First signs of Climate Change appeared in the 1940s, study suggests

Study, conducted by United Kingdom climate scientists, shows that the first signs that global warming is happening could be observed in data collected back in the 1940s and 1960s.

The results of this study support the conclusions of the latest IPCC report (Chapter 10), where increasing global temperatures were linked to global warming.

That claim finds support in the YouTube video series, in which leading climate scientists, economists, energy experts, and other scholars discuss a host of topics ranging from the failures of alarmist climate science to the benefits of rising atmospheric Carbon dioxide concentration, the relation between science and religion, climate policy, and economic development for the poor.

An Australian research team has uncovered that climate change is not as recent of a global problem as previously thought. This meant smaller shifts in the temperature record due to global warming were more easily seen.

By examining average and extreme temperatures, researchers from the ARC Centre of Excellence for Climate System Science found that clear signs of global warming were visible in the tropics as early as the 1960s, but in parts of Australia, South East Asia and Africa it was visible as early as the 1940s.

According to scientific research, the tropics were the first regions to face the extreme temperature changes, mainly because they had a narrower range of temperatures. Their findings show that extreme rainfall events are soon to take place around the globe during the winter season in Russian Federation, Canada and Northern Europe. Always known as the most sensitive point to global warming, changes in climate temperature were recorded later in areas closer to the poles, but by 1980 to 2000, temperature records in most parts of the world were already showing the effects of global warming. The study was based on average temperature and extreme temperature readings. CPI’s 2011 report showed that, even within developing countries, only five per cent of climate finance went into adaptation, a crime that costs many lives every year in poor nations.

To determine when global warming started, the team analysed the change in average temperature.

The United States, particularly the eastern and central regions, were an exception to the global warming signal. “This is likely to bring pronounced precipitation events on top of the already existing trend towards increasingly wet winters in these regions”.
