CO2 Emission

CO2 emissions are on track to increase global temperatures by over 1.5˚C

CO2 emissions contribute to climate change, which can have serious consequences for humans and their environment. Scientists always debated on surrounding global warming and...
Zebras' stripes are used to control body temperature

Zebras’ stripes are used to control body temperature

Many theories have been proposed on the zebra's stripes, including avoiding predators, better heat regulation and a social function, yet there is still no...

Human activity is responsible for global temperature rise

Human-induced factors such as greenhouse gas concentrations, other occurrences such as volcanic eruptions, solar activity, and air pollution peaks are responsible for global temperature...

A new wood could drop a building’s temperature and reduce cooling costs

Cooling, or air conditioning, is more complicated than heating. According to the US Department of Energy, heating and cooling systems emit over a half...
Operation of the NIST Ambient Radiation Thermometer, which is approximately 60 cm (24 in. long (1) Infrared (IR) light from a fixed-temperature calibrated source (at right, not shown) enters the thermometer enclosure through this lens, which focuses the radiation onto a “field stop,” analogous to the f-stop aperture in photography. (2) A circular metal chopper slices the IR beam into a sequence of pulses. (3) The first lens inside the central cylinder converts the light from the field stop to a parallel beam. (4) The light passes through this insulated cylinder about 30 cm (12 in.) long which is temperature-controlled by a feedback system. Stray radiation is blocked by another stop. (5) A second lens focuses the light onto a pyroelectric detector. (6) The detector output is routed to an amplifier that boosts the signal to readily readable levels. Credit: NIST

Measuring temperature with invisible light

The most common way to check if someone has a fever without a thermometer is to feel the forehead or neck with the back...

High-temperature electronics? That’s hot

Most electronics only function within a certain temperature range. Now, scientists at Purdue University have blended two organic materials together and created electronics that can withstand extreme...
