that while ice cover in the region should be refreezing, many days it was close to melting. North Africa and the Arabian peninsula have seen colder than usual winter temperatures while parts of Canada and the U.S. have been much warmer than is typical.

David Carlson is the World Climate Research program director. He said, “Even without a strong El Niño in 2017, we are seeing other remarkable changes across the planet that are challenging the limits of our understanding of the climate system.”

In the month of February alone, nearly 12,000 warm temperature records were broken in the U.S.

Carlson added, “We are now in truly uncharted territory.”

Study finds majority of Americans want action on climate change

Researchers at Yale University have provided the most comprehensive look yet at U.S. public opinion and beliefs on climate change.

The study revealed that 70 percent of Americans agree that climate change is happening. Interestingly, while it is widely accepted in the scientific community that humans have caused climate change, only 53 percent of Americans believe this to be true, although 71 percent of the same individuals studied said that they trust what climate scientists say about climate change.

An overwhelming 82 percent of U.S. adults support the funding of renewable energy research projects. Despite this desire, former head of the Trump Department of Energy transition team, Mike McKenna, has publicly stated that the president’s administration is likely to cut funding for renewable energy and redirect funds to fossil fuel development.

Additionally, the Trump administration plans to eliminate President Obama’s plan to reduce carbon emission from the nation’s power plants by 30 percent before 2030. Meanwhile, the majority of citizens in every congressional district- that’s about 70 percent nationwide- support setting strict limits for carbon dioxide emission from power plants.

So why aren’t more Americans taking direct action on climate policy? Some say this has to do with the way humans prioritize risk. A report in the New York Times pointed out that we are only programmed to respond to threats that trigger our flight or fight response, that is, immediate threats. The safety risks and health effects of climate change often occur slowly over time, so we pay them less attention. For example, more than half of the study’s respondents believe that climate change is currently harming people in the U.S. In contrast, only 40 percent of citizens believe that climate change will ever harm them personally.

President Trump’s budget plan slashes EPA budget

President Donald Trump plans to cut U.S. Environmental Protection Agency funding by 31 percent according to his budget plan released Thursday.

In all, the proposed plan would cut $2.6 billion dollars from the agency and eliminate some 3,200 EPA jobs. Gina McCarthy was EPA administrator during the Obama administration. She said, “Literally and figuratively, this is a scorched earth budget that represents an all out assault on clean air, water, and land.”

While funding will be slashed for climate change research and Superfund site reclamation, some EPA programs will be eliminated all together. Among them are urban air quality improvement efforts, infrastructure projects on Native American reservations, energy efficiency improvement programs and water quality improvement work in the Great Lakes and Chesapeake Bay.

President Trump’s Office of Management and Budget Director Mick Mulvaney said, “Regarding the question as to climate change, I think the President was fairly straightforward. We’re not spending money on that anymore. We consider that to be a waste of your money to go out and do that.’ So that is a specific tie to his campaign.” More than 97 percent of climate scientists agree that climate warming over the last century are due to human activity, according to NASA.

In line with a recent report written by over 400 medical doctors, Bill Becker, executive director of the National Association of Clean Air Agencies said, “If such cuts are realized, many more people will die prematurely and get sick unnecessarily due to air, water and waste pollution.”

Other environmental activists and scientists were also quick to speak out against the proposed cuts. Fred Krupp is the director of the Environmental Defense Fund, he said, “This is an all-out assault on the health of our planet and the health and safety of the American people.” Krupp continued, “Cleaning up our air and protecting our waters are core American values. The ‘skinny budget’ threatens those values — and puts us all at risk.”

President Trump’s budget outline still must be approved by Congress and is expected to change. The Administration’s final budget will be released in May.

Top doctors say climate change harms human health

The Medical Society Consortium on Climate and Health released a report on Wednesday explaining the ways in which climate change harms the physical and mental health of people in the U.S.

The report, titled “Medical Alert! Climate Change is Impacting our Health” was written by medical doctors, including allergists, pediatricians, infectious-disease doctors, OB/GYNs and gerontologists from eleven health organizations.

Very few Americans, less than 32 percent, can name a specific way in which climate change harms human health. “Doctors in every part of our country see that climate change is making Americans sicker,” said Dr. Mona Sarfaty, the director of the new consortium.

The authors broke down the specific health effects of climate change in each region of the U.S. The doctors explain that three by-products of climate change will directly impact human health: air pollution, extreme heat and extreme weather events. Increased temperatures associated with climate change intensify smog, wildfires and pollen production, leading to poor air quality, the report said. “Poor air quality increases asthma and allergy attacks, and can lead to other illnesses, hospitalizations, and deaths,” the authors wrote.

Rising global temperatures cause more frequent, longer, and more extreme heat waves in many parts of the U.S. Excessive heat leads to heat-related illness, exacerbates some medical conditions, and can cause death due to heat-stroke and dehydration. The report read, “Anyone can be harmed by extreme heat, but some people face greater risk. For example, outdoor workers, student athletes, city dwellers, and people who lack air conditioning (or who lose it during an extended power outage) face greater risk because they are more exposed to extreme heat.”

The physicians pointed out that extreme weather events are also taking a toll on their patients. The increased frequency and severity of major storms, floods, and droughts can cause injury, displacement and death, the report read. These events often prevent residents from receiving proper medical care due to blocked roads, destroyed bridges and the like. Gastrointestinal illness and disease often follow the power outages associated with extreme weather events as well, according to the doctors.

Beyond these direct impacts, climate change also speeds up the spread of infectious diseases and has an insidious impact on humans’ mental health. With temperatures rising around the world, infectious disease vectors like ticks, mosquitoes and fleas can now survive in regions that were previously too cold for them. For example, “Ticks that carry Lyme disease have become more numerous in many areas and have expanded their range northward and westward,” the report said.

U.S. residents that have experienced increasingly common extreme weather events like foods, major storms, and droughts are likely to suffer mental health consequences including post-traumatic stress disorder (PTSD), depression, and anxiety. Anyone could experience these effects, but women, pregnant women, the elderly, children, and those with a preexisting mental health condition are most at risk.

The report concluded with a call to government leaders, asking them to address climate change in the name of human health. It read, “Doctors agree with climate scientists: the sooner we take action, the more harm we can prevent, and the more we can protect the health of all Americans.”

Intense summer heat to become more likely due to climate change

Southern Australia just endured its hottest summer ever recorded, and recent research found that the likelihood of more extreme summer weather is on the rise.

Following summer months where Sydney’s mean temperature remained 37 degrees Fahrenheit above average, Dr. Perkins-Kirkpatrick at the University of New South Wales in Sydney began to study the relationship between human-induced climate change and summer heat waves.

Along with other researchers at the World Weather Attribution, Perkins-Kirkpatrick concluded that climate change has made it 50 times more likely that New South Wales will experience another similarly scorching summer. Simply put, before 1910 extreme weather like that experienced this summer was likely to occur once every 500 years, now it is likely to occur every 50 years on average. If climate change remains unabated, researchers say that likelihood could increase even more.

The report said, “In the future, a summer as hot as this past summer in New South Wales is likely to happen roughly once every five years.”

Energy companies in New South Wales had trouble supplying enough electricity to meet the demand for air conditioning units during the heatwave’s most intense days from February 9th through the 11th. Meanwhile, according to report by The Guardian, Australian Prime Minister Malcolm Turnbull criticized renewable energy efforts, calling renewable energy goals in the country “completely unrealistic.”

Dr. Andrew King of Melbourne University was another one of the report’s authors. He said, “Yes, people would have experienced 40C [104 degrees Fahrenheit] days several decades ago around different parts of Australia and in Sydney but we know that these incidences of very hot days are getting more frequent and we are setting more records for heat.”

King added, “The purpose of the analysis in this report is to raise awareness that climate change is already impacting on weather in Australia. Hopefully it motivates action on climate change, because we know what the solution to climate change is.”

Winter tornados move through Midwest

More than 20 tornados ripped through parts of Iowa, Missouri, Illinois, Indiana and Tennessee on Tuesday.

The severe thunderstorms and tornadoes killed at least three people and left thousands of residents in the Midwest and Southeastern U.S. without electricity. While tornados during winter months are rare, they seem to be happening with increasing frequency.

Typically wintertime tornados form when a forceful jet stream moves across the Southern U.S. and meets colder, retreating air fronts. According to The Weather Channel, usually these tornados crop up in the Deep South, however, in February 2016 severe tornados touched down in Pennsylvania and Virginia, ultimately killing seven people.

On average, February is second-least tornadic month of the year, but recently averages for that month are increasing. February 2008 had 146 total tornados, making it the most tornadic February since the 1950s, and February 2016 came close behind with 138 total twisters.

While an abundance of scientific evidence links climate change with the increasing frequency of extreme weather events like heat waves and coastal flooding, the relationship between climate change and tornado frequency remains unclear.

Due to particularly strong jet-stream level energy characteristic of the winter months, winter tornados can occur at any time of the day or night, unlike more predictable spring and summer tornados that almost always form during the late afternoon and evening. The Weather Channel also points out that it is common for winter twisters to be wrapped in rain, making them more difficult to spot.

Experts remind Midwestern and Southeastern U.S. residents that severe weather in the winter months can be deadly and to create or review their severe weather plans.
