Climate Change Ignites Global Infectious Disease Alarm

A group of infectious disease specialists published an article in JAMA advocating for increased awareness and preparedness in the medical field to address the evolving threat of diseases due to climate change. They emphasize the need for updated medical training and proactive measures to mitigate global warming’s impact on health. Credit: SciTechDaily.comExperts highlight the connection between climate change and infectious diseases, urging medical professionals to prepare for new disease patterns and advocate for climate…

German climate tech VC raises ‘record-breaking’ €300M first fund

Berlin-based World Fund has filled its coffers with €300M, in what it claims to be the largest first-time fund raised by any climate tech VC in European history.  Founded in 2021, World Fund invests in startups building tech to decarbonise industries from energy and buildings to transport and agriculture. It has already backed 15 early-stage companies, including SpaceForge, which manufactures materials in orbit, and Slovenian startup Juicy Marbles, which makes fake meat whole cuts.  “We look…

Can brightening clouds buy us time to fight climate change?

Brightening Earth’s clouds so that they reflect more sunlight just might cool the planet — that is if we can figure out how to do it without causing any unintended harm. To test the theory out, a group of over 30 leading scientists have written up a research road map that was published in the journal Science Advances yesterday. The paper focuses on how to approach attempts to artificially shade Earth’s surface with marine clouds by spraying saltwater into the air from ships, a strategy called marine cloud brightening…

Climate Change Is Causing Trees To Struggle To “Breathe”

Recent research led by Penn State indicates that trees in warmer, drier environments struggle to absorb carbon dioxide, compromising their ability to counteract climate change. The study highlights an increase in photorespiration—a process where stressed trees release CO2—under these conditions, challenging the efficacy of trees as natural carbon sinks in a warming world. Credit: SciTechDaily.comTrees are struggling to sequester heat-trapping carbon dioxide (CO2) in warmer, drier climates, meaning that they may no longer…

A Dramatic Reversal Is Coming – Deciphering the Arctic Ice Speed Paradox

Recent research indicates that while sea ice in the Arctic Ocean is currently speeding up due to warming temperatures and thinning ice, climate models predict a slowdown during the summer months in the coming decades. This dynamic has significant implications for marine transportation safety, the wellbeing of Indigenous communities, ecosystems, and the global climate system. The study highlights a discrepancy between observational data and model projections, underlining the complexity of predicting sea ice movement and…

How Tesla became the top-selling car company in Norway

Norway has had massive success with EV adoption — 82% of new cars sold in the country in 2023 were electric, according to the Norwegian Road Federation. This high adoption rate can be attributed to the generous subsidies the Scandinavian country has offered to electric vehicle owners as well as its investment in charging infrastructure.Tesla's sales in the country may represent only a sliver of the 1.8 million vehicles the company delivered globally last year, but its importance to the EV maker goes beyond revenue.…

The World’s E-Waste Has Reached a Crisis Point

The phone or computer you’re reading this on may not be long for this world. Maybe you’ll drop it in water, or your dog will make a chew toy of it, or it’ll reach obsolescence. If you can’t repair it and have to discard it, the device will become e-waste, joining an alarmingly large mountain of defunct TVs, refrigerators, washing machines, cameras, routers, electric toothbrushes, headphones. This is “electrical and electronic equipment,” aka EEE—anything with a plug or battery. It’s increasingly out of control.As…
