• HadGEM1: Met Office climate prediction model

  HadGEM1 is the first in a new generation of coupled climate models incorporating a non-hydrostatic, fully compressible, deep atmosphere formulation with a semi-implicit semi-Lagrangian time integration scheme.

  Note that the most recent HadGEM model is the HadGEM3 HadGEM1 stands for the Hadley Centre Global Environment Model version 1. It was developed in 2006 and used in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change. The atmospheric component has 38 levels extending

• World’s oceans capturing unrelenting climate change

  The world’s oceans are charting the unrelenting progress of climate change says a new global report: The State of the Climate in 2021.

  The 32nd annual State of the Climate report – published today by the Bulletin of the American Meteorological Society – shows that two marine-related measures – ocean heat content and global sea level rise – were the highest on record last year. Scientists measure climate change by a number

• Understanding one of Europe's biggest climate drivers

  A new Met Office-led study – reviewing evidence from previous scientific papers and climate models – reveals natural patterns of weakening and strengthening of ocean currents which influence the UK’s weather and climate.

  In the North Atlantic lies one of the world’s largest climate mechanisms: a system of currents transporting relatively warm water from the tropics to the poles, with return currents at depth transporting colder, denser water further south. The transport of heat to the North Atlantic keeps the UK’s

• Creating a five-year window into future climate

  Providing annually-updated five-year climate predictions at global and continental scales is the focus of a new international science collaboration co-ordinated by the WMO and led by the UK’s Met Office.

  (1850-1900). The last five-year period has been the warmest five years on record.  This year’s five-year climate forecasts predicts that: there is now a 20% chance of the world temporarily reaching 1.5 C above pre-industrial levels in one of the next five years there will be further enhanced warming of the Arctic compared to other regions increased risk of storminess across the Atlantic basin
