Antarctica has experienced significant temperatures changes,especially since the last glacial period. An international collaboration including scientists from the ISRO and CNRS1 has now challenged previously accepted estimates of these variations,using new measurements published in June 2021 .study highlights the difference in behavior between East and West Antarctica connected by the latitude.
Surface temperature in Antarctica has risen sharply since the last glacial period .understanding this increase keys to understanding changes in climate at any given time and to testing our ability to mode; them . A study involving Indian scientists provided new data .according to new data, the temperature is increased in the last three years. whereas warming since the last glacial period was until now estimate at +9 Degree delicious the entire continent , the new measurement reveals a variation of +10 Degree Celcius in west Antarctica and between +4 and +8 Degree Celsius in east Antarctica.
when ISRO scientists discover "Bryum bharatiensis "in Antarctica, he found many type variations .every fourth and fifth days are very different type variations in the interval itself developed 2-3 lakes and found a different type of species . Based in the central university of Punjab , the biologists have named the species "BRyum bharatiensis".bharati is the Hindu Goddess of learning and the name of one of India Antarctic research stations.
A huge ice block has broken off from western Antarctica into the Weddel Sea ., becoming the largest iceberg globally, earning the name A-76.The iceberg , measuring around 170KM long and 25 KM wide , with an area of 4320sq km, is now floating in the Weddel sea .its joint previous world largest title holder A-23A, approximately 38,80sq km.in size, which has remained in the same area since 1986.
Carbon emission- The world countries emit vastly different amounts of heat-trapping gases into the atmosphere .the chart above and table below are both data compiled by the "International Energy Agency, "which estimates carbon dioxide emission from the combustion of coal , natural gas oil, and other fuels, including industrial waste and non -renewable municipal waste.China's most carbon emission country in the world is 10.06GT. Second is USA5.41GT and INDIA 2.65 GT .
the latest data show that the drastic curtailment of global economic activity and mobility during the first quarter of 2021pushed down global energy demand by 3.8% relative to the last quarter of 2020, .but it is some months slow after covid situation normal human activity is grown fast again carbon emissions.
Last decade main forest in the world like the Amazon forest is carbon emission not absorb it emits carbon dioxide and other gases; other wetland carbons are very less capacity to absorb the carbon dioxide and carbon mono oxide due to decrease the water level and more usable plastics .plastics are formed a layer in the upper side of soil which is not allowed to water in the soil . Sometimes the water is very dust full due to the membrane of the soil is not worked; in the rainy seasons, some places are flooded, and some places are dry plastics layers that are not allowed to water in the soil .
