Climate change and the move to net zero is a compelling challenge, and this category sets out the science, the costs and the politics. Our posts cover the state of the climate, the Earth’s energy imbalance, sea level rise, the risk of tipping points such as the AMOC, high-intensity rainfall, lethal humidity and the loss of Arctic ice. They also count the costs, from becoming uninsurable and the damage to GDP at 3 degrees of warming to the bill for communities such as New South Wales.
A second theme is who is responsible. Posts examine how a small number of companies drive most emissions, how fossil fuel subsidies run at millions of dollars a minute, and what Big Oil knew about climate science and when. Our latest articles compare a major report built on 101 documents with the growing number of climate court cases worldwide.
We also take on misinformation, with guides to climate denier arguments, the signs of a denier, greenwashing claims and memes for deniers and delayers. Posts on carbon capture and direct air capture ask what works, while others show real progress in shipping, vehicle standards and falling coal use in China. Start here to understand the problem, the people slowing the response, and the solutions that are already working.

A new Center for Climate Integrity report assembles 101 documents showing oil majors understood climate science from the 1950s while funding doubt and delay. Meanwhile climate courts are filling up: 4,993 cases worldwide by October 2026, up from about 3,099 in July 2025.
A Forbes article says climate change is not an existential crisis. That is true but beside the point. Overshoot above 1.5°C, an IPCC built on compromise, and new Australian economics all show that “not existential” is a very low bar.
New UNSW research included in the NSW Net Zero Commission report estimates that current global warming levels of approximately 1.35°C have already caused median economic losses of around 18% for NSW residents, equating to roughly $21,300 less per person annually.
The research indicates that disruptions to global trade and supply chains, rather than local weather events such as bushfires or floods, are the primary driver of these economic losses.
Lethal humidity is a dangerous combination of high heat and high humidity, measured by wet-bulb temperature. When humidity is too high, sweat cannot evaporate from the skin, preventing the body from cooling itself. This causes core body temperature to rise rapidly, leading to heatstroke, organ failure, and potentially death within hours. Climate change increases frequency and intensity of these life-threatening conditions especially in Middle East, India and South East Asia
Twenty companies are responsible for 40% of emissions globally in 2023. Over 2/3rds of them are state owned. Since 1750, just 25 entities have created the climate crisis we are currently facing. Carbon Majors have released their 2023 report and shows emissions continue to rise with over 180 companies contributing to emissions globally.
Many argue the US withdrawal from the Paris Agreement is good news. Wind solar and batteries are so cheap that little fossil fuel electricity is being built even in fossil fuel states. The US risks falling behind China in green technologies, and with substantial reductions in oil consumption from EVs by 2030, fossil fuel exports will plummet,
The scientific consensus is clear: human activity is causing dangerous climate change with potentially catastrophic consequences.
We have passed the point of avoiding some impacts, but immediate action can still limit the damage.
Climate change is a social justice issue, as wealthier nations contribute more to the problem but are less vulnerable to its effects.
Recent publications show a 3°C climate change costs 36% of GDP or $56 trillion. That is like the depression of […]
Climate change is a pressing global issue with far-reaching consequences. Climate change refugees have increased 41% since 2008 with over 32 million refugees today. UNHCR debunks 5 myths with facts highlighting the urgent need for action. Key points include the growing number of people displaced by climate-related disasters, the challenges of predicting future displacement, and the importance of both mitigation and adaptation efforts. We must stope emissions, and build more resilient and sustainable future for all.
Earth’s energy imbalance EEI is caused by greenhouse gases. Leon Simons uses analogies (bombs, sunlight) to show the immense amount of heat trapped (20 ZJ/year). This trapped heat is 33x humanity’s annual energy use and could raise sea levels by 15cm. The goal is to visualize the vast amount of heat our actions cause.
