to understand and communicate as including emissions scenarios require additional explanation. It also allows for simpler comparisons across different models and lines of evidence, as it helps to reduce the influence of some uncertain factors (e.g. the large-scale sensitivity of climate models to increasing

pressure was present over Atlantic Canada and Greenland. This region of high pressure influenced the path of Hurricane Sandy, causing it to make an unusual turn to the northwest before making landfall along the northeast coast of the US. The 2012 season was characterised by a high level of early season

important regions within the domain and c) to provide an estimate of the run time (or rate of simulation). The results of these tests then allow a suitable domain to be chosen.

is because of the slow response time of some elements of the climate system, such as the oceans with their large thermal capacity. Climate simulations show that it can take several centuries for the climate system to reach equilibrium, all other external forcings remaining constant (e.g. volcanoes, Sun

for Emission Modelling). The estimates are presented as yearly averages and are compared to the United Nations Framework Convention on Climate Change (UNFCCC) inventory. The atmospheric measurements and emission estimates of greenhouse gases provide an important cross-check for the emissions inventories

contributed towards the cooling period including significant volcanic eruptions, cyclical lows in solar radiation, changes in ocean circulation and the natural variability of the global climate. Whatever the cause of the cooling winters were generally more severe. The Thames froze on a number of occasions

often asked about climate change is whether the changes we are seeing in the earth’s climate are due to human influence such as greenhouse gas emissions, or if they can be explained by natural causes such as changes in solar activity or volcanic eruptions. The Climate Science for Service Partnership
