Assuming el nino ends, it should be a bit cooler once that happens. But eventually neutral or la nina years will surpass this year's heat.

Though considering the 20 - 30 year lag between creating emissions and feeling their impact, we've still got at least a decade of accelerating heating before it settles into a more constant increase corresponding with emissions plateauing in the 2010s--oh nm, that was just a temporary plateau, it started increasing again during the late 10s. But maybe we're at the peak now and will see the acceleration of heating stop in 20 - 30 years.
