The most ambitious proposal for carbon removal involves fertilizing the ocean with iron sulfate and other nutrients to stimulate algae growth that could potentially revitalize the marine food chain while also absorbing atmospheric carbon. In terms of slowing global warming, injecting sulphur dioxide aerosol particles in the atmosphere would reflect sunlight and cool temperatures across the globe.

Extremely busy hurricane season 2020 now taps into the Greek alphabet
https://www.severe-weather.eu/tropical-weather/greek-alphabet-atlantic-hurricanes-mk/

There are still several months left until the official end of hurricane season 2020, but there has already been twice the average number of storms. With 23 storms under the belt, the traditional hurricane names are used. We are moving into the Greek alphabet. Alpha and Beta formed on Friday, but more is on the way!

What makes this season being so extreme and record-breaking, is the fact that storms with the same letters are developing weeks earlier than normally expected. And even much earlier than previously set records.

Such satellite image of numerous active storms is almost typical for 2020. While there was very active Tropical Atlantic not enough, even the Mediterranean produced a tropical storm – Medicane Ianos!

...

the temperatures are around 1-2 degrees Celsius warmer than the long-term average (1981-2010) across the Western Atlantic, Caribbean, and also in part of the Gulf. Seas are particularly warm along the US East Coast, even up to 3 °C warmer.

'Shocking': wilderness the size of Mexico lost worldwide in just 13 years, study finds | Environment | The Guardian

Wilderness across the planet is disappearing on a huge scale, according to a new study that found human activities had converted an area the size of Mexico from virtually intact natural landscapes to heavily modified ones in just 13 years.

The loss of 1.9m square kilometres (735,000 sq miles) of intact ecosystems would have “profound implications” for the planet’s biodiversity, the study’s authors said.

Using mostly satellite imagery, 17 scientists across six countries examined the human footprint across the globe and how it had changed between 2000 and 2013.

Almost 20% of the earth’s surface had deteriorated, the study found, while human pressure had eased on only six per cent of the planet.

Russia, Canada, Brazil, and Australia held the largest intact areas, together responsible for 60% of the world’s most untouched places.

Some 1.1m sq km (425,000 sq miles) of wilderness identified from imagery in 2000 had some human impact 13 years later.

Tropical savannahs and grasslands lost the most area to human pressure, the study, published in the journal One Earth, found.

Energy Flow Trends in Big History | SpringerLink

Energy flow is a major necessary component driving evolution of living system (along with information processes, organization, and entropy management). Energy flow is defined as the rate of energy use, after thermal heat losses are considered, i.e., free-energy power. Chaisson identified the energy flow density as a major determinant of complexity. Energy (such as food) is used to restore order among living systems (cell, animal, person, and civilization) overcoming the natural tendency to decay and diffuse. New energy mechanisms have been identified through the evolution of life, humans, and civilizations. The rate of energy innovation events is the same hyperbolic trend (with a singularity) that is seen in formation of new organizations. Here, we also investigate estimates of the energy flowing through evolving systems from early hydrothermal vents to the current global situation. It is found that the energy flow increases a bit faster than the population (or mass) in the system. For example, human bodies (such as early humans) use about 100 W of energy flow, whereas the global average is now roughly 3000 W per person with wide disparity (e.g., 10000 W/capita in the USA and 1000 W/capita in India).

2019 On the Circular Bioeconomy and Decoupling: Implications for Sustainable Growth
https://www.sciencedirect.com/science/article/pii/S0921800918317178

This paper explores the existing confusion around the conceptual definitions and interpretations of the term circular bioeconomy. The co-existence of diametrically opposite interpretations of the concept indicates lack of a serious discussion of its theoretical foundations. Two narratives on circular bioeconomy are explored in depth: (i) the new economic paradigm based on technological progress (the economics of technological promises) that seeks perpetual economic growth; (ii) an entropic (thermodynamic) narrative that reflects on the limits on economic growth imposed by nature. The latter narrative makes a distinction between primary, secondary and tertiary resource flows and helps to identify what can and cannot be re-circulated within the metabolic pattern of social-ecological systems. Adopting the biophysical view, it becomes clear that the industrial revolution represented a linearization of material and energy flows with the goal to overcome the low pace and density of biological transformations. The required level of productivity of production factors in contemporary developed economies (flows per hour of labor and per hectare of land use) is orders of magnitude larger than the pace and density of supply and sink capacity of natural processes. Relying on nature to ‘close the loop’ will simply slow down the economic process.
