Record emissions, temperatures and population mean more scientists are looking into possibility of societal collapse, report says

We are on the brink of an irreversible climate disaster. This is a global emergency beyond any doubt. Much of the very fabric of life on Earth is imperiled. We are stepping into a critical and unpredictable new phase of the climate crisis. For many years, scientists, including a group of more than 15,000, have sounded the alarm about the impending dangers of climate change driven by increasing greenhouse gas emissions and ecosystem change (Ripple et al. 2020).

Global average surface temperatures shattered all-time records in 2023 at 1.45 ± 0.12 ◦C above pre- industrial levels (WMO 2024). Worsened by climate change-induced drought, Canadian wildfires burned 18.5 million hectares, nearly three-times more land area than in any previous year on record (NRC 2023).

01 August 2024 – Humanity is facing its greatest emergency, a crisis consisting of many, interlinked, catastrophic risks, the Roundtable on the Human Future has declared. At present humanity has no way to deal with such a crisis – and a global plan of action is urgently needed, it said.

Numerous prominent petroleum geologists have been warning for years about the resources limitations of oil both in the U.S. and globally.  It’s now looking like the wolf is nearing the door.

Population ecologist William Rees, with the University of British Columbia's School of Community and Regional Planning, is reminding denizens of Earth that the planet can only support so many people. In his paper published in the journal World, he points out that many models have been developed over the years that show that only a certain number of animals (such as rats) can live in a given environment—they all show that at some point, a population correction occurs.

Climate change refers to long-term variation in Earth's climate effected by heating imbalances from natural (e.g., solar, volcanic, and internal dynamics) and human sources (e.g., greenhouse gas emissions and land use). Following the onset of the Industrial Revolution, and particularly since the 1960s, global climate has warmed primarily as a consequence of rising greenhouse-gas concentrations in the atmosphere related to industrial activity. This page provides a selection of template maps and timeseries depicting changes in temperature, precipitation, and other aspects of climate over the past century, and how they are projected to change in the future.

Atmospheric soot loadings from nuclear weapon detonation would cause disruptions to the Earth’s climate, limiting terrestrial and aquatic food production. Here, we use climate, crop and fishery models to estimate the impacts arising from six scenarios of stratospheric soot injection, predicting the total food calories available in each nation post-war after stored food is consumed. In quantifying impacts away from target areas, we demonstrate that soot injections larger than 5 Tg would lead to mass food shortages, and livestock and aquatic food production would be unable to compensate for reduced crop output, in almost all countries. Adaptation measures such as food waste reduction would have limited impact on increasing available calories. We estimate more than 2 billion people could die from nuclear war between India and Pakistan, and more than 5 billion could die from a war between the United States and Russia—underlining the importance of global cooperation in preventing nuclear war.

Our World at Risk: Transforming Governance for a Resilient Future

Years before the climate crisis was part of national discourse, this memo to the president predicted catastrophe

Mapping where the earth will become uninhabitable Lethal heat, flooded coastlines, powerful hurricanes, water scarcity: climate models show that by the end of the century, life as normal won’t be possible in many places. Find out where populations are projected to be hit hardest with our 3D interactive visualisation.

The Working Group III report provides an updated global assessment of climate change mitigation progress and pledges, and examines the sources of global emissions. It explains developments in emission reduction and mitigation efforts, assessing the impact of national climate pledges in relation to long-term emissions goals.

Approval of the Intergovernmental Panel on Climate Change (IPCC) Working Group II report on Impacts, Adaptation and Vulnerability in a virtual session (14-25 Feb). Press conference (virtual) at 10:00 a.m. CET (Berlin) on Monday, 28 February 2022 – 04.00 EDT (New York), 09:00 GMT (London), 12:00 EAT (Nairobi), 16:00 ICT (Bangkok) Information about media registration is available here. The deadline for registration is Friday, 18 February 2022.

Here you can find out how many more climate extremes you will face across your lifetime relative to a world without climate change. The results are based on solid science.

Global warming is not only about melting icebergs or expanding deserts. It is something which does happen in our backyard as well. Data and estimates on the mean temperatures at the local level indicate that climate change has been affecting almost every corner of Europe, as mean temperatures have increased by more than 2°C in half a century in multiple areas.

Given today's challenges, we believe that every professional, journalist, student, citizen should have a simple access to critical data about the crisis we face. A data visualization tool made by The Shift Project, the carbon transition think tank.
