Whilst the negative effects of climate change can be catastrophic, not everything is doom and gloom !
Migration of fish species will mean fishermen in some areas will have more to catch . For example, sea bass, red mullet and squid are expected to migrate into UK waters . But many fish will suffer from climate change .
Global warming can benefit crops – warmer temperatures and more carbon dioxide make some plants grow faster . However, in most areas, the problems for agriculture caused by climate change will be worse, such as long droughts, and flooding by seawater [12,13]. Responses differ between crops: sugarcane will benefit from higher temperatures, but many other crops will suffer, including wheat, rice, and oil seeds .
In the winter of 2017-18 about 50 thousand people died due to cold weather in England and Wales . Warmer winters will mean fewer people die from cold in the winter . But deaths from summer heat will likely increase, offsetting the winter benefit .
As summer temperatures increase, some places will become more popular tourist destinations . Whilst this may benefit the economy, it could damage wildlife as tourist resorts are built . In other areas, tourism will suffer due to high temperatures, rising sea levels flooding coasts, and death of coral reefs [7,10].
As ice melts, new shipping routes will open up . For example, the Northwest Passage through the north of Canada will become ice free for more of the year, making trade by ship transport faster and cheaper [3,11].
Unfortunately, the cons of climate change vastly outweigh the pros . Relatively small short-term benefits will be dwarfed by much more serious negatives if temperatures continue to increase . But alongside working to limit climate change, we should adapt how we live, farm, build etc. to make the most of the benefits climate change brings .
