There was a lot of talk last week about the California drought, if climate change is causing it, how it is shaping it, so on and so forth. But now we have some actual numbers that can shed some light on the situation. It is fair to say that humans are costing California more water every year. Global warming, caused by people, is practically taking away the state’s water and moisture. And it’s going to get hotter.
The air around our planet is warming up, so the soil demands moisture. It has the same effect as a puddle: it’s hot outside so it evaporates quickly, but with earth it’s a lot more dangerous. The heat-up has been building up for years and it’s still building up. Once it completely “evaporates” we will have to wait almost the same amount of years to get all that moisture back. We might even have to wait more.
California doesn’t look like it’s going to get rid of the drought this week either, and a study conducted by a small group of scientists wanted to reveal exactly how much human-created climate change affects this drought. So here are the numbers: around 8 percent of the heat-up is caused by natural climate variables and another 27% can be blamed overall global warming.
Yes, global warming is more than three times higher than natural climate changes and this is bad for California. It is going to get hotter and hotter and its water resources are going to be put to the test, most likely until they completely drain out.
So what is going to happen exactly? The atmosphere is demanding moisture because of the rising levels of carbon dioxide, so California’s rising temperatures will increase dramatically. So scientists wanted to use a very interesting approach on how to measure these ever rising temperatures.
They considered California to be a total of 24,000 buckets, dispersed equally over seven square miles in area and they simulated the water changes that occurred every month in between 1901 and 2014. If it’s raining, the buckets fill themselves up and probably overflow too, while evaporation empties them.
This is how they discovered the amount of influence natural climate changes and global warming have on the hot state right now. And because of the variability of natural climate, drought conditions are expected to come back over and over again. If this is the future of California, something needs to be done fast, otherwise the state will literally burn until there will be no more water left.
