Sentences with phrase «term changes in rainfall»

While there may be long term changes in rainfall, blaming it on global warming is premature, especially since long term drought happened in the west well before the industrial age.

Pilot study focusing on a region vulnerable to climate change Although the study highlights that long term changes in rainfall intensity are not always» man - made,» it does not necessarily mean that today's weather anomalies across the Indian Ocean rim countries and, in particular, their frequency, are not subject to human influence.

So if you think of going in [a] warming direction of 2 degrees C compared to a cooling direction of 5 degrees C, one can say that we might be changing the Earth, you know, like 40 percent of the kind of change that went on between the Ice Age; and now are going back in time and so a 2 - degree change, which is about 4 degrees F on a global average, is going to be very significant in terms of change in the distribution of vegetation, change in the kind of climate zones in certain areas, wind patterns can change, so where rainfall happens is going to shift.

One of the most striking signals of change emerged over Australia, where a long - term decline in fall and winter rainfall has been observed over parts of southern Australia.

However, shifts in the average climate of the tropical oceans could change the relative amounts of expansion in these two adjoining oceans, and ultimately modulate the long - term change in the IPWP impact on regional rainfall amounts.

Scientists at the University of Sydney have analysed up to 22 years of long - term monitoring data on plants and animals in central Australia to project how changing rainfall and wildfire patterns, because of climate change, will influence desert wildlife.

For significant periods of time, the reconstructed large - scale changes in the North Pacific SLP field described here and by construction the long - term decline in Hawaiian winter rainfall are broadly consistent with long - term changes in tropical Pacific sea surface temperature (SST) based on ENSO reconstructions documented in several other studies, particularly over the last two centuries.

In the long term, changes in sea level were of minor importance to rainfall patterns in north western Sumatra With the end of the last Ice Age came rising temperatures and melting polar ice sheets, which were accompanied by an increase in rainfall around Indonesia and many other regions of the worldIn the long term, changes in sea level were of minor importance to rainfall patterns in north western Sumatra With the end of the last Ice Age came rising temperatures and melting polar ice sheets, which were accompanied by an increase in rainfall around Indonesia and many other regions of the worldin sea level were of minor importance to rainfall patterns in north western Sumatra With the end of the last Ice Age came rising temperatures and melting polar ice sheets, which were accompanied by an increase in rainfall around Indonesia and many other regions of the worldin north western Sumatra With the end of the last Ice Age came rising temperatures and melting polar ice sheets, which were accompanied by an increase in rainfall around Indonesia and many other regions of the worldin rainfall around Indonesia and many other regions of the world..

The climate change effect is probably only a 5 to 10 % effect in terms of the instability and subsequent rainfall, but it translates into up to a 33 % effect in terms of damage.

Of course, as they point out «because rainfall is such a variable element, trend values are highly dependent on the start and end dates of the analysis» and the fact they are simply using linear interpolation it is very difficult to derive anything meaningful in terms of climate change from just one map.

Given a reduction of 10 years in rainfall what is the posterior probability of it being a short - term departure, long - term but temporary departure and / or change.

Could they produce sets of weather - maps that if somehow integrated over 30 years could produce a «supermap» showing actual climate change in terms of e.g average windspeeds, rainfall, cloud - cover, pressure and so on?

Once this La Nina faded, sea levels rebounded sharply, and that rise might have been incorrectly interpreted as some rapid acceleration in the long - term sea level rise, when in fact, mass was shifting back from land to ocean as rainfall patterns changed once more, but also much of the excess water on the land was draining back to the oceans.

Jeff Knight said: «Our analysis shows that climate change likely did make a contribution to the record rainfall in 2013 - 14 through a long - term increase in UK winter rainfall that is not associated with changing weather patterns.

While the correlation displays decadal - scale variability similar to changes in the interdecadal Pacific oscillation (IPO), the LDSSS record suggests rainfall in the modern instrumental era (1910 — 2009 ad) is below the long - term average.»

For example, responses to recent historical climate variability and change in four locations in southern Africa demonstrated that people were highly aware of changes in the climate, including longer dry seasons and more uncertain rainfall, and were adjusting to change through collective and individual actions that included both short - term coping through switching crops and long - term adaptations such as planting trees, and commercialising and diversifying livelihoods (Thomas and Twyman, 2005; Thomas et al., 2005).

Overall, our results suggest that changes in the SAM may be partly responsible for the current decline in winter rainfall in southern South Australia, Victoria, and Tasmania, but not the long - term decline in southwest Western Australian winter rainfall».

The expected response to a step increase in CO2 is to move from the relatively stable Holocene climate through a period of rapid (in geological terms) change to a new, relatively stable climate with a higher overall temperature and somewhat different circulation and rainfall patterns.

Even without the new factor of a changing climate, it is time to acknowledge that California is in permanent long - term shortage: even in a «normal» rainfall year more water is now demanded and used than nature provides, leading to growing political conflict, unsustainable groundwater overdraft, and ecological destruction of the state's rivers, streams, and wetlands.

This comes in terms of the lack of water from glacial melt, or changes in disease vectors, or rainfall patterns, or the lodge pole pine being killed off by beetles in million - acre swaths.
