This article discusses the overwhelming evidence on global warming which should be our cue to take action now.
Over 90 per cent of the heat trapped in the climate system by increasing greenhouse gas concentrations from our burning of fossil fuels is stored in the oceans. With much less variability than surface temperatures, ocean warming is one of the most important indicators of the ongoing pace of climate change.
Two new studies published last week confirm the world’s oceans are warming. The first, published in the Proceedings of the National Academy of Science, shows that ocean warming has accelerated since 1870. The second, a perspective published in the prestigious Journal Science, reports studies that indicate the rate of ocean warming over recent decades is 10 per cent or more greater than the studies considered in the last Intergovernmental Panel on Climate Change Assessment published in 2013, and that the rate has increased since 1991.
