(Engsub+ vietsub) Climate change report highlight major impacts BBC news


Climate change is here now, says the UN report We can see it in fish migration patterns In melting Arctic sea ice In shrinking Himalayan glaciers like this one I visited last year We can see the damage to corals In short, the author says man-made climate change is a fact What report is saying is parts of climate change are reversible things have happened which won’t be able to turn turn a clock back But there is an awful lot of things that if we act now and reduce our carbon emissions we can prevent it getting worse we are more likely to get more severe floods in future as warmer air holds more moisture, the report says It urges politicians to cut emissions of CO2 to slow the warming But at the document launch in Japan the author says we must also adapt to the inevitable future changes to the climate it’s not that we are talking about identifying a particular thing that’s gonna happen in a particular place at a particular time It’s understanding how to be prepared in two critical ways One critical way is in decreasing the amount of climate change that occurs And the other is in finding way to cope as effectively as we can with the climate change that can’t be avoided It’s a small move towards adaptation to climate change What is more, they are building mini dams to block drainage channels dugged previously to improve farm productivity They are trying to catch water in a moss to prevent flooding This fragment moss stores 20 times its own weight in water And every drop of rain it’s caught up here doesn’t end up in a flood downstream We can improve farming, too Here in Cranfield University, they ‘ve created artificial mini fields and switch on the rain In the plot on the left the soil’s campacted by farm machines See how the water runs off compacted fields contribute to flooding I think we need to be smarter about how we manage our soil and manage our land I think certainly good soil management is the key to absorbing some of the rainfall events So to mitigate or reduce the impacts of some of the flooding that we’ve been having So there are things we can do but adapting to climate change does have its limits, the report says If we see a 4 degree C rise in temperature, we expect to see substantial extinctions widespread impacts on ecosystems large threats to agriculture and food security disruptions of water resources Extreme warming would also melt the Greenland ice caps Critics say today’s report is alarmist They say the climate simply won’t warm that much The UN panel says we have to make sure that it doesn’t
