Climate scientists warn ‘greenhouse’ changes will cause Earth temperatures to spike


A high-fidelity recording of our planet’s temperature variations was created and revealed this week, spanning 66 million years in the past. This timeline is the most comprehensive record of its kind, showing the global average temperatures of our planet, showing four significantly different states. These states were called Hothouse, Warmhouse, Coolhouse, and Icehouse.According to the research paper released this week, “Here we present a new, continuous, highly resolved, astronomically dated composite of isotope records of benthic foraminifers developed in our laboratories. Each of the four states has its own set of responses to orbital variations. Each of these answers results in small changes in global temperatures VS giant changes between each of the four climate states.

“As we rebuilt the climates of the past, we’ve seen some rough long-term changes pretty well. We also knew that there should be smaller scale rhythmic variability due to orbital variations, but for a long time it was considered impossible to recover this signal, ”said James Zachos, professor of Earth Sciences and planets at UC Santa Cruz.

“Now that we have successfully captured the natural variability in climate, we can see that the projected anthropogenic warming will be much greater than that. Take a look at the big chart below and see if you can spot the latest trend. (Westerhold et al., CENOGRID)

According to Zachos, the IPCC projections in their “business-as-usual” scenario for the year 2300 will potentially cause global temperatures to skyrocket. Projections from research released this week suggest that global temperature could “bring global temperature to a level the planet has not seen in 50 million years,” Zachos said.
