Human-induced climate change reversed 6,500-year global cooling trend

What would Earth’s climate naturally be doing if it weren’t for human intervention? Researchers at Northern Arizona University have now analyzed over 12,000 years of climate data, and found that human-induced warming interrupted and reversed a long-term natural global cooling period.

It’s no secret that the Earth is heating up at an incredible speed, with recent months, years and decades all breaking temperature records. But this data only goes back to the 1880s, when observations began being routinely recorded. So how does the current trend compare in the longer term?

To find out, researchers have been compiling data from various sources that stretch back many millennia. A few months ago, a team of 93 scientists published a particularly comprehensive record of paleoclimate data, spanning the past 12,000 years. It includes 1,319 data records from samples like lake deposits, marine sediments, peat, cave deposits, coral, and glacier ice cores, collected from 679 sites around the world.

From that, the researchers were able to chart changes in the surface air temperature over the last 12,000 years – a time when the world was coming out of the last Ice Age. This was then compared to the average for the century between 1800 and 1900, to track how the Industrial Revolution might have changed things.

1. The one thing we can all do is

to eat a plant based diet. It may well be to late for anything to turn the tide, but in terms of what is in our own control that’s it. Side benefits are huge health benefits like reversing and preventing heart disease, high blood pressure, most diabetes, and some cancers particularly breast cancer.
