Scientists on Tuesday confirmed that last month was the hottest March on record, extending an extraordinary run of global heat that has renewed calls for an urgent reduction in planet-warming greenhouse gas emissions. The record-breaking run stretches back to June last year. "The global average temperature is the highest on record, with the past 12 months being 1.58°C above pre-industrial levels. Chloe Brimicombe, a climate researcher at Austria's University of Graz, told CNBC that yet another month of record-breaking global heat was due to human-caused climate change. "It could be one very long hot summer and not in a good way."

☆ Climate change: Parts of tropical rainforests could get too hot for photosynthesis, study suggests

CNN —Some leaves in tropical forests from South America to South East Asia are getting so hot they may no longer be able to photosynthesize, with big potential consequences for the world’s forests, according to a new study. They found that average forest canopy temperatures peaked at 34 degrees Celsius (93 Fahrenheit) but some exceeded 40 degrees Celsius (104 Fahrenheit). This level of warming is not expected under current climate policies, which are estimated to bring 2.7 degrees Celsius of warming above pre-industrial levels. While these figures may seem small, the risk is significant given how critical tropical trees are for life, the climate system and the planet. But, he added, there are more immediate concerns for tropical forests, including deforestation, wildfires and droughts.

☆ Europe is struggling with a precarious water situation ahead of another drought-riven summer

European policymakers are battling to get to grips with a growing water crisis ahead of what researchers fear could be yet another climate crisis-fueled summer of drought. Water resources in Europe are growing increasingly scarce because of the deepening climate emergency, with record-breaking temperatures through spring and a historic winter heatwave taking a visible toll on the region's rivers and ski slopes. Reservoirs in Mediterranean countries like Italy have fallen to water levels typically associated with summer heatwaves in recent weeks, threatening agricultural production, while protests have broken out over water shortages in both France and Spain. It comes as temperatures are poised to climb through summer and many fear Europe's already "very precarious" water problem could get even worse. "We are actually getting problems with the water supply here — we have to think about this."

Summary Higher-than-expected excess deaths from Europe's heatwaveMany deaths due to high temperature may be under-reportedHeatwaves to become more frequent and intense in futureNov 24 (Reuters) - Summer heatwaves in France, Germany, Spain and Britain led to more than 20,000 "excess" deaths, a report compiling official figures said on Thursday. A heatwave in 2003 caused more than 70,000 excess deaths across Europe, largely in France, and led many countries to implement measures such as early warning systems, asking people to check on others and opening air-conditioned schools. France reported about half of the summer's excess deaths in Western Europe, with 10,420 fatalities in total. Excess deaths reached 3,271 in England and Wales during the summer, Britain's Office of National Statistics reported. Spain recorded 4,655 heat-attributable deaths between June and August while the German health agency reported 4,500.

☆ Найдено наиболее эффективное лекарство от старости

Сам Лев Троцкий, говорил, что "старость — это когда знаешь все ответы, однако никто тебя уже не спрашивает". И вот на днях австрийские ученые из университета Граца (University of Graz) установили, что одним из наиболее эффективных веществ от старения является спермидин. Он заключался в том, что в питание организмов добавляли спермидин. Дрожжи, растущие на питательной среде с добавлением указанного полиамина, живут в четыре раза дольше, а человеческие клетки – в три раза. Во время исследования на мышах стало понятно, что грызуны, которые употребляли пищу с полиаминами, жили гораздо дольше, чем другие особи.
