However, data of these hyperthermal events are mainly known from the mid- and high latitude regions. However, there is lack of quantitative data from the equatorial or tropical regions.<\/p>\n<p style=\"text-align: justify;\">Researchers from Birbal Sahni institution of Palaeosciences (BSIP), an autonomous institute of Department of Science and Technology, used fossil pollen and carbon isotope data from the Eocene Thermal Maximum 2 (ETM-2), also known as H-1 or Elmo, a period of global warming that occurred around 54 million years ago, to quantify the terrestrial hydrological cycle during that period.<\/p>\n<p style=\"text-align: justify;\">It was during this period that the Indian\u00a0plate lingered near the equator during its journey from the southern to northern hemisphere.\u00a0 This makes the Indian plate a perfect natural laboratory that offers a peculiar opportunity to understand the vegetation-climate relationship near the equator during the ETM-2.\u00a0On the basis of availability of fossils from ETM2, the researchers selected the Panandhro Lignite Mine of Kutch in Gujarat and collected fossil pollen from there.<\/p>\n<p style=\"text-align: justify;\">Analyzing the pollen, they found that when atmospheric carbon dioxide concentration was more than 1000 ppmv near the palaeo-equator, the rainfall decreased significantly, leading to the expansion of deciduous forests.<\/p>\n<p style=\"text-align: justify;\">The study published in the journal Geoscience Frontiers raises important questions about the survival of equatorial\/ tropical rainforests and biodiversity hotspots under increased carbon emissions.
