climate change

in the near future  climate change is to become the most a common treat to hall world . its happening now , not just start to happen from days or month , climate change begin to start before the 1800 es . in 1712 British   ironmonger tomas new comen invents the first widely used steam engine , making the way to industrial revolution . and 1800 earth population  reached one million .

                                   in 1927 carbon emission from fossils fuel burning  and industry reach one billion tonnes per year, so this change of climate not just a simple thing , it has a long history ,now almost too much damage has done, antarctic ice glaziers almost stating to melting and its happening so fast , when ice melting to the sea then sea level goes high ,its cosign lots of trouble to country's , specially sea level country's  

u can see how dangers this thing , if we let it happen this is what we can see near future , from the climate change glaziers melting is not  only one thing effect to our system , its  changing our raining system , and wind  winter summer all this systems getting jam from this climate changing , 

                                                                      carbon emissions present age going high , because of we using coal plants for our energy system , its very bad for over environment , from vehicles , factory's, and other industry's , carbon emission getting high in our environment . good thing is lots of country's now scatting  down there coal plants , its good thing but damage is done so far now . 

Australia records warmest autumn ever                                   

 the mean temperature between march and may was 23.86c in aus  

climate change is an environment issue

changing the climate effect our environment and living system its effect our food production , water , good air , temperature going high , floods, forests getting burning   , and lots more harms , global warming and climate changing not just a two things ,its same thing .climate changing happens because of global warming . this climate changes more effect tomorrow other than today .

 

                        

 

the earth climate has changed throughout history . just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7000 years ago marking the beginning of the modern climate era- and of human civilization. most of these climate changes are attributed to very small variations in earths orbit that change the amount of  solar energy our planet receives 



the evidence for rapid climate change 

sea level rise - global sea level rose about 17 timeters(6.7inch)in the last century. 

global temperature rise - all three global surface temperature reconstructions show that earth has warmed since 1880 most of this warming has occurred since the 1970s with the 20 warmest years having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years .

warming oceans - the oceans have absorbed much of this increased heat with the top 700 meters(about 2,300 feet) of ocean showing warming of 0.302 degrees Fahrenheit since 1969

shrinking ice sheets - the Greenland and antarctic ice sheets have decreased in mass data from NASA gravity recovery and climate experiments show Greenland lost 150 to 250 cubic kilometers of ice per year between 2002 and 2006 ,  

declining arctic sea ice - both the extent and thickness of arctic sea ice has declined rapidly over the last several decades
