- Ecuador is now vaccinating very rapidly. 12% of the population received a vaccine in the last week. [here is all our data for countries around the world: ourworldindata.org/explorers/coro…]
- The global COVID-19 vaccination effort is estimated to have saved around 20 million lives — in just its first year.
- The decline of COVID in Israel. This chart is indexed to the peak of cases and shows the relative decline by age group since then. For some time there was a slight temporary rise among younger people (who get vaccinated last). But recently cases declined for all age groups.
- The world has probably passed “peak air pollution”— Global emissions of local air pollutants have probably passed their peak. The chart shows estimates of global emissions of pollutants such as sulphur dioxide (which causes acid rain), nitrogen oxides, and black and organic
- The end of poverty is possible. Each country shown on this chart achieved a large decline in extreme poverty over the last generation. This is one of the most important lessons we can learn from the available data: rapid progress against poverty can be achieved.
- The German-speaking countries stand out in Western Europe: Germany, Switzerland, and Austria in the three last places. [all our data: ourworldindata.org/explorers/coro…]
- Vaccines account for 40% of the decline in infant mortality over the last 50 years. Infant mortality rates have plummeted over the last 50 years. Globally, they’ve fallen by over two-thirds, from around 10% in 1974 to less than 3% today. A recent study — published in The Lancet
- The timing of the peak cherry tree blossom is influenced by spring temperatures. Based on data from Japan stretching back to the year 812 (!), we see that in recent centuries the peak blossom has gradually moved earlier in the year—due to higher temperatures from climate change.
- How many grams of CO₂ are emitted per each kilowatt-hour of electricity? Carbon intensity of electricity across European countries.
- Chile produced 9.4% of its primary energy from solar in 2023 — the highest in any country that year. According to the Energy Institute’s Statistical Review of World Energy, in 2023, Chile produced 9.4% of its primary energy from solar sources, the highest share in any country.
- Weather forecasts have become much more accurate. A four-day forecast today is as accurate as a one-day forecast 30 years ago. The chart here shows the difference between the forecast and the actual weather outcome for forecasts 3, 5, 7, and 10 days in advance. The metric used
- You want to reduce the carbon footprint of your food? Focus on what you eat, not whether your food is local. Transport emissions are very small for most food products.
