As carbon dioxide continues to build up in the Earth’s atmosphere, research teams around the world have spent years seeking ways to remove the gas efficiently from the air. Meanwhile, the world’s number one “sink” for carbon dioxide from the atmosphere is the ocean, which soaks up some 30 to 40 percent of all of the gas produced by human activities.

Recently, the possibility of removing carbon dioxide directly from ocean water has emerged as another promising possibility for mitigating CO2 emissions, one that could potentially someday even lead to overall net negative emissions. But, like air capture systems, the idea has not yet led to any widespread use, though there are a few companies attempting to enter this area.

Now, a team of researchers at MIT says they may have found the key to a truly efficient and inexpensive removal mechanism. The findings were reported this week in the journal Energy and Environmental Science, in a

Hello everybody,

I created this community to give everybody a breath of fresh air in the face of apocalyptic headline after apocalyptic headline. We face serious trouble as a species, but unless we focus our time and energy on solutions, we won't be able to get ourselves out of it. I am certain you feel the same way.

And I want this community to grow, but I can't do it all on my own, and I need your help! If you are interested in finding positive solutions to climate change, and have some moderator experience, please respond and I will get in contact with you.

Have a great day everyone, and remember it's always darkest before the dawn. 🙂

🤔 I legitimately do wonder why stuff like this and support for nuclear energy in general hasn't skyrocketed on account of climate change. It's the one large-scale means that we have to achieve clean energy with current technology, yet I see no governments pushing to replace coal plants with nuclear ones. You'd think the companies who own the coal plants would just accept the writing on the wall and switch to nuclear, if only to save themselves.

There's so much about humanity's tepid response to climate change in general that does not make sense to me, but the fact remains that nuclear is an important tool we have in our toolbox and we desperately need to start using it to prevent the real tragedy of runaway climate collapse.

What do you guys think? Do you think these small modular reactors will take off or nah?

Researchers have found that one method of reducing greenhouse gas emissions is available, affordable, and capable of being implemented right now. Nitrous oxide, a potent greenhouse gas and ozone-depleting substance, could be readily abated with existing technology applied to industrial sources.

"The urgency of climate change requires that all greenhouse gas emissions be abated as quickly as is technologically and economically feasible," said lead author Eric Davidson, a professor with the University of Maryland Center for Environmental Science. "Limiting nitrous oxide in an agricultural context is complicated, but mitigating it in industry is affordable and available right now. Here is a low-hanging fruit that we can pluck quickly."

When greenhouse gases are released into the atmosphere, they trap the heat from the sun, leading to a warming planet. In terms of emissions, nitrous oxide is third among greenhouse gases, topped only by carbon dioxide and methane. Also known as laughing g

A space solar power prototype has demonstrated its ability to wirelessly beam power through space and direct a detectable amount of energy toward Earth for the first time. The experiment proves the viability of tapping into a near-limitless supply of power in the form of energy from the sun from space.

Because solar energy in space isn’t subject to factors like day and night, obscuration by clouds, or weather on Earth, it is always available. In fact, it is estimated that space-based harvesters could potentially yield eight times more power than solar panels at any location on the surface of the globe.

The wireless power transfer was achieved by the Microwave Array for Power-transfer Low-orbit Experiment (MAPLE), an array of flexible and lightweight microwave power transmitters, which is one of the three instruments carried by the Space Solar Power Demonstrator (SSPD-1).

In Africa, scientists are hard at work restoring land once rich with biodiversity and vegetation. Eleven countries in the Sahel-Sahara region—Djibouti, Eritrea, Ethiopia, Sudan, Chad, Niger, Nigeria, Mali, Burkina Faso, Mauritania, and Senegal—have joined to combat land degradation and restore native plant life to the landscape.

In recent years, northern Africa has seen the quality of arable land decline significantly due to climate change and poor land management. Uniting under the banner of the “Great Green Wall” initiative, national and regional leaders hope to reverse this trend. The bulk of the work on the ground was originally slated to be concentrated along a stretch of land from Djibouti, Djibouti, in the east to Dakar, Senegal, in the west—an expanse 15 kilometers (nine miles) wide and 7,775 kilometers (4,831 miles) long. The project has since expanded to include countries in both northern and western Africa.

Land degradation typically stems from both human-related and natur

Marginal improvements to agricultural soils around the world would store enough carbon to keep the world within 1.5C of global heating, new research suggests.

Farming techniques that improve long-term fertility and yields can also help to store more carbon in soils but are often ignored in favour of intensive techniques using large amounts of artificial fertiliser, much of it wasted, that can increase greenhouse gas emissions.

Using better farming techniques to store 1% more carbon in about half of the world’s agricultural soils would be enough to absorb about 31 gigatonnes of carbon dioxide a year, according to new data. That amount is not far off the 32 gigatonnes gap between current planned emissions reduction globally per year and the amount of carbon that must be cut by 2030 to stay within 1.5C.

The estimates were carried out by Jacqueline McGlade, the former chief scientist at the UN environment programme and former executive director of the European Environment Agency. She fo

Gay Republicans are abandoning Florida Gov. and 2024 presidential candidate Ron DeSantis (R) in droves after his rapid response team shared a bizarre video bragging about his reign of terror against the LGBTQ+ community.

The video opens with several clips of Donald Trump – DeSantis’s top primary opponent – expressing support for LGBTQ+ people and frames these comments as damning. Most of the comments are from before he was elected president in 2016. Then, the clip abruptly shifts to intense music and a photo of DeSantis shooting lasers out of his eyes, followed by snapshots of headlines about the anti-LGBTQ+ laws DeSantis has passed.

The video proudly shares that DeSantis has been called “evil,” “dangerous,” “draconian,” and “public enemy no. 1” and even includes a clip accusing DeSantis of passing legislation “that literally threatens trans existence.” It also contains images of shirtless buff muscle men inter-spliced with these

Civil rights groups and Democrats reacted angrily to the US supreme court decision in favor of the Colorado web designer Lorie Smith, who argued she had a first amendment right to refuse to provide services for same-sex marriages. Critics of the court’s decision say it ushers in a new era of prejudice in America.

“This ruling on LGBTQ+ rights by the Maga-right activist wing of the supreme court is a giant step backward for human rights and equal protection in America,” said the Democratic Senate majority leader, Chuck Schumer, in a statement. “We will continue to fight to ensure that all Americans, including LGBTQ+ Americans, have equal protection under the law.”

The progressive Democratic congresswoman Rashida Tlaib called for term limits of justices on the conservative-dominated supreme court which has now ushered in a series of decisions rolling back well-established rights, such as overturning federal protections on abortion and affirmative action.
