Numerous prominent petroleum geologists have been warning for years about the resources limitations of oil both in the U.S. and globally. It’s now looking like the wolf is nearing the door.
Exclusive: Meeting took place days after BP reported record profits while households were squeezed by high energy bills
Energy firms have made record profits by increasing production of oil and gas, far from their promises of rolling back emissions
Microplastic pollution reduces energy production in a microscopic creature found in freshwater worldwide, new research shows. Paramecium bursaria contain algae that live inside their cells and provide energy by photosynthesis. The results of a NEW STUDY showed a 50% decline in net photosynthesis—a major impact on the algae's ability to produce energy and release oxygen
Atmospheric soot loadings from nuclear weapon detonation would cause disruptions to the Earth’s climate, limiting terrestrial and aquatic food production. Here, we use climate, crop and fishery models to estimate the impacts arising from six scenarios of stratospheric soot injection, predicting the total food calories available in each nation post-war after stored food is consumed. In quantifying impacts away from target areas, we demonstrate that soot injections larger than 5 Tg would lead to mass food shortages, and livestock and aquatic food production would be unable to compensate for reduced crop output, in almost all countries. Adaptation measures such as food waste reduction would have limited impact on increasing available calories. We estimate more than 2 billion people could die from nuclear war between India and Pakistan, and more than 5 billion could die from a war between the United States and Russia—underlining the importance of global cooperation in preventing nuclear war.
Exclusive: Nearly half existing facilities will need to close prematurely to limit heating to 1.5C, scientists say
Later this year, Egyptian engineering firm Arab Contractors is expected to complete the construction of the Julius Nyerere dam on the Rufiji River. Once completed, the $3 billion dam could be Africa’s fourth biggest by power production, producing up to 5920GWH of power annually, enabling Tanzania to close the gap between those with electricity and those who have no access.
In this 2nd part we use data from the BP Statistical Review (June 2020). BP’s definition of oil is different from OPEC’s crude oil used in part 1. It includes also shale oil, oil sands, condensates (lease condensate or gas condensates that require further refining) and NGLs (natural gas liquids – ethane, LPG and naphtha separated from the production of natural gas).
The fossil fuel production gap — the difference between global fossil fuel production projected by governments’ plans (red line) and those consistent with 1.5°C- and 2°C-warming pathways (blue and green lines), as expressed in carbon dioxide (CO2) emissions released when the extracted fuels are burned — remains large.
The fundamental assumption underlying these beliefs is that economic growth can be “decoupled” from resource and ecological demands and impacts. That is, it is claimed that the rate of production and consumption can continue to increase while the resources needed to do this can be reduced to sustainable levels, along with the environmental damage it causes. It is disturbing that this tech-fix faith persists despite the mountain of evidence that it is wrong.
The case for cutting meat consumption is so compelling that you would think politicians would be less shy about making it. Yet while campaigners warn with increasing urgency that global livestock production is accelerating climate breakdown and causing devastating damage to nature and human health, governments remain reluctant to tackle meat-eating.
Energy transition and peak demand predictions have spooked investors in oil, putting the prospect of peak production sooner than anticipated accompanied by wild price spikes.
At least eight types of bird flu, all of which can kill humans, are circulating around the world’s factory farms – and they could be worse than Covid-19
U.S. energy producers have cut so deeply into a once-large reserve of oil wells waiting to be turned on they soon may have to resume drilling to keep production from sagging, executives and analysts said.
Since the turn of the millennium, the world has been losing around 5 million hectares of forest every year. Nearly all of this occurs in the tropics; almost half of all deforestation takes place in Brazil and Indonesia. Three-quarters is driven by agriculture. Beef production is responsible for 41% of deforestation; palm oil and soybeans account for another 18%; and logging for paper and wood across the tropics, another 13%. These industries are also dominant in a few key countries.
While the element phosphorus is not scarce in the earth’s upper crust, the amount that can be accessed for productive use in food production is orders of magnitude smaller due to a wide range of bottlenecks including physical, economic, technical, geopolitical, legal, ecological and environmental constraints. From a food security and sustainability perspective, the most important quantity is not the total amount of phosphate rock in the ground but the fraction that is available to be accessed by farmers and applied to agricultural fields for food production.
the sediments below oxygen-depleted waters are a significant source of nitrous oxide (N2O). This gas is released into the atmosphere when deep water rises to the surface in a process known as upwelling. Nitrous oxide, more commonly known as “laughing gas,” is a potent greenhouse gas, 300 times more powerful than carbon dioxide. Global emissions of N2O are increasing as a result of human activities that stimulate its production.
The world’s five largest publicly traded oil companies are increasing their investments in oil and gas, putting a combined $110 billion in new fossil-fuel production. Meanwhile, those firms are projected to spend just $3.6 billion on low-carbon investments, such as biofuels and renewables, according to a new analysis that Influence Map
