Top 10 Worst Weather Disasters

https://www.seeker.com/top-10-worst-weather-disasters-1766290272.html


Curious to what was the most devastating weather disaster the Seeker list the biggest weather related disasters. With little snippets of the each events. Such as the 1925 Tri State Tornado that killed about 700 people and ripped through 3 states in 3 and a half hours. Destroying 15,000 homes in its path. I found this one quite interesting because I've never heard of this one. 

Future arctic sea ice loss could dry out California

Arctic sea ice loss of the magnitude expected in the next few decades could impact California's rainfall and exacerbate future droughts, according to new research led by Lawrence Livermore National Laboratory (LLNL) scientists.

It's believed that with the decrease in sea ice will have a great impact on western part of the world. With less ice there will be less precipitation, which will lead to droughts and dry soil. The California region is already prone to wild fires and droughts and it's expected to get worse. As they project that the Arctic Sea Ice will be completely gone in the next decade or so. Leaving the West Coast dry with more severe drought and less precipitation.

Climate change: How do we know?

 Climate Change Evidence 

This article talks about the other various way we know that Climate Changes is certainly a fact. Other than the temperature is getting higher world wide or the more severe storms we have been having. It talks about the rise of acidity in the oceans due to the heightening amount of carbon dioxide in the water, which is bad for ocean life. I found interesting, also the lack in snow coverage during the winter. Satellites have shown that there is a decrease in snow coverage and it melts earlier than usual. It's interesting because I've noticed that we receive snow later than usual and it melts earlier also.

Severe weather warning for ice issued as UK reels from five-day freeze

The UK is facing another freezing night after a week that saw temperatures plummet lower than those in Moscow and Oslo.
Following a weekend gripped by the coldest temperatures of 2017, the freeze is expected to loosen its hold on Wednesday.
But a severe yellow weather warning will continue until 11am across most of England, Wales and Scotland, as remaining ice threatens treacherous conditions on roads and paths.
Many areas enjoyed a blanket of snow thick enough for sledging and snowmen.
Thousands of homes were also left without power. 
Disruptions also grounded flights and caused delays to and from airports including Birmingham, Manchester and Edinburgh. British Airways cancelled 170 flights on Sunday and more than 100 on Monday.

Meanwhile, rail disruptions caused travel chaos, with cancellations between Birmingham and Bristol after a landslide caused by the severe weather.

Snow in Hawaii?



Heavy snow is forecast to fall this week across the peaks of Mauna Kea and Mauna Loa on the Big Island thanks to a flow of deep moisture that's coming from the Intertropical Convergence Zone.  Winter storm watches have been posted there.
Snow on Hawaii's peaks is not uncommon in the colder months because they are nearly 14,000 feet high. Mauna Kea has a sub-Arctic climate, the weather service said.
“As long as we have deep enough clouds to support ice crystals, and when you have cold enough temperatures at the summit level, you can get snowfall,” said Matthew Foster, a meteorologist with the weather service in Honolulu.
A blizzard hit both mountains in late February. Mauna Loa and its sister peak of Mauna Kea are both volcanoes. Mauna Kea is the highest point in the state.

In fact, the coldest temperature ever recorded in Hawaii was 12 degrees on Mauna Kea on May 17, 1979, the weather service said.
While the summits receive snow, the rest of the Big Island and Maui are dealing with heavy rain and the potential for flash flooding over the next few days.

Severe Heatwave across Australia

 With the mercury set to soar above 30C across all capital cities, except Hobart, in the days ahead, Aussies are urged to stay out of the heat. Even Tasmania won’t be far off the 30C mark. Perth could get to 35C, Melbourne 36C and Adelaide a suffocatingly hot 38C.

Bureau of Meteorology meteorologist Ashleigh Langey said NSW would reach peak temperatures on Thursday, followed by a short cool change on Friday. 

“Over the next couple of days there will be a high pressure system influencing the state with pretty warm conditions. From Tuesday onwards it looks like we have got a low intensity heatwave developing, and by Thursday it will be a severe heatwave in parts of the state. There will be clear skies as well, which means things will heat up.”
Western Sydney will bear the brunt of the hot weather, climbing to 42C near Penrith and remaining in the mid to high 30s throughout the week.
“On Friday it will cool down to 27C because we have a southerly change moving through that will cool things down a bit,” she said.

Upsurge in Earthquakes Predicted for 2018







According to scientists from the University of Colorado, there is a strong link between the Earth's rotation and seismic activity. Several scientists have warned that there could be a significant upsurge in number of earthquakes worldwide next year. It disbelieved that the variations in speed of the Earth's rotation could cause severe seismic and unstableness, specifically in tropical areas that are heavily populated.

Although the rotations may be very small, it is argued that even that could be enough to create big amounts of underground energy to be impactful. Researchers were studying to find out what is the correlation between periods with high number of earthquakes and intense seismic activity, along with other factors that contribute as well. What they discovered was that when "Earth’s rotation decreased slightly it was followed by periods of increased numbers of intense earthquakes." Even the slightest rotation of the earth can be measured and expected to create some kind of impact in terms of earthquake, big or small. Two researchers that embarked on the study found that there is a common period of about 5 years where the Earth's rotation slowed a specific amount several times throughout the past century and a half. Thus, these periods resulting in a noteworthy increase in intense earthquakes. According to Roger Bilham, "This link is particularly important because Earth’s rotation began one of its periodic slowdowns more than four years ago." Suggesting that the Earth is giving us a 5 year heads up on earthquakes to occur in the future.
