As Earth’s climate warms, incidences of extreme heat and humidity are rising, with significant consequences for human health. Climate scientists are tracking a key measure of heat stress that can warn us of harmful conditions.
The rapid collapses of two ice shelves on the Antarctic Peninsula over the past quarter-century were most likely triggered by the arrival of huge plumes of warm, moisture-laden air that created extreme conditions and destabilized the ice, researchers said Thursday.
Meeting human needs at sustainable levels of energy use is fundamental for avoiding catastrophic climate change and securing the well-being of all people. In the current political-economic regime, no country does so. Here, we assess which socio-economic conditions might enable societies to satisfy human needs at low energy use, to reconcile human well-being with climate mitigation.
Only a decade or two ago it was widely thought that tropical forests and intact natural environments teeming with exotic wildlife threatened humans by harboring the viruses and pathogens that lead to new diseases in humans like Ebola, HIV and dengue. But a number of researchers today think that it is actually humanity’s destruction of biodiversity that creates the conditions for new viruses and diseases like COVID-19, the viral disease that emerged in China in December 2019,
Sand dunes have declined by 16% between 1970 and 2013, said PC Moharana, principal scientist in natural resource division, Central Arid Zone Research Institute (CAZRI), who has extensively studied the changing environmental conditions in the desert regions. He clarified that the area under the habitat has turned the barren land into a cropped area with stabilisation of sand dunes as old as 10,000 years old while it will create to have an adverse impact on the unhabituated area — flora and fauna.
