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.

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...

Galaxies in the Universe...

How do we know there are Billions of Galaxies? Our universe contains at least two trillion galaxies – 10 times more than we thought. Astronomers led by Christopher Conselice at the University of Nottingham in the UK converted “pencil beam” images of deep space stretching some 13 billion light-years into 3-D maps, allowing them to calculate the density of galaxies in that volume. This latest analysis uses mathematical models to estimate the number of both visible and hidden galaxies in snapshots like Hubble's famous Deep Field image. Using this method, Christopher Conselice, who studies galaxy formation at the University of Nottingham, and his team came up with a surprising conclusion: The models suggest that only about ten percent of galaxies in the universe are observable from Earth. That means our current technology misses about 90 percent of what’s out there, including trillions of galaxies, each with tens or hundreds of b...

Dwarf: Definition & Type

Type of Dwarf A star is a giant ball of extremely hot gas (plasma), sustained by nuclear fusion which turns hydrogen into helium. All this energy produces heat, light and bigger chemical elements. A star emits electromagnetic radiation that moves away from the star as light. The large mass of a star holds it together. Old stars change helium into other elements like carbon and oxygen. Yellow dwarfs - main-sequence stars like our own Sun, Alpha Centauri A, Tau Ceti, etc, typically about 80 - 100% of the size of the Sun, and actually more white than yellow. They are also known as G V stars for their spectral type G and luminosity class V. White stars - bright, main-sequence stars with masses from 1.4 to 2.1 times the mass of the Sun and surface temperatures between 7,600°C and 10,000°C, such as Sirius A and Vega. Red giants - luminous giant stars of low or intermediate mass (usually between 0.5 and 10 solar mas...
