Organizations I donate money to (and I think you should consider)
Global Health and Development Fund, via Effective Altruism Funds. Roughly $1200/year. Aims to improve health and economic outcomes for the most people for a given amount of money, often in the past countries in the world. Serves as a donation redistributor. Many organizations this fund sends money to are higher-risk, such as organizations that are just starting out.
Project Vesta. Roughly $100/year. Working on an approach to reverse anthropogenic climate change by removing CO2 from the atmosphere and oceans using enhanced rock weathering on beaches. Currently performing basic scientific research.
Gold Standard Marketplace. Roughly $120/year. A platform where I purchase Carbon offsets by contributing to the creation of renewal energy plants in developing countries, e.g. India in my most recent contribution.
