Shouldn't there be more hurricanes, if man-made global warming is true?

no. man made global warming causes them to disappear during odd years. even years get the bad hurricanes.

unless, of course, we start getting a lot of hurricanes this year. in that case, the opposite applies.

what ever actually happens OR doesn't will be caused by global warming.

Hurricanes happen in cycles, and we are coming out of a slow cycle. That is a cycle with fewer hurricanes then normal and we are starting on a new cycle where we should see more hurricanes then normal.

Hurricanes happen when there is a difference in ocean temperature and air temperature the greater the difference the greater potential for a strong hurricane. If ocean and air temperatures are the same you don’t get hurricanes. So unless the ocean is warming faster then the air temperature, then global warming would mean weaker hurricanes. I haven’t seen any data on the rise of ocean temperatures compared with the rise in air temperatures, if someone has a link I like to read up on it. But from the information I have the air temperature is rising faster then ocean temperature, but I haven’t seen the data, their methods, etc.

Yes it makes SOME global warming people look like alarmists; namely the one’s who are on the news, saying the sky is falling. Some are very informed, and can show data, and are willing to discuss global warming in a rational matter some aren’t. But the same can be said for those who think global warming is bunk.

No, there should not be more hurricanes if global warming is true. All weather associated with rain on this planet, is primarily dependent on the difference of the temperature of the upper troposphere and the surface. Under an accelerated warming associated with increased CO2, the upper troposphere would be warmer because of an enhanced greenhouse effect, and there would less convection, to drive the hurricanes. That is why hurricane season does not peak until September. In July and early August the seas are very warm, but so is the atmosphere, only until mid August does the upper atmosphere begin to cool because of the Earth's axial tilt. However the oceans cool at a much slower rate.

Some of the most violent weather in the Solar system happens at temperatures well below the freezing point of water, it is all about gradients.

If you look at figure 16 in the link below, you will find that hurricane activity has not changed much over that last 50 years, if anything activity has declined.

Early predictions were made several decasdes ago and are fundementally correct, it was predicted there would be an increase in the number and intensity of storms. These same predictions appear in each of the IPCC reports, the first of which was published in 1990.

To eliminate anomalies over short periods of time climate is based on periods of 30 years and longer, in the last 30 years there has been a 50% increase in the number of storms and an 80% increase in intensity.

Global warming causes a slow and progressive change in the climate, over long periods of time many changes are observed including changes in storm patterns. 2005 was an exceptionally bad year, an anomaly even taking global warming into consideration. Fortunately such years are unlikely to occur again for a long time.

Last year was a quiet year, this year is average, the last three years as a whole are above average, so are the last 5, 10, 15 years...

One thing that's interesting is that the increase in storm activity is considerably beyond that which was predicted which has led some people to speculate that there may be other factors besides global warming involved.

We know the conditions in which hurricanes form and a warmer planet with warmer oceans makes an ideal spawning ground, it's to be expected that there will be a long term increase in numbers and intensities but one, two or even 10 years is too short a period of time to make any judgements.

The question assumes warming is man-made. Careful how you ask questions. Global warming is a fact. The amount humans contribute to global warming is debated.

Can hurricanes be a result of global warming? Absolutely. Heat is the driving force of hurricanes. Huricanes require special conditions to get started. It takes a series of synchronous events to drive a hurricane like Katrina. Study the perfect storm. Various weather events came together to create such a weather event. Hurricanes are like that, but most hurricanes fizzle out before threatening N. America.

The polar ice caps are melting. The earth's climate follows long cycles of warming and cooling. The seriousness of the melting poles and glaciers is underestimated. Humans depend very much on the snow and ice melt for fresh water.

The sea level is rising. An alarmist by nature is not looking at the long term. An alarmist wouldn't bother warning people for 4 decades.

The warming is so slow we believe we are immune to the consequences.

We are messing with Mother Nature and she will strike back. Every large natural cycle on the planet is being influenced by human activity.

Why are we not doing more to reduce greenhouse gas emissions? The population increase is exponential. Half of the world lives in poverty and long term strategies are not considered. The strategy is to burn the last tree like Easter Island. By 2050 there will be 9 billion people. Most of the large mammals will be extinct in the wild. People may need to purchase air to survive like we purchase water now.

No I think what it means is that we can expect stronger hurricanes. Global warming causes the icecaps to melt, cooling down the Atlantic making it harder to form them. But where the ocean depths are lower by the continents the hurricanes are developing and getting stronger quicker. We are now getting some subtropical depressions which are being created north of the tropics. It is not being alarmists, it is the ignorance of the people to accept what they are doing to the planet. Shall we talk about people with political agenda's? How about car manufacturers when there was the gas shortage in the 70's. Did they look for alternative fuel sources? No. The only reason they are doing so now is because the cost of fuel has sky rocketed and also because people are looking to save the planet. We might not be around for 200 years but I feel sorry for those children's children's children who will be if we don't start doing something now about it.

It isn't just hurricanes that we will be experiencing with global warming. Weather conditions will be more and more eratic, evidenced by hurricanes, typhoons, floods, droughts, earthquakes, mudslides, heavy rainfalls, more hail, tornadoes, later frosts and snow in spring, earlier frosts and snow in autumn, more heat waves, etc. These things are occurring now in more places than ever before.

Al Gore showed an informative chart on the Oprah show some time ago.

It showed that in the recorded history of the earth, we have always experienced the above weather catastrophes, but in the last 20-30 years these catastrophes are more seriously accelerated and widespread.

A comparison can be made between climate change and the labour pains of childbirth. At first, they are few and far between; as time passes, they become more and more severe and closer together, until the climax of birth.

The Global Warming prediction is not more hurricanes. It is that existing weather patterns will continue, but intensify. In the case of hurricanes that means we'll have years with a lot of activity and years with very little. that is what we've seen. The hurricanes that occur should be more energetic and that is also what we're seeing.

"Shouldn't there be more hurricanes, if man-made global warming is true?"

Your uneducated scientific ignorance is showing - look it up on Wikipedia.

Science keeps discarding old disproved theories all the time and making new ones to test. The current theory is that there will be about the same number, but on average there will be a larger number of stronger ones.

So, that's already to a pair volume and could increasingly extra impression our lives in extreme and gruesome techniques. and that i'm particular, you in addition to mght care approximately your babies and the flora and fauna on the planet as properly. desire that solutions your question. activities like this, upward thrust in sea stages etc. are what's assumed to be in shop already and we are able to could handle. yet far worse is feared (if the upward thrust in CO2 stages are no longer halted). Scientists think of we are close to to assorted ecological 'tipping factors', that when further on will improve up climate substitute. So, working example, large areas of permafrost interior the northern tundras at the instant are beginning up to thaw and launch methane. that's a effectual greenhouse gas and as this maintains, climate substitute will improve up. If those issues commence occurring too lots, we would be into 'run-away' climate substitute, and significant significant dramatic meltdown of our planetary ecological and climate platforms. which could be armaggedon and is what we could attempt to evade by taking action now. you're very incorrect. the full difficulty approximately climate substitute (that's extra beneficial than purely warming), is that the outcomes are concept to be already beginning. the hotter temperatures advise extra aggressive climatic circumstances, that's a clarification why the point of hurricanes, floods and different extreme climate activities are increasing (according to hazard you hadn't observed). those issues are very costly and significant and that's predicted that they are going to in user-friendly terms worsen interior the long-term (ignoring short-term flucuations in climate). So, working example, the prolonged heatwave in correct and southern Europe in summer season 2003 brought about the dying of 60,000 human beings (or some thing around that) and expected crop losses have been c.$12.3 bn. Such activities are predicted to extend one hundred-fold over the subsequent 4 many years, so as that by the 2040s extra beneficial than 0.5 the summers could be warmer than 2003.
