According to scientists studying the ice cores, there is clear evidence of a rapid increase in temperature these past decades. ... BBC climate debate. Can be used to discuss climate change and earth movements (plate tectonics). The report, from the federal Climate Change Science Program, said trends seen over the last 50 years "cannot be explained by natural processes alone". Briefly explain the concept of continental drift. In recent years there have been signs of a seasonal shift - spring arrives earlier and winters tend to be less severe. This has created and will continue to create, a number of negative effects. The evidence for rapid climate change is compelling: Artic sea-ice is disappearing at a rate of 10% every decade. The use of tree rings, ice cores and glacial activity as evidence of climate change. When scientists take a core of ice it reveals the carbon dioxide and methane concentrations at the time the snow fell. Layers of accumulation and melting in the ice can reveal the temperature of each year for the past 400,000 years. Recent research has suggested that climate change may have been the killer blow that finished off our closest evolutionary cousins. The BBC quite rightly interviewed him on the BBC’s Radio 4 flagship program “Today”, a slot that literally millions tune into over breakfast or while commuting to catchup on the latest news. London Mayor Boris Johnson quashes the proposed rise in congestion charge for vehicles deemed high polluters. This will continue to create a number of negative and positive effects. Climate change Evidence has shown that Earth’s temperature is rising due to an increase in greenhouse gases. This has created and will continue to create, a … What is the evidence for climate change?

In 2007, the Intergovernmental Panel on Climate Change (IPCC) published its Fourth Assessment Report, which said changes to the climate were "very likely" the result of human activity. "Its survival has improved as winters have become warmer," he said. Without doubt, there are several phenomena happeningaround the world right now that serve as physical evidence of climate change.Needless to say, there is a lot of theory behind climate change, namely sophisticated climate models which describe 1. the greenhouse effect 2. the roles of various greenhouse gases (along with their GWP) 3. and climate feedbacksWithout further ado, here is a list of some of these changes that scien… A scientific report commissioned by the US government has concluded there is "clear evidence" of climate change caused by human activities. Climate change - Climate change - Evidence for climate change: All historical sciences share a problem: As they probe farther back in time, they become more reliant on fragmentary and indirect evidence. Evidence has shown that Earth’s temperature is rising due to an increase in greenhouse gases in the atmosphere. I've travelled all over the world for the BBC and seen evidence of environmental damage and climate change everywhere. It has a lot to do with predictability. I've travelled all over the world for the BBC and seen evidence of environmental damage and climate change everywhere. Dr Karell told BBC News that the brown owls, which used to form 30% of the tawny owl population in Finland, now make up 50%. Scientists believe there is a close link between the amount of these greenhouse gases in the atmosphere and global temperatures. "In other words, climate-driven selection has led to an evolutionary change in the population." It says the evidence is stronger now than when the Intergovernmental Panel on Climate Change carried out its last assessment in 2007. The US space agency's latest research into climate change has revealed a dramatic thinning of some ice regions in Antarctica.
