Prof. Camilo Mora: 'The actual writing of the paper took us about two months. It’s 40 pages altogether. But it’s amazing that the press release on this paper took us two months to prepare. It was a massive investment of time for just two pages of paper. So another limitation for us as scientists is that it’s very hard for us to commit that kind of time to prepare for that press release.'
What motivates Mora? 'My motivation and everybody’s motivation whenever we produce these papers is trying to increase the level of awareness of people and politicians to take action on these things...So as scientists, we are struggling to figure out how we can increase public awareness on this issue.'
Mora, a University of Hawaii biogeographer, ecologist, and climate modeler. 'By the year 2047 the climate is going to move beyond something we’ve never seen in the last 150 years.' - 'All the species in the tropics are going to suffer quite dramatically' - 'What I’m suggesting is to inform people about the environmental and social costs of having a child.'
From 80,000 to 12,000 years ago, when CO2 concentrations lingered near or below 200 ppm, many new or recent studies suggest that when directly comparing region to region, it was as much as 6°C warmer than today even during this ice age period. This has prompted some scientists to “exclude atmospheric pCO2 as a direct driver of SST [sea surface temperature] variations”.
Sean Sublette, a meteorologist at Climate Central, who pointed out that the 1960s through 2010s saw between one and three storms each decade before the June 1 start date on average. It might be tempting to ascribe this earlier season entirely to climate change warming the Atlantic. But technology also has a role to play, with more observations along the coast as well as satellites that can spot storms far out to sea.
“I would caution that we can’t just go, ‘hah, the planet’s warming, we’ve had to move the entire season!’” Sublette said. “I don’t think there’s solid ground for attribution of how much of one there is over the other. Weather folks can sit around and debate that for awhile.” Earlier storms don’t necessarily mean more harmful ones, either.
"Hotter long-term temperatures have already had a negative impact on the diet diversity of children all across the world. The researchers found that hotter temperatures, both long-term averages and short-term anomalies, were significantly correlated with low diet diversity in five of the six regions studied."
