Steven works on Climate Dynamics.

Current activities Steven is a senior research scientist within a group led by Nick Dunstone.  The group works to understand the mechanisms that drive regional climate variability in different parts of the globe.  Steven is currently carrying out research into the influence of the El Nino Southern

This page explains how we study extreme weather events, to see if climate change was a cause. These attribution studies help shape our understanding of climate change and its impacts.

gas emissions Sea surface temperature Topography Observations It’s important to understand these factors and how they influence a weather event. For example, natural climate variability and weather patterns are natural influences. Aerosols and greenhouse gases, though, are more affected by human

Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally.

Research led by the Met Office as part of the CSSP China project, has used a global Earth system model to investigate the impact of future changes in air pollutants on air quality and the climate.

, but it will still be very warm and humid where the sun comes out in the south and west of the UK. “In contrast to the last few days, maximum daytime temperatures will be reducing, with only isolated locations seeing temperatures of 30.0°C or above. And some northern and easterns areas much less warm

, temperatures may still reach the mid to high 20s. Conditions will remain humid, particularly in the south, with mostly light winds, though breezier conditions are possible in the far southwest. READ MORE: Climate change impacting the natural world Met Office presenter and meteorologist, Aidan

A direct link between climate change and drought is complicated by the many meteorological, hydrological, geological, and societal drivers that combine to cause droughts. However, there is increasing evidence that climate change is influencing rainfall patterns in many regions around the world
