A breakdown of the sources of many air pollutants that damage our health and ecosystems.

China is deploying low-carbon investments through its $1.3 trillion Belt and Road Initiative. But many of these projects come with risks of their own. Case in point: Two hydroelectric dams in Argentina could flood cultural heritage sites and harm one of the world’s largest glacial icefields.

Main Takeaways:

• Sea level rise is a long-term effect of climate change. In fact, the oceans are expected to continue rising for centuries even if we stop emitting greenhouse gas now. Scientists expect that the threat from rising sea levels to the Maldives will only grow.
• Atoll islands like those in the Maldives are capable of naturally changing shape as their surrounding sea level rises. This can result in islands gaining land area, but even growing islands are menaced by climate change. Rising sea levels and warming waters make floods more frequent, and they threaten valuable coastal ecosystems like mangroves and coral reefs.
• The people and government of the Maldives are adapting as well, by constructing sea walls around inhabited islands and making new land through land reclamation.

Main Takeaways:

• What global warming does mean: global warming occurs when the average global temperature increases over long time periods of decades or more.
• What global warming does not mean: global warming is not a ‘uniform’ warming across every region on Earth – instead, for a given time period of overall warming, some places will be colder or warmer than the global average.
• The role of carbon dioxide (CO2) in global warming: Scientific evidence clearly shows that rising CO2 levels in Earth’s atmosphere have been the driving force behind recent global warming, trapping excess heat through the greenhouse effect.

Renewable Capacity Statistics 2025 released by the International Renewable Energy Agency (IRENA) today shows a massive increase in renewable power capacity during 2024, reaching 4 448 gigawatts (GW). The 585 GW addition last year indicates a 92.5% share of the total capacity expansion, and a record rate of annual growth (15.1%).
