An international team of researchers has used a new modeling technique to estimate that by the year 2100, the world’s cities could warm by as much as 4.4 degrees Celsius on average.
From the rapid development of vaccines for Covid-19 to the stunning collection of an asteroid sample, these were the biggest science moments of the year.
Antarctic iceberg A-68A has drifted menacingly close to a remote island in the southern Atlantic Ocean. The giant iceberg could strike land this month. It has now split into 2 pieces.
Trillions upon trillions of microbes have remained locked away in the Arctic’s permafrost in a “deep sleep” for thousands of years. But the Arctic is warming twice as fast as the rest of the world in the wake of climate change.
The threshold for dangerous global warming will likely be crossed between 2027 and 2042 - a much narrower window than the Intergovernmental Panel on Climate Change's estimate of between now and 2052.
With low oxygen concentrations increasing in lakes and reservoirs across the world, these ecosystems will produce higher concentrations of methane in the future, leading to more global warming.
The industrial slowdown due to the COVID-19 pandemic has not curbed record levels of CO2. Carbon dioxide levels saw another growth spurt last year past 410 parts per million on average.
Sentinel-6 satellite lifted off on a SpaceX Falcon 9 rocket on Nov 21. Its mission now is to measure and chart the rise of the sea level more precisely than ever before.
The human-caused climate change made the ‘Day Zero’ drought in southwestern South Africa — named after the day when Cape Town’s municipal water supply would need to be shut off — five to six times more likely.
Recent findings suggest that relatively close supernovas could theoretically have triggered at least four disruptions to Earth's climate over the last 40,000 years. What happens in space may not always stay in space.
Between 2015 and 2018, some 14 million older, poor quality vehicles were exported from Europe, Japan and the US. Four out of five were sold to poorer countries, with more than half going to Africa.
For the first time since records began, the main nursery of Arctic sea ice in Siberia has yet to start freezing in late October. The delayed annual freeze has been caused by extreme warmth.
This new tool allows you to move around the world to see how concentrations of the powerful greenhouse gas vary in space and time. Just like CO2, Methane (CH4) is increasing in the atmosphere. It is now above 1,876 ppb.
After 13 months of collecting data, history’s largest Arctic research expedition returned with grim news. “We witnessed how the Arctic Ocean is dying,” the mission leader said.
Concentration of N2O in the atmosphere increases strongly and speeds up climate change. In addition to CO2 and methane, it is the third important greenhouse gas emitted due to anthropogenic activities.
