Keith Briffa, from the University of East Anglia's Climatic Research Unit, said the tropical ocean regions were among the more reliable areas from which to infer large-scale temperature changes.

BBC: NEWS | Science/Nature | World 'warmest for 12,000 years'

The heatwave across Australia in recent weeks has been so intense that the Bureau of Meteorology has had to add a new shade to its colour-coded temperature chart, so the scale now reaches above 50C.

They are carried out at a scale so small that room temperature induces wigglings of the AFM's constituent molecules that would blur the images, so the apparatus is kept at a cool -268C.

BBC: Atomic bond types discernible in single-molecule images

The gravity-based system responded as it was designed to, circulating water and steam in a continuous loop to keep the scale-model reactor at a safe temperature automatically.

CNN: Today/Tomorrow - Helping nuclear plants keep their cool

One of the ways scientists study the CMB is by subjecting the warm and cold spots in the radiation to a detailed statistical analysis, examining the deviations in temperature as a function of their size on the sky - their angular scale.

BBC: The first fractions of a second after the Big Bang

To compare alien planets, Dr. Mendez at the Planetary Habitability Laboratory and his colleagues are creating an Earth Similarity Index that ranks worlds by their resemblance to our own planet, on a scale from zero to one, based on their mass, radius, density and surface temperature.
