Scientists test technology - want to make the clouds brighter
Scientists in the United States have, for the first time in the country's history, conducted outdoor tests of a machine designed to make clouds brighter. The New York Times writes.
Lighter clouds reflect more sunlight, which means less radiation reaches the earth, which in turn means less warming.
- With each passing year, climate change and temperatures set new records. It drives the research field to investigate more options, says Robert Wood, one of the researchers behind the project.
The machine, which works by spreading salt particles in the air, is described as being a long way from being able to be used practically.

Study: "Mining boom" in Africa threatens 180,000 monkeys
The hunt for minerals such as copper, lithium, cobalt and nickel poses a threat to up to 180,000 gorillas and chimpanzees in Africa, according to a new study according to The Guardian.
The minerals are used in wind turbines and electric cars, and the shift to renewable energy has led to a "mining boom" that is causing destruction to the habitats of already threatened species, according to the study published in Science Advances.
- A transition from fossil fuels is good for the climate, but it must be done in a way that does not endanger biological diversity, says one of the report's authors.
The conclusion is based on data from mining projects in 17 countries and the effect is worst in West Africa. In Guinea alone, 23,000 chimpanzees may be affected, which corresponds to 83 percent of the population.

Five years after the mass death - now there are more gray whales again
The population of gray whales on the American west coast seems to have grown stronger after declining for several years, several media reports. The number is estimated at between 17,400 and 21,300, compared to last year's estimate of between 13,200 and just under 16,000, which was a decrease from the previous year.
- It's nice to be able to report some good news, says biology researcher Aimee Lang.
The Seattle Times writes that the figures are released just five years after what has been called an "unusual death event" when several hundred dead whales were washed ashore.
