The Burning Question | Mike Berners-Lee

Summary of: The Burning Question: We can’t burn half the world’s oil, coal and gas. So how do we quit?
By: Mike Berners-Lee


In ‘The Burning Question’, Mike Berners-Lee shines a light on the critical issue of climate change, a topic that, despite being backed by scientific evidence, still faces skepticism and denial from various quarters. In recent years, our planet has endured extreme weather events, record hot and wet conditions, and rapid climate shifts. The book breaks down complex concepts and issues like the role of government pledges, the drawbacks of green technology, and the impediments that hinder individuals from taking action against climate change. The central motif of the book is the urgent need to regulate carbon emissions, shift investments from fossil fuels to sustainable technologies, and engage citizens as everyday leaders.

The Reality of Climate Change

It is no longer a theory that the earth’s climate is changing rapidly. In recent years, various unusual weather patterns have been reported worldwide. A rainfall occurred in Mecca, Saudi Arabia, having a temperature of 109 degrees Fahrenheit, and England had the wettest year on record. Scientific institutions worldwide confirm that human activity’s greenhouse gas emissions are the primary cause. Since the nineteenth century, it has been known that additional greenhouse gases in the air will warm the planet. Carbon dioxide and methane are among the gases that have been released into the atmosphere, continuously accumulating. Recent research shows that man-made carbon dioxide emissions are exponentially increasing. The effects of climate change are real, and it is time to take action.

Climate Change Tipping Points

In 2009, world leaders agreed to limit global warming to 2 degrees Celsius, considered safe at the time. However, the current 0.8°C increase in temperature has caused more damage than expected, such as the loss of one-third of Arctic Ocean summer sea ice and more frequent catastrophic floods. The danger lies in tipping points in our eco-system that could trigger uncontrollable climatic processes, such as the emission of greenhouse gases stored in Arctic soils and the melting of sea ice. These processes cause positive feedback loops, which could flood the air with an uncontrollable stream of greenhouse gases. The scientific community is growing increasingly concerned about hitting these tipping points, and veteran climatologist Jim Hansen has called allowing the world to get 2 degrees Celsius warmer as a “prescription for disaster.”

The Realities of Our Carbon Budget

The world has too much oil, not too little. Although a 2-degree temperature increase is risky for our planet’s climate, recent developments raise doubts that we’ll even be able to keep the temperature below that, largely due to our constant consumption of fossil fuels. Carbon dioxide stays in the atmosphere for so long that the ultimate temperature increase of the planet will not depend on when we emit carbon gases, but how much we emit in total over the years. Our “all-time carbon budget,” which would give us a 50 percent chance of staying within the 2-degree target, is around 3,700 billion tons of carbon dioxide – more than half of which we’ve already used. The major energy companies have ready-to-use fossil fuels equalling 3,000 billion tons of carbon dioxide – nearly twice our remaining carbon budget. Staying within the budget would mean not using the equivalent of $27 trillion in fuel reserves that have already been extracted.

The Pitfalls of Sustainable Development

Most people believe that climate conferences and green technology will solve climate change issues. However, the governments’ failure to meet their set targets and the rebound effects of green technology make this far-fetched. The governments that attended the 2009 United Nations Climate Change Conference in Copenhagen made promises that they haven’t implemented, leading to a rise in temperature to 3.3 degrees. The more significant problem is the rebound effects of green technology, which have canceled out the positive effects intended. When something is produced more cheaply, it is used more, and improving energy efficiency does not necessarily reduce energy usage. The rebound effects refer to the use of the saved energy and money in producing new products, which has an energy impact. Eventually, this cancels out the original energy gains. Therefore, sustainable development is not just about using renewable energy but also about responsible consumption and production patterns.

Climate Change Misinformation

Climate change is a complex issue that often leaves people in disbelief and confusion, making it difficult for them to take immediate action. Fossil fuel companies intentionally misinform the public by spending billions of dollars on lobby groups, PR agencies, and think tanks to persuade politicians and citizens that climate change doesn’t exist or is too expensive to solve. This propaganda has taken many different forms, including TV advertising, textbooks, and online comments attacking climate change. While the most severe impacts of climate change may not be visible at present, it’s imperative that we take action to safeguard our planet and future generations.
