DHARAMSHALA: Environmental changes are happening around the world due to unscientific methods used nowadays.

Methane (CH4) is a powerful greenhouse gas and plays a key part in global atmospheric chemistry. Natural geological emissions (fossil methane vented naturally from marine and terrestrial seeps and mud volcanoes) are thought to contribute around 52 teragrams of methane per year to the global methane source, about 10 per cent of the total, but both bottom-up methods (measuring emissions)1 and top-down approaches (measuring atmospheric mole fractions and isotopes)2 for constraining these geological emissions have been associated with large uncertainties.

Alaska: A federal research vessel will launch on a cruise this week to study how Beaufort Sea wind affects plant and animal life in a changing Arctic Ocean.

Even during droughts like the one that swept across Zimbabwe last year, Isaac Siziba and his wife Khumutso had food. Their annual harvest did not consist of water-dependent crops, but of goats.

Typically 20–40 extreme cyclone events (sometimes called 'weather bombs') occur in the Arctic North Atlantic per winter season, with an increasing trend of 6 events/decade over 1979–2015, according to 6 hourly station data from Ny-Ålesund. This increased frequency of extreme cyclones is consistent with observed significant winter warming, indicating that the meridional heat and moisture transport they bring is a factor in rising temperatures in the region.

Agriculture has contributed nearly as much to climate change as deforestation by intensifying global warming, according to US research that has quantified the amount of carbon taken from the soil b

Fish are expected to shrink in size by 20 to 30 per cent if ocean temperatures continue to climb due to climate change, a study has warned.

The Trump administration has decided to disband the federal advisory panel for the National Climate Assessment, a group aimed at helping policymakers and private-sector officials incorporate the go

As conditions warm, fish and wildlife living at the southern edge of their species' ranges are most at risk, according to Penn State researchers who led a major collaborative study of how wood frog
