I pick the brains of Climate Central a lot in this blog and want to introduce a new tool they debuted yesterday! The Climate Shift Index (CSI, but not the TV show!) is designed to illustrate the influence of human-induced global warming in today’s real-time environment….the shift we’ve seen in temperatures. How much of these sweltering temperatures we’re experiencing right now can be directly contributed to our own global warming? You can see the graphic below illustrates the idea of today’s world versus what we’d have without the increased warming:
Here’s how it works and I’ll use yesterday’s high temperatures (Bush/IAH topped out at 98°–normal is 93°):
You can see across our part of Texas we were running in the 90-100° range. These numbers were 5-10° above normal (the temperature anomaly):
Climate Central uses their Climate Shift Index to categorize what role climate change plays in producing these above-normal temperatures and, on their CSI scale, we were a three:
Looking at the CSI chart below explains just what that three means:
Simply put, Climate Change made yesterday’s high temperature extremes three times more likely than had we NOT had so much climate change over the years. According to Climate Central the Climate Shift Index (CSI) levels indicate how much climate change has altered the frequency of daily temperatures at a particular location.
The scale works both ways in terms of climate change inducing higher temperatures and, in some cases, lower temperatures and you can go to the CSI page to choose whatever parameters you like — high or low temperatures and for what day. And this is in real time, so the beauty of it is that this isn’t a chart showing what changes have happened or might happen in the future, this index shows us daily what is happening to our planet.
