The strength and path
of the North Atlantic jet stream and the Greenland blocking
phenomena appear to be influenced by increasing temperatures in the Arctic which have averaged at least twice the global warming rate over the past two decades, suggesting that those marked changes may be a key factor affecting
extreme weather conditions over the UK, although an Arctic connection may not occur each year.
During periods
of extreme dry
weather caused by El Niño and a
phenomenon called the positive Indian Ocean Dipole, smoke emissions are considerably higher — either because farmers are taking advantage
of the dry
weather to burn more land or because once burning, the fires are more difficult to control.

extreme weather events and it's this kind

phenomenon and any
phenomenon of greater severity or frequency
of extreme weather events.
This result would be strongly dependent on the exact dynamic response
of the Greenland ice sheet to surface meltwater, which is modeled poorly in todays global models.Yes human influence on the climate is real and we might even now be able to document changes in the behavior
of weather phenomena related to disasters (e.g., Emanuel 2005), but we certainly haven't yet seen it in the impact record (i.e., economic losses)
of extreme events.

In recent decades, this warming was accompanied by the constant rising
of the sea level, and it is also hard not to relate it with the rise in
extreme weather events, regardless
of the fact that we can not attribute a scientifically determined cause to each
phenomenon in particular.

extreme weather phenomena are increasing because
of global warming.)
For example, let's say that evidence convinced me (in a way that I wasn't convinced previously) that all recent changes in land surface temperatures and sea surface temperatures and atmospheric temperatures and deep sea temperatures and sea ice extent and sea ice volume and sea ice density and moisture content in the air and cloud coverage and rainfall and measures
of extreme weather were all directly tied to internal natural variability, and that I can now see that as the result
of a statistical modeling
of the trends as associated with natural
phenomena.

of hazardous
phenomena (
extreme weather), followed by impact assessment and closed by mitigation and risk control measures.

Most key vulnerabilities are related to (a) climate
phenomena that exceed thresholds for adaptation, i.e.,
extreme weather events and / or abrupt climate change, often related to the magnitude and rate
of climate change (see Box 7.4), and (b) limited access to resources (financial, technical, human, institutional) to cope, rooted in issues
of development context.
