Climate Crisis Gets 16 Minutes at Ninth Democratic Primary Debate in Las Vegas
The climate crisis got its moment in the sun during the ninth Democratic primary debate in Las Vegas Wednesday.
The six qualifying candidates discussed the issue for a full 16 minutes, Grist reported. The debate also marked the first time that a climate journalist was numbered among the moderators: Telemundo climate correspondent Vanessa Huac, who has covered environmental issues for more than 20 years.
"People in the United States and all over our planet are realizing that climate change is one of the most important issues of our times," Huac told NPR Tuesday ahead of the debate. "So, this is a great opportunity to really raise this issue and raise important questions to the candidates to see what are the plans, what are the proposals, how are they planning to face this existential crisis that we're facing."
This sense of public urgency around the issue is reflected in the pool of Nevadans who are likely to participate in the Democratic caucus Saturday. Eighty-six percent of them rated climate and the environment as very important or the most important issue of 2020, according to a League of Conservation Voters and Nevada Conservation League poll released last week. The poll also found that the issue came second to health care for most voters when deciding who to vote for. But for Latinx voters, who make up 20 percent of the Nevada voting block, climate was even more important than health care and immigration, InsideClimate News reported.

So how did the candidates address voters' concerns?
Wednesday's climate discussion was kicked off by Jon Ralston of the Nevada Independent, who pointed out that Reno and Las Vegas were among the fastest-warming cities in the country. He then directed his first question at former Vice President Joe Biden.
"What specific policies would you implement that would keep Las Vegas and Reno livable, but also not hurt those economies?" he asked, according to an NBC debate transcript.
Biden first focused on technical solutions, saying he would invest $47 billion in renewable energy and battery technology. He also said he would reverse President Donald Trump's environmental rollbacks and install 500,000 new electric vehicle charging stations in every highway his administration built or repaired.
"And I would invest in rail, in rail. Rail can take hundreds of thousands, millions of cars off the road if we have high-speed rail," Biden said.

Former New York City Mayor Michael Bloomberg, meanwhile, touted his success shuttering 304 of 530 coal plants in the U.S. as part of his Beyond Coal campaign with the Sierra Club. He also said he would rejoin the Paris agreement.
Senator Elizabeth Warren (D-Mass.) repeated her argument that addressing climate change requires addressing corruption in government.
"The first thing I want to do in Washington is pass my anti-corruption bill so that we can start making the changes we need to make on climate," she said. "And the second is the filibuster. If you're not willing to roll back the filibuster, then you're giving the fossil fuel industry a veto overall of the work that we need to do."
One major point of disagreement between the candidates was on whether or not to ban fracking.
Both Sen. Amy Klobuchar, (D-Minn.) and Bloomberg argued that natural gas is a "transitional fuel" between dirtier fuels like coal and renewable energy. Klobuchar said she would review every natural gas permit on a case-by-case basis and only approve them if they were safe. Bloomberg also said it was important to make sure natural gas extraction was done properly to not release excess methane. But he said it was not possible to abandon the fuel.
"We want to go to all renewables. But that's still many years from now," Bloomberg said.
Sen. Bernie Sanders (I-Vt.), on the other hand, has called for a fracking ban within the next five years, and addressed concerns that such a ban would hurt jobs. Sanders said the moment was too urgent not to act, and that the Green New Deal he supports would create as many as 20 million well-paying jobs.
"This is a moral issue, my friends. We have to take the responsibility of making sure that the planet we leave our children and grandchildren is a planet that is healthy and habitable," he said. "That is more important than the profits of the fossil fuel industry."
"We are fighting for the future of this planet," said @BernieSanders. "And the #GreenNewDeal, which I support by th… https://t.co/kTosBHGPCM— LCV – League of Conservation Voters (@LCV – League of Conservation Voters)1582170252.0
Also on the issue of jobs, Warren was challenged on her plan to ban mining and drilling on public lands, which is an important industry in Nevada. Public lands are also potential sources of minerals like lithium and copper necessary for renewable energy technology.
Warren said she would make an exception for minerals that are needed to transition away from fossil fuels.
"If we need to make exceptions because there are specific minerals that we've got to have access to, then we locate those and we do it not in a way that just is about the profits of giant industries, but in a way that is sustainable for the environment," she said.
Another point of disagreement was how to respond to China, which is currently the world's No. 1 emitter of greenhouse gases.
Bloomberg argued that it was important not to "go to war" with China on emissions but rather to negotiate.
"What you have to do is convince the Chinese that it is in their interest, as well. Their people are going to die just as our people are going to die. And we'll work together," he said.
But Former South Bend, Indiana Mayor Pete Buttigieg argued for the need for "hard tools" to ensure emissions fell worldwide.
"I'm a little skeptical of the idea that convincing is going to do the trick when it comes to working with China," he said. "America has repeatedly overestimated our ability to shape Chinese ambitions."
Both Biden and Warren, unprompted, raised the issue of environmental justice.
"[M]inority communities are the communities that are being most badly hurt by the way in which we deal with climate change," Biden said while answering a question about his plans to hold fossil fuel executives accountable for their pollution. "They are the ones that become the victims. That's where the asthma is, that's where the groundwater supply has been polluted. That's where, in fact, people, in fact, do not have the opportunity to be able to get away from everything from asbestos in the walls of our schools."
Warren later spoke up to "make sure that the question of environmental justice gets more than a glancing blow in this debate."

She touted her $1 trillion dollar plan to repair the environmental damage that had already been done to communities of color.
"We have to own up to our responsibility," she said. "We cannot simply talk about climate change in big, global terms. We need to talk about it in terms of rescuing the communities that have been damaged."

Human actions have taken a steep toll on whales and dolphins. Some studies estimate that small whale abundance, which includes dolphins, has fallen 87% since 1980 and thousands of whales die from rope entanglement annually. But humans also cause less obvious harm. Researchers have found changes in the stress levels, reproductive health and respiratory health of these animals, but this valuable data is extremely hard to collect.

A Lot to Learn From Hormones<p>When sampling the blow, we are looking for hormones in mucus as these can be used to gauge psychological and physiological health. We are specifically interested in <a href="https://dx.doi.org/10.1371%2Fjournal.pone.0114062" target="_blank">hormones like cortisol</a> and <a href="https://doi.org/10.1016/j.ygcen.2018.04.003" target="_blank">progesterone</a>, which indicate stress levels and reproductive ability respectively, but can also help determine overall health.</p><p>Additionally, blow samples can detect <a href="https://dx.doi.org/10.1128%2FmSystems.00119-17" target="_blank">respiratory pathogens</a> in the lungs or nasal passages - blowholes evolved from noses after all.</p><p>This health analysis is especially important in areas with oil spills as the chemicals can cause hormonal problems that harm <a href="https://www.carmmha.org/investigating-how-oil-spills-affect-dolphins-and-whales/" target="_blank">development, metabolism and reproduction</a> in dolphins.</p><p>Hormone samples can provide scientists with valuable data, but collecting them from intelligent and unpredictable animals is challenging.</p>
Cetacean Collaborators<p>To build a drone that can stealthily collect spray from moving dolphins, we needed more data on their eyesight and hearing, and this is data that couldn't be collected in the wild nor simulated in a lab.</p><p>We worked with dolphins at facilities like Dolphin Quest in Bermuda, which provides guests opportunities to learn about dolphins while allowing <a href="https://dolphinquest.com/about-us/our-story/" target="_blank">scientists access to animals for noninvasive research</a>. Here the dolphins can swim away if they choose not to work with us, so we had to design the study like a game; the way a kindergarten teacher entertains a class. If the dolphins aren't interested, we don't get to do the science.</p><p>Over the course of hundreds of sessions, we sought to answer two questions: What can dolphins hear and what can they see around their heads?</p><p>To test dolphin hearing, we set up microphones and cameras to record dolphin behavior as we played drone noise in the air. We analyzed the responses to each noise – such as how many dolphins looked at the speaker – and used these as a proxy for their ability to hear the sounds.</p>

Robodolphin doesn't look like a real dolphin, but it doesn't need to in order to train our drone pilots. C.J. Barton / Oklahoma State University / CC BY-ND<p>To build robodolphin, we worked with dolphins trained to "chuff" or sneeze on command to measure spray characteristics. We used high-speed photography to see the dolphins' breath as it moved through the air. Then we conducted high resolution CT scans of a dolphin head and 3D-printed a replica of a nasal passage.</p><p>Now, we have a complete robodolphin and are tweaking its sprays to be nearly identical to the real thing. This will allow us to determine how close we need to get to collect the samples, and therefore, how quiet our drone needs to be.</p>

A Bit of Practice, Then Into the Wild<p>In the next few months, we will test flights over robodolphin with existing drones to determine the timing and strategy for collection. From there, we will fabricate a low-noise drone that can fly fast enough and with sufficient maneuverability to capture samples from wild dolphins. Like a video game, we will use the visual field data to develop approach trajectories to stay in the visual blindspots.</p><p>We plan to test our drones on a truck-mounted robodolphin moving down a runway, then using a boat to simulate realistic conditions. The next steps will involve ocean testing with dolphins trained for open ocean swimming. These tests will determine if our devices can catch and hold the hormones as the drone flies back to a researcher's boat.</p><p>Finally, we will deploy the system to collect data on wild dolphins. Our first goal is to test resident dolphins – animals that live on the coasts and deal directly with boat and oil industry noise – which will allow us to learn more about stress resulting from human impacts.</p><p>Those samples are a way off, but if all goes well we will have a specially built drone capable of flying long distances and capturing samples undetected in a few years. The samples collected will allow researchers to do better science with impact on the animals they study.</p>

Billions worth of valuable metals such as gold, silver and copper were dumped or burned last year as electronic waste produced globally jumped to a record 53.6 million tons (Mt), or 7.3 kilogram per person, a UN report showed on Thursday.
Environmental and Health Hazard<p>Experts say e-waste, which is now the world's fastest-growing domestic waste stream, poses serious environmental and health risks.</p><p>Simply throwing away electronic items without ensuring they get properly recycled leads to the loss of key materials such as iron, copper and gold, which can otherwise be recovered and used as primary raw materials to make new equipment, thereby reducing greenhouse gas emissions from extraction and refinement of raw materials.</p><p>Refrigerants found in electronic equipment such as fridge and air conditioners also contribute to global warming. A total of 98 Mt of CO2-equivalents, or about 0.3% of global energy-related emissions, were released into the atmosphere in 2019 from discarded refrigerators and ACs that were not recycled properly, the report said.</p><p>E-waste contains several toxic additives or hazardous substances, such as mercury and brominated flame retardants (BFR), and simply burning it or throwing it away could lead to serious health issues. Several studies have linked unregulated recycling of e-waste to adverse birth outcomes like stillbirth and premature birth, damages to the human brain or nervous system and in some cases hearing loss and heart troubles.</p><p>"Informal and improper e-waste recycling is a major emerging hazard silently affecting our health and that of future generations. One in four children are dying from avoidable environmental exposures," said Maria Neira, director of the Environment, Climate Change and Health Department at the World Health Organization. "One in four children could be saved, if we take action to protect their health and ensure a safe environment."</p>
Europe Leads the Way<p>While most of the e-waste was generated in Asia (24.9 Mt) in 2019, Europe led the charts on a per person basis with 16.2 kg per capita, the report said.</p><p>But the continent also recorded the <a href="https://www.dw.com/en/the-eu-declares-war-on-e-waste/a-51108790" target="_blank">highest documented formal e-waste collection and recycling</a> rate at 42.5%, still below its target of 65%. Europe was well ahead of the others on this front. Asia ranked second with 11.7%.</p><p>The authors said while more that 70% of the world's population was covered by some form of e-waste policy or laws, not much was being done toward implementation and enforcement of the regulations to encourage the take-up of a collection and recycling infrastructure due to lack of investment and political motivation.</p><p>"You have to think about new economic systems," said Kühr.</p><p>One approach could be that consumers no longer buy the products, but only the service they offer. The device would remain the property of the maker, who would then have an interest in offering his customers the best service and the necessary equipment. The maker would also be interested in designing his products in such a way that they are easier to repair and easier to recycle, Kühr said.</p>
