There is no time to lose

Carbon dioxide levels continue at record levels, despite COVID-19 lockdown, the WMO reports. The increase in carbon dioxide from 2018 to 2019 was larger than that observed from 2017 to 2018 and larger than the average annual growth rate over…

A rich source of nutrients under the Earth’s ice sheets

Trace elements such as iron and zinc are essential micronutrients for all kinds of organisms. Below ice sheets, which cover around ten percent of the Earth’s land surface, larger quantities of these substances are mobilised than previously assumed. This is shown by new data from Greenland and Antarctica, which were collected and analysed by an international research team.

Cloud Seeding: Does It Prevent Global Warming or Worsens It? – Science Times

Cloud seeding has been used in many countries to enhance precipitation, dissipate fog, and modify hurricanes. It can be done by humans and can also occur naturally. But this method is controversial for many reasons. Clouds protect the planet by reflecting…

Depressing Study Shows a Big Issue With Using Cloud Seeding to Solve Global Warming – ScienceAlert

The clouds that hang low and thick in our sky, reflecting sunlight back out into space, are melting into thin air as the world warms. The loss will not only trigger greater climate changes than we expected, but new research…

Metal deposits from Chinese coal plants end up in the Pacific Ocean, USC research shows

(University of Southern California) Emissions from coal-fired power plants in China are fertilizing the North Pacific Ocean with a metal nutrient important for marine life, according to new findings from a USC-led research team. The researchers believe these metals could change the ocean ecosystem, though it’s unclear whether it would be for better or worse.

UCI, others see agriculture as major source of increase in atmospheric nitrous oxide

(University of California – Irvine) In a new study in Nature, climate researchers have drawn the clearest lines yet around the problem of nitrous oxide in Earth’s atmosphere. The potent greenhouse gas has both natural and human sources and, compared to CO2, is difficult to remove from the air, where it ‘lives’ for about 116 years.

How to stop global warming? The most controversial solutions explained – Eco-Business

Depending on who you ask, geoengineering is either a threat to serious climate action, a faraway back-up plan or a necessary part of today‚Äôs climate policy. All would likely agree it is contentious. Geoengineering encompasses a broad spectrum of proposed…

Lessons from a cooling climate

Usually, talk of carbon sequestration focuses on plants: forests storing carbon in the trunks of massive trees, algae blooming and sinking to the seabed, or perhaps peatlands locking carbon away for tens of thousands of years. While it’s true that plants take up large amounts of carbon from the atmosphere, the rocks themselves mediate a great deal of the carbon cycle over geological timescales. Processes like volcano eruptions, mountain building and erosion are responsible for moving carbon through Earth’s atmosphere, surface and mantle.
