Mr Trump's Attitude to Climate Change Stinks


Bill Nye has faith students will turn the tide on climate change

June 15 (UPI) -- Scientist and educator Bill Nye says he expects climate change policy to shift quickly -- as soon as the next generation of young students becomes eligible to vote.

"I think the tide will turn very quickly," Nye told UPI in a recent interview. "My prediction is three presidential elections."

Nye believes in a multifaceted approach to climate change -- a combination of public policy and political advocacy, scientific education and technological innovation.

"It's everything all at once," Nye said. "Not doing one thing instead of the other."

His optimism for rapid change is rooted in his faith in young people and their appreciation for the dangers of global warming. Young people realize -- like he does -- that humans have the resources, technology and know-how to power the world's economy with renewable energy sources.

What people lack, at the moment, he says, is the will. That could change with the implementation of a carbon tax, which would force economies to account for the full costs of the environmental the damage caused by burning fossil fuels and releasing CO2 into the atmosphere.

"It would encourage a lot more innovation," Nye said.

The government, Nye says, needs to do a better job of creating a regulatory environment that encourages green energy innovation. He cites the public-private cooperation that produced America's railroad system and the Internet.

"This is doable, what we want to do is work the problem from the bottom up to meet the demands of consumers for electric vehicles and sustainable energy and from the top down to ensure the right policies and regulations are in place to encourage the investment needed to meet those demands," he said.

Nye was in Washington, D.C., last week to recognize the national winners of the 26th annual ExploraVision program, a competition that asks students to conceive of and communicate a scientific technology that will come to fruition 20 years in the future.

One of the winning teams, a group of students from Ward Melville High School in New York, conceived of a solar cell capable of converting a larger percentage of the solar spectra using multi-walled carbon nanotubes.

Nye says innovations like the solar cell technologies imagined by Long Island high-schoolers don't arrive as the result of disruption, but are the results of years and years of steady progress.

Scientific innovation that will allow the United States and other economies to wean off fossil fuels and develop greener energy will come slower.

"I like to discourage the term 'breakthrough' or 'disruptive' or 'outside the box,'" Nye said.

Part of the reason Nye supports ExploraVision is its commitment to young scientists and to scientific collaboration.

"You start in kindergarten," Nye said. "It gets people working from the get-go."

Nye's mantra of everything all at once also applies to science education.

As creator and host of the popular PBS children's science show Bill Nye the Science Guy, Nye is most famous for making science intelligible and engaging for young people. Now he works on a more adult science TV show, in its third season on Netflix. He says his approach to science communication remains largely the same.

"Doing the Science Guy show, intended for 10-year-olds and based on very good research, getting people instilled with the lifelong passion for science, it's the same idea for adults," Nye said. "Listen to people and use language and vocabulary that is understandable."

But unlike children, adults come with ingrained ideas -- and not always the right ones.

"When it comes to grownups and science education, if you have a misconception about vaccines, for example, you have to be presented with a lot of science over the course of two years," Nye said.

Permafrost loss reveals nightmare sink hole


Green electricity isn't enough to curb global warming

"If the Paris targets are to be met, future CO2 emissions have to be kept within a finite budget," said climate scientist Elmar Kriegler.

June 26 (UPI) -- The adoption of clean energies to power electric grids won't be sufficient to meet the Paris climate targets established by the United Nations.

According to new research published in the journal Nature Climate Change, the continued use of fossil fuels for a variety of industrial processes, to power vehicles and heat buildings, is likely to push CO2 emissions beyond manageable levels.

"We focused on the role of fossil fuel emissions that originate in industries like cement or steel making, fuel our transport sector from cars to freight to aviation and goes into heating our buildings," Shinichiro Fujimori, researcher from the National Institute for Environmental Studies and Kyoto University in Japan, said in a news release. "These sectors are much more difficult to decarbonize than our energy supply, as there are no such obvious options available as wind and solar electricity generation."

According to Fujimori and his colleagues, green transportation is essential to meeting CO2 emissions targets.

The Paris agreement called on nations to progressively curtail CO2 emissions in order to limit global warming to 1.5 degrees Celsius. To meet this target, scientists suggest no more than 200 gigatons of CO2 can be released between now and 2100. If current fossil fuel-use trends continue, however, 4,000 gigatons of CO2 will have been emitted by the end of the century.

Authors of the new study argue that relying on carbon capture and storage technologies is a dangerous strategy. Pulling carbon from the atmosphere is likely a necessity, scientists admit, but major industries, including the transportation industry, must also end their use of fossil fuels.

Researchers argue that climate pledges made by individual countries must be strengthened sooner rather than later in order to prevent continued investments in fossil fuel infrastructure, investments that lock in continued CO2 emissions.

"Climate mitigation might be a complex challenge, but it boils down to quite simple math in the end: If the Paris targets are to be met, future CO2 emissions have to be kept within a finite budget," said Elmar Kriegler, a scientist at the Potsdam-Institute for Climate Impact Research. "The more the budget is overrun, the more relevant will carbon dioxide removal technologies become, and those come with great uncertainties."

According to Krieglar, the precise CO2 budget may be difficult to calculate but the solution to the threat of global warming is clear.

Scott Pruitt Must Do His Job, Federal Judge Rules

EPA Administrator Scott Pruitt is being forced to back up his claims with evidence. You know, like in science.

By Brandon Specktor, Senior Writer | June 6, 2018 01:24pm ET
A federal court has ruled that Environmental Protection Agency (EPA) Administrator Scott Pruitt must actually do his job.

Pruitt has publicly claimed that carbon dioxide is not known to be a major cause of climate change. Now, according to Ars Technica, a U.S. district judge for the District of Columbia ruled on Tuesday (June 5) that the EPA must comply with a Freedom of Information Act (FOIA) request to disclose any evidence it has supporting that claim.

The case dates back to a March 2017 television appearance Pruitt made on the CNBC show "Squawk Box," during which he claimed that "there's a tremendous disagreement about of [sic] the impact" of "human activity on the climate," and that human-made carbon emissions are not "a primary contributor to the global warming that we see."

 The administrator's claims flatly contradicted previous scientific reports released by the EPA before Pruitt took office, as well as mountains of evidence supported by an overwhelming majority of climate scientists.

A nonprofit group called Public Employees for Environmental Responsibility (PEER) heard Pruitt's surprising claims and, the next day, filed an FOIA request asking the EPA to disclose any documents that Pruitt used to reach his conclusions. When the EPA refused to comply, PEER sued the agency. (This is not the only lawsuit against Pruitt's EPA.)

At the trial, the EPA argued that the FOIA request was unreasonable and that it "would require EPA to spend countless hours researching and analyzing a vast trove of material on the effect of human activity on climate change," according to a summary released by the court. (Cynics might confuse the EPA's description of responding to an FOIA request as just part of the agency's job).

Judge Beryl A. Howell was unmoved by the EPA's excuses, calling the agency's resistance to a simple request for supporting evidence "both misplaced and troubling."

Howell ultimately ruled that the EPA must comply with PEER's FOIA request and share any documents it has supporting Pruitt's claim that human-made carbon dioxide is not a significant contributor to global climate change. The EPA must comply with the request by July 2 and, if it cannot provide any documents, release a report explaining their absence by July 11.

"When the head of an agency makes a public statement that appears to contradict the published research and conclusions of that agency, the FOIA provides a valuable tool for citizens," Howell concluded. "Compliance with such a request would help ensure an informed citizenry, vital to the functioning of a democratic society."

Failure to comply with this ruling could result in further court appearances, the summary said. On the flip side, failure to reduce global carbon emissions could result in 10,000 years of catastrophe.

Climate Change Accelerating Sea Level Rise...Faster than Expected

An ice shelf near the Eqip Sermia glacier off the coast of Greenland.

CLIMATE CHANGE COULD be accelerating a rise in sea levels to a greater extent than previously thought, researchers have found.
A new study by an international team of polar scientists has discovered that the process of warmer ocean water destabilising ice shelves from below is also cracking them apart from above, increasing the chance they’ll break off.
“We are learning that ice shelves are more vulnerable to rising ocean and air temperatures than we thought,” Christine Dow from the University of Waterloo in Canada, who led the research, said.
“There are dual processes going on here. One that is destabilising from below, and another from above.
“This information could have an impact on our projected timelines for ice shelf collapse and resulting sea level rise due to climate change.”

Two-year study
Over the course of two years, researchers used radar surveys and Landsat imagery (from Earth-observing satellites co-managed by the US Geological Survey and Nasa) to monitor ice shelves in locations such as Antarctica and Greenland.
They found that as warmer salt water erodes channels into the ice that attaches glaciers to stable land, it also generates massive vertical fractures splitting glaciers from above and below. Surface water melting on top of the ice shelves then pours into these cracks, accelerating the problem further.
“This study is more evidence that the warming effects of climate change are impacting our planet in ways that are often more dangerous than we perhaps had thought,” Dow said.
“There are many more vulnerable ice shelves in the Antarctic that, if they break up, will accelerate the processes of sea level rise,” she added.
The study was recently published in Science Advances.

NASA satellites reveal major shifts in global freshwater

News | May 29, 2018

In a first-of-its-kind study, scientists have combined an array of NASA satellite observations of Earth with data on human activities to map locations where freshwater is changing around the globe and why.
The study, published today in the journal Nature, finds that Earth's wet land areas are getting wetter and dry areas are getting drier due to a variety of factors, including human water management, climate change and natural cycles.

A team led by Matt Rodell of NASA's Goddard Space Flight Center in Greenbelt, Maryland, used 14 years of observations from the U.S./German-led Gravity Recovery and Climate Experiment (GRACE) spacecraft mission to track global trends in freshwater in 34 regions around the world. To understand why these trends emerged, they needed to pull in satellite precipitation data from the Global Precipitation Climatology Project, NASA/U.S. Geological Survey Landsat imagery, irrigation maps, and published reports of human activities related to agriculture, mining and reservoir operations. Only through analysis of the combined data sets were the scientists able to get a full understanding of the reasons for Earth's freshwater changes, as well as the sizes of those trends.
"This is the first time that we've used observations from multiple satellites in a thorough assessment of how freshwater availability is changing everywhere on Earth," said Rodell. "A key goal was to distinguish shifts in terrestrial water storage caused by natural variability -- wet periods and dry periods associated with El Niño and La Niña, for example -- from trends related to climate change or human impacts, like pumping groundwater out of an aquifer faster than it is replenished."
Freshwater is found in lakes, rivers, soil, snow, groundwater and ice. Freshwater loss from the ice sheets at the poles -- attributed to climate change -- has implications for sea level rise. On land, freshwater is one of the most essential of Earth's resources, for drinking water and agriculture. While some regions' water supplies are relatively stable, others experienced increases or decreases.
"What we are witnessing is major hydrologic change," said co-author Jay Famiglietti of NASA's Jet Propulsion Laboratory in Pasadena, California, which also managed the GRACE mission for NASA's Science Mission Directorate in Washington. "We see a distinctive pattern of the wet land areas of the world getting wetter -- those are the high latitudes and the tropics -- and the dry areas in between getting dryer. Embedded within the dry areas we see multiple hotspots resulting from groundwater depletion."
Famiglietti noted that while water loss in some regions, like the melting ice sheets and alpine glaciers, is clearly driven by warming climate, it will require more time and data to determine the driving forces behind other patterns of freshwater change.
"The pattern of wet-getting-wetter, dry-getting-drier during the rest of the 21st century is predicted by the Intergovernmental Panel on Climate Change models, but we'll need a much longer dataset to be able to definitively say whether climate change is responsible for the emergence of any similar pattern in the GRACE data," Famiglietti said.
The twin GRACE satellites, launched in 2002 as a joint mission with the German Aerospace Center (DLR), precisely measured the distance between the two spacecraft to detect changes in Earth's gravity field caused by movements of mass on the planet below. Using this method, GRACE tracked monthly variations in terrestrial water storage until its science mission ended in October 2017.

However, the GRACE satellite observations alone couldn't tell Rodell, Famiglietti and their colleagues what was causing the apparent trends.
"We examined information on precipitation, agriculture and groundwater pumping to find a possible explanation for the trends estimated from GRACE," said co-author Hiroko Beaudoing of Goddard and the University of Maryland in College Park.
For instance, although pumping groundwater for agricultural uses is a significant contributor to freshwater depletion throughout the world, groundwater levels are also sensitive to cycles of persistent drought or rainy conditions. Famiglietti noted that such a combination was likely the cause of the significant groundwater depletion observed in California's Central Valley from 2007 to 2015, when decreased groundwater replenishment from rain and snowfall combined with increased pumping for agriculture.
Southwestern California lost 4 gigatons of freshwater per year during the period. A gigaton of water would fill 400,000 Olympic swimming pools. A majority of California's freshwater comes in the form of rainfall and snow that collect in the Sierra Nevada snowpack and then is managed as it melts into surface waters through a series of reservoirs. When natural cycles led to less precipitation and caused diminished snowpack and surface waters, people relied on groundwater more heavily.
Downward trends in freshwater seen in Saudi Arabia also reflect agricultural pressures. From 2002 to 2016, the region lost 6.1 gigatons per year of stored groundwater. Imagery from Landsat satellites shows an explosive growth of irrigated farmland in the arid landscape from 1987 to the present, which may explain the increased drawdown.
The team's analyses also identified large, decade-long trends in terrestrial freshwater storage that do not appear to be directly related to human activities. Natural cycles of high or low rainfall can cause a trend that is unlikely to persist, Rodell said. An example is Africa's western Zambezi basin and Okavango Delta, a vital watering hole for wildlife in northern Botswana. In this region, water storage increased at an average rate of 29 gigatons per year from 2002 to 2016. This wet period during the GRACE mission followed at least two decades of dryness. Rodell believes it is a case of natural variability that occurs over decades in this region of Africa.
The researchers found that a combination of natural and human pressures can lead to complex scenarios in some regions. Xinjiang province in northwestern China, about the size of Kansas, is bordered by Kazakhstan to the west and the Taklamakan desert to the south and encompasses the central portion of the Tien Shan Mountains. During the first decades of this century, previously undocumented water declines occurred in Xinjiang.
Rodell and his colleagues pieced together multiple factors to explain the loss of 5.5 gigatons of terrestrial water storage per year in Xinjiang province. Less rainfall was not the culprit. Additions to surface water were also occurring from climate change-induced glacier melt, and the pumping of groundwater out of coal mines. But these additions were more than offset by depletions caused by an increase in water consumption by irrigated cropland and evaporation of river water from the desert floor.
The successor to GRACE, called GRACE Follow-On, a joint mission with the German Research Centre for Geosciences (GFZ), currently is at Vandenberg Air Force Base in California undergoing final preparations for launch no earlier than May 22.

One Degree Change Doesn't Sound too Bad....What's the Big Deal??

What’s going to happen during that big question mark around the one-degree change? We’re already seeing the impacts of warming. Our weather is changing, and seasons are shifting. Droughts are becoming longer and well, drier. Then, when the rains come, they’re stronger and inundate the now-parched land, causing floods – and  the results are serious.

This Time, It’s Personal.

That’s what’s happening with our weather. But what else is going on? We wouldn’t put up with a person who behaves like that guy.... someone who moves into our environment and changes everything that was normal and comfortable. Why should we wait to take action on climate?

Climate Change Is Rough For People (And The Rest Of The Residents On Planet Earth)

As the seasons shift and unexpectedly extreme events become the norm, wildlife has to adapt – or die.  The climate change shuffle  indicates that species are trying to learn to stay alive.

  The Signs Are Everywhere

Let’s face it – the signs are everywhere. If these species could protest, they would – This is how it would look when a climate change denier is confronted with the wisdom of mother nature.

Despite All the Evidence, Some People Still Just Don’t Get It.

We’re seeing the signs more and more. Strange seasons, extreme weather, hotter heat waves, and species changing their behaviors just to survive. And yet every winter without fail, there’s that one guy who says “So much for global warming!” as soon as the thermometer drops below 32 degrees.

Risky Behavior

Say you surveyed 100 structural engineers, and 97 said a nearby bridge is structurally unsound and driving over it would be dangerous. Would you take the advice of the only three who disagreed, and proceed to drive over that bridge ?
It’s the same thing with climate change: 97 percent (or more) of climate scientists say climate change is real, and caused by humans. So do you believe that other remaining 3 percent and ignore the risks? Here’s what would happen if you apply that same reasoning to other areas.

Trust The Scientists. They Know What They’re Talking About.

That politician did not have a clue what the consensus of scientists believe. And I don't think he cared.
 Scientists are experts in their fields, much like the structural engineers you asked about that bridge. Or the doctors you see at the hospital. That’s why we trust their recommendations. You don’t have to know the minutiae of every scientific study on climate change – you just need to trust valid science on the subject. Most of all, please don’t believe this politician from a recent New Yorker cartoon!

The Times, They Are A-Changin’.

Together, we’ve solved a lot of tremendous problems the world has faced, and made wondrous advances in the span of decades, or even years that naysayers swore could never happen. Just look at computers: They used to take up an entire room. Now they fit in the palm of your hand.
'Not My Earth, Not My Problem' demonstrates the stark difference between advances in our computer technology and advances in our energy systems. Which sparks the question: with all the incredible advances in wind and solar we’ve seen recently, why aren’t we making bigger and faster changes to our energy system?

I have to say it....I'm a big fan of alternative, renewable energy

We can make changes to our energy. In fact, the shift to power our lives – and the economy – with clean, renewable energy is already underway. As Bob Dylan said, the answer is blowin’ in the wind. We can transition from dirty, dated fossil fuel energy to clean sources like wind and solar power. And when it comes to that plan, we’ve got to say it: We’re big fans!

Put Your Knowledge To Use.

Put Your Knowledge To Use. Now that you’ve got the basics, it’s time to take action. You’ve got the drive — help stop climate change by supporting leaders who make climate solutions, like more fuel-efficient vehicles. And who support research into alternative fuels.

Keeping Global Warming to 1.5 Degrees Could Spare Millions Pain of Dengue Fever

The tropical disease is spread by mosquitoes that thrive in the wetter, hotter conditions that accompany climate change.

Faster international action to control global warming could halt the spread of dengue fever in the Western Hemisphere and avoid more than 3 million new cases a year in Latin America and the Caribbean by the end of the century, scientists report.

The tropical disease, painful but not usually fatal, afflicts hundreds of millions of people around the world. There is no vaccine, so controlling its spread by reining in global warming would be a significant health benefit.

The study is one of several recently published that attempt to quantify the benefits of cutting pollution fast enough to keep warming below 1.5 degrees Celsius. It also projects infection patterns at 2 degrees of warming and 3.7 degrees, a business-as-usual case.

Scientists have predicted that climate change could create the wetter, hotter conditions that favor diseases spread by various insects and parasites. This study focuses on one widespread disease and on one geographical region.
Half a Degree Can Make a Big Difference
Published May 29 in the Proceedings of the National Academy of Sciences, ⦁ the study was conducted by researchers from the University of East Anglia in the United Kingdom and the Universidade do Estado de Mato Grosso in Brazil.
It is part of an urgent effort by scientists around the world to collect evidence on the difference between 2 degrees of warming and 1.5 degrees, under the auspices of the Intergovernmental Panel on Climate Change (IPCC), which is due to report on the latest science this fall.

Either target would require bringing net emissions of carbon dioxide to zero within the next several decades, the IPCC has projected, but to stay within 1.5 degrees would require achieving the cuts much more rapidly.
Avoiding 3.3 Million Cases a Year 
Without greater ambition, the study projected an additional 12.1 million annual cases of dengue fever in the Caribbean and Latin America by the end of the century.
By comparison, if warming is held to 2 degrees Celsius from pre-industrial times—the longstanding international climate goal—the number of estimated additional cases in the region falls to 9.3 million.

Controlling emissions to keep the temperature trajectory at 1.5 degrees Celsius would lower that to an annual increase of 8.8 million new cases.
The increase in infection is driven in great part by how a warmer world extends the dengue season when mosquitoes are breeding and biting.

The study found that areas where the dengue season would last more than three months would be "considerably" smaller if warming is constrained to 1.5 degrees Celsius.
Which Countries in the Region are Most at Risk?

The areas most affected by the increase in dengue would be southern Mexico, the Caribbean, Ecuador, Colombia, Venezuela and the coastal regions of Brazil. In Brazil alone, global warming of no more than 1.5 degrees might prevent 1.4 million dengue cases a year.

The study found that under the 3.7 degree scenario, considered "business as usual," dengue fever could spread to regions that have historically seen few cases. Keeping to 1.5 degrees could limit such a geographical expansion.

People living in previously untouched areas would have less built-up immunity and would be more likely to get sick, while public health providers in some such places "are woefully unprepared for dealing with major dengue epidemics," the authors warned.
