Hey Pommiegranite dont get lumping me in with the Brummies,I"m from the posh bit of the Midlands-Wolverhampton!Lol
My point wasn't about doubting climate change but about what constitutes proof of it happening.smurf - I'm amazed that there's doubt being expressed about climate change here
ok m8 -1. My point wasn't about doubting climate change but about what constitutes proof of it happening....
2. ... Likewise if a tropical cyclone hits the South Island of New Zealand or Tasmania then that would also strongly suggest something has changed. And it would be consistent with climate change. So would snow on the city streets of Darwin.
3. But this nonsense of saying one severe weather event is proof of climate change is doing more harm than good IMO. At best it looks alarmist. More to the point, it shows a total disregard for proper science in what is ultimately a scientific issue.
4. ..... If you want some reasonable proof then look at the rainfall decline in SW WA that's been going on since the mid-1970's. And then maybe start wondering why Tas has been dry since 1982 apart from a wet period mid-1991 to spring 1997. Or why the humidity is increasing globally. Those things suggest the climate is changing. One flood doesn't. That's my point.
5. Personally I think climate change is real.
6. But that said, there's never a reason to abandon proper scientific processes and stop thinking as many seem to want us all to do over this issue.
Is global warming changing the intensity or frequency of hurricanes?
Intensity: According to the 2007 Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC-AR4), it is “more likely than not” (better than even odds) that there is a human contribution to the observed trend of hurricane intensification since the 1970s. In the future, “it is likely [better than 2 to 1 odds] that future tropical cyclones (typhoons and hurricanes) will become more intense, with larger peak wind speeds and more heavy precipitation associated with ongoing increases of tropical [sea surface temperatures].”
Frequency: According to the IPCC-AR4, on a global scale, “[t]here is no clear trend in the annual numbers [i.e. frequency] of tropical cyclones.” As discussed above, however, the frequency of tropical storms has increased dramatically in the North Atlantic. Reasons for this increase are currently subject to intense debate among climate scientists. At least two recent peer-reviewed scientific studies indicate a significant statistical link between the increased frequency and global warming, but research to identify a mechanism explaining this link is ongoing.
Is global warming generating other types of severe weather?
Global temperature has increased and precipitation patterns have changed over the 20th century as a result of human-induced global warming, resulting in some increases in extremes of temperature and precipitation. According to the IPCC-AR4, “increases in the amount of precipitation are very likely [better than 9 to 1 odds] in high-latitudes, while decreases are likely [better than 2 to 1 odds] in most subtropical land regions,” and “it is very likely [at least 9 to 1 odds] that hot extremes, heat waves, and heavy precipitation events will continue to become more frequent.”
Will the damages from severe weather become worse in coastal regions?
The biggest reason for increased loss of life and property in coastal regions is population growth and increasing development in coastal areas. As growth and development continue, the damages caused by severe weather will increase regardless of global warming. It stands to reason that climate change, namely sea level rise and increases in tropical storm activity, would exacerbate the damage as global warming continues.
What can we do to reduce the consequences and costs of severe weather events?
It is clear that the United States is not prepared to handle multiple catastrophic events in a short time period, and many other countries are even less capable of bearing the economic and logistical burdens of catastrophic weather events. We probably will never be completely prepared, but we could do better. We can plan our communities better, we can design our buildings and infrastructure better, and we can manage resources better. Steps taken today to reduce future greenhouse gas emissions will limit the effort necessary to adapt to climate change that will inevitably result from global warming
As low-lying islands lacking a surrounding shallow shelf, the island communities of Tuvalu are especially susceptible to changes in sea level and storm patterns that hit the island undissipated. It is estimated that a sea level rise of 20-40 centimetres (8-16 inches) in the next 100 years could make Tuvalu uninhabitable.[2][3] The South Pacific Applied Geoscience Commission suggest that while Tuvalu is vulnerable to climate change, there are additional environmental problems such as population growth and poor coastal management, which are affecting sustainable development on the island, they rank the country as extremely vulnerable using the Environmental Vulnerability Index.[4]
While some commentators have called for the relocation of the population of Tuvalu to Australia, New Zealand or Kioa (Fiji), the former Prime Minister Maatia Toafa said his government did not regard rising sea levels as such a threat that the entire population would need to be evacuated.[5][6] In spite of persistent internet rumours that New Zealand has agreed to accept an annual quota of 75 evacuees, the annual residence quota of 75 Tuvaluans under the Pacific Access Category (and 50 places for people from Kiribati) replaced the previous Work Schemes from the two countries and are not related to environmental concerns.

Maybe these youtubes will answer your questions lusk. ( I suspect you and Wayne may not have gone back far enough in the posts.smurf - I'm amazed that there's doubt being expressed about climate change here

Up to 10,000 dead in cyclone-hit Bangladesh: officials Officials say up to 10,000 people are dead and millions homeless and hungry in cyclone-hit Bangladesh, as the army and aid workers battled to reach the devastated coast.
Three days after cyclone Sidr tore into one of the world's poorest nations from the Bay of Bengal, rescue workers were still fighting their way through a landscape of flattened villages and traumatised crowds.
