While the sinking of the Titanic in April 1912 is usually blamed on construction flaws or human error by the captain and crew, a newly published study in the scientific journal Significance points to other factors.
Specifically,there were a greater number of icebergs than normal that year, and weather conditions had driven them further south, and earlier in the year, than was usual.

That's particularly significant, because those conditions are happening again now, thanks to climate change. As the article's authors point out, iceberg discharge from glaciers is increasing, with more heavy iceberg years since the 1980s than before, and increasing global warming will likely cause this trend to continue.
One of the co-authors, University of Sheffield geographer Grant Bigg, says: "As use of the Arctic increases in the future with declining sea-ice, and as polar ice sheets are increasingly losing mass as well, the iceberg risk is likely to increase in the future, rather than decline."
