5 things our kids will not know about Earth High temperatures this summer, which led to drought and fires reminded the public discussion about global warming and, in  particular, about the irreversible changes that will occur. Many of these changes occur so fast that the next generation will not know what a reindeer is a ski track or what they taste strawberries.  The latest warning they gave NASA scientists who observed 97% melting of the ice sheet in Greenland in just four days. Satellite image was shocking, considering that in the last 30 years the ice has thinned by only 55%. While four days ago, Greenland was covered in 40% ice, thick ice today continent is only in certain parts.  Although difficult to do, weather predictions announces that the coming years will be marked by heat waves, droughts, floods and viole nt storms. All this will lead to irreve rsible change s in Eart h's geography , with irrevers ible conseque nces. Experts warn that some species of animals and plants will be our children's generation unknown  I have put together a selection of the most important changes, grouped into five categories, with one page for: disappearance of species, changing Earth's geography, disappearance of species of plants, telecommunications and restrictions affecting the risk of allergies and pandemics. 1. Extinction of species The first consequence of the ice sheet thinning and disappearance of the Arctic and sub-Arctic areas will be the disappearance of  polar bears, penguins and other animals whose habitat is affected. Not only that they will not be able t o live on land and have cubs,  but can not find the food they need. Because winter shorter entries 40-73% of female polar bear does not carry to term and food scarcity leads to a strange phenomenon: cannibalism among bears.  Second, warming temperatures in northern regions of the planet will affect other animals, such as reindeer and elk. U.S. News & World report shows that increasi ngly more reindeer die of food scarc ity or lack of them now, either because of low resistance to diseases caused by poor diet during the period of growth.  A third consequence is the disappearance of trout and salmon fish are used to living in cold waters. Biologists expected that these species will disappear at a rate of 18-38% of normal habitat by the year 2090. 2. Changing the geography of the Earth With heavy cutting of trees, Amazon also face dangers that put climate change. A study conducted in 2009 by U.K. Met Office revealed that a global temperature rise of 4 degrees can lead to the destruction of rain forest at a rate of 85% in the next century. An increase of just 2 degrees Celsius, can destroy 20-40% of existing species of plants and animals.  All because of climate change, our children will not know what a beach or ski slope. A second consequence of increasing global temperature and thus melting glaciers and rising sea levels and ocean beaches will be erosion and disappearance. A report issued in June by the Natural Resources Defense Council found that the Pacific Ocean will increase by a few inches in the coming decades and becomes 1 meter higher by the end of this century.  All high temperatures are to blame for the disappearance of ski slopes, which now increasingly fewer days with snow every year. 3. Reduce the production of peanuts, honey and cocoa According to the USDA (U.S. Department of Agriculture) bee population has declined globally due to wet winters and rainy summers. Due to weather conditions, bees starve or are malnourished and dying of disease. However, a smaller number of bees and  pollination affects plant species , which will soon disappear.  Secondly, sugar cane production fell by 30% due to climate change occurred from 2009 to present. The same goes for the  production of cocoa and strawberry peanut, lower production due to very high temperatures. Currently, Bill and Melinda Gates Foundation seeks solutions for shifting cultivation of cocoa beans in other areas. 4. WiFi communication impairment A 2011 report of the British Department for Environment, Food and Business Rurare found that climate change may affect infrastructure and wireless communication. Thus, high temperatures and storms affect signal strength, while wetter winters and drier summers may affect wiring and connections between them. 5. Multiply allergies and the risk of pandemic Global warming is bad news for those with allergies. High temperatures and winds of summer pollen dispersal multiply, according to a 2011 study conducted by Mount Sinai School of Medicine in New York.  Along with allergies, climate change may be related to other infectious diseases. According to a study climate affect bird migration, increasing the risk of pandemic influenza.

5 things our kids will not know about EarthHigh temperatures this summer, which led to drought and fires reminded the public discussion about global warming and, in particular, about the irreversible changes that will occur. Many of these changes occur so fast that the next generation will not knowwhat a reindeer is a ski track or what they taste strawberries. The latest warning they gave NASA scientists who observed 97% melting of the ice sheet in Greenland in just four days.

While four days ago, Greenland wascovered in 40% ice, thick ice today continent is only in certain parts. Although difficult to do, weather predictions announces that the coming years will be marked by heat waves, droughts, floods and

violent storms. All this will lead to irreversible changes in Earth's geography, with irreversible consequences. Experts warn thatsome species of animals and plants will be our children's generation unknown I have put together a selection of the most important changes, grouped into five categories, with one page for: disappearance of species, changing Earth's geography, disappearance of species of plants, telecommunications and restrictions affecting the risk of allergies and pandemics.

5 lucruri pe care copiii noştri nu le vor şti despre Pământ

Temperaturile foarte ridicate din această vară, care au dus la secetă şi incendii au readus în atenţia publică discuţia despre încălzireaglobală şi, în mod special, despre schimbările ireversibile ce vor avea loc. Multe dintre aceste schimbări vor avea loc aşa de repedeîncât generaţia următoare nu va mai ştii cum arată un ren, ce este o pârtie de ski sau ce gust au căpşunile. Cel mai recent semnal de alarmă l-au dat cercetătorii de la NASA care au observat topirea în proporţie de 97% a stratului de gheaţădin Groenlanda în doar patru zile. Imaginea din satelit a fost şocantă, în condiţiile în care în ultimii 30 de ani stratul de gheaţă s-asubţiat cu doar 55%. În timp ce acum patru zile, Groenlanda era acoperită în proporţie de 40% cu gheaţă, astăzi continentul aregheaţă groasă numai în anumite porţiuni. Deşi dificil de făcut, predicţiile meteorologice anunţă că următorii ani vor fi marcaţi de valuri de căldură, secete, inundaţii şi furtuniviolente. Toate acestea vor conduce la schimbări ireversibile în geografia Pământului, cu consecinţe ireversibile. Specialiştiiavertizează că anumite specii de animale şi de plante vor fi necunoscute generaţiei copiilor noştriAm alcătuit o selecţie a celor mai importante schimbări, grupate în cinci categorii, cu câte o categorie dedicată: Dispariţia unor specii de animale, modificarea geografiei Pământului, dispariţia unor specii de plante, afectarea telecomunicaţiilor şi reştrea risculuide alergii şi pandemii.

1. Dispariţia unor specii de animale

Prima consecinţă a subţierii şi dispariţiei stratului de gheaţă din zonele arctice şi sub-arctice va fi dispariţia urşilor polari, a pinguinilor şi a celorlalte animale al căror habitat este afectat. Nu doar că aceştia nu vor putea să locuiască pe uscat şi să aibă pui,

dar nici nu vor putea găsi hrana de care au nevoie. Din cauza iernii mai scurte, întrr 40-73% dintre femelele de urs polar nu ducsarcinile la termen, iar împuţinarea hranei duce la apariţia unui fenomen ciudat: canibalismul între urşi. În al doilea rând, încălzirea temperaturilor în zonele nordice ale planetei va afecta şi alte animale, precum renii şi elanii. Un raportamerican News & World arată că din ce în ce mai mulţi reni mor ca urmare a împuţinării hranei, fie din cauza lipsei ei în prezent, fiedin cauza rezistenţei scăzute la boli, determinată de o alimentaţie necorespunzătoare încă din perioada de creştere. O a treia consecinţă este dispariţia păstrăvului şi a somonului, peşti care sunt obişnuiţi să trăiască în ape reci. Biologii preconizeazăcă aceste specii vor dispărea în proporţie de 18-38% din habitatul normal până în anul 2090.

2. Modificarea geografiei Pământului

Împreună cu tăierea abundentă a copacilor, pădurea amazoniană se confruntă şi cu pericolele pe care le pun schimbările climatice.

Un studiu realizat în 2009 de U.K. Met Office a relevat că o creştere a temperaturii globului de 4 grade poate duce la distrugerea pădurii amazoniene în proporţie de 85% în următorul secol. O creştere de doar 2 grade Celsius, poate distruge între 20-40% dintrespeciile de plante şi animale existente. Tot din cauza schimbărilor climatice, copiii noştri nu vor şti cum arată o plajă sau o pârtie de ski. O a doua consecinţă a creşteriitemperaturii globale şi, implicit, a topirii gheţarilor şi creşterii nivelului mărilor şi oceanelor, va fi eroziunea plajelor şi dispariţia lor.Un raport emis în iunie de Natural Resources Defense Council a relevat că nivelul oceanului Pacific va creşte cu câţiva centimentriîn următoarele decenii şi va ajunge să fie cu 1 metru mai ridicat până la sfârşitul secolului acesta.Tot temperaturile ridicate sunt de vină şi pentru dispariţia pârtiilor de ski, care au în prezent din ce în ce mai puţine zile cu zăpadăîn fiecare an.

3. Micşorarea producţiei de arahide, miere şi cacao

Potrivit USDA (Departamentul American de Agricultură) populaţia de albine a scăzut la nivel global din cauza iernilor umede şi

verilor ploioase. Din cauza condiţiilor meteo, albinele mor de foame sau sunt subnutrite şi mor din cauza bolilor. Totodată, unnumăr mai mic de albine afectează şi polenizarea unor specii de plante, care astfel vor dispărea.În al doilea rând, producţia de trestie de zahăr a scăzut cu 30% din cauza schimbărilor climatice petrecute din 2009 până în prezent.La fel se întâmplă şi cu producţia de cacao de arahide şi de căpşuni, producţii mai mici din cauza temperaturilor foarte ridicate.Momentan, Fundaţia lui Bill şi Melinda Gates caută soluţii pentru mutarea culturilor de boabe de cacao în alte zone.

4. Afectarea comunicaţiilor wifi

Un raport din 2011 al Departamentului Britanic de Mediu, Alimentaţie şi Afaceri Rurare a descoperit că schimbările climatice potafecta infrastructura şi comunicaţia wireless. Astfel, temperaturile ridicate şi furtunile afectează puterea semnalului, în timp ceiernile mai umede şi verile mai secetoase pot afecta cablurile şi legăturile dintre acestea.

5. Înmulţirea alergiilor şi riscul de pandemie

Încălzirea globală este o veste proastă şi pentru cei alergici. Temperaturile ridicate şi vântul din sezonul cald pot înmulţi răspândirea polenului, potrivit unui studiu din 2011 realizat de Mount Sinai School of Medicine din New York. Împreună cu alergiile,schimbările climatice pot fi legate de alte afecţiuni infecţioase. Potrivit unui studiu, clima afectează migraţia păsărilor, crescândriscul de pandemii de gripă.
