The United Nations has warned a prompt change to wind and solar power is required if the world is to steer clear of catastrophic global warming.
Releases of greenhouse gases need to be slashed by up to 70% before 2050 to manage climate change, the Intergovernmental Panel on Climate Change (IPCC) has said. ‘Large-scale changes in energy systems’ are needed, along with coal power stations to be turned off and wind and solar to be put in its place.
This alteration needs to be carried out within the next 15 years or controlling climate change will eventually become progressively harder and more costly.
The report was published in Berlin, written by 235 international scientists and economists, they stated that efforts so far have failed to stop spiralling emissions of greenhouse gases – which have risen to ‘unprecedented levels’ in the past decade. Ottmar Edenhofer, co-chair of the authors said: “There is a clear message from science: to avoid dangerous interference with the climate system, we need to move away from business as usual.”
The IPCC report is the first extensive evaluation in 7 years of the options for dealing with climate change. It is the last part in a trilogy of IPCC reports on the causes, impacts and solutions to climate change.
The first section, issued last September, discovered that scientists are 95% positive that human beings are the ‘dominant cause’ of global warming.
The second part, published three weeks ago, suggested that the harsh effects of climate change are ‘already occurring on all continents and across the oceans’.
The final part, published just over a week ago on the options for diminishing global warming, warns that we have got to immensely minimize our use of fossil fuels.
“Without additional efforts to reduce greenhouse gas emissions beyond those in place today, emissions growth is expected to persist driven by growth in global population and economic activities,” the report threatens.
If no effort is taken, global temperatures will increase by up to 4.7C by the end of the century, which scientists are convinced it will create unrepairable and substantial damage to the planet.
The scientists are confident that if renewable energy is swiftly carried out, homes are built in a more viable and energy efficient way, and human utilization and wastefulness is changed, climate change can be controlled!
