How fast will the sea level rise? Much faster now.

Factors that accelerate polar and Greenland ice melt:

1. Arctic methane release, 50 Giga tons. The release has begun.

2. Fires. The 2018 wildfire season involves wildfires on multiple continents.

3. Energy related global greenhouse gas emissions rising. Even if they don't rise, they will still accumulate at over 35 gigatons per year from energy use alone.


4. Arctic amplification.

5. Accelerating melt of Antarctica since 1992 can take a nose dive.


6. Reduction of biomass carbon capture due to mass extinction.

7. Existing greenhouse gas concentrations will bring about global warming that will result in 10 meters to 20 meters of sea level rise. This is now certain. However, there are inflection points for ice melting, for instance temperature of 0 degrees Celsius must be reached for it to start to melt. A global inflection point may not have been reached yet as the Earth warms, thus when it is reached, ice could suddenly melt much faster. Present sea level rise is only 0.086 m, out of the certain 10 to 20 m.



8. Temperatures over 10 degrees Celsius can melt 10 cm of snow in 3 days. Arctic now exhibits 15 degree Celsius winter temperatures. Greenland glaciers will melt year round as temperatures rise, and they don't melt only on the surface, but underneath as well. They also calf and as pieces fall into the ocean these melt faster and immediately impact sea level rise. If they melt at a rate of 10 cm per day year round, it will take 55 years for all the ice to melt from that point alone... not accounting for the fact that ice melts from underneath or that it calfs. Antarctic is also getting warmer across the entire landmass and will reach a point of inflection. This means that Greenland melt alone with existing emissions in the atmosphere can result in 1.2 meter sea level rise per decade... not accounting for point 1 to 6 or the Antarctic melt.

"At the Insurance Council conference at Sky City, insurers were given updated - albeit draft - estimates that say $38 billion of New Zealand’s residential and commercial buildings may be at risk of flooding if sea levels rise one metre." - Eloise Gibson

"Bible’s Sodom and Gomorrah destroyed by 10 MEGATON asteroid explosion, archaeologists say"

https://www.express.co.uk/news/science/1048943/Sodom-and-Gomorrah-asteroid-impact-book-of-genesis-bible-archaeology

“The physical evidence from Tall el-Hammam and neighbouring sites exhibit signs of a highly destructive concussive and thermal event that one might expect from what is described in Genesis 19.

“The soil/ash samples gathered from Tall el-Hammam contain evidence of topsoil destruction and subsoil contamination with Dead Sea salts that would have prevented the cultivation of crops for many centuries following the event.”

Global warming climate change will require world wide mitigation of sea level rise. Coastal cities will get flooded and destroyed, unless protected by sea walls. People are losing their homes and businesses already. A global warming FUND for relocation of these people should be started. Instead of dealing with IDPs and climate refugees, nation states should create such funds and buy out threatened coastline properties making them into vacation rentals or otherwise re-purposing them, while resettling people preemptively, so no disturbance in the economy occurs as a result of their displacement, loss of livelihood and loss of employment... or worse: permanent disability and loss of life.

Radiative and indictive snow removal through sublimation or melting

I've brainstormed ideas on how to melt snow that piles up on roads instead of moving it, especially on city streets where too much of it has to be removed in dump trucks. Melting it with trucks that are powered by electricity, which cooks off the snow into vapor that flies off into the atmosphere, could be one way of doing it. Where the water can be poured out behind the truck, after the snow is melted and made into warm water inside it (nuclear fusion reactor on the truck would be good for this). The snow removal would thus use the hot water from the melted snow: 1. to rinse remaining snow and flow it off into the gutters, wells and off the road 2. heat the road somewhat so fresh snowfall would melt 3. the streets would be washed and cleaned with warm water First, I thought about an electric truck using radiative heating, then to heat the snow as the truck picks up off the ground while it moves. This would be a good solution to melt off the snow, however I ran into a problem

Trump's "Kill their families" vs. USA's WMD use, terrorism and war crimes

The sitting president of the United States demands that families of adversarial insurgencies be exterminated. He runs concentration camps for migrants where people are robbed, killed and raped . The US has used weapons of mass destruction, historically the country engaged in war crimes, terrorism , coups , torture and blackmail to gain geopolitical objectives. USA has committed about 10 genocides in pursuit of territorial acquisitions, political compliance , slave labor and resource grabs . How should the rest of the world view Trump's words when he says to " kill their families "? The United States as a belligerent , genocidal actor most of whose leaders are war criminals and refuse to recognize the International Criminal Court for fear of prosecution, but instead threaten the court judges with death and sanctions, has proven that it is its terrorist policy to commit genocide against adversarial nations as a means of subjugation. Rules of war, in case of

Hybrid Autonomous Mobile Drone Anti Tank Missile System

Image
Poland to win a defensive tank war against Russia... doesn't need tanks . What Poland needs is a new autonomous hybrid weapons system that combines self driving terrain vehicles with drones that can fly for several miles to engage armored units and fire one or two antitank missiles from low altitude. These weapon systems can sit in wait on the front lines and deny access to any incoming armored divisions very cheaply. They can be forward deployed and remotely controlled. Drones can be helicopter drones and thus VTOL, which means they can return to their ground vehicles where they are mounted and pick up additional missiles. Vehicles could field as many as 8 anti-tank missiles. What this means, is that this weapon system can engage tanks, mobile mortars, mobile artillery units and armored personel carriers from camouflaged locations by launching their drones, which subsequently can hit these armored units from beyond line of sight of the crew of the enemy ground vehicle it aims to n
