El mes pasado viajé con mi esposa y mi hija de cinco años para ir a acampar desde nuestra casa en el suroeste de China.

Nuestro destino era una región de la provincia de Sichuan en la que ríos de agua clara bajan de los Himalayas por entre valles estrechos antes de irrigar las fértiles tierras bajas que ayudan a alimentar al país más poblado del mundo. Mi hija, Evelyn, aprendió a nadar el año pasado y estábamos deseosos de zambullirnos en las frescas y espectaculares pozas de las montañas.

Lo que pasó más bien fue que nos encontramos con una prueba atroz de las consecuencias del cambio climático causadas por la histórica ola de calor en China este verano: paisajes devastados, ciudades paralizadas y poblaciones llevadas al extremo.…  Seguir leyendo »

The weather station on Bishop Rock on Mount Everest. Tenzing Gyalzen Sherpa/National Geographic

A new landmark greeted mountaineers nearing the summit of Mount Everest this spring: a seven-foot-tall mast of scientific instruments bolted into the coarse shale of an outcropping known as Bishop Rock. It’s only about 130 vertical feet from the 29,032-foot summit, where one can look down the opposite side of the mountain, into China, and see another weather station about an equal distance from the top.

These installations are the highest outposts of two networks of automatic weather stations that stretch up Everest’s two popular routes. This being Everest, where controversy is no stranger, it wasn’t long before a quibble arose over bragging rights.…  Seguir leyendo »

If you are in the market for an electric vehicle today, there’s a good chance you’ll buy a Tesla.

Fast forward a couple of years, and this may no longer be true. Traditional automakers like General Motors and Toyota — as well as a slew of Chinese companies like BYD, Nio, Xpeng and Li Auto — are making their own electric models available to U.S. consumers.

Indeed, as the rapidly growing market for electric cars surpasses 500 manufacturers, cross-border competition is only getting fiercer. Although Tesla’s U.S. market share of all-electric vehicles was 79 percent in 2020, it may drop to 56 percent by the end of the year.…  Seguir leyendo »

“Disappointing”. “A shadow on the global climate effort”.

Even before the global climate summit in Glasgow got underway last week, environmental advocates were quick to point fingers at China’s seemingly lackluster “new” climate pledge as a harbinger of a doomed outcome for the event.

Since China is the world’s largest emitter of greenhouse gases, some climate watchers had hoped Beijing would make a big splash with its updated targets to fight climate change — like providing an earlier-than-2030 peak emissions year or a hard cap on coal consumption. But the pledge only consolidated the elements of what President Xi Jinping announced in his landmark carbon-neutrality promise last year and immediately following.…  Seguir leyendo »

“China will step up support for other developing countries in developing green and low-carbon energy”, said China’s president, Xi Jinping, at the United Nations on Tuesday, “and will not build new coal-fired power projects abroad”.

It was a short, ambiguous and not entirely unexpected sentence, but it came at a critical moment. UN-led climate talks in November at Cop26 in Glasgow will represent the first opportunity since the signing of the 2015 UN Paris agreement for countries to ratchet up the commitments in their pledges, known as nationally determined contributions (NDCs). Countries need to increase their NDC ambitions by five times if the world is to reach the goal of not warming by more than 1.5C above pre-industrial levels.…  Seguir leyendo »

Sea level rise, changes in precipitation, more frequent extreme weather-related events and the increasing spread of infectious diseases, such as dengue fever, threaten the availability of food, water and healthcare for people around the world. But action needs to be taken not just internationally, but nationally, if the world is to avoid the most dangerous consequences of the climate crisis.

China and the world

China is key to ensuring a stable climate. It is one of the countries most sensitive to the impacts of climate change, with a higher warming rate than the global average, but it is also the world’s largest emitter of greenhouse gas emissions.…  Seguir leyendo »

Even as the United States and China confront deep disagreements, there is a global challenge that simply won’t wait for the resolution of our differences: climate change.

While some have decided that we are entering a new Cold War with China, we can still cooperate on critical mutual interests. After all, even at the height of 20th-century tensions, the Americans and the Soviets negotiated arms control agreements, which were in the interests of both countries.

Climate change, like nuclear proliferation, is a challenge of our own making — and one to which we hold the solution. We have an opportunity this month to make clear that great power rivalries aside, geopolitics must end at the water’s edge — at the icy bottom of our planet in the Southern Ocean, which surrounds the entire continent of Antarctica.…  Seguir leyendo »

At long last, a handful of political leaders are starting to set goals on greenhouse emissions that are consistent with the magnitude of the climate crisis.

One of the boldest strokes yet came early this week from Gov. Jerry Brown of California. He signed a bill establishing a legal target of zero emissions for the state’s electricity system by 2045. Additionally, in a leap of imagination that nobody saw coming, he signed another document: an executive order setting a goal of zero emissions by 2045 for the entire California economy, not just electricity. That includes cars, trucks, agriculture and every other activity that puts emissions into the air.…  Seguir leyendo »

China’s Other Big Export Pollution

While President Trump rolls back environmental protections and announces the withdrawal of the United States from the Paris climate accord, China is trying to position itself as the world’s climate leader, pledging to cooperate with other countries to build an “eco-civilization”. China has established the largest solar panel farm in the world, plans to close over 100 coal-fired power plants, and is committed to spending at least $361 billion on renewable energy by 2020.

All of this is laudable and sorely needed. But if China truly wants to be a climate leader it needs to address its global climate footprint, not just pollution within its borders.…  Seguir leyendo »

Le Maroc accueille à Marrakech, du 7 au 18 novembre, la « conférence des parties » (COP22) à l’accord sur le réchauffement climatique. La présidence marocaine de la COP22 ne veut pas d’une simple « COP de mise en œuvre » de l’accord de Paris, conclu à l’issue de la COP21 de décembre 2015 ; elle souhaite en faire une COP de l’Afrique et des Sud. Compte tenu de la stratégie chinoise, il faut s’attendre à voir émerger à Marrakech une alliance objective entre la Chine et l’Afrique.

D’abord, le Sud est pressé. L’Initiative africaine pour l’adaptation (AAI), projet panafricain signé lors de la COP21, a posé une priorité : mobiliser la finance pour l’adaptation au changement climatique.…  Seguir leyendo »

Whether China is a climate hero or a climate villain is a matter of polarized debate. At one extreme, the world’s biggest carbon-emitter is portrayed as a wasteful bogeyman that obstructs efforts to halt global warming and “steals” clean-tech jobs through unfair practices. At the other extreme, people see Beijing’s policies as the planet’s best hope: With its aggressive plans to green its economy, backed by the mighty Communist machine, China is the foremost investor in renewable energy. The truth lies in between.

But recently China has done a canny job of presenting itself in the latter, greener light. The main reason for the more hopeful mood among some climate watchers is an accord signed by China and the United States during President Obama’s trip to Beijing in November.…  Seguir leyendo »

For China, pollution and climate change are not the same problem

Beijing is one of the most polluted cities in China, according to official statistics.

Every time China hosts a major international event the government has to take extraordinary measures to clean up the air and avoid suffocating its prominent guests in a dangerous choking smog. On social media, residents ask why the government can clean up for foreigners but can’t provide a healthy environment for ordinary citizens who live and work in the city.

Beijing ordered a special anti-smog campaign for China’s coming out party at the 2008 Olympic Games and again for the Asia Pacific Economic Cooperation (APEC) summit last week, closing factories and ordering traffic restrictions.…  Seguir leyendo »

Algunos podrían considerarlo un desenlace inesperado, pero China -hoy en día el mayor emisor de dióxido de carbono del mundo- se está perfilando como un líder global en materia de política climática en su intento por crear una economía más limpia y más eficiente. Por cierto, los esfuerzos de China para frenar la contaminación y la destrucción medioambiental, a la vez que adopta un modelo de crecimiento más sustentable, pueden ofrecer lecciones valiosas para los gobiernos de todo el mundo.

El primer paso hacia un crecimiento económico sustentable es reconocer, como lo han hecho los líderes de China, que la contaminación -generada en gran medida por centrales eléctricas a carbón- afecta profundamente la vida y el sustento de los ciudadanos, particularmente en ciudades importantes como Beijing y Shanghái.…  Seguir leyendo »

With the disastrous oil spill in the Gulf, talk has once again turned to clean energy. What few people appreciate is that the demand for everything from solar panels to energy-efficient light bulbs is already booming. Worldwide, $162 billion was spent in new clean-tech investments in 2009 alone.

The United States, with its expertise, capital and entrepreneurial spirit, is well positioned to dominate what could easily be the biggest market of the 21st century. But as the most recent delay over the Senate energy bill shows, the country is missing a key ingredient in shaping an effective clean-tech policy: the political will to encourage the innovation, manufacturing and investment necessary to bring these new technologies to market.…  Seguir leyendo »

Tema: El informe anual que publicó el pasado mes de noviembre la Agencia Internacional de la Energía y, sobre todo, algunos de los argumentos que ciertos países desarrollados emplearon durante la reciente Cumbre de Bali sobre el cambio climático han pretendido censurar, de manera más o menos explícita, a los dos grandes países emergentes asiáticos.

Resumen: Tanto en el informe de la AIE como en algunos argumentos esgrimidos durante la Cumbre de Bali, las dos grandes economías emergentes asiáticas (China e India) han sido prácticamente acusadas de ser co-responsables de los graves problemas energéticos y medioambientales del planeta. Esas acusaciones carecen de fundamento.…  Seguir leyendo »

China is about to emerge as the world's leading emitter of greenhouse gases, a position the United States has held since 1890. Now is the time for China to take the lead in finding a way to reduce global emissions, which the United States has thus far failed to do. It should start by imposing a sizable tax on the carbon content of its fossil fuel consumption and by heading an effort among other major trading countries to do the same.

China would gain in several ways from implementing a substantial carbon tax. By reducing its fossil fuel consumption, China would prevent the deaths of hundreds of thousands of citizens because of the short- and long-term consequences of air pollution from burning coal.…  Seguir leyendo »

There was one place where China's assumption of the title of the world's largest emitter of greenhouse gases came as no surprise: Beijing has anticipated and planned for this moment. Until earlier this year climate change was hardly mentioned in the Chinese media. Now the government is encouraging newspapers, radio and television to report on the subject, beginning the long process of educating the population - which increasingly defines itself by what it owns - to understand the long-term consequences of a level of consumption they have only recently been able to enjoy. At government level, a series of briefings by climate-change experts for the leadership, and a policy effort that involved 17 ministries, produced China's first national climate-change plan this month.…  Seguir leyendo »

Tema: A principios del mes de junio China desveló su Programa Nacional sobre Cambio Climático, un documento que ha generado cierta controversia y que ha hecho que, desde algunos sectores de opinión, se cuestione si la posición de Pekín en la lucha contra el calentamiento global es todo lo responsable que debería ser.

Resumen: Este análisis argumenta, en primer lugar, que el reciente Programa chino sobre cambio climático es una iniciativa de la mayor importancia para el conjunto del mundo. En segundo término, resume los aspectos más importantes del Programa. En tercer lugar, expone las críticas principales que ha recibido, así como los argumentos que se han esgrimido en su defensa.…  Seguir leyendo »

By Elizabeth Economy, director for Asia studies at the Council on Foreign Relations (THE WASHINGTON POST, 03/12/06):

Last month the International Energy Agency announced that China would probably surpass the United States as the world's largest contributor of the greenhouse gas carbon dioxide by 2009, more than a full decade earlier than anticipated. This forecast could spur China to adopt tough new energy and environmental standards, but it probably won't. China has already embarked on a very different strategy to manage its environmental reputation: launching a political campaign that lays much of the blame for the country's mounting environmental problems squarely on the shoulders of foreigners and, in particular, multinational companies.…  Seguir leyendo »
