Scientists raise permafrost alarm at UN climate talks

Scientists issued a dire warning today to UN climate negotiators in Bonn of a vicious global warming cycle that will be unlocked with the thawing of carbon-bearing permafrost.

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.

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.

Workers cleared up another five tons of dead fish from the shores of a Rio lagoon where Olympic rowing and canoeing events are due to take place in 2016, bringing to 37 tons the amount removed since last week, officials said on Wednesday.

Human-dominated epoch started in 1610: Study

 The human-dominated geological epoch known as the Anthropocene probably began around the year 1610, with an unusual drop in atmospheric carbon dioxide, scientists say.

World can cut carbon emissions and live well, eco tool shows

 Cutting carbon emissions to limit global temperatures to a 2 degree centigrade rise can be achieved while improving living standards, a new online tool shows.

Tropical forests may be absorbing far more carbon dioxide in response to its rising atmospheric levels than many scientists thought, a new NASA-led study says.

New method to convert CO2 to valuable organic compound

In a bid to reduce the amount of carbon dioxide released into the environment, researchers have discovered a new method to convert the environmental pollutant to a valuable organic compound.

NASA satellite reveals first ever detailed map of how CO2 looks from outer space

NASA scientists have revealed that first global maps created using newest carbon dioxide-monitoring satellite's data, showing one of the most detailed views of CO2 ever created.

Impact of single carbon dioxide emission felt within 10 years

The climate warming caused by a single carbon emission takes only about 10 years to reach its maximum effect, according to a new study which refutes the common belief that today's emissions won't be felt for decades and that they are a problem for future generations.

Now, cognition battery to test astronauts' spaceflight stressors

 Researchers have recently developed a cognitive test battery, dubbed as Cognition, to measure the impact of typical spaceflight stressors like microgravity, radiation, confinement and isolation, exposure to elevated levels of CO2, and sleep loss) on cognitive performance of astronauts.

Cement which reduces CO2 emission developed

The researchers of Switzerland, India and Cuba have come together to develop limestone calcined clay cement (LC3) which will help reduce carbon dioxide emission (CO2) by almost 30 percent.

Arctic sea ice depletion to result in rise of CO2 in atmosphere
Arctic sea ice depletion to result in rise of CO2 in atmosphere

A new study has revealed that Arctic Sea ice helps remove carbon dioxide from the atmosphere and its depletion would result in an increase of atmospheric concentration of the gas.

Sunlight, not bacteria, key to CO2 in Arctic

Sunlight and not bacteria is the key to triggering the production of carbon dioxide (CO2) from material released by Arctic soils, says a significant study.

Rise in Arctic temperatures linked with extreme weather events

A new study has demonstrated that the swift rise in the Arctic temperatures is because of weather extremes in the northern hemisphere such as heatwaves in the US and flooding in Europe.

NASA to launch satellite to track carbon pollution

The US space agency is to launch on Tuesday a satellite that tracks atmospheric carbon dioxide, a leading greenhouse gas that contributes to global warming.
