Global Warming report 2019

Main cause of Global Warming

First among them, there's no longer any question that rising temperatures and increasingly chaotic weather are the work of humanity. There's a 99.9999% chance that humans are the cause of global warming, a February study reported. That means we've reached the "gold standard" for certainty, a statistical measure typically used in particle physics.

The mechanism is well understood and has been for decades. Humans burn fossil fuels such as oil, coal and gas, which release carbon dioxide (CO2), methane and other gases into the Earth's atmosphere and oceans. CO2 is the greenhouse gas that's most responsible for warming.

Report past 5 year

The past five years have been the five warmest since record-keeping began in the late 1800s. The Earth has experienced 42 straight years (since 1977) with an above-average global temperature, according to the National Oceanic and Atmospheric Administration.

Based on five separate data sets that keep track of the Earth's climate, the global average temperature for the first 10 months of 2018 was about 1.8 degrees above what it was in the late 1800s.

That was when industry started to emit large amounts of greenhouse gases into the atmosphere.

Carbon dioxide up 46%

Increasing amounts of carbon dioxide and other gases being released into the atmosphere by industry, transportation and energy production from burning fossil fuels are enhancing what's known as the planet's natural greenhouse effect.

Carbon dioxide is the most prevalent among all greenhouse gases produced by human activities, attributed to the burning of fossil fuels.

The atmospheric carbon dioxide level for March was 411.97 parts per million and continue to rise.

It has now reached levels in the atmosphere not seen in 3 million years.

That's an increase of 46% from just before the Industrial Revolution in the 1800s, when CO2 levels were around 280 parts per million. Levels began to rise when humans began to burn large amounts of fossil fuels to run factories and heat homes, releasing CO2 and other greenhouse gasses into the atmosphere.

'The 42' Tallest building in India

The 42 The 42’ in Kolkata has now become India’s tallest building. After the construction of its 65th floor, 42 Chowringhee in Kolkata has become the country’s tallest building with a height of 268 meters. Dwarfing all the other major buildings around the city like Tata Centre and Everest House, this new wonder is redefining the skyline of Kolkata. The second tallest building in the city is at a whooping 167.8 meters and it’s named Urbana. Sadly, it falls just a 100 metes short to ‘The 42’. Owners of "The 42" The 42 project in Chowringhee, Kolkata is being built by a four-member consortium- Mani Group, Salarpuria Sattva, Alcove Realty and Diamond Group. Hafeez Contractor is working as a consultant on this project which is scheduled for delivery in December 2018.

"Types of Galaxies"

How many types of galaxies are there in the Universe? Edwin Hubble divided the galaxies into three basic groups: ellipticals, spirals, and irregulars. The ellipticals are smooth and round or elliptical, the spirals are flat with a spiral pattern in their disk, and the irregulars have stars and gas in random patches. Most galaxies are small and faint so only the luminous galaxies are seen at great distances. These spectacular galaxies tend to be either the elliptical or spiral type, so they are the ones often displayed in astronomy textbooks. Sprial Galaxy 15 percent of galaxies are spirals, flat galaxies with a central light concentration that show spiral arms in an outer disk. The central regions of spiral galaxies appear reddish and are composed of older Population II stars, such as those in the halo of the Milky Way Galaxy. Spiral galaxies range from intermediate to large galaxies, with masses in the range of 10 9 to 10 12 solar masses, diameters 6 kpc t...

सिंधु घाटी की सभ्यता: हड़प्पा सभ्यता

आज हम अपने भारत के इतिहास के बारे में पढ़ेंगे हड़प्पा सभ्यता जैसा कि आप सभी को पता है भारत की सबसे पुरानी सभ्यता सिंधु घाटी सभ्यता है जिसे हड़प्पा सभ्यता भी कहा जाता है इसका काल 2500 ईसा पूर्व से 1500 पूर्व है सिंधु घाटी सभ्यता का भारतीय इतिहास में एक विशिष्ट स्थान क्योंकि सभ्यता के आने से भारतीय इतिहास में मौर्य काल से पूर्व की विशिष्ट जानकारी प्राप्त होती है सिंधु घाटी सभ्यता विश्व की प्राचीनतम सभ्यता हूं जैसे मिश्र मेसोपोटामिया सुमेर एवं कीट के समान विकसित एवं प्राचीन थी यह ताम्र पाषाण संस्कृति भी है सर्वप्रथम 1921 में राय बहादुर दयाराम साहनी ने हड़प्पा नामक स्थान पर इस महत्वपूर्ण सभ्यता के अवशेषों का पता लगाया प्रारंभ में उत्खनन कार्य सिंधु नदी घाटी में ही किया गया तथा वही इस सभ्यता के अवशेष सर्वप्रथम प्राप्त हुए थे अतः इस सभ्यता को सिंधु घाटी सभ्यता कहा गया परंतु इस सभ्यता के अवशेष सिंधु नदी की घाटी से दूर गंगा यमुना के दोआब और नर्मदा ताप्ती के मुहाने तक प्राप्त हुए हैं अतः पुरातत्व वेदो ने पुरातत्व परंपरा के आधार पर इस सभ्यता का नाम उसके सर्वप्रथम ज्ञात स्थल के नाम प...

How to measure other "Galaxies or Planets" distance?

Several Techniques to Measure the Vast Distance Astronomers have developed several techniques to indirectly measure the vast distances between Earth and the stars and galaxies. In many cases, these methods are light year, parsec and astronomical unit. Astronomical Unit (A.U.) An astronomical unit (A.U.) is the average distance between the Earth and the Sun, which is about 93 million miles or 150 million kilometers. Astronomical units are usually used to measure distances within our solar system. For example, the planet Mercury is about 1/3 of an A.U. from the Sun, while the farthest planet, Pluto, is about 40 A.U. from the Sun (thats 40 times as far away from the Sun as the Earth is). 1 AU = 1.496 × 108 km = 93 million miles Light-Year (ly) Most objects in space are so far away, that using a relatively small unit of distance, such as an astronomical unit, is not practical. Instead, astronomers measure distances to objects which are outside our solar system in ...

Relation between "Time & Space"

What is space and time? In physics, spacetime is any mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams can be used to visualize relativistic effects such as why different observers perceive where and when events occur differently. Another corollary of special relativity is that, in effect, one person’s interval of space is another person’s interval of both time and space, and one person’s interval of time is also another person’s interval of both space and time. Thus, space and time are effectively interchangeable, and fundamentally the same thing (or at least two different sides of the same coin), an effect which becomes much more noticeable at relativistic speeds approaching the speed of light. Einstein’s former mathematics professor, Hermann Minkowski, was perhaps the first to note this effect (and perhaps...
