Wildfires used to die down and even stop at night with cooler temperatures and increased humidity. But a study released Friday says climate change is making burning weather more around the clock in North America because night is becoming warmer and drier. Canadian fire scientists say potential burning hours for fires have increased 36% in the last 50 years. California now has about 550 more fire-friendly hours a year than it did in the 1970s. North American summer nights are warming faster than days, evening relief is evaporating for forests and that means the area of land burned is soaring.

Exploratory oil drilling off the coast of Brazil's Amazon rainforest are reshaping life in Oiapoque, a small city in the poor state of Amapa that is receiving thousand of migrants looking for work. Newcomers are clearing forest for makeshift housing as they wait and hope for jobs that may result from the drilling being done by Petrobras, Brazil's state oil company. While the prospect of economic opportunities is bringing hope, the impacts of unplanned urban growth in a city with already poor infrastructure are being felt. Environmental groups warn a spill could devastate fisheries and wetlands while Indigenous leaders also fear the project threatens their territory and way of life.

March has been the hottest month on record for the continental United States in 132 years, according to federal weather data. The National Oceanic and Atmospheric Administration reports that March's average temperature was 50.85 degrees Fahrenheit, which is 9.35 degrees above the 20th-century norm. This surpasses the previous record set in March 2012. Climate Central meteorologist Shel Winkley highlights the unprecedented nature of this heat, noting the sheer volume of records broken. More than 19,800 daily temperature records were shattered, and 2,200 places set monthly highs. Experts predict that a brewing El Nino could intensify global warmth.
