For many years, scientists have sounded the alarm about climate change, and UN Secretary-General António Guterres has declared code red for humanity. The alarm bells are deafening, and the evidence is irrefutable: greenhouse gas emissions from fossil fuel burning and deforestation are choking our planet and putting billions of people at immediate risk.

This year has been no exception. We are becoming intensely aware of the climate emergency unraveling right before our eyes. In the summer of 2022, we saw record temperatures across the globe, massive wildfires, flooding, and droughts. As an example, the United Kingdom experienced three massive heatwaves in June, July, and August leading to extreme temperatures, more wildfires than average, and droughts declared in many regions across the country. In London, Google and Oracle had to shut down servers in their data centers due to the heatwave. In the United States, Lake Mead and Lake Powell, two artificial Colorado River water reservoirs, shrunk massively in capacity, threatening the energy and power supply for tens of millions of people. Maybe the most significant event was the travesty unfolding in Pakistan due to the tremendous flooding, leaving one-third of the country under water and over 30 million people being forced to leave their homes.

The facts that are on the table are crystal clear. The need to act has never been more urgent. We need to limit the global temperature rise to well below 2 degrees Celsius, preferably around 1.5 degrees. Reaching net-zero emissions is often expressed in target dates, such as halving greenhouse gas emissions by 2030 and achieving net zero in 2040 or 2050. In this book, I will continuously refer back to net zero or net positive, which should be our ultimate goal.
