New study identifies mosquitoes' favorite colors to feast on

While many of us look forward to the warmth spring brings each year, there’s another aspect of the hotter seasons that is not so exciting—pesky mosquitoes! This is especially true for those individuals out there whom mosquitoes find the tastiest (you know who you are) and always end up with Read More...

New platform CTrees calculates the carbon in every tree on Earth

New startup CTrees uses artificial intelligence to track exactly how much CO2 the world’s three trillion trees are storing, thereby determining the extent to which trees are helping the planet. CTrees, which was developed by a team of NASA scientists, has a very simple motto: “see the forest Read More...

Ocean carbon capture

This system takes CO2 from the air by taking it from the sea

The world over, researchers and scientists are looking for effective and economical ways to pull CO2 out of the air to mitigate the effects of climate change. There are many promising solutions out there, but the amount of CO2 that needs to be withdrawn is substantial and the process of pulling it Read More...

Liquid metal turns CO2 emissions into solid carbon at the source

Capturing carbon dioxide before it reaches the atmosphere is a key part of our global strategy to combat climate change. In an effort to find ways that could help us do that efficiently, scientists at RMIT have developed a method that quickly converts carbon dioxide into solid carbon, which can Read More...

Ukraine plans to plant one billion trees over the next three years

Back in 2019, Swiss scientists conducted a study that concluded that the most effective way to combat climate change is to plant a trillion trees. According to the study’s calculations, planting at least one trillion trees could sequester nearly 830 billion tons of heat-trapping carbon dioxide Read More...

Researchers propose using passenger car emissions in agriculture

The average passenger emits about five US tons of CO2 and 5,547 gallons of waste water each year, while urban farmers use almost five pounds of CO2 and six gallons of water to grow two pounds of produce. Researchers from Texas A&M University believe these two systems could be combined to Read More...

‘Nanojars’ can help remove CO2 and other major pollutants from water

While the most common environmental concern regarding carbon dioxide has to do with its greenhouse effects in the atmosphere, a lot of it actually ends up in our oceans, making them more acidic. In a bid to find a solution to this problem, researchers have recently developed “nanojars” that can Read More...

Zelp makes methane-reducing masks for cows

We at The Optimist Daily have written extensively about the numerous ways in which the beef and dairy industry can clean up their act with solutions like seaweed-supplemented feeds and plant-based food alternatives. These days, veganism and vegetarianism are gaining more popularity as we become Read More...

Study: Electricity-eating bacteria could help fight climate change

From spreading crushed rocks in forests and farmlands to constructing green buildings with materials that suck carbon up out of the atmosphere, scientists are hard at work developing innovative solutions that reduce our greenhouse gas emissions. More recently, a team of scientists from Washington Read More...

South Korea to plant 3 billion trees to achieve net-zero emissions by 2050

In recent years, scientists have increasingly highlighted the key role that reforestation can play in fighting climate change. This has given rise to numerous initiatives around the world that have made it their goal to reduce CO2 emissions in the atmosphere by planting trees. Among these is the Read More...
