The climate emergency is the biggest threat to civilization we have ever faced. However, there is good news: We already have every tool we need to beat it. The challenge is not identifying the solutions, but rolling them out with great speed.
Some key sectors are already racing ahead, such as electric vehicles. They are already cheaper to own and run in many places — and when the purchase prices equal those of fossil-fueled vehicles in the next few years, a runaway tipping point would be reached.
Electricity from renewables is now the cheapest form of power in most places, sometimes even cheaper than continuing to run existing coal plants. There is a long way to go to meet the world’s huge energy demand, but the plummeting costs of batteries and other storage technologies bodes well.

Moreover, many big companies are realizing that a failure to invest would be far more expensive as the impacts of global heating destroy economies. Even some of the biggest polluters, such as cement and steel, have seen the green writing on the wall.
Buildings are big emitters, but the solution — improved energy efficiency — is simple to achieve and saves the occupants money, particularly with the cost of installing technology, such as heat pumps, expected to fall.
Stopping the razing of forests requires no technology at all, but it does require government action. While progress is poor — and Brazilian President Jair Bolsonaro is going backwards — countries such as Indonesia have shown regulatory action can be effective. Protecting and restoring forests, particularly by empowering indigenous people, is a potent tool.
Recognition of the role food and farming play in driving global heating is high, and the solutions, from alternatives to meat to regenerative farming, are starting to grow. As with fossil fuels, ending vast and harmful subsidies is key, and there are glimmers of hope here, too.
In the climate crisis, every fraction of a degree matters and so every action reduces people’s suffering. Every action makes the world a cleaner and better place to live — by, for example, cutting the air pollution that ends millions of lives a year.
The real fuel for the green transition is a combination of those most valuable and intangible of commodities: political will and skill. The supply is being increased by demands for action from youth strikers to chief executives, and must be used to face down powerful vested interests, such as the fossil fuel, aviation and cattle industries.
The race for a sustainable, low-carbon future is on, and the COP26 climate talks in Glasgow, Scotland, would show how much faster we need to go.
Responsible for 14 to 28 percent of global greenhouse gas emissions, transport has been slow to decarbonize, and faces particular challenges in areas such as long-haul flight.
However, technical solutions are available, if the will, public policy and spending are there, too. Electric vehicles are the most obvious: gasoline and diesel vehicles would barely be produced in Europe within the decade. Electric vehicle sales are accelerating everywhere, with the likes of Norway well past the tipping point, and cheaper electric vehicles coming from China have cut the fumes from buses. Meanwhile, combustion engines are ever more efficient and less polluting.
Bike and scooter schemes are growing rapidly, as cities around the world embrace electric micromobility. Far cleaner ships for global freight are coming. The potential of hydrogen is growing, for cleaner trains where electrification is impractical, to be followed by ships and even, one day, planes.
Manufacturers expect short-haul electric aircraft much sooner. Most of all, the COVID-19 pandemic has shown that a world without hypermobility is possible — and that many people will accept, or even embrace, a life where they commute and travel less.

Emissions from technology companies, including direct emissions, emissions from electricity use and other operations, such as manufacturing, account for 0.3 percent of global carbon emissions, while emissions from cryptocurrencies is a huge emerging issue.
Mining — the process in which a bitcoin is awarded to a computer that solves a complex series of algorithms — is a deeply energy-intensive process and only gets more energy-intensive as the algorithms grow more complex. However, new mining methods are lighter, environmentally. A system called “proof of stake” has a 99 percent lower carbon footprint.
Scrutiny of the whole sector is increasing, spearheaded by tech workers who walked out in their hundreds to join climate change marches in 2019. The companies have pledged to do better: Amazon aims to be net-zero carbon by 2040 and powered with 100 percent renewable energy by 2025. Facebook has a target of net-zero emissions for its entire supply chain by 2030 and Microsoft has pledged to become carbon negative by 2030. Apple has committed to become carbon neutral across its whole supply chain by 2030.
They are still falling short when it comes to delivering, but employee groups continue to push.

Deforestation and land use change are the second-largest source of human-caused greenhouse gas emissions. The destruction of the world’s forests has continued at a relentless pace during the COVID-19 pandemic, with millions of hectares lost, driven by land-clearing in the Brazilian Amazon.
However, there are reasons for hope. The UK has put nature at the heart of its COP26 presidency, and behind the scenes, the government is pushing hard for finance and new commitments from forested nations to protect the world’s remaining carbon banks. Indonesia and Malaysia, once global hotspots of deforestation, have experienced significant falls in recent years, the result of increased restrictions on palm oil plantations. However, the 2000s soy moratorium in Brazil shows these trends are reversible.
Finally, there is a growing recognition of the importance of indigenous communities to protecting the world’s forests and biodiversity. In the face of racism and targeted violence, a growing number of studies and reports show they are the best guardians of the forest. Empowering those communities will be vital to ending deforestation.

For decades Exxon Mobil has arguably been the US’ biggest climate change denier. However, this year, the activist investor Engine No. 1 won three seats on the company’s board with an agenda to force the company to finally acknowledge and confront the climate crisis.
Across corporate America and all around the world there are signs of change. The US Federal Reserve, the world’s most powerful central bank, is beefing up its climate team. BlackRock, the world’s biggest investor, has made environmental sustainability a core goal for the company.
This is not about ideology: It is about “common sense.” According to BlackRock, failure to tackle climate change is simply bad for business. The investor calculates that 58 percent of the US would suffer economic decline by 2060 to 2080 if nothing is done.
Much more needs to be done, and some question whether corporate America can really solve this crisis without government action. However, the days of denial are over — what matters now is action.

The rocketing global market price for gas has ripped through world economies, forcing factories to close, triggering blackouts in China, and threatening to cool the global economic recovery from the COVID-19 pandemic.
However, it has also spelled out a clear economic case for governments to redouble their efforts in developing homegrown, low-carbon electricity systems.
The good news is that renewable energy is ready to step up and play a greater role in electricity systems across the globe.
The precipitous fall in the price of wind and solar energy has helped to incentivize fresh investments in electric vehicles and energy storage technologies, such as batteries, where costs are plummeting, too. Soon, wind and solar power will help to produce green hydrogen, which can be stored over long periods of time to generate electricity during days that are a little less bright or breezy.
All of these advances are made possible by cheap renewables, and will help countries to use more renewable energy, too. There has never been a better time to step back from gas and go green.

The built environment is one of our biggest polluters, responsible for about 40 percent of global carbon emissions.
Should we start thinking of buildings as material depots, full of reusable resources for the next construction project?
Over the past two decades, the carbon footprint of buildings “in use” has been greatly reduced by energy-saving technologies — better insulation, triple-glazing and on-site renewables, such as solar panels and ground-source heat pumps. On heat pumps, the UK lags far behind: Norway, through a mixture of grants and high electricity prices, has installed more than 600 heat pumps for every 1,000 households.
As national energy grids are decarbonizing, the focus is shifting to reducing the “embodied energy” of materials — which can account for up to three-quarters of a building’s emissions over its lifespan — for example by reducing the amount of concrete and steel in favor of timber.
There is also a growing movement to prioritize refurbishment and reuse over demolition, driven by the realization that the most sustainable buildings are the ones that already exist.

FOOD AND FARMING
The hoofprint of the global livestock industry is a significant one, accounting for about 14 percent of total annual greenhouse gas emissions. However, it is increasingly recognized and accepted by national governments.
New Zealand now has a legal commitment to reduce methane emissions from agriculture by 10 percent by 2030, while Denmark has passed a legally binding target to reduce climate emissions from the agricultural sector by 55 percent by 2030.
While global meat production is increasing, there is a growing shift toward fish and poultry, which have a comparatively lower emissions footprint than red meats. The food industry is also developing a range of lower-carbon products using plant-based proteins such as soy and pea, and insect and lab-grown meat alternatives.

Decarbonizing the manufacturing of every product needed by a modern economy is a vast and varied task. Some sectors are well on their way. For instance, Apple, the world’s third-largest maker of mobile phones by volume, has pledged to produce net-zero carbon throughout its supply chain by 2030.
For many others, advances in efficiency of factories and their products would be accelerated by machine learning and other artificial intelligence technologies that are still in their infancy. There are even hopeful signs in some of the hardest sectors to decarbonize, such as plans by Volvo to replace coal with hydrogen in the steel it uses in vehicles.
One of the greatest reasons for optimism is manufacturers’ increasing awareness of circular design principles. Making products easier to recycle from the start would help to cut emissions from fresh resource extraction — although a bigger question remains as to whether rich societies can reduce consumption, the most obvious way to cut emissions.

Liberal democracy and communist autocracy are at the initial stages of a historic battle. Taipei has chosen its side in this fight and has sought to frame “cross-strait relations” as an international issue, while Beijing says that Taiwan is an “internal issue” and a hangover from the Chinese Civil War. Taiwan’s status as a nation has new clarity and the international community is beginning to defend Taiwan’s democracy. The Washington Post has praised Taiwan’s diplomatic achievements and Australian Minister for Defence Peter Dutton has said that it would be inconceivable for Australia not to join Taiwan and the US in a conflict with
At a time when China continues its assertive policy toward its neighboring countries, the regime of Chinese President Xi Jinping (習近平) signed a memorandum of understanding (MOU) with Bhutan last month to resolve a longstanding border dispute. However, this is not the first time China and Bhutan have taken such efforts on this issue. Over the years, China has expanded its claim over territory in Bhutan. China claims over 764km2 of Bhutan’s territory, which includes Doklam, Sinchulung, Dramana and Shakhatoe in the northwestern region and the Pasamlung and Jakarlung Valleys in the central part of Bhutan. Although the two sides held
Among the voices expressing concern for Chinese tennis player Peng Shuai (彭帥) over the past two weeks, one was barely audible — that of her long-time former doubles partner Hsieh Su-wei (謝淑薇). Following their defeat in the WTA Finals championship match in Mexico on Nov. 18, Taiwan’s Hsieh and her Belgian partner Elise Mertens fielded questions via a Zoom call. Chinese state media had just released an incredibly suspicious e-mail, purportedly from Peng, and Canadian tennis Web site Open Court broached the issue. With the entire tennis world chiming in, seeking Hsieh’s opinion seemed obvious. However, the Web site’s reporter prefaced her question
At the Sixth Plenary Session of the Chinese Communist Party’s (CCP) 19th Central Committee, held earlier this month, attendees passed the “Resolution of the Central Committee of the Communist Party of China on the Major Achievements and Historical Experience of the Party Over the Past Century.” The resolution divides the CCP’s rule of China into three historical phases. The first phase was led by Mao Zedong (毛澤東), who enabled Chinese to “stand up.” The second phase occurred during the tenure of Deng Xiaoping (鄧小平), who enabled China to “become rich.” The third phase began with Chinese President Xi Jinping (習近平), who
