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.

How the fossil fuel industry turned the plan to solve climate change into a plan to save itself
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.

How to solve climate change and make life more awesome
We already have all the tools we need to fix climate change. We just need to use them.
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.

RETRACTED ARTICLE: The economic commitment of climate change
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.
Reforming the products and processes of the IPCC to enhance its relevance
The Intergovernmental Panel on Climate Change (IPCC) assesses the scientific knowledge on climate change at five to seven year intervals. Exponential growth of the scientific literature has increased the workload for participants and the length of assessment reports. This paper proposes changes to the IPCC’s products and processes to enable it to better meet the needs of its audiences while reducing the growing burden imposed on authors and other participants.
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.
Knowledge infrastructures for the Anthropocene
The technosphere metabolizes not only energy and materials, but information and knowledge as well. This article first examines the history of knowledge about large-scale, long-term, anthropogenic environmental change. In the 19th and 20th centuries, major systems were built for monitoring both the environment and human activity of all kinds, for modeling geophysical processes such as climate change, and for preserving and refining scientific memory, i.e. data about the planetary past. Despite many failures, these knowledge infrastructures also helped achieve notable successes such as the Limited Test Ban Treaty of 1963, the ozone depletion accords of the 1980s, and the Paris Agreement on climate change of 2015. The article’s second part proposes that knowledge infrastructures for the Anthropocene might not only monitor and model the technosphere’s metabolism of energy, materials and information, but also integrate those techniques with new accounting practices aimed at sustainability. Scientific examples include remarkable recent work on long-term socio-ecological research, and the assessment reports of the Intergovernmental Panel on Climate Change. In terms of practical knowledge, one key to effective accounting may be ‘recycling’ of the vast amounts of ‘waste’ data created by virtually all online systems today. Examples include dramatic environmental efficiency gains by Ikea and United Parcel Service, through improved logistics, self-provision of renewable energy, and feedback from close monitoring of delivery trucks. Blending social ‘data exhaust’ with physical and environmental information, an environmentally focused logistics might trim away excess energy and materials in production, find new ways to re-use or recycle waste, and generate new ideas for eliminating toxic byproducts, greenhouse gas emissions and other metabolites.

Man, this preprint is really the gift that keeps on giving.In case people missed my previous PSA : you can't compare the carbon emissions of people and objects. Humans are more than just the work that they do. (Also, that paper makes a lot of false assumptions in general) https://t.co/bZA414J9YI— Sasha Luccioni, PhD 🦋🌎✨🤗 (@SashaMTL) September 19, 2023

To adapt to the changing climate, we need to radically rethink how and why we do the things we do. From technology, to social movements, to economics. The world is at stake. And we can change it.
