Sydney, 11.04.2022 (SciDev.Net): Climate change poses a serious threat to human health that calls for urgent action and global collaboration on scales seen in the COVID-19 response, says the World Health Organization (WHO).

“If we don’t take action today on planet health, we are putting our future health at risk. And when health is at risk, everything is at risk. That’s what we have learned from COVID-19,” Takeshi Kasai, WHO regional director for the Western Pacific Region said addressing a virtual press conference from Manila on 7 April, World Health Day

“Climate crisis is also a health crisis since climate change affects health in many different ways,” Kasai said, emphasising the need to build sustainable, climate-resilient health systems.

Scientists develop wheat types to resist heat, drought

Sydney, 21.03.2022 (SciDev.Net): Australian scientists have identified a novel combination of genetics that may help wheat survive in hot and dry conditions, thereby increasing yields and assisting farmers to adapt to climate change-induced heat and drought stress.

Wheat is the third-largest grain crop in the world, supplying about 20 per cent of the total calories and protein in the human diet worldwide, notes the research by CSIRO, Australia’s national science agency, published in Nature Climate Change on 7 March.

Researchers have identified three novel alternative dwarfing genes that enable wheat seeds to draw moisture stored twice as deep from the soil than current varieties. “We have genetics that can allow us to sow earlier and deeper up to 120 millimetres while keeping the plants short and allowing for very long coleoptile, which is the shoot that grows from the seed to the soil surface,” says Greg Rebetzke, co-author of the study and chief research scientist at CSIRO Agriculture and Food.

‘Restore tropical forests’ to address climate change

Sydney, 23.02.2022 (SciDev.Net): Restoring biodiverse tropical forests could be a nature-based solution to remove carbon dioxide from the atmosphere and address climate change, scientists show in a study that simulates how forests will respond to future climate scenarios on earth.

According to the study, limiting global warming caused by human activity to less than two degrees Celsius requires rapid reduction in greenhouse gas emissions as well as reduction of carbon in the atmosphere.

Peter Talaas, secretary general of the World Meteorological Organisation, says that sea level rise and the melting of glaciers may continue until 2060 because of carbon dioxide in the atmosphere. “Of course, if we had carbon removal techs we could change the big picture, but so far that’s not the case,” Talaas said at a meeting ahead of the 28 February release of a section of the sixth report of the UN Intergovernmental Panel on Climate Change.
