Recent marine heatwaves in the North Pacific warming pool can be attributed to rising atmospheric levels of greenhouse gases

چکیده
Abstract Over the last decade, northeast Pacific experienced marine heatwaves that caused devastating ecological impacts with socioeconomic implications. Here we use two different attribution methods and show forcing by elevated greenhouse gases levels has virtually certainly multi-year persistent 2019–2021 heatwave. There is less than 1% chance event ~3 years duration 1.6 ∘ C intensity could have happened in absence of forcing. We further discover recent are co-located a systematically-forced outstanding warming pool, which attribute to industrial aerosol-load decrease. The here-detected long-term pool associated strengthening ridge high-pressure system, recently emerged from natural variability climate indicating they will provide favorable conditions over for even more severe heatwave events future.

متن کاملAtmospheric footprint of the recent warming slowdown
Growing body of literature has developed to detect the role of ocean heat uptake and transport in the recent warming slowdown between 1998-2013; however, the atmospheric footprint of the slowdown in dynamical and physical processes remains unclear. Here, we divided recent decades into the recent hiatus period and the preceding warming period (1983-1998) to investigate the atmospheric footprint....
متن کاملAtmospheric aerosols versus greenhouse gases in the twenty-first century.
Looked at in a simplistic way, aerosols have counteracted the warming effects of greenhouse gases (GHG) over the past century. This has not only provided some 'climate protection', but also prevented the true magnitude of the problem from becoming evident. In particular, it may have resulted in an underestimation of the sensitivity of the climate system to the effect of GHG. Over the present ce...
