Global projections of macroeconomic climate-change damages typically consider impacts from average annual and national temperatures over long time horizons1–6. Here we use recent empirical findings from more than 1,600 regions worldwide over the past 40 years to project sub-national damages from temperature and precipitation, including daily variability and extremes7,8. Using an empirical approach that provides a robust lower bound on the persistence of impacts on economic growth, we find that the world economy is committed to an income reduction of 19% within the next 26 years independent of future emission choices (relative to a baseline without climate impacts, likely range of 11–29% accounting for physical climate and empirical uncertainty). These damages already outweigh the mitigation costs required to limit global warming to 2 °C by sixfold over this near-term time frame and thereafter diverge strongly dependent on emission choices. Committed damages arise predominantly through changes in average temperature, but accounting for further climatic components raises estimates by approximately 50% and leads to stronger regional heterogeneity. Committed losses are projected for all regions except those at very high latitudes, at which reductions in temperature variability bring benefits. The largest losses are committed at lower latitudes in regions with lower cumulative historical emissions and lower present-day income.
Why unilateral decarbonisation can pay for itself
Anthropogenic greenhouse gas emissions are rapidly warming our planet, with potentially severe economic, social, and health consequences. Conventional estimates of climate damages suggest that while coordinated global efforts are desirable, unilateral action is rarely cost-effective due to a classic free-rider problem. Why should a country bear the costs of reducing emissions when the benefits are shared globally? This column re-evaluates this view in light of new climate damage estimates based on global temperature variation, showing that the economic case for unilateral decarbonisation is far stronger than previously thought.
The macroeconomic implications of extreme weather events: Insights from advanced economies
Extreme weather events are increasing in frequency and intensity, yet their macroeconomic impacts remain poorly understood. This column argues that the highly localised nature of climate-related natural disasters means impacts should be assessed at the subnational level, with explicit accounting for cross-region spillovers. Such an approach uncovers significant adverse effects of about 0.3% of GDP per year in OECD economies, roughly half occurring outside the disaster zone via negative spillovers.
We’re going to miss the 1.5 °C climate target. Now what?
The United Nations Environment Program released a report earlier this month saying the world – which is already experiencing roughly 1.3˚C of warming – will miss the 1.5˚C climate change target set by international negotiators over a decade ago.
Carbon Removal Technologies | YC Request for Startups
Climate change presents an existential threat to humanity. We are already seeing the effects and they are showing up faster and stronger than anticipated. A report by United Nations' scientific panel on climate change released this month expects the atmosphere-on our current trajectory-to warm up by 1.5 degrees Celsius by 2040. Even the effects of a 0.5 degrees increase will have far-reaching consequences. This research indicates that we are already past the tipping point; even if we significantly reduced emissions, climate change would continue (Source IPCC summary C3 section). We believe there's still time to make a change if we look both to renewal energy and CO2 removal.
Correcting climate ‘misperceptions’ may not boost climate action - Carbon Brief
Most people "underestimate" general support for climate change and "overestimate" actual, real-world climate action.
Climate change
Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The modern-day rise in global temperatures is driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, deforestation, and some agricultural and industrial practices release greenhouse gases. These gases absorb some of the heat that the Earth radiates after it warms from sunlight, warming the lower atmosphere. Earth's atmosphere now has roughly 50% more carbon dioxide, the main gas driving global warming, than it did at the end of the pre-industrial era, reaching levels not seen for millions of years.

The numbers are simply mind-blowing: up to £264 billion for a climate “solution” that will increase emissions. Has the government lost its mind?
Victorian Climate Collaboration – Our Policy Platform
Across Australia and around the world, the impacts of climate change are being felt through worsening bushfires, floods, droughts and heatwaves. The impacts we are experiencing now are early signals of far worse to come. Time is rapidly running out to avoid the devastating impacts of a 2°C or warmer world. Every fraction of degree of warming matters and will be measured in lives, species and ecosystems lost or saved.
The Gargantuan Lie That is Collapsing The World’s Climate
Thinking we have time left to address climate change, or that “Net Zero by 2050” will save us, is driving us toward full social collapse in ways that become more obvious with every new broken temperature record.
Doughnut of social and planetary boundaries monitors a world out of balance
The doughnut-shaped framework of social and planetary boundaries (the ‘Doughnut’) provides a concise visual assessment of progress towards the goal of meeting the needs of all people within the means of the living planet1–3. Here we present a renewed Doughnut framework with a revised set of 35 indicators that monitor trends in social deprivation and ecological overshoot over the 2000–2022 period. Although global gross domestic product (GDP) has more than doubled, our median results show a modest achievement in reducing human deprivation that would have to accelerate fivefold to meet the needs of all people by 2030. Meanwhile, the increase in ecological overshoot would have to stop immediately and accelerate nearly two times faster towards planetary boundaries to safeguard Earth-system stability by 2050. Disaggregating these global findings shows that the richest 20% of nations, with 15% of the global population, contribute more than 40% of annual ecological overshoot, whereas the poorest 40% of countries, with 42% of the global population, experience more than 60% of the social shortfall. These trends and inequalities reaffirm the case for overcoming the dependence of nations on perpetual GDP growth4,5 and reorienting towards regenerative and distributive economic activity—within and between nations—that assigns priority to human needs and planetary integrity.

Impact of climate change may be equivalent to 3.3 million years of transformations in tropical vegetation
Changes that took millions of years can now happen in a matter of decades, and this accelerated rythm can be destructive, with dangerous consequences for the planet
Climate doom may discourage climate action, but there’s a way to counter it
One way to guard against misinformation is to empower people to identify climate doom in the first place.
