The 50th of Earth Day, an international event, fell on 22 April this year and was marked by President Biden’s Leaders’ Summit on Climate. It is encouraging that he is determined to forge ahead with reducing carbon emissions in the US and to reverse the damage done by his forebear. Worryingly however, China continues to build new coal fired power plants and is the world’s top emitter of carbon, whilst conversely being a top producer of alternative energy or the means to generate it (solar panels etc.). Whilst emissions fell worldwide during the pandemic in the first half of 2020, they have risen in 2021. Ireland has introduced its Climate Action Bill and aims to reach carbon neutrality by 2050. Some people are unhappy with some of the actions that must be taken, but they are essential if the world’s temperature rise is to be kept below 1.5⁰C. The more countries that become carbon neutral, the more possible it will be for other countries to follow suit. Reducing (and ultimately eliminating) our reliance on fossil fuels whilst converting to the use of green technology will be critical to our change to carbon neutrality.
