Carbon might boost forest, grassland growth but absorption capacity of soil decreases
The new study adds to growing evidence that the terrestrial carbon sink is weaker than once thought.
Lenovo extends 'carbon offset' service to customers in India, Asia Pacific
Customers can choose from a range of projects overseen by the UN and ClimeCo, a voluntary carbon credits producer in the US.
CO2 levels in the atmosphere is 50 percent higher than 18th century
This is despite an unprecedented fall in greenhouse gas emissions in 2020 because of the pandemic.
Peatlands keep a lot of carbon out of Earth's atmosphere, but that could end with warming and development
Although they only occupy three percent of the global land area, peatlands contain about 25 percent of global soil carbon — twice as much as the world’s forests.
Despite lockdowns, pollution pledges, Earth will get more than three degrees warmer by end of 2100
With just over 1C of warming since pre-industrial times, Earth is already experiencing stronger and more frequent droughts, wildfires and superstorms rendered deadlier by rising seas.
Most habitable region for life would have been several miles below Martian surface: Scientists
Scientists examined Mars datasets to see if heating via geothermal heat would have been possible in that area and found that conditions needed for subsurface melting would have been present on ancient Mars
Trees that grow quickly die faster releasing CO2, challenges notion that forests are sinks for carbon emissions
A researcher said that this suggests that fossil-fuel-based emissions can be 'offset' by planting trees (or avoiding deforestation) really does not stand up to scientific scrutiny.
Climate won’t warm as much as we feared, but will cross the limits we've set, scientists say
Researchers explain why relaxed efforts against carbon emissions will not avoid substantial warming.
Bacteria that eats metal, processes carbon accidentally discovered on dirty lab equipment
Such microbes were predicted to exist over a century ago, but none had been found or described until now.

Happy hypoxia in COVID-19: New study may have found possible causes behind this biology-defying complication
In happy hypoxia, a person’s oxygen levels are so low that they should be fainting or experiencing organ damage, but instead, they are seemingly well, until eventually, they collapse
Weird green sand could sequester greenhouse gases and help combat climate change, say scientists
When waves crash over volcanic rocks, they set off tiny chemical reactions which pulls little bit of carbon dioxide out of the air and form hydrocarbonate.
Afforestation could result in loss of biologically valuable forests, be more harmful than beneficial says study
Afforestation is considered to be an efficient way to remove CO2 from the atmosphere but a study finds that the carbon-capture potential was maybe overrated.
Countries need to work together to remove carbon dioxide from the atmosphere in order to avoid climate change
A system needs to be devised where quotas are fairly allocated and countries that cannot fulfil their obligations allowed to trade with those who can remove CO2.
Even with the COVID-19 lockdown pulling the brakes on economies, CO2 emission hit a new record in May
Carbon dioxide recorded at the Mauna Loa Observatory in Hawaii reached 417 parts per million in May, higher than the record of 414.8 ppm set last year.
Humans are responsible for the rising sea levels, climate change; not the change in Earth’s orbit
The largest sea-level decline was witnessed during the last glacial period some 20,000 years ago, the water level dipped to about 121 metres.
UN Secretary-General urges world leaders to use the Coronavirus pandemic to rebuild the world for the better
He said, “Let us use the pandemic recovery to provide a foundation for a safe, healthy, inclusive and more resilient world for all people."
Older forests have a limit to how much CO2 they absorb, planting new forests could help in fight against climate change
Carbon sinks made up of older trees, might be weaker and incapable to absorb the higher levels of CO2 from the atmosphere.
2019 was second warmest year on record, January was the warmest January since 1850: WMO report
WMO secretary-general said seawater is the most acidic it has been in 25 million years which will have negative impacts on the ecosystems.
Early Earth had an atmosphere rich in carbon dioxide, claims study looking at ancient meteorites
Our planet is pelted with space dust and tiny meteorites daily, which make their way through the atmosphere and collect on the surface.
Ozone-depleting substances caused half of Arctic warming, sea ice loss from 1955 to 2005
The ozone-depleting substances have also caused about a third of all the global warming from 1955 to 2005.
