California 'rain debt' equal to average full year of precipitation

A new NASA study has concluded California accumulated a debt of about 508 mm (20 inches) of precipitation between 2012 and 2015 - the average amount expected to fall in the state in a single year. The deficit was driven primarily by a lack of air currents moving inland

New source of lead in drinking water identified: Galvanized steel pipe coatings

When unsafe levels of lead are found in drinking water, the culprit has typically been lead pipes or lead-containing brass and bronze fittings, but in a new study researchers clearly show that lead present in the zinc coating of galvanized steel pipes can be a very sign

2015 longer by a leap second

At 23:59:60 UTC on June 30, 2015, a Leap Second will be added, making this day last for 86401 seconds instead of the usual 86400. This practice started in 1972 and since then a total of 25 leap seconds were added to the UTC time, last one in 2012. Correction of each UTC

Minor variations in the ice sheet size sufficient to trigger abrupt climate changes

Over the past one hundred thousand years cold temperatures largely prevailed over the planet in what is known as the last ice age. However, the cold period was repeatedly interrupted by much warmer climate conditions. Scientists have long attempted to find out why these
