What’s in a flame? The surprising mystery of how soot forms

Soot is one of the world’s worst contributors to climate change. Its impact is similar to global methane emissions and is second only to carbon dioxide in its destructive potential. This is because soot particles absorb solar radiation, which heats the surrounding atmosphere, resulting in warmer global temperatures. Soot also causes several other environmental and health problems including making us more susceptible to respiratory viruses.

Soot only persists in the atmosphere for a few weeks, suggesting that if these emissions could be stopped then the air could rapidly clear. This has recently been demonstrated during recent lockdowns, with some major cities reporting clear skies after industrial emissions stopped.

But is also part of our future. Soot can be converted into the useful carbon black product through thermal treatment to remove any harmful components. Carbon blacks are critical ingredients in batteries, tires and paint. If these carbons are made small enough they can even be made to fluoresce and have been used for tagging , in catalysts and even in solar cells.

Weather Warfare: Weather Modification Technology in Warfare

As the world becoming aware of the environment’s brittleness, more diversified and complex ways have been devised to modify it as a weapon of warfare. Now a new class of weapons more disastrous than nuclear warfare is on the horizon. For altering the environment, weather and climate modification technologies, are the methods that may be used to convert climate and weather systems into weapons of war. It refers to Operation Popeye, which aimed to extend the monsoon season in Southeast Asia.

Captain Orville had cautioned that “if an enemy nation solves the problem of weather control and gets into the position of controlling large-scale weather patterns before we can, the effects might be even more devastating than nuclear conflict”. In this article, we have discussed in-depth Weather Modification Technology in Warfare, and how this method of modern warfare can be used to destroy any country economically, Tactically, Strategically, and Covertly.

Volcanic Eruptions Contributed To The Collapse Of Chinese Dynasties

Volcanic eruptions contributed to the collapse of dynasties in China in the last 2,000 years by temporarily cooling the climate and affecting agriculture, according to a news release by Rutgers University.

In a study published in the journal Communications Earth & Environment, scientists reconstructed the magnitude of 156 explosive volcanic eruptions from 1 A.D. to 1915 by examining elevated sulfate levels in ice cores from Greenland and Antarctica. They also analyzed historical documents from China on 68 dynasties and examined warfare there between 850 and 1911.

Scientists found that smaller volcanic “shocks” to the climate may cause dynasties to collapse when political and socioeconomic stress is already high. Larger shocks may lead to collapses without substantial pre-existing stress. Other factors include poor leadership, administrative corruption and demographic pressures.

NVIDIA to Build Earth-2 Supercomputer to See Our Future

NVIDIA plans to build the world’s most powerful AI supercomputer dedicated to predicting climate change, named Earth-2.

The earth is warming. The past seven years are on track to be the seven warmest on record. The emissions of greenhouse gases from human activities are responsible for approximately 1.1°C of average warming since the period 1850–1900.

What we’re experiencing is very different from the global average. We experience extreme weather — historic droughts, unprecedented heatwaves, intense hurricanes, violent storms and catastrophic floods. Climate disasters are the new norm.

We need to confront climate change now. Yet, we won’t feel the impact of our efforts for decades. It’s hard to mobilize action for something so far in the future. But we must know our future today — see it and feel it — so we can act with urgency.

How We’ll Control The Weather In 100 Years

Climate change can cause dramatic shifts in global temperatures and weather patterns. And while scientists won’t be able to reverse all of the negative impacts of these changes, they are looking for ways to lessen the effects by controlling the weather.

A 75-Foot Vessel Is Being Converted to Run Almost Entirely on Ammonia

Green energy company Fortescue Future Industries (FFI) is collaborating with MMA Offshore to convert a 75-meter (246-feet) vessel, the “MMA Leveque”, so that it can run almost entirely on green ammonia by 2022, a press statement from FFI explains.

In the same statement, the company reveals that its chairman, billionaire Andrew Forrest, called for an industry-wide push for shipping to reach net-zero by 2040 during a keynote for ‘Transport Day’ at the COP26 conference in Glasgow this week, a United Nations summit aimed at accelerating action on climate change.

The MMA Leveque is one of several Fortescue Metal Group’s vessels and vehicles that will be transformed to operate on green fuels, as the company also says it is gradually working on converting its fleet of trucks, locomotives, and ships. Earlier this year, FFI successfully demonstrated the combustion of a blended ammonia fuel in a locomotive, and it says it will soon be able to power trains on one hundred percent green ammonia.
