The US space agency has funded researchers to find out how to recycle human excreta into food that can help astronauts sustain on deeper space missions, including Mars.

Rise in CO2 to melt world's glaciers

Just as it did at the close of the last Ice Age 11,000 years ago, rise in greenhouse gases will eradicate many of the world's glaciers by the end of the century, warns a new study.

'Missing' carbon sink found underneath world's deserts
'Missing' carbon sink found underneath world's deserts

 Besides our oceans and plants, the world's deserts may be storing a large portion of carbon dioxide emitted by human activities, a new study suggests.

US and Brazil agree on ambitious climate change agenda

 Ahead of the key Paris climate change summit this year, the US and Brazil today agreed on an ambitious agenda to mitigate the challenges posed by climate change, as they underlined the need for a deal that reflects the principle of common but differentiated responsibilities.

NASA has released data showing how temperature and rainfall patterns worldwide may change through the year 2100 because of growing concentrations of greenhouse gases in Earth's atmosphere.

How unused mobile phones are squandering gold worth 100 million pounds

A new study has revealed that unused mobile phones are actually squandering gold worth 100 million pounds in the UK.

Climate engineering may better protect coral reefs

When it comes to protecting coral reefs from rising seawater temperature, climate engineering could be a better method than conventional carbon dioxide (CO2) mitigation strategies, new research says.

'Poor in India can't pay for 150 years of pollution by West'

India has asked the developed world to bear the "burden of the cross" for pumping carbon dioxide into the air for the past 150 years as a poor man in India cannot be told to pay more for a cleaner planet.

Here's what it'll take to limit climate change to 1.5 degree C by 2100

As per researchers, achieving a 1.5 degree Celsius world is feasible, at least from a purely technological standpoint.

Rise in CO2 ups water-use efficiency of trees

The increase in atmospheric carbon dioxide (CO2) concentration has led to trees using their available water resources more efficiently, says a new research.

Carbon dioxide levels set new record in March: NOAA
Carbon dioxide levels set new record in March: NOAA

A new data by the National Oceanic and Atmospheric Administration (NOAA) has revealed that our planet Earth has exceeded the highest ever recorded level of carbon dioxide (CO2) in the atmosphere surpassing 400 parts per million (ppm) in March, 2015.

As global CO2 breaks records, India faces dilemma

During the week of April 6 to 12, average carbon dioxide (CO2) levels touched 404.02 parts per million (ppm), the highest-ever in recent human history - and 15 percdent above the levels of 350 ppm scientists say is ideal for Earth.

Audi making diesel fuel from water, air

Audi has begun the production of a synthetic diesel fuel "e-diesel" by just using water and air unlike conventional fossil fuels that contains sulphur.

Artificial photosynthesis method turns waste CO2 into fuels

In a breakthrough in artificial photosynthesis, researchers have developed a new system that uses sunlight to convert waste carbon dioxide into valuable chemical products such as biodegradable plastics, pharmaceuticals, and even liquid fuels.

Rapid decline of trees in Amazon rainforest dramatically changing climate
Rapid decline of trees in Amazon rainforest dramatically changing climate

 A new study has revealed that one-tenth of trees have been removed by human activities from Amazon rainforest since 1960s that has led to the climate change.

Commander honoured with Nao Sena medal posthumously

Over a year after the Navy officer Commander Kuntal Wadhwa died in a mishap involving the under-construction warship INS Kolkata, was on Monday awarded Nao Sena Medal (Gallantry) (Posthumously).

How increased CO2 emission led to greatest mass extinction

In a warning of how lethal increased carbon dioxide emission could be, researchers found the greatest extinction of all time that happened 252 million years ago was due to the huge amount of carbon dioxide the Earth's oceans absorbed from volcanic eruptions.

Anaesthetic gases raising Earth's temperature too
Anaesthetic gases raising Earth's temperature too

Anaesthetic gases may help doctors to cause temporary loss of sensation in patients and carry out surgery smoothly, but by accumulating in the Earth's atmosphere, they also contribute to climate change, says a new study.

A pinch of baking soda for better sight?

A pinch of baking soda can help people see better by modifying the visual signal generated by photoreceptors in the eye that detect light, say researchers.
