Metal Wheels For Razors

Climate Change

On June 5, was held in Wellington, New Zealand, World Environment Day. The main theme of the event revolved around climate change and special attention has been devoted to the possibility that countries, industries and communities to change their behavior to achieve economies and lifestyles, low CO2 . In waiting to find trusted material with the news and the conclusions of the meeting, I would just say a few words on the effects of global climate change and global warming in Agron told us.

was born in 1995, the IPCC (International Panel on Climate Change) that, using the global meteorological network, estimated a temperature increase of between 1.4 and 5.8 ° C by 2100 with a one meter rise in sea level . Are the most pessimistic estimates of the Hadley Centre for climate research in Britain for the same period of time provides an increase in temperature from 7 to 10 ° C. If we assume an average of these forecasts for the next hundred years (to be very very loose) will encounter the following problems.

• The peripheral areas of polar glaciers will melt. The disintegration of permafrost in the north is already causing many problems in Canada and Alaska as the substrate, acquiring a slimy texture, is no longer capable of supporting infrastructure. While the South Pole is drastically reducing the number of some populations of animals.
• Alpine glaciers, which have remained stable from 1450 to 1850, will be reduced more than 40%.
• Coastal areas will be flooded. For concrete examples, with a 3 meter rise in sea, Manhattan would eventually flooded in many places, Wall Street and the World Trade Center. With a rise of 1 meter, 1 billion people face serious difficulties not only in terms of planning, but also because the virus local health, scattering at sea, they moved from one area of \u200b\u200bthe Earth. The issue of "environmental refugees" is already so worrisome that the High Commissioner for Refugees United Nations, created in 1950 to manage the exodus took place after World War II, declined any responsibility in this crisis. Currently, this problem affects about 25 million people around the world, but it could be of biblical proportions if the predictions of the IPCC, which are among the least pessimistic, prove to be accurate (according to the University of Oxford climate change will create approximately 150 million refugees by 2050).
• heat waves will increase. The summers are much warmer, but most occur sudden spikes in temperature that led to the death of the weakest and which involve an increase in the frequency and intensity of fires.
• The Mediterranean tend to become a subtropical extension of periods buckets and a thickening of the monsoon type rainfall that will become. These effects will be much stronger in areas with mountain ranges near the sea (Liguria, Apuan Alps, Sorrento, Calabria, etc.) and are an example of the floods in these areas: Genoa, Valle del Frigid-Serravezza, Sarno and so on.
• will change the salinity of the sea and with it the sea currents. This will lead to change the climate of Europe with a drop in temperatures and increased rainfall.
• subdesertiche In areas of Africa the rain will tend to become more uncertain. This situation will make the indigenous people unable to develop climate forecasts are essential to program storage systems.
• The production of some species of high interest in food will decrease. For example, it was learned that the fertility of rice, on which most power in Southeast Asia, a decrease of 10% increase of a degree above 30 ° C.
• plants and animals migrate. Two thirds of European butterflies live north of 50-300 km in a few decades ago.
• It transform ecosystems. Large semi-arid grassland in Arizona, Texas, Mexico, etc., with the increase in precipitation, can already see the emergence of shrubs.
• The boundaries of large parks will have to adapt to climate change to encompass ecosystems that have changed their boundaries.
• The colors of the landscape will vary. For example, the famous colors of the maples areas of southern Canada no longer found in that area they will be replaced by those of poplars will switch from red to orange to yellow.

I spoke estimates and for convenience I have used the future, but it is the wrong approach because mental problems caused by climate change are under way NOW and affect us. In witness whereof carry the words of the President of the Republic of Kiribati Anoto Tong: "It is becoming a problem, the simple survival. We continue to move towards the interior of the islands, as the sea continues to cover part of the beaches and coastline, but until we do that? [...] The countries that declined to sign the Kyoto Protocol must now take moral responsibility for what is happening. "
