The world’s top climate scientists warn that humanity’s influence on the climate is unequivocal, with wide-ranging impacts across the planet, from rising seas to melting ice.
The UN’s climate science panel, the Intergovernmental Panel on Climate Change (IPCC), is currently working in Copenhagen to undertake the final wording of its report that will represent the most comprehensive account of the state on climate science in seven years.
This work will be a summary of three major reports that have already been published over the course of the last 13 months: one on the physical science of climate change, one on its impacts on ecosystems, our food supply and how we adapt, and one on the solutions, as the reduction of emissions from power plants, factories, cars and farms.
The report will highlight the importance to take into account the human role in global warming. According to experts, human influence on the climate system is evident: recent anthropogenic emissions of greenhouse gases are the highest in history as data show.
In relation to that, the atmosphere and ocean have warmed, the amounts of snow and ice have diminished, and sea level has risen, experts say.
Studies reveal that over the past decade, emissions grew at twice the rate of the previous 30 years.
In this context, governments must take action undertaking concrete measures to achieve the substantial emissions reductions necessary to tackle climate change related issues. Moreover, governments need to take into account projects on the long term, in order to meet the targets.
Data indicate that the warming isn’t evenly spread: the tropics and higher latitudes have got hotter faster than other regions.
In addition to that, the draft report has outlined the urgency of the current situation saying that since the mid-19th century, the rate of sea level rise has been larger than the rate during the previous two millennia.
