China and UK Join Forces on Climate Change Agreement
The significance of solidarity on climate change grows as the next year's international climate conference in Paris nears. That's one of several reasons why a climate agreement between two countries announced Tuesday meant so much.
For the first time, China and the United Kingdom issued a joint statement declaring the importance of climate change action and a promise to work together on cutting back on fossil-fuel burning and making other "low-carbon transitions."
"Both sides recognize that climate change and air pollution share many of the same root causes, as well as many of the same solutions. This constitutes an urgent call to action," the statement reads.
The countries agree with the Fifth Assessment Report of the Intergovernmental Panel on Climate Change's assessment that fossil fuel divestment must begin now, along with reversing human activity that accelerates greenhouse gas emissions.
"The UK has the diplomatic muscle to help build a consensus on an ambitious global deal on climate change that includes big players like China and the USA, but that won't happen unless political leaders at the highest level get stuck in," Ben Stafford, head of public affairs at wildlife charity World Wildlife Fund-UK, said, according to the Huffington Post.
"[Tuesday's] joint summit was a step in the right direction. The next step is for the Prime Minister to join other world leaders at the UN secretary general's climate summit in September and demonstrate that climate change is as big a priority for him, and the UK, as it was when he became party leader."
On the economic front, the nations announced a few developments surrounding their agreement:
- The UK and China are both engaged in the New Climate Economy project, an international study on the economics of climate change, with findings to be published later this year.
- The UK and China have launched a joint, $34 million research program on low-carbon innovation, including work on offshore renewables, low-carbon manufacturing processes and technologies and low-carbon cities. This builds on strong existing bilateral energy research co-operation in fields including electric vehicles, smart grids, cleaner fossil fuels and energy storage, according to the agreement.
- Last year, the UK and China signed a memorandum of understanding on offshore wind. The companies say this is leading to new policy collaboration to help commercial deployment.
"It's heartening to hear the UK and Chinese governments agreeing on the urgency and importance of climate change policy, helping to build momentum towards a new global climate deal in Paris in 2015," Ruth Davis, a political advisor to Greenpeace UK, said. "It's also clear that for China, reducing crippling air pollution and addressing climate change go hand in hand. But whilst China plans new measures to cap coal use and massively boost investment in clean technologies, the UK Government is stubbornly refusing to regulate our aging coal plants, risking both our respiratory health and our climate change commitments.
"It's the 21st century—we need to wake up and call time on the world's dirtiest fuel."
Every September for the past 11 years, non-profit the Climate Group has hosted Climate Week NYC, a chance for business, government, activist and community leaders to come together and discuss solutions to the climate crisis.

One of nature's epic events is underway: Monarch butterflies' fall migration. Departing from all across the United States and Canada, the butterflies travel up to 2,500 miles to cluster at the same locations in Mexico or along the Pacific Coast where their great-grandparents spent the previous winter.
Millions of People Care About Monarchs<p>I will never forget the sights and sounds the first time I visited monarchs' overwintering sites in Mexico. Our guide pointed in the distance to what looked like hanging branches covered with dead leaves. But then I saw the leaves flash orange every so often, revealing what were actually thousands of tightly packed butterflies. The monarchs made their most striking sounds in the Sun, when they burst from the trees in massive fluttering plumes or landed on the ground in the tussle of mating.</p><p>Decades of educational outreach by teachers, researchers and hobbyists has cultivated a generation of monarch admirers who want to help preserve this phenomenon. This global network has helped restore not only monarchs' summer breeding habitat by planting milkweed, but also general pollinator habitat by planting nectaring flowers across North America.</p><p>Scientists have calculated that restoring the monarch population to a stable level of about 120 million butterflies will require <a href="https://doi.org/10.1111/icad.12198" target="_blank">planting 1.6 billion new milkweed stems</a>. And they need them fast. This is too large a target to achieve through grassroots efforts alone. A <a href="https://www.fws.gov/savethemonarch/CCAA.html" target="_blank" rel="noopener noreferrer">new plan</a>, announced in the spring of 2020, is designed to help fill the gap.</p>
Pros and Cons of Regulation<p>The top-down strategy for saving monarchs gained energy in 2014, when the U.S. Fish and Wildlife Service <a href="https://www.fws.gov/southeast/pdf/petition/monarch.pdf" target="_blank">proposed</a> listing them as threatened under the Endangered Species Act. A decision is expected in December 2020.</p><p>Listing a species as endangered or threatened <a href="https://www.fws.gov/endangered/esa-library/pdf/listing.pdf" target="_blank">triggers restrictions</a> on "taking" (hunting, collecting or killing), transporting or selling it, and on activities that negatively affect its habitat. Listing monarchs would impose restrictions on landowners in areas where monarchs are found, over vast swaths of land in the U.S.</p><p>In my opinion, this is not a reason to avoid a listing. However, a "threatened" listing might inadvertently threaten one of the best conservation tools that we have: public education.</p><p>It would severely restrict common practices, such as rearing monarchs in classrooms and back yards, as well as scientific research. Anyone who wants to take monarchs and milkweed for these purposes would have to apply for special permits. But these efforts have had a multigenerational educational impact, and they should be protected. Few public campaigns have been more successful at raising awareness of conservation issues.</p>

The Rescue Attempt<p>To preempt the need for this kind of regulation, the U.S. Fish and Wildlife Service approved a <a href="https://www.fws.gov/savethemonarch/pdfs/Monarch%20CCAA-CCA%20Public%20Comment%20Documents/Monarch-Nationwide_CCAA-CCA_Draft.pdf" target="_blank">Nationwide Candidate Conservation Agreement for Monarch Butterflies</a>. Under this plan, "rights-of-way" landowners – energy and transportation companies and private owners – commit to restoring and creating millions of acres of pollinator habitat that have been decimated by land development and herbicide use in the past half-century.</p><p>The agreement was spearheaded by the <a href="http://rightofway.erc.uic.edu/" target="_blank">Rights-of-Way Habitat Working Group</a>, a collaboration between the University of Illinois Chicago's <a href="https://erc.uic.edu/" target="_blank" rel="noopener noreferrer">Energy Resources Center</a>, the Fish and Wildlife Service and over 40 organizations from the energy and transportation sectors. These sectors control "rights-of-way" corridors such as lands near power lines, oil pipelines, railroad tracks and interstates, all valuable to monarch habitat restoration.</p><p>Under the plan, partners voluntarily agree to commit a percentage of their land to host protected monarch habitat. In exchange, general operations on their land that might directly harm monarchs or destroy milkweed will not be subject to the enhanced regulation of the Endangered Species Act – protection that would last for 25 years if monarchs are listed as threatened. The agreement is expected to create up to 2.3 million acres of new protected habitat, which ideally would avoid the need for a "threatened" listing.</p>
A Model for Collaboration<p>This agreement could be one of the few specific interventions that is big enough to allow researchers to quantify its impact on the size of the monarch population. Even if the agreement produces only 20% of its 2.3 million acre goal, this would still yield nearly half a million acres of new protected habitat. This would provide a powerful test of the role of declining breeding and nectaring habitat compared to other challenges to monarchs, such as climate change or pollution.</p><p>Scientists hope that data from this agreement will be made publicly available, like projects in the <a href="https://www.fws.gov/savethemonarch/MCD.html" target="_blank">Monarch Conservation Database</a>, which has tracked smaller on-the-ground conservation efforts since 2014. With this information we can continue to develop powerful new models with better accuracy for determining how different habitat factors, such as the number of milkweed stems or nectaring flowers on a landscape scale, affect the monarch population.</p><p>North America's monarch butterfly migration is one of the most awe-inspiring feats in the natural world. If this rescue plan succeeds, it could become a model for bridging different interests to achieve a common conservation goal.</p>
The annual Ig Nobel prizes were awarded Thursday by the science humor magazine Annals of Improbable Research for scientific experiments that seem somewhat absurd, but are also thought-provoking. This was the 30th year the awards have been presented, but the first time they were not presented at Harvard University. Instead, they were delivered in a 75-minute pre-recorded ceremony.

For decades, climate scientist David Keith of Harvard University has been trying to get people to take his research seriously. He's a pioneer in the field of geoengineering, which aims to combat climate change through a range of technological fixes. Over the years, ideas have included sprinkling iron in the ocean to stimulate plankton to suck up more carbon from the atmosphere or capturing carbon straight out of the air.
Solar geoengineering would involve injecting reflective aerosols from high-altitude planes into the layer of the upper atmosphere known as the stratosphere, which stretches between 10 to 50 kilometers (6 to 31 miles) above Earth's surface. The idea is that the aerosol particles would reflect a small amount of sunlight away from the planet, reducing the amount of heat trapped by greenhouse gases and mitigating some of the effects of climate change.
The planned Stratospheric Controlled Perturbation Experiment will send a balloon carrying scientific instruments in a gondola into the stratosphere. The instruments will release a small amount of material — likely ice or mineral dust — to form a kilometer-long plume of aerosol particles (left). Modified airboat propellers will allow the gondola to maneuver above the plume (middle) and lower instruments into the plume to take repeated measurements of how the particles spread through the stratosphere (right).

David Keith envisions using multiple approaches to combat climate change. The red line shows how the impacts of climate change would worsen with a business-as-usual scenario of unabated burning of fossil fuels and other greenhouse gas emissions. Aggressively cutting emissions bends that curve, and removing carbon from the atmosphere offers further cuts, but there are still consequences from the already high levels of carbon dioxide. In this scenario, solar geoengineering would lessen the impact from existing atmospheric carbon dioxide, effectively carving the top off the curve.<p>Some people think we should use it only as a get-out-of-jail card in an emergency. Some people think we should use it to quickly try to get back to a preindustrial climate. I'm arguing we use solar geoengineering to cut the top off the curve by gradually starting it and gradually ending it.</p><p><strong>Do you feel optimistic about the chances that solar geoengineering will happen and can make a difference in the climate crisis?</strong></p><p>I'm not all that optimistic right now because we seem to be so much further away from an international environment that's going to allow sensible policy. And that's not just in the US. It's a whole bunch of European countries with more populist regimes. It's Brazil. It's the more authoritarian India and China. It's a more nationalistic world, right? It's a little hard to see a global, coordinated effort in the near term. But I hope those things will change.</p>
