Valuable lessons: Fair view about History of climate change.

The more you read the history, the more you will likely to know. Or even more, you could able to predict the future.

Categorically, If I’m writing, because I read substantially about the past.

To read any subject, you need to read about history on a particular subject. History teaches us a lot. Even more, I started watching History documentary too.

To me personally, when I started learning and delivering massive awareness about climate change, but I’m good and quite understood about what was happened regarding climate change over the last 5 years. Still I need to origin of climate that started deteriorating and I would like to some of the hard facts.

Here, I would like to submit the glimpse of data about History of climate change.

I should pin point the some of the historical moments and facts. An article from BBC news says, a brief history of climate change. In 1824 French physicist Joseph Fourier describes the Earth’s natural “greenhouse effect”. He writes: “The temperature [of the Earth] can be augmented by the interposition of the atmosphere, because heat in the state of light finds less resistance in penetrating the air, than in re-passing into the air when converted into non-luminous heat.”

And in 1896 – Swedish chemist Svante Arrhenius concludes that industrial-age coal burning will enhance the natural greenhouse effect. He suggests this might be beneficial for future generations. His conclusions on the likely size of the “man-made greenhouse” are in the same ballpark – a few degrees Celsius for a doubling of CO2 – as modern-day climate models.

In 1927 – Carbon emissions from fossil fuel burning and industry reach one billion tonnes per year.

In 1965- A US President’s Advisory Committee panel warns that the greenhouse effect is a matter of “real concern”.

In 1972 – First UN environment conference, in Stockholm. Climate change hardly registers on the agenda, which centres on issues such as chemical pollution, atomic bomb testing and whaling. The United Nations Environment Programme (Unep) is formed as a result.

In 1975 – US scientist Wallace Broecker puts the term “global warming” into the public domain in the title of a scientific paper.

In 1989 – Carbon emissions from fossil fuel burning and industry reach six billion tonnes per year.

In 1990 – IPCC produces First Assessment Report. It concludes that temperatures have risen by 0.3-0.6C over the last century, that humanity’s emissions are adding to the atmosphere’s natural complement of greenhouse gases, and that the addition would be expected to result in warming.

In 1992 – At the Earth Summit in Rio de Janeiro, governments agree the United Framework Convention on Climate Change. Its key objective is “stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system”. Developed countries agree to return their emissions to 1990 levels.

In 2006 – The Stern Review concludes that climate change could damage global GDP by up to 20% if left unchecked – but curbing it would cost about 1% of global GDP.

In 2006 – Carbon emissions from fossil fuel burning and industry reach eight billion tonnes per year.

In 2007 – The IPCC’s Fourth Assessment Report concludes it is more than 90% likely that humanity’s emissions of greenhouse gases are responsible for modern-day climate change.

In 2007 – The IPCC and former US vice-president Al Gore receive the Nobel Peace Prize “for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change”.

In 2011 – Data shows concentrations of greenhouse gases are rising faster than in previous years.

In 2013 – The first part of the IPCC’s fifth assessment report says scientists are 95% certain that humans are the “dominant cause” of global warming since the 1950s.

Additionally, there is an article from time magazine says, since roughly 1850, atmospheric CO2, the dominant greenhouse gas, has grown at an explosive rate, close to what mathematicians call “exponential.” Human population, GDP and fossil fuel emissions accelerated simultaneously in a similar manner.

Chart: John Brooke. Data: Population—Angus Maddison and U.N.; GDP—Angus Maddison and World Bank; Emissions—Tom Boden and Bob Andres, Carbon Dioxide Information Analysis Center at Oak Ridge National Laboratory, and Gregg Marland, Research Institute for Environment, Energy and Economics; Atmospheric CO2—NOAA.

Industrial emissions have driven atmospheric CO2 levels from about 280 to 410. Human populations are now surging toward eight billion. A doubling of CO2 from preindustrial levels, which is projected by 2075 — due to the combination of industrial emissions and huge volumes of ancient greenhouse gases rising from melting permafrost – will put the earth at CO2 levels not seen for 35 million years, the last time that Antarctica was ice-free. A quadrupling of CO2 would put us into the extreme hothouse conditions of the Jurassic era.

History says, By the 1930s, at least one scientist would start to claim that carbon emissions might already be having a warming effect. British engineer Guy Stewart Callendar noted that the United States and North Atlantic region had warmed significantly on the heels of the Industrial Revolution.

Callendar’s calculations suggested that a doubling of CO2 in Earth’s atmosphere could warm Earth by 2 degrees C (3.6 degrees F). He would continue to argue into the 1960s that a greenhouse-effect warming of the planet was underway.

While Callendar’s claims were largely met with skepticism, he managed to draw attention to the possibility of global warming. That attention played a part in garnering some of the first government-funded projects to more closely monitor climate and CO2 levels.

1988: Global Warming Gets Real

The early 1980s would mark a sharp increase in global temperatures. Many experts point to 1988 as a critical turning point when watershed events placed global warming in the spotlight.

The summer of 1988 was the hottest on record (although many since then have been hotter). 1988 also saw widespread drought and wildfires within the United States.

Scientists sounding the alarm about climate change began to see media and the public paying closer attention. NASA scientist James Hansen delivered testimony and presented models to congress in June of 1988, saying he was “99 percent sure” that global warming was upon us.

The UN Climate Action Summit reinforced d that “1.5℃ is the socially, economically, politically and scientifically safe limit to global warming by the end of this century,” and set a deadline for achieving net zero emissions to 2050.

This is fair view of history that I took some of the important key points. I sincerely encourage you all to visit further from these three sources. To me, it’s hard to choose the moments and facts. I hope you all will go further. If you have any suggestions, please comment below.


With respect.
