Black carbon harms health, and traps heat, melts snow and disturbs rain patterns for as long as it is airborne. While long-lived carbon dioxide (CO2 ) needs fast-tracked action to stabilize global temperature rise to within 1.5 degrees Celsius, black carbon needs elimination to contain short-term warming spikes and to …
SCIENTISTS from the University of Michigan in the US have discovered that stony lumps of calcium carbonate, known as otoliths, found in the ears of most fishes, can offer clues to seasonal temperatures thousands or even millions of years ago (Science, Vol 258 No 5085). The finding has given a …
Environmental space may be defined as the total quantity of natural resources that can be used on a sustainable basis, for example, the total quantity of carbon dioxide that can be released into the air by humans without damaging atmospheric processes like the global climate. To ensure equitable distribution of …
