Southern Brazil is facing the worst climate disaster in its history. Unprecedented floods have engulfed major Rio Grande do Sul cities, including the capital, Porto Alegre, where 135,000 people have been pushed from their homes, and there is still little end in sight.
With borders closed and entire countries on lockdown because of the coronavirus pandemic, some 2,000 migrants — many of them children under age 5 — have been detained for months in Panama, near the rainforest separating South and Central America.
