Remembering Mario Molina, who warned about ozone layer depletion by CFC
The Nobel prize winner, an iconic figure in the ozone layer depletion study, died of a heart attack at the age of 77 on October 7. Due to his work, the ozone layer is likely to be healed by the 2080s
Current CO2 emissions greatly outpace ocean CO2 level caused by ancient volcanoes
According to a new study, human activities are leading to CO2 emissions at a rate three to eight times faster than what the volcanic eruptions might have done, which may prove catastrophic to species in water and on land
120,000 year-old footprints in Arabian peninsula point to human presence
A recent study has shed more light on the presence of early humans in the Arabian peninsula after explorers found human footprints on a lakebed surface
COVID-19: Why do some patients suffer brain damage?
A debate continues to rage about whether the brain damage due to COVID-19 in some patients is because of the attack of the virus, or due to an immune response
Climate study of past 66 million years reveals earth’s current temperature rise is unprecedented
The study published in the Science journal concludes that this human-made climate change is far beyond the natural changes that are triggered by the earth’s changing orbit
COVID-19 lockdowns didn’t help in reducing carbon emission: UN report
The report found that due to lockdowns, the daily level emissions of greenhouse gases decreased by 17% in April when compared to 2019. But, as the world went back to work, emissions rose and crossed last year’s levels
Half of the world’s oceans are already affected by human-induced climate change
A recent study of ocean depths shows that 20-55% of the Atlantic, Pacific and Indian Oceans have shown an emergent human-induced signal and it is likely to increase to 40-65% and up to 80% by 2080
COVID-19: deceased patients’ autopsies show remarkable immune failure
Recent studies have found that the deceased patients lack germinal centers in the spleen and lymph nodes. Germinal centers are where mature B cells can proliferate, and undergo mutations so that become long-standing fighters against a pathogen
