A comprehensive meta-analysis of global terrestrial and marine genetic diversity covering more than three decades of research demonstrates rapid loss of genetic diversity and identifies conservation i...

Two new research papers show the downsides of upsizing our vehicles. SUVs have a disproportionate impact on traffic jams, and they injure more people than cars

The celebrated presenter warns of ‘modern day colonialism at sea’ as he highlights the destruction caused by overfishing and bottom trawling

Industrial fishing has caused immense damage to ocean life, but given the right protection, the sea has miraculous powers of recovery.

Summer 2024 was exceptionally warm in northern Fennoscandia, with June-August mean temperatures at several long-term weather stations surpassing the long-standing record set in 1937. In this region, summer mean temperatures have been reconstructed from tree-ring proxies, which provide annually resolved and millennium-long records of past climate. Here we show, using in-situ observations and two different tree-ring reconstructions, that summer 2024 was the warmest summer in 2000 years in northern Fennoscandia. Employing an attribution method based on Coupled Model Intercomparison Project Phase 6 climate models, we further estimate that climate change increased the likelihood of this extreme season by a factor of 93 (5–95% uncertainty range 19–881) and increased the temperature an additional 2.1 °C (1.4–2.8 °C). Atmospheric circulation patterns influencing both summers 1937 and 2024 were largely similar, suggesting a comparable large-scale circulation influence. Our findings highlight the impact of climate change for the contemporary heat extremes in Fennoscandia, indicating that the warming of summer climate is emerging from its range of natural climate variability over the last two millennia.

Protists are polyphyletic singled-celled eukaryotes that underpin global ecosystem functioning, particularly in the oceans. Most remain uncultured, limiting investigation of their physiology and cell ...

The threshold has been exceeded for only one year so far, but humanity is nearing the end of what many thought was a ‘safe zone’ as climate change worsens.

Climate shapes the biogeography of microbial and viral communities in the ocean. Among abiotic factors, temperature is one of the main drivers of microbial community distribution. However, we lack kno...
