When a climate Cause extreme has an adverse impact on human welfare, it becomes a climatic disaster. [ ENCY 0 MCLH 24/06/2014 ]

Natural variability in the climate often produces extremes in the weather Cause . [ ENCY 0 MCLH 24/06/2014 ]

In addition, given the large natural variability in climate and the general rarity of climatic Cause extremes it is hard to determine whether they are now occurring as a result of global warming. [ ENCY 0 MCLH 24/06/2014 ]

It is the extremes in rainfall and temperature Cause which most affect humans, provoking floods, landslides, drought and shifts in the seasons which affect food production and tourism. [ AWORLDOFSCIENCE 0 MCLH 24/06/2014 ]

The best information that they can provide relates to changes in extremes that occur on a large spatial scale, like those for temperature or wind speeds, and they can also provide useful information about the direction of change in extremes of other climate variables Cause . [ 3CANADAENVIRON 0 MCLH 24/06/2014 ]

A climate Cause extreme then, is a significant departure from the normal state of the climate, irrespective of its actual impact on life or any other aspect of the Earth 's ecology. [ ENCY 0 MCLH 24/06/2014 ]

While extreme minimum temperatures Cause will generally become more moderate in a warmer climate, extreme maximum temperatures can also be expected to become hotter. [ 1CANADACCD 0 TK 09/07/2013 ]

Extreme events Cause include, for example, floods, soil moisture deficits, tropical cyclones, storms, high temperatures, and fires. [ CHANG 3IPCCCONSEQUENCE 0 TK 09/07/2013 ]

Most studies indicate that, on average, extreme precipitation events Cause will become more frequent. [ CHANG 5CANADAICC 0 TK 09/07/2013 ]

Extreme weather Cause is also potentially destructive, although not all extreme weather events end in disasters. [ CHANG 2CANADACCD9801 0 TK 09/07/2013 ]

The west coast often is buffeted by storm surges and currently is at risk from erosion, inundation and extreme storm events Cause . [ CHANG 7IPCCREGION 0 TK 09/07/2013 ]

Other uncertainties include the magnitude and persistence of effects of rising atmospheric CO2 on crop yield under realistic farming conditions; potential changes in crop and animal pest losses; spatial variability in crop responses to climate change; and the effects of changes in climate variability and extreme events Cause on crops and livestock. [ CHANG 3IPCCCONSEQUENCE 0 TK 09/07/2013 ]

In the Arctic, where average annual temperatures are projected to warm by 10 - 20 ° C during the last half of the century, extreme minimum temperatures Cause over open waters are expected to moderate considerably. [ CHANG 1CANADACCD 0 TK 09/07/2013 ]

Extreme climatic events Cause are those that are rare both in their intensity and in the frequency of their occurrence. [ CHANG 1CANADACCD 0 TK 09/07/2013 ]

These extreme wet events Cause are balanced by extreme dry events in other regions. [ CHANG 3CANADAENVIRON 0 TK 09/07/2013 ]

These extreme events Cause may simply be the result of natural variations in climate. [ CHANG 6CANADAQFP 0 TK 09/07/2013 ]

Direct health impacts from climate change are likely to arise from the increased occurrence and magnitude of extreme weather events Cause . [ CHANG ENCY 0 TK 09/07/2013 ]

Conversely, the frequency and magnitude of extreme low temperature events , such as cold spells Cause , is projected to decrease in the future, with both positive and negative impacts. [ CHANG 3IPCCCONSEQUENCE 0 TK 09/07/2013 ]

The difficulty is that we don't know for sure the extent to which the present wave of extremes is a natural climatic phenomenon, nor do we know the real potential for the intensification of extreme weather Cause in a warmer climate. [ CHANG 2CANADACCD9801 0 TK 09/07/2013 ]

However, even in these regions, such benefits can be more than offset by other stresses, such as more frequent and sustained periods of extreme heat and drought Cause or the effects of intense rainfall events and related floods. [ CHANG 5CANADAICC 0 TK 09/07/2013 ]

Studies suggest that the frequency and severity of many types of extreme weather events Cause that cause disasters will change as the climate warms. [ CHANG 3CANADAENVIRON 0 TK 09/07/2013 ]

The amplitude and frequency of extreme precipitation events Cause are very likely to increase over many areas and thus the return periods for extreme precipitation events are projected to decrease. [ CHANG 2IPCCBIODIVERSITE 0 TK 09/07/2013 ]

The mean temperature may increase, increasing the probability of extreme hot days Cause . [ CHANG 3CANADAENVIRON 0 TK 09/07/2013 ]
