President Obama has pushed through the first installment of a pledged $3 billion from the cabinet to help poor countries fight climate change.

The first chunk of change went to the Green Climate Fund, an international body created to assist developing countries adapt to and mitigate climate change.

The effects of climate change often hit the world’s poor the hardest. Millions of the poorest families around the world are farmers, suffering from the devastating effects of harmful emissions affecting local climates. This could sink those families even deeper into poverty, yet they are typically the ones least at fault for the rising levels of emissions such as carbon dioxide.

The $500 million is part of President Obama’s Clean Power Plan, which is aimed at cutting U.S. carbon emissions in order to fight climate change. The first transaction shows that the cabinet is committed to delivering on its pledge made at the United Nations’ climate change conference in Paris in late 2014.

“The United States provided a $500 million grant to the Green Climate Fund,” a State Department official said. “This grant is the first step toward meeting the president’s commitment of $3 billion to the GCF, and shows that the United States stands squarely behind our international climate commitments.”

Not only does this payment help enact measures to fight climate change, President Obama also hopes it will act as a signal to the national and international community after the supreme court block a major piece of the cabinet’s climate plan last month.

Globally, carbon dioxide is the number one contributor to harmful greenhouse gas emissions. These emissions accelerate climate change, leading to such devastating effects as rising sea levels that can dislocate families and radical local climates that hurt food production levels.

But what if we could turn those harmful emissions into useable fuels through a simple, one-step process?

Researchers have proven that through a process combining concentrated light, heat, and high pressure, carbon dioxide and water could be directly converted into usable liquid hydrocarbon fuels.

Not only would this effort offer some relief in the energy infrastructure, it would also aid efforts against climate change by removing carbon dioxide from the atmosphere.

“Our process also has an important advantage over battery or gaseous-hydrogen powered vehicle technologies as many of the hydrocarbon products from our reaction are exactly what we use in cars, trucks and planes, so there would be no need to change the current fuel distribution system,“ said Frederick MacDonnell, co-principal investigator of the project.

The corresponding paper was published in the Proceedings of the National Academy of Sciences.

“We are the first to use both light and heat to synthesize liquid hydrocarbons in a single stage reactor from carbon dioxide and water,” said Brian Dennis, co-principal investigator of the project. “Concentrated light drives the photochemical reaction, which generates high-energy intermediates and heat to drive thermochemical carbon-chain-forming reactions, thus producing hydrocarbons in a single-step process.”

In order to meet increasing water demands and combat the devastating effects of climate change, the United Arab Emirates (UAE) is looking toward scientific innovation to help quench the Persian Gulf’s thirst.

Increasing water shortage in UAE

The first issue that leads to UAE water shortages is the essentially non-existent rainfall paired with the country’s high water consumption. The UAE’s capital of Abu Dhabi receives only 75mm of rainfall annually, with the country as a whole receiving less than 100mm of rainfall each year . Pair that with a water consumption that is the highest in the world, coming in at 82 percent above global average, and the situation starts to look serous.

But that’s not the only issue in the UAE’s water supply problems. Climate change is making this land even hotter and drier than ever before, with a study stating that the effects of climate change may make the Persian Gulf uninhabitable by 2071.

For this reason, the UAE is turning toward German and Japanese researchers, offering a $5 million reward to researchers who could help solve this problem.

The Earth is getting warmer and greenhouse gas emissions are on the rise. With carbon dioxide levels at their highest in 650,000 years, scientists across the global are grappling with the question of how to stop global warming.

For many, alternative energy sources are the answer. While the implementation of this technology is crucial for the development of a carbon-free society, flipping the grid is easier said than done. The U.S. alone is highly dependent on fossil fuels, which emit high level of greenhouse gases. Additionally, transitioning the grid to 100 percent renewables would not fully solve the issue. Emissions will still exist in the atmosphere, with warming happening right now.

“When people emerge from poverty and move toward prosperity, they consume more energy,” said Adam Heller in a recent plenary lecture.

The Need for a Solution

Currently, 13 percent of carbon dioxide emissions stem from two industries: steel and cement. According to Heller, these industry are directly correlated to global wealth—what he deems the driving force of acceleration in climate change. To put that in perspective, the solar energy technology that is currently in place in the U.S. saves only 0.3 percent through the use of solar energy, according to Heller. With carbon dioxide emissions constantly accelerating, increasing by 2 percent every year, scientists are looking for solutions to this pressing issue.

“This will lead to a catastrophe,” Heller said. “The question is, what do we do about this catastrophe?”

For Heller and other scientists, part of the answer lies in solar geoengineering (SGE).

“We need to learn something about geoengineering,” Heller said. “We need to learn something about reflecting light from the sun through aerosols in the atmosphere.”

In light of U.N. Climate Talks in Paris and the crippling air pollution levels in China, Bill Nye continuing the good fight against climate change with his latest pitch for a solution against the catastrophic force.

His possible solution? Bubbles.

Through a simple experiment, Nye explores the possibility of purposely inducing bubbles to potentially help satisfy water and sanitation demands as well as reflect light into space—helping control the global temperature.

In the full interview with Yahoo! News Live, Nye also discusses a carbon fee, the real threats of climate change, and “climate deniers.” Check out the full video.

The effort to harvest atmospheric carbons and transform the greenhouse gases into renewable fuels has taken one step closer to practicality due to new research out of Monash University.

Through the novel combination of cheap materials to develop an energy efficient catalyst, the researchers believe they could electrochemically reduce carbon dioxide into syngas. This produced syngas would be comprised of a combination of carbon monoxide and hydrogen—the elements widely used as the starting point to produce sustainable fuels and materials.

“Our research found that a combination of cheap materials—Molybdenum Sulphide catalytic nano-particles with a conductive layer of graphene and a well-known polymer called polyethylenimine acted together to create this energy efficient catalyst. Each component in the catalyst played a specific role in the reaction and it was only when the three were combined that the energy efficiency of the process was realized,” said Jie Zhang, lead author of the study.

In a practical effort to address climate change, researchers are looking at the possibility to capture harmful greenhouse gasses and transforming them into something useful for society. Recently, researchers from the University of South Carolina started exploring this topic, opening the door for more research in green fuels produced by carbon. Now, a team from the University of South Australia is taking that concept and applying nanoporous carbon nitride to help solve global warming.

With carbon dioxide levels at their highest in 650,000 years, scientists are developing innovative ways to help contain the greenhouse gas. The team at the University of South Australia, led by Ajayan Vinu, is working to capture and convert carbon dioxide molecules with the help of nanoporous materials.

“Their interesting properties—a semiconducting framework structure and ordered pores—make them exciting candidates for the capture and conversion of [carbon dioxide] molecules into methanol which can then be used as a source of green energy with the help of sunlight and water,” Vinu said.

Today kicked off the fifth international ECS Electrochemical Energy Summit. ECS President Dan Scherson opened the summit by welcoming attendees and putting these critical topics in renewable energy into perspective.

“The research you are doing directly addresses some of the major issues people are facing around the world,” says Scherson. “Our work is about the sustainability of the planet.”

Since its establishment in Boston in 2011, the summit has grown substantially in magnitude. This year, the keynote speaker was Franklin Orr, U.S. Under Secretary for Science and Energy. Among his many responsibilities, Orr oversees the Department of Energy’s (DOE) offices of Energy Efficiency and Renewable Energy, as well as the office of Electricity Delivery and Energy Reliability.

The Future of Renewable Energy

“We’re really looking for a cost effective energy system, security for energy resources, and—even more importantly now than it was a few years ago—the environmental security,” says Orr.

Orr discussed the Quadrennial Technology Review, a recently published work by the DOE. Focusing on the energy infrastructure of the United States, the report seeks to find ways to modernize and make more secure the energy infrastructure.

Do your old, damp coffee grounds have the potential to save the world? New research from the journal Nanotechnology states that the same coffee grounds you toss in the trash every day actually have the ability to store methane.

ECS Fellow Meyya Meyyappan and a team of researchers found that by combining the used coffee grounds with potassium hydroxide, a material with the ability to store substantial amounts of methane was created.

Coffee Grounds Fight Climate Change

In light of global warming and the damaging effects rising temperatures and increased greenhouse gas emissions have on the planet, the ability to store harmful methane is critical.

Methane is a preventable greenhouse gas that accounts for about 10 percent of all harmful emissions derived from human activity. While methane doesn’t stay in the atmosphere as long as the more commonly talked about carbon dioxide, it is far more devastating to the climate due to its extreme efficiency in absorbing heat. In fact, methane is about 84 times more potent than carbon dioxide.

The science behind climate change is alarming. Concentrations of greenhouse gases are rising at an alarming rate, land ice is dropping by 258 billion metric tons per year, and every passing year is proving to be the warmest year on record. Even with all of this information, it is difficult for some to grasp the complications climate change is causing due to the fact that an average person’s day-to-day life has remained relatively unharmed.

“You can tell people that all these fossil fuels we’re using and all the CO₂ that’s building up in the air is going to cause terrific problems. It’s only going to be when lower Manhattan is underwater that they’re going to start to respond,” said Allen J. Bard, the unofficial father of modern electrochemistry.

What Does Climate Change Look Like?

In order to make the reality of climate change more tangible, scientists with the Department of Energy are launching their SPRUCE (Spruce and Peatland Responses Under Climatic and Environmental Change) project to naturally demonstrate what the world could look like if there is no action taken on climate change.
