But when we looked with binoculars, there they were:… Read More

CO2 Boosts Trees, But Ups Damage From Forest Pests

CO2 Boosts Trees, But Ups Damage From Forest Pests

Scientists warn that damage inflicted by tiny forest pests could worsen as carbon dioxide levels rise. Early research suggests that attacks by caterpillars, beetles, termites and other insects in some forests could be enough to cancel out projected increases in tree growth rates. Forests are critical sponges for sucking carbon dioxide out of the ai… Read More
