A recent report by the Inter-American Development Bank (IDB) highlights the high concentration of poverty in Latin America. Across the region, around 89 million people — more than one in seven — live on less than $3.65 a day.

Poverty can be measured using various poverty lines; here, we’re looking at the $3.65 line, which the World Bank uses to define poverty in lower-middle-income countries.

The chart shows that 52.2 million people living under this line are in just three countries — Brazil, Venezuela, and Mexico — representing 59% of the region’s total.

As the report explains, while Brazil and Mexico don’t have the highest poverty rates, their large populations mean they have the largest number of people living below this line. Venezuela, in contrast, has a smaller population but one of the region’s highest poverty rates.

Identifying where poverty is most concentrated can help target efforts to reduce and eliminate it.

One of the most pressing problems I hear from European friends is that they cannot find an affordable place to live. Housing costs represent one of the largest expenses for most Europeans. While many people rent, purchasing a home remains a goal for some.

The chart shows the change in house prices of residential properties purchased by households in 12 countries across the European Union since 2010. In many, prices have increased sharply (even after inflation). Portugal shows the most dramatic increase, with prices rising by 50%.

But this large increase has not happened everywhere. Rises have been more modest in France and Belgium, and prices have actually fallen considerably in Romania and Italy.

These huge differences matter to young Europeans hoping to find their first home after leaving their family house.

It’s often difficult to understand the scale of wildfires globally. That’s because most news coverage focuses on only a few countries.

News headlines might be filled with stories about large fires in Greece, Portugal, the United States, or Canada, but when we look at the data, the global total is no higher than usual.

This is because the global trend is so strongly dictated by the extent of fires in Africa, which we almost never hear about. As you can see in the chart, Africa experiences more than half of the burned area globally every year. In some years, it’s as much as two-thirds of the total.

Whether it’s a “high” or “low” year for wildfires globally largely reflects whether it’s a high or low year for Africa. These global trends don’t tell us much about the extent of wildfires in other regions.

Global air travel collapsed in 2020 as lockdowns and travel restrictions took effect. With fewer flights, CO₂ emissions from commercial aviation fell sharply. The chart shows Egypt as an example, where they dropped by more than half.

As air travel rebounded, emissions rose too — in many countries, they’ve now surpassed pre-pandemic levels. These countries are highlighted in red on the chart.

Emissions from flying make up about 2.5% of global CO₂ emissions, but air travel has one of the highest carbon footprints per passenger. As demand grows, reducing its impact will be important for meeting climate goals.

The peak flowering of cherry trees in Kyoto, Japan, has been recorded since the ninth century. Yasuyuki Aono and colleagues from the Osaka Prefecture University collated this data from historical diaries and chronicles, indicating the dates on which cherry blossom viewing parties had been held or other observations of peak blossom.

In 2025, the peak cherry blossom happened on April 4th.

This long-run data is a proxy measure for how the climate has changed. The onset of cherry blossoms is linked with warmer temperatures. Since the early 20th century, the combined effects of urbanization and higher temperatures due to climate change have gradually moved the peak blossom earlier in the year.

The world is heating up. By the 2010s, the global average temperature of the air above the surface was about 1°C higher than in the 1940s. But some regions are warming much faster.

The chart shows how average surface air temperatures have changed each decade across continents and oceans compared to historical averages.

The Arctic warmed more than any other region — by the 2010s, it was 2.8°C hotter than in the 1940s.

In the Arctic, melting sea ice has amplified this temperature increase: ice reflects sunlight, so having less of it leads to more warming.

Europe was in second. Since land heats up faster than water, its mostly land-based geography has increased its rate of warming. It has also seen a rapid reduction in aerosols from air pollution. These improvements in air quality can inadvertently increase temperatures because there are fewer aerosols to reflect sunlight.

Foreign aid provides millions worldwide with life-saving treatments, emergency food supplies, and humanitarian assistance.

But where does most of this money come from: the governments of rich countries, or wealthy individuals?

95% of foreign aid comes from governments. Less than 5% comes from private philanthropic donors. This data focuses on larger private donations in the form of grants; it does not include the smaller, individual charity donations you or I might make.

This means that those of us living in wealthy democracies — which is many of our readers — play a key role in determining the size of the global foreign aid budget. If we want more aid to reach the world’s poorest, we hold some power through the governments we elect and the priorities we demand of them.

Most of our governments — including my own in the United Kingdom — do not meet the UN’s target of giving 0.7% of their gross national income in aid. In fact, the UK has recently announced plans to cut its aid budget significantly.
