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…

Nearly $200 million invested in food security in Nigeria—US Embassy

The Head of the United State Embassy in Nigeria, David Greene, says the United States’ government has for over five years invested about $200 million in food security in Nigeria through its international development agency. The official made the disclosure Thursday while delivering his remarks during the launch of the US government’s Global Food Security Strategy Country Plan for Nigeria in Abuja. “USAID invested almost $200 million in agriculture over the last five years to improve food security and build…

Roundtables – How China Got Ahead on EVs

How China Got Ahead on EVs Speakers: Zeyi Yang, China reporter, Amanda Silverman, Features & investigations editor, and Abby Ivory-Ganja, Sr engagement editor In the race to produce and sell more electric vehicles, China has emerged as the unexpected winner. If you visit Shanghai or Shenzhen today, it feels like half of the cars running on the streets are electric. The burgeoning domestic demand also transformed Chinese auto companies into aggressive challengers in the global auto market. What did China’s government…

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…

The EPA reveals final auto industry regulations to try to keep the world habitable

The Environmental Protection Agency (EPA) unveiled its final pollution emissions standards for the auto industry on Wednesday. The regulations, which include a looser timeframe than those proposed last year, mandate that by 2032, most new passenger car and light truck sales in the US must be electric or hybrid.Earth is on a disastrous trajectory with climate change, and no amount of baseless conspiracy theories or talking points from the oil and gas industry, Donald Trump or anyone else will change that. Only phasing out…

Unveiling the Silent Crisis Beneath America’s East Coast

2007 – 2020Critical infrastructure is threatened as sinking land amplifies global sea level rise.In many parts of the U.S. East Coast, rising seas driven by melting ice and the thermal expansion of warming water is only part of what threatens coastal areas. The land is also sinking. This geologic two-step is happening rapidly enough to threaten infrastructure, farmland, and wetlands that tens of millions of people along the coast rely upon, according to a NASA-funded team of scientists at Virginia Tech’s Earth Observation…

Unraveling the Arctic’s Surprising Rain Surge

The Arctic and North Atlantic oceans have seen an increasing number of days when precipitation falls as rain, not snow.The Arctic is known for its cold temperatures, which allow precipitation to fall as snow. But as temperatures warm, that snow is being replaced by rain. These changes can affect sea ice in the Arctic and weather patterns throughout the Northern Hemisphere.NASA scientists examined rainfall trends over the Arctic and North Atlantic oceans from 1980 to 2016 and found an increase in the frequency of rainy…

Melting Mysteries Unlocked at Greenland’s Grounding Zones

Petermann Glacier drains about 4 percent of the Greenland Ice Sheet as it moves inexorably toward the Arctic Ocean. A new observation and modeling study shows that the glacier is more vulnerable than previously thought to the intrusion of warm ocean water on its underside, leading to accelerated melting and boosting the potential severity of future sea level rise. Credit: Eric Rignot / UCIUC Irvine researchers suggest we may be underestimating the severity of sea level rise.Researchers at the University of California,…

Navigating the Oil Dilemma To Meet 1.5°C Goals

The study presents the atlas of unburnable oil in the world, designed based on environmental and social criteria to reduce CO₂ emissions in the atmosphere, combat the effects of climate change and comply with this international treaty, signed in 2015 in Paris as part of the UN Climate Change Conference (COP21).

Credit: Stan Lim / UCRIn the process of converting plants into fuel, the initial phase — decomposing the plant material — has consistently posed the greatest challenge. Recent research reveals that incorporating an easily renewable chemical during the pretreatment phase could, at last, render the production of advanced biofuels economically viable and carbon neutral.For biofuels to compete with petroleum, biorefinery…
