Global Warming Hitting the Planet Worse than Expected

We’ve heard it all before. Global warming has been a huge issue since early 80’s, and since then it’s just getting worse and worse, more waste and carbon dioxide polluting our planet earth, and the rapid Increase in global population doesn’t help either, in fact, it’s the right opposite. Every new human being born on this planet contributes to the inevitable disaster that is about to come in the near future. But to give the way to something new and fresh, the old has to be destroyed. If you don’t like your old house, the best thing to do is to knock it down and build the new one from the scratch because sometimes it just doesn’t worth of try to fix it.

Also, there are hundreds of prophecies that kind of talk about this day which is is about to come, and put the thing in order by almost completely depopulating the planet. Some people are constantly giving the dates on which everything will happen, but I don’t think that anyone knows the exact date of apocalypse that is about to come. Everything has a lot to do with the Plane X, also called Nibiru, the 10th planet of our solar system which has different and unusual trajectory around the sun, and every couple of hundreds of years it passes closely around the planets and sun of our solar system, causing huge planetary changes, such as pole shift and deluge because of it’s 10x bigger size than planet earth and strong magnetic field. This all recorded in the history if we know where to look.

So, what is about to happen, happened already many times throughout our long 400 000 years history of humans and the global warming is just a small contributor to the inevitable event that is about to happen very soon. Let’s accept the rebirth of something new, fresh beginning.

Climate change projections have vastly underestimated the role that clouds play, meaning future warming could be far worse than is currently projected, according to new research.

Researchers said that a doubling of carbon dioxide in the Earth’s atmosphere compared with pre-industrial times could result in a global temperature increase of up to 5.3C – far warmer than the 4.6C older models predict.

The analysis of satellite data, led by Yale University, found that clouds have much more liquid in them, rather than ice, than has been assumed until now. Clouds with ice crystals reflect more solar light than those with liquid in them, stopping it reaching and heating the Earth’s surface.

The underestimation of the current level of liquid droplets in clouds means that models showing future warming are misguided, says the paper, published in Science. It also found that fewer clouds will change to a heat-reflecting state in the future – due to CO2 increases – than previously thought, meaning that warming estimates will have to be raised.

Such higher levels of warming would make it much more difficult for countries to keep the global temperature rise to below 2C, as they agreed to do at the landmark Paris climate summit last year, to avoid dangerous extreme weather and negative effects on food security. The world has already warmed by 1C since the advent of heavy industry, driven by CO2 concentrations soaring by more than 40%.

A lack of data and continuing uncertainty over the role of clouds is to blame for the confusion about warming estimates, said Ivy Tan, a graduate student at Yale who worked on the research with academics from Yale and the Lawrence Livermore National Laboratory.

“Models have been systematically underestimating the amount of liquid in clouds, meaning that we aren’t fully appreciating the feedback,” she said. “It could mean our higher limit of warming is now even higher, depending on the model, which means serious consequences for us in terms of climate change.

“This is one of the largest uncertainties left in climate change. We need to understand these feedbacks a lot better.”

Scientists Found the Most Distant Known Object in Our Solar System

There is so much new to be found in the undiscovered universe, and i am always glad to hear the new exciting news about the new planets within our solar system. So the new planet is further away than Pluto, on the outer side.


 

Astronomers using data from the Atacama Large Millimeter/submillimeter Array (ALMA) have found a distant object in the direction of Alpha Centauri. The object appears to be in the outer region of our solar system, and depending on its distance could be a hypothesized ”super-Earth.”

ALMA is capable of precise observations at short microwave wavelengths, typically emitted by cold gas and dust. But objects on the edge of our solar system also emit light in this range, and would be too cool and distant to be observed by infrared telescopes. In 2014, ALMA found a faint object in the direction of Alpha Centauri A & B. The object was again observed in May of this year, this time more clearly. Given that the object is within a few arcseconds of the Alpha Centauri system, it would seem reasonable to presume that it could be part of that system, possibly gravitationally bound as Alpha Centauri D. The Centauri system is about 4 light years away, and at that distance (given the object’s brightness at submillimeter wavelengths) it would have to be a red dwarf star. But such a star would also be clearly visible in the infrared, so if this object is Alpha Centauri D we should have seen it long ago.

Since it doesn’t seem to be part of the Alpha Centauri system, it must be closer and correspondingly smaller. With just two observations it isn’t possible to determine the object’s orbit, so we can only guess at its distance and size. One possibility (and the one I think most likely) is that it’s an extreme trans-Neptunian object about 100 astronomical units away from the Sun, which is further than Sedna at 86 AU. This would make it the most distant known object in the solar system, but likely smaller than Pluto.

Another possibility (which seems more likely to the object’s discoverers) is that it is about 300 AU away and about 1.5 times the size of Earth, making it the first “super-Earth” found in our solar system. Observations of trans-Neptunian objects have led to some speculation that one or two super-Earth’s could lurk in the outer solar system, so it’s not out of the question. There’s reason to be cautious of this idea, however, because of its location. Alpha Centauri is about 42 degrees away from the ecliptic. Most large solar system lay within a few degrees of the ecliptic, and even Sedna’s orbit is only inclined about 12 degrees from it. The chances of a super-Earth with such a highly inclined orbit seems very unlikely.

A third possibility is that the object is a cool brown dwarf about 20,000 AU away. Such an object should also be visible in the infrared, so there would still be the question as to why it wasn’t discovered by earlier infrared sky surveys. It’s proximity to Alpha Centauri would seem to make such an object easy to find.

The only way to know for sure is to gather more observations. Either by tracking its motion or by gathering observations at other wavelengths we can eventually get a handle on its size and distance. Whether dwarf planet, super-Earth or small star, it seems clear that something is lurking on the outer edge of our solar system.

How to Trick Your Brain to See Colors on Black and White Photo

This is absolutely amazing how we can trick our eye spectrum and brain, so we can see the things that are not there or we consider unreal. See this short 2 minutes video and try it yourself and let us know what you see.
