The frequency of episodes of extreme heat and rainy events worldwide has increased and the pattern is expected to continue.
Extreme weather events that occur in summer, such as heatwaves, droughts or rainy periods, could increase their duration if global temperatures rise 2 degrees compared to pre-industrial levels, according to a study released on Monday, August 19.
Peter Pfleiderer of the Climate Analytics Center in Berlin and a group of colleagues presented in the latest issue of the journal Nature an analysis of the persistence of weather conditions in the latitudes of the Northern Hemisphere.
With global warming, the frequency of episodes of extreme heat and rainy events worldwide has increased and this pattern is expected to continue.
Experts have warned, as the scientific journal recalls, that the rise in extreme temperatures and rainfall can have an impact on people's health, agriculture and the environment.
The study indicates that extreme meteorological phenomena are usually measured by their intensity or frequency, but it is generally the duration or persistence of these events that generate the most serious effects.
Pfleiderer and his research team warned that if temperatures rose 2 degrees Celsius - relative to preindustrial levels - periods of heat lasting more than two weeks could increase by about 4%.
Accordingly, an increase of up to 20% in periods of persistent heat and drought could occur in the northeastern United States.
The authors of the research also stated that episodes of heavy rains that last more than a week and that can lead to flooding could increase by 26%, if temperatures rise 2 degrees.
== never ever was a warming period a problem for humans.== Since homo sapiens came into existence 200,000 years ago, the earth has never been as warm as it is today. So history does not reveal whether human beings can cope successfully with much higher ocean levels and more extreme weather.
I am a German and i know Mr. Pfleiderer from the University. These climate guys gets lots of money for their nonsense. The world climate always has changed never ever was a warming period a problem for humans. These hoax guys know this exactly and Germany is the biggest producer of this hoax. They will have more Russian problems in this overtaxed and freedomless country than warm weather ( by the way that would be for good. German weather is worst.) I live in Florida directly at the coast. Show me the sera level rising and in Germany show me the heat waves ???!!!! Nothing is happen except that the climate is constantly changing and will do so in the future.
Panama | How to Reverse Climate Change...Immediately! CO2 Facts! Carbon Dioxide is often said to contribute significantly to adverse weather effects. Carbon Dioxide is said to absorb the sun rays and trap the heat. Heat is absorbed by the oceans and the heat molecules of gas cause the turbulence. Turbulence like boiling water at atmosphere temperatures above 90 to 100 degrees Fahrenheit. ----[Immediate Hot Water Solution]--- The Global Manufacturing Process...generates...[>HEAT<].... [>HEAT<]: is derived by process of fire melting metals...iron, steel and aluminum. Boiling spaghetti...hot dogs...ramen soup...etc. Taking a hot bath and flushing it into the oceans. The oceans absorbs the global hot waters and manufacturers from 6 - 7 billion peoples. Chemicals in the oceans may contribute to the release of energy in the form of heat. Chemicals such as acids and neutralizers. Water treatment plants may not neutralize the water heat temperatures only pollutants. Dirty water technically clean can absorb extraordinary amounts of solar energy. Solve human water boiling disposals into oceans should provide immediate weather effects relief.
It is called “weather”. It changes just like it always has. People are so gullible and superstitious. “We must sacrifice to appease the enviro-gods.”, they scream. Grow up. It is just freakin weather.
