Prehistoric creatures flocked to different latitudes to survive climate change – the same is taking place today

Studies looking at the evolution of biodiversity by latitude have shown that during some intervals in Earth’s history, species biodiversity was actually highest at latitudes far from the equator.

Understanding why latitudinal biodiversity has shifted over hundreds of millions of years, often linked to mass extinction events, is critical in today’s world, where we’re facing climate change, habitat loss and decreasing biodiversity worldwide. Looking back in geological time reveals an alarming picture of what we’re set to lose if we fail to address increasing global temperatures.

Modern biodiversity peaks in low-latitude equatorial regions, such as in the tropical rainforests of the Amazon and central Africa. This pattern is more likely to be recorded during “icehouse” times, when ice sheets are present in both poles simultaneously – like today.

During warmer intervals, called “hothouse” or “greenhouse” Earth states, bimodal peaks have been recorded. This means there were two bands where biodiversity was highest, and these wrapped around the Earth at mid-latitudes, or regions sitting between 25° and 65° north and south of the equator.

...

insights into past mass extinction events are critical for understanding how Earth’s current patchwork of biodiverse regions could change. As global temperatures continue to rise, some studies have predicted that species will disperse towards the poles from equatorial regions – but if the pace of change is too rapid, they risk going extinct.

Others suggest that global warming might lead to the climate becoming more similar across different latitudes, potentially producing a peak in biodiversity at mid-latitudes. There’s already evidence that marine latitudinal biodiversity has become increasingly bimodal over the last 50 years.

With a possible “sixth mass extinction” looming, or even already taking hold, a long-term perspective will be critical for understanding how to sustain Earth’s biodiversity into the future.

Pumping wells, water levels, and basins in California's Central Valley. (a) Well purposes, categorized on the basis of information recorded in the “Planned Use/Former Use” field of California's well completion database for those well completion reports meeting our quality control criteria for analysis (supporting information section S1). Most categorized wells have been constructed for either domestic (DOM) or agricultural use (AG), with a smaller share constructed to supply water to industry (IND). (b) Recorded well depths for those well completion reports meeting our quality control criteria for analysis (supporting information section S1). Well depths are generally shallower in the north and deeper in the south. (c) Well water level measurements made between 2013 and 2018. Like well depths, well water levels tend to be shallower in the north and deeper south. (d) Groundwater basins delineated by California's Bulletin 118, provided for context (Wyckoff & Floyd, 2016); yellow indicates basins deemed critically overdrafted, and green indicates basins not deemed critically overdrafted.

SEJDA: asi zalezi od lokality, co chodim kazdy rok zbierat odpadky okolo vesnice, tak brciek som teda moc nenasiel, zato petky sa tam kazdy rok zjavia v hojnom pocte aj na miestach vyzbieranych rok predtym, tak s tym zbieranim to asi nie je take zhave, najhorsie ked ich hodia pod nejaky ruzovy krik, to sa tam vselijako plazis, aby ta to nedoskrabalo :)

SEJDA: proboha, já nejsem fanoušek plastových brček... já jen konstatuju, že jejich obsah v atmosféře je minimální a na globální oteplování nemají vliv :-) téma znečištění prostředí a téma klimatické změny nejen, že jsou mimoběžný, ale částečně jdou proti sobě. plastový odpadky, který neproženeme spalovnama, ve skutečnosti nepřispějou k růstu CO2 (max. mírně zlevňujou benzín a naftu, protože co si budeme povídat, plasty jsou částečně odpad při výrobě pohonných hmot z ropy - jinak by nebyly tak levný, pochopitelně..)

DZODZO: plastovou lahev sebere kazdy i poloslepy, brcko uz tak snadno nenajdes, takze to byly brcka.

SEJDA: ja si tipnem ze to neboli plastove brcka ale PET lahve, ak ano mozeme to dat ako podnet pre tych lobistov zo zalohujme.cz, ze si ich tam mozu ist vyzbierat, ze sa im to oplati :)))

Ropný trh má být dle predikce analytiků společnosti Goldman Sachs v deficitu 5 milionů barelů ropy za den (bpd), a to do konce letošního roku. V komentáři pro agenturu Reuters pak analytici dále uvedli, že ropná poptávka má v druhé polovině roku 2021 vzrůst o dalších 2,2 mil. bpd.
