Climate change facts you need to know

Under current guidelines, the planet is on target to warm up by 2 degrees Celsius in 2050 and by 4 degrees in 2100, triggering serious large-scale problems by the end of the century. UC San Diego's climate scientist V. Ramanathan accurately predicted this trend back in 1980. He says that if we make an effort to adopt existing technology today, we might be able to change our course on climate.

Science Today talks with UC San Diego Chancellor Pradeep Khosla and professor Rob Knight about a new Microbiome and Microbial Sciences Initiative that will advance the study of microbiomes found in the gut and everywhere else on Earth.
