The scientific evidence is overwhelming. We're seeing the effects of global warming all around us, from more frequent and intense heatwaves, droughts, and wildfires to rising sea levels and more severe storms. The data shows that greenhouse gas emissions are driving this rapid warming, and we're rapidly approaching the point of no return.
There’s a reason why we call it a “climate emergency”

Global Warming in Pipeline Exceeds Prior Estimates; Urgent Actions Needed to Protect Future Generations
Global warming in the pipeline
Eventual global warming due to today’s GHG forcing alone – after slow feedbacks operate – is about 10°C. Human-made aerosols are a major climate forcing, mainly via their effect on clouds.

One Atmosphere: An independent expert reviewon Solar Radiation Modification research and deployment
It is estimated that continuous injection rates of 8–16 Tg of sulphur dioxide (SO2) per year (approximately equivalent to the estimated injection amount of Mount Pinatubo in the single year of 1991) would reduce global mean temperature by 1°C. An operational SAI deployment could be scaled up to produce global cooling of 2–5°C, albeit with diminishing returns at higher rates of injections.
Make Sunsets is dedicated to using stratospheric aerosol injection (SAI) to fight climate change, but we can't do it alone. We need other climate policies and technologies to join forces with us for lasting impact.
International agreements
The Paris Agreement, adopted in 2015 by 196 countries, is a global effort to limit global warming to well below 3.6°F (2°C) above pre-industrial levels and pursue efforts to limit it to 2.7°F (1.5°C). Countries have committed to reducing their greenhouse gas emissions and regularly reporting on their progress.
Renewable energy
Governments, businesses, and individuals are investing in renewable energy sources such as solar, wind, and hydro power. This can reduce greenhouse gas emissions and decrease reliance on fossil fuels.
Energy efficiency
Improving energy efficiency in buildings, transportation, and industry can also help to reduce greenhouse gas emissions.
Carbon pricing
Many governments are implementing carbon pricing policies, such as carbon taxes or cap-and-trade systems, which put a price on greenhouse gas emissions and encourage businesses to reduce their emissions.
Reforestation and afforestation
Planting trees and increasing forest cover can help to absorb carbon dioxide from the atmosphere.
Research and development
Entrepreneurs and researchers are working to develop new technologies and solutions to reduce greenhouse gas emissions and adapt to the impacts of climate change.
