New evidence reveals global warming in the 1730s that wasnt man-madeAugust 4th, 2008 - 3:12 pm ICT by ANI
London, August 4 (ANI): New evidence uncovered by UKs Met Office has revealed that the world went through a period of global warming in the 1730s that could not have been man-made.
According to a report in The Sun, logs from the ships of Captain Cook and Lord Nelson, indicated that recent global warming is not so unusual after all.
The Met office scoured more than 6,000 Royal Navy logs dating from the 1600s.
Ships officers recorded air pressure, wind strength, air and sea temperatures and other weather conditions. From these records, scientists can build a detailed picture of past weather and climate, said Maritime historian Dr Sam Willis.
The findings are startling.
They show we went through a similar period of global warming in the 1730s that could not have been man-made.
Freak storms like the ones experienced recently also occurred in the 1680s and 1690s.
They were the coldest decades in what is known as the Little Ice Age so could not have been caused by global warming.
Cook mapped much of the Pacific before he was killed in Hawaii in a clash with the natives in 1779.
Nelson, who maintained his ships logs himself, covered the Arctic, West Indies, south east Asia and Mediterranean before his death at the Battle Of Trafalgar off the coast of Spain in 1805.
Other valuable records include those of the East India Company, which controlled much of the trade between Britain and Asia with its ships.
According to Geographer Dr Dennis Wheeler, of Sunderland University, British archives contain more than 100,000 Royal Navy logbooks from around 1670 to 1850 alone. They are a stunning resource.
Global warming is a reality, but our data show climate science is complex. It is wrong to take particular events and link them to carbon dioxide emissions. These records will give us a much clearer picture of what is really happening, he added. (ANI)
