đœStromboli has just erupted again for the second time this month. There has been 8000 earthquakes since January 2020 in Iceland, coinciding with a volcano network that has not been awake for 800 years.
There has been 250 small Earthquakes in Idaho, and the most recent relatively strong quake worldwide was registered in Honduras, over 6,3 magnitude, yesterday.
This is possibly part of the reasons there flocks of giant locusts ravaging Africa. Rainy periods of time like the March Rain may serve to catalyse their reproduction and they appear right when its time to harvest crops June and July, when farmers are just starting to harvest.
(Kenya, Somalia, and southern Ethiopia have the right conditions with the possibility of migrations to Uganda and South Sudan.)
Every few years, natural swings in the ocean can lead to such a warming, drastically altering weather on landâand setting the stage for flooding rains in East Africa. But at the same time, a second ocean shift was brewing. An unusually cold pool of water threatened to park itself south of Madagascar, leading to equally extreme, but opposite, weather farther south on the continent: drought.
Scientists have studied this ebb and flow for centuries, but only began understanding its effects on our planet at the dawn of the space age in the mid-20th century. Now it is clear that around solar maximum the sun is more likely to bombard Earth with charged particles that damage satellites and power grids. The solar cycle also plays a minor role in climate, as variations in irradiance can cause slight changes in average sea-surface temperatures and precipitation patterns. Thus, a better understanding of the cycleâs physical drivers is important for sustainable living on Earth.
Yet scientists still lack a model that perfectly predicts the cycleâs key details, such as the exact duration and strength of each phase. âI think the solar cycle is so stable and clear that there is something fundamental that we are missing,â says Ofer Cohen, a solar physicist at the University of Massachusetts Lowell. One obstacle to figuring it out, he says, is that crucial details of the apparent mechanisms behind the cycleâsuch as the sunâs magnetic fieldâare largely hidden from our view. But that might be about to change.
Tim Linden, an astronomer at The Ohio State University, and his colleagues recently mapped how the sunâs high-energy glow dances across its face over time. They found a potential link between these high-energy emissions, the sunâs fluctuating magnetic field and the timing of the solar cycle. This, many experts argue, could open a new window into the inner workings of our nearest, most familiar star.
Japanese researchers are closing in on understanding why electrical storms have a positive influence on the growth of some fungi. In a series of experiments, Koichi Takaki at Iwate University and colleagues showed that artificial lightning strikes do not have to directly strike shiitake mushroom cultivation beds to promote growth. Now they are developing technology to use electric stimulation in the production of the mushrooms, which are popular in many east Asian cuisines.
Bizarre as it may seem, atmospheric electricity has long been known to boost the growth of living things, including plants, insects and rats. In 1775, the priest and physicist Giovanni Battista Beccaria of the University of Turin reported, âit appears manifest that nature makes extensive use of atmospheric electricity for promoting vegetationâ.

The Philippine Sea plate is bordered by the larger Pacific and Eurasia plates and the smaller Sunda plate. The Philippine Sea plate is unusual in that its borders are nearly all zones of plate convergence. The Pacific plate is subducted into the mantle, south of Japan, beneath the Izu-Bonin and Mariana island arcs, which extend more than 3,000 km along the eastern margin of the Philippine Sea plate. This subduction zone is characterized by rapid plate convergence and high-level seismicity extending to depths of over 600 km. In spite of this extensive zone of plate convergence, the plate interface has been associated with few great (M8.0) âmegathrustâ earthquakes. This low seismic energy release is thought to result from weak coupling along the plate interface (Scholz and Campos, 1995). These convergent plate margins are also associated with unusual zones of back-arc extension (along with resulting seismic activity) that decouple the volcanic island arcs from the remainder of the Philippine Sea Plate (Karig et al., 1978; Klaus et al., 1992).
South of the Mariana arc, the Pacific plate is subducted beneath the Yap Islands along the Yap trench. The long zone of Pacific plate subduction at the eastern margin of the Philippine Sea Plate is responsible for the generation of the deep Izu-Bonin, Mariana, and Yap trenches as well as parallel chains of islands and volcanoes, typical of circum-pacific island arcs. Similarly, the northwestern margin of the Philippine Sea plate is subducting beneath the Eurasia plate along a convergent zone, extending from southern Honshu to the northeastern coast of Taiwan, manifested by the Ryukyu Islands and the Nansei-Shoto (Ryukyu) trench. The Ryukyu Subduction Zone is associated with a similar zone of back-arc extension, the Okinawa Trough. At Taiwan, the plate boundary is characterized by a zone of arc-continent collision, whereby the northern end of the Luzon island arc is colliding with the buoyant crust of the Eurasia continental margin offshore China.
NASAâs new 3-dimensional portrait of methane concentrations shows the worldâs second largest contributor to greenhouse warming, the diversity of sources on the ground, and the behavior of the gas as it moves through the atmosphere. Combining multiple data sets from emissions inventories, including fossil fuel, agricultural, biomass burning and biofuels, and simulations of wetland sources into a high-resolution computer model, researchers now have an additional tool for understanding this complex gas and its role in Earthâs carbon cycle, atmospheric composition, and climate system.
Since the Industrial Revolution, methane concentrations in the atmosphere have more than doubled. After carbon dioxide, methane is the second most influential greenhouse gas, responsible for 20 to 30% of Earthâs rising temperatures to date.
âThereâs an urgency in understanding where the sources are coming from so that we can be better prepared to mitigate methane emissions where there are opportunities to do so,â said research scientist Ben Poulter at NASAâs Goddard Space Flight Center in Greenbelt, Maryland.

Global warming is a complex problem that is not easy to solve. While world leaders seem to be dragging their feet over the issue, Yotam Ariel, founder of Bluefield, believes he might have at least one piece of the puzzle sorted. Methane monitoring from space. By leveraging a network of microsatellites with a proprietary sensor, Bluefield plans to deliver alerts and analytics to oil and gas clients to help combat the inadvertent release of methane gas
Methane, a greenhouse gas, is leaking into the atmosphere. One might ask, âWhy bother with methane, isnât carbon dioxide the problem?â Well, according to the IPCC (https://www.ipcc.ch/), methane is 84 times more potent than carbon dioxide, which is clearly a bad thing for global warming. Methane is believed to be responsible for 25% of global warming and knowing who is emitting, when, and how much, would be a massive step towards reversing climate change. Since between 50 and 65% of total global methane emissions come from human activities, being able to identify and stop leaks is crucial to lowering greenhouse gases in our atmosphere.
Bluefield plans to specialize in methane gas detection and not try and solve all problems all at once and thereby reducing complexity. Further reduction in complexity is achieved by leveraging outside suppliers where applicable that complement the Bluefield plans. By reducing the complexity, Bluefield can focus on its core mission and specialty. Areas outside of detection such as the satellite parts, ground stations, the launch, and other services will be outsourced. This will allow Bluefield to quickly move through its development stages. Whereas it might take up to 10 years for a space agency like NASA, JAXA or ESA, to fund, design, test and launch a custom satellite, Bluefield aims to accomplish this as early as next year.
In fact, the prototype for the first microsatellite design has already been completed. Bluefield shortlisted several suppliers and the final selection will be made soon. The company is well on its way to testing its technology in orbit after completing both field tests and high-altitude balloon tests this year. By mounting its newly developed sensor on several backpack-sized microsatellites, Bluefield will be able to collect enough raw data to provide methane emission monitoring at a previously unthinkable level in terms of global coverage, high resolution and at a price point well below what is currently available.
This is not normal and there is another 3000 happening right now based on lightning tracker.
More than 3,000 lightning strikes, which occurred mostly during rainstorms, were recorded in central regions of the country on August 15, according to the National Observatory of Athens.
