How Shipping Affects Global Warming and Points to Geoengineering Solutions
Global warming is the increase in the average temperature of the Earth’s surface and atmosphere due to the accumulation of greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, in the air. These gases trap heat and prevent it from escaping to space, causing the planet to warm up. Human activities, especially the burning …

Risk of the hydrogen economy for atmospheric methane. Leaking hydrogen infrastructure could add to atmospheric methane levels. Increased levels of ozone from atmospheric pollution can destroy the chemical mating signal of insects and may thus contribute to global insect decline. Microbial biopesticides containing living parasites are valuable emerging crop protection technologies against insect pests, but …
Planting trees to store carbon has its limits
Planting trees to offset carbon emissions is seen as one of many strategies to deal with rising CO2 levels in the atmosphere. This ranges from a small scale, where members of the public are encouraged to plant trees, to well organised initiatives planting millions of trees. There has also been a growth in standards for …
Air pollution shown to affect crop yields
Crop production and food security go hand in hand. Farmers and researchers have long focussed on how to improve crop production, looking for gains to be made from better soil preparation, fertilizers, irrigation, pest control and selecting more productive cultivars. However, there are factors outside of their control, such as weather and air pollution. Air …
Could we run out of sand?
Sand can be found everywhere there is land. For anyone who has walked on a beach or visited a desert, the supply of sand seems endless. Sand can also be found at the bottom of rivers, lakes and oceans. Sand comes from rocks eroded by weathering and mechanical abrasion and the sand we see has …

Carbon capture by converting CO2 to solid carbon – a new method
Researchers in Australia have developed a new way to capture CO2 and convert it to solid carbon. The process has been developed in the laboratory and the next step will be to test it with a small prototype. It has the potential to provide a novel way to capture and store CO2. Current approaches to …

Non-target pesticide impact on human health and development.
Charles Taylor, a PhD candidate at Columbia University, used long term data on pesticide use in apple orchards corresponding to the emergence of cicadas in 13 and 17 year cycles in the eastern United States to identify off-farm impacts. His study reports adverse effects on infant mortality and health, and poorer school outcomes.
New method to produce cement with huge reduction in CO2 emissions
Concrete is an incredibly useful and versatile material. It is made from sand, gravel, water and cement, and can be cast into different shapes, becoming very hard as it sets. It is one of the most commonly used substances in the construction industry. Unfortunately, cement production is a significant contributor to greenhouse gas (GHG) emissions. …
