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 They also analyzed historical documents from China on 68 dynasties and examined warfare there between 850 and 1911.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 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.

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.

Tech Insider tells you all you need to know about tech: gadgets, how-to’s, gaming, science, digital culture, and more.

A cold winter is spurring the hole, which will persist through November at least.

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.

The Hardware Giant NVIDIA is now working on one of the craziest projects I’ve ever seen. They’re attempting to build the fastest supercomputer ever made in hopes of simulating the entire earth in real time for climate research and potentially even more. They call this super computer Earth 2 and it’s going to feature their most powerful next generation GPU’s in the world. It’ll feature multiple exaflops of performance and be supported by the government. I can’t wait to see how this crazy project works out. It was announced by Jensen Huang at NVIDIA GTC 2021.

The same goes for the broader economy. Lower subsidies, higher taxes and pricier labour have eroded some of Saudi Arabia’s traditional selling points for firms. It is unclear what will replace them.

Until the government banned the practice, residents of Abha would chop down juniper trees for firewood, to stave off the winter chill. As part of the regional tourism project, developers plan to plant 1m trees to reforest the mountains. It will be a long time before visitors can appreciate them: they grow just 5cm a year in the region’s dry climate, says Turki al-Bishri, a local guide. For all the talk of rapid change, the slow-growing juniper may offer a better glimpse of Saudi Arabia’s economic future. ■

*To date, most studies have focused on understanding how much carbon is stored above ground (in trees and other plants, for example). This research, however, revealed that when you look below ground and get into deeper levels of soil, there are massive deposits of carbon.*

Canada’s first-ever national carbon map reveals the location of billions — yes, billions — of tonnes of carbon stored in ecosystems across the country. This data, and how we use it, could alter the pace of climate change.

With 145,000 panels.

The world’s largest floating solar farm has now begun operations at the Sirindhorn Dam on the Lam Dom Noi River in Thailand. The dam has a capacity of generating 45MW of power using its solar panels, the Electricity Generating Authority of Thailand (EGAT) confirmed in a press release.

The news comes after the country started advancing its carbon neutrality goals by 15 years. At the United Nations Climate Change Conference being held in Glasgow, UK, Thai Prime Minister Prayut Chan-o-cha pledged that his country would attain carbon neutrality by 2,050 much ahead of the earlier set target date of 2,065 local media reported. The announcement is a major move considering that two-thirds of Thailand’s current power generation is sourced from natural gas.
