A hundred years from now, catastrophic climate change may have completely changed the way our children and grandchildren live, work and farm. Possible doomsday scenarios include a shutdown of the Gulf Stream, which Ireland depends on for its relatively mild weather, leading to another ice age.
The science is incontrovertible. Global warming is man-made, and emissions of carbon and other gases are the main culprit. Sure, Ireland makes up only a small amount of total emissions. Because of its size, China alone accounts for more than a quarter of all emissions annually. The US, another 15%. But, we rank highly in emissions per person, and total emissions are going in the wrong direction, up 3.5% in 2016 when the government is targeting a 5% reduction.
While the worst environmental impacts of climate change might still be some way off, we could be facing a bill of nearly half a billion euro every year from 2020 onwards unless we get our house in order. As part of European and global efforts to reduce emissions, we have committed to a reduction of 20% (from 1990 levels) by 2020. Ireland is one of the few EU countries on course to miss its target, leaving itself open to annual fines equivalent to widening the standard income tax band by €2,500 or building 2,500 social houses.
