floods and droughts are cyclical phenomena-global warming not to be blamed?

Question

how is this piece of news being used by various organs of our society?

Answer 1

floods and droughts are sign of global warming, just listen to the "experts"

the waters have beeeen succesfully muddied.

no matter what happens, normal or abnormal, it's caused by global warming.

Answer 2

It may not seem much right now but it is more than usual. Have you ever seen this many floods and droughts in your entire life? Doesn't it appear strange that floods and droughts are happening with more frequency? Don't they seem more severe now than at any other point in history? Look at the news and notice how many deaths are being reported. How many places have been devastated. You will realize that what we have is greater severity and frequency. It may not seem much but as time goes by, it will be more and more noticeable. The effects of global warming are slow at first but will pick up speed. It is predicted that the effects of global warming will be increasing around the year 2009. The years that follow will leave no doubt about global warming. We must make concrete steps now because if we wait for absolute proof it will be far too late.

Answer 3

Simply saying that floods and droughts are cyclical is over-simplifying a complex issue and fails to address many key points concerning global warming.

All weather related events are to some extent cyclical because there are a series of cycles that govern our climate. Climate cycles are progressive but extremely slow, occurring as they do over periods of many thousands and millions of years.

Our position within these cycles is such that we shouldn't be having nearly as many floods and droughts as we are doing. It's much too simplistic to simply say it's due to natural cycles.

It's also too simplistic to blame global warming. As with anything relating to the weather and climate there are a great many factors that need to be taken into account and no one factor can be singularly blamed for what's happening.

Along with global warming we need to consider the effects that agricultural practices, urbanisation, deforestation etc have with respect to flooding and droughts.

I haven't come across this being reported recently in the news, if it has been then it's an inaccurate and irresponsible piece of journalism in that it attempts to explain away an important and complicated issue with a simple and unsatisfactory explanation.

Answer 4

Well, about all the "use" its going to get is that the so-called"skeptics" will use it to further demonstrate they don't understand science.

There are many factors influencing weather--not just global warming. Among these are short-and-long term cylicial patterns. These occur naturally. The current drught in the Southwest appears to be another one of these.

What do scientists actually say? (not the hype). Simple: at this point in time we are beginning to see the earliest effects of climate changes caused by global warming. It is possible-in fact it is likely--that these draughts, the increase in frequency of severe hurricanes, etc. are PARTIALLY due to global warmings early-stage effects. But this has not been established with certainty yet. What we do know is that--as global warming worsens, these are the kinds of effects we will continue to see more and more of in the future, as the influence of rising temperatures becomes greater.

Answer 5

sure, those are organic happening phenomena, no longer something to argue approximately there. What worldwide warming does is it truly is almost a clean layer on suitable of that, affecting what's certainly happening (arguing that GW is anthropogenic). the ambience can carry greater water vapor whilst it gets warmer. The greater advantageous temperature the precipitation, the two from land, and oceans. whilst the soils dry up, you get drought. The greater advantageous fee of the water cycle acts to the two develop droughts and downfall. It complements the underlying form of that section, or, each and every so often, alter it. the place there is drought the greater advantageous evaporation fee from soils will enhance those developments. the comparable with flooding. i do no longer understand which component you will take, so making waiting questions isn't person-friendly.

Answer 6

Weather is impacted by three things, air, water vapour and temperature. Our weather is not cyclical, it is the result of human activity.

California just had power losses and deaths by treating the symptom of heat waves. The same UV that burns our skin is in effect burning buildings and generating heat they aren't designed for. California used air conditioning to treat the heat symptom which is really refrigeration that uses thousands of watts per hour. The generated heat from the buildings is as high as 200 degrees F on a 92 degree day, that is a massive heat gain not involving a natural cycle.

Answer 7

It's complicated.

Short term weather is not the same thing as long term climate. But climate affects weather.

You can't point to any one flood or drought and say it's proof (or disproof) of global warming.

But global warming will change patterns of precipitation. So, over the long run, areas are very likely to see either more or less rain that they're used to.

That means areas will see more floods and droughts over the long run. Irrigation systems will need to be redesigned and rebuilt.
