Comments Off on Earth has lost 14% of its coral reefs in less than a decade

A  new report  released by the Global Coral Reef Monitoring Network found that up to 14% of the world’s coral reefs have been depleted due to climate change between the years 2009 and 2018. In the period under review, mass coral bleaching events were experienced due to warming waters. The study is the largest done to review the status of corals across the world. It included observation of reefs in more than 70 countries over the past 40 years. The research found that the highly sensitive reefs were exposed to tough conditions due to climate change, including high temperatures and tsunamis. Tough weather patterns are said to have contributed to the depletion of the essential reefs. Related: Global warming driving mass migration of marine life The study estimates that the loss amounts to over 4,500 square miles of reefs lost in just nine years. This is more than all the living coral off the coast of Australia including the great barrier reef . The loss of corals is likely to continue since the world is on an upward warming trend, according to Paul Hardisty, head of the Australian Institute of Marine Science. “There are clearly unsettling trends toward coral loss, and we can expect these to continue as warming persists,” Hardisty said. “A clear message from the study is that climate change is the biggest threat to the world’s reefs, and we must all do our part by urgently curbing global greenhouse gas emissions and mitigating local pressures.” The value that coral reefs add to the ecosystem can never be overstated. Although they make up 0.2% of the ocean floor, they account for over 25% of the ocean system’s biodiversity . Coral reefs provide approximately $2.7 trillion in value per year, according to the report. Tourism contributes about $36 billion of this amount. With such a huge economic impact, coral reefs are just as important as other economic activities in the modern age. The good news is that, although coral reefs are vulnerable to climate change, they are still resilient. The report found that the reefs were facing the fight against warming waters. However, the researchers warn that the situation might soon change. With carbon emissions still on the rise, chances are the corals may not survive the high temperatures .

Comments Off on Maritime shipping projected to triple by 2050. How will the industry decarbonize?

Ships carry around 90 percent of goods transported globally, and the shipping sector accounts for about 3 percent of the world’s greenhouse gas emissions today. But maritime trade volumes are projected to triple by 2050.

Cities are the engines of modern economic activity — generating 85 percent of today’s GDP. But this comes at a cost: urban communities consume 75 percent of the world’s natural resources, generate half of all global waste, and create two-thirds of the world’s greenhouse gas emissions.

Energy-generating ‘artificial plants’ turn greenhouse gases into clean air

Comments Off on Energy-generating ‘artificial plants’ turn greenhouse gases into clean air

Groundbreaking research from scientists at the University of Central Florida (UCF) and Florida State University could help in the fight against climate change . The researchers were able to trigger photosynthesis in metal-organic frameworks (MOF) with a little help from blue light , and the process turned carbon dioxide (CO2) into solar fuel . UCF assistant professor Fernando Uribe-Romo described the find as a breakthrough. Scientists have been seeking such a breakthrough for years. The trick is getting visible light to set off the chemical reaction; ultraviolet rays can do it but only comprise four percent of the light hitting Earth from the sun. Most materials that can absorb visible light to set off the reaction are too expensive or rare. The Florida scientists, however, found they could use the common nontoxic metal titanium added with organic molecules that can be designed to absorb certain colors of light. Uribe-Romo set them up to absorb blue light. Related: MIT Scientists Create Artificial Solar Leaf That Can Power Homes The team tested the MOF inside a photoreactor – or glowing blue cylinder lined with LED lights to mimic blue wavelengths shining from the sun – and the resulting chemical reaction turned CO2 into solar fuel. Uribe-Romo said, “The idea would be to set up stations that capture large amounts of CO2, like next to a power plant . The gas would be sucked into the station, go through the process, and recycle the greenhouse gases while producing energy that would be put back into the power plant.” He said it may even be possible for the material to be put in rooftop shingles to both clean the air and generate energy usable for homeowners. He aims to keep working with the synthetic material and see if different wavelengths of visible light can set off the reaction. The Journal of Materials Chemistry A published the find online earlier this month. Via The Independent and EurekAlert! Images via UCF: Bernard Wilchusky and University of Central Florida

The electricity industry historically has played the biggest role in the U.S. greenhouse gas emissions problem. It has an even greater potential to be an even bigger part of the solution, but its leaders must speak up.
