Introduction

Before the 1880s, manufacturers made newspapers from cotton and linen rags boiled to a pulp, spread into a mold and dried between pieces of felt. These newspapers have a slightly thick texture and may feel rough to the touch. Due to the molding process, the edges of the paper are sometimes imperfect.

Depending on the purity of the rags, old newsprint usually appears white, cream or gray in color. There were times when cotton or linen materials were in short supply, and manufacturers printed on "necessity" paper such as wallpaper, cornhusks, lined notepaper or other suitable material.

Around 1880, manufacturers used cheaper wood pulp to produce newspapers. This more modern newsprint has a thinner and smoother texture, compared to the higher-quality cotton and linen rag paper. If your newspaper is dated prior to 1880 but does not have the look and texture of cotton rag paper, it might be a reproduction.

Newspapers published after 1880 frequently appear brown or yellowish in color, because the harmful acids in the wood pulp paper have resulted in deterioration. This color may apply to the entire newspaper or just around the edges. These acidic newspapers are commonly brittle and fragile, with edges that easily chip. Be wary of items dated prior to 1880 that exhibit these characteristics.

The most obvious clue that a newspaper is a reproduction are the words "reprint" or "facsimile" in small type somewhere on the paper. A reproduction may also contain printing errors, advertisements or illustrations that do not exist in the original.

Being late for awareness

The consequences of global warming that we now know it is likely to increase and extend may be heavy for humanity. Scientists, politicians and citizens are generally aware of the need to take measures to limit global warming, but often individually reluctant to put their ideas into practice. 

Since the Rio Summit in 1992, which called for the international responsibility to save the planet, awareness of climate change took place, and strategies have been proposed to limit the emission of greenhouse gas emissions. The Kyoto Protocol, which deals with this aspect is still at an impasse because of the refusal to sign from countries whose industrial activities are highly generating greenhouse gas emissions. 

The Story of a fraud, or Global Warming 

This was a controversial documentary, which suggests that the formation of scientific consensus on global climate change was influenced by funding and political factors. The program was officially criticized by the British Office of Communication, which upheld the complaint on the distortion of the views of David King. The film, created by the British television director-producer Martin Durkin ( Engl. Martin Durkin), represents the opinion of scientists, economists, politicians, writers and others who challenge the scientific consensus on man-made causes of climate change. 

According to Hamish Mikura, head of documentaries, the purpose of the film - "represent the point of view of a small minority of scientists who do not believe that global climate change caused by anthropogenic emissions of carbon dioxide". 

Although the documentary was viewed positively by scientists skeptical of the idea of global warming, it has been criticized by ...
