Am I still allowed to question climate change?

Sunspots and variable radiation from the sun may also have a significant effect.

 

Yep, Sunspot activity has dropped off to its lowest point in over 100 years, its the quietest sun we've seen in almost a century.

Windpower generation of energy is extremely expensive.

Solar-power generation of energy isn't.

 

Wind generation is also extermely ugly, a complete blight on the landscape.

Solar isn't very efficient, and to us not a commercial go-er

 

Water, now we've got plenty of water and lots of coastline.

The Feverish Hunt For Evidence Of A Man-Made Global Warming Crisis

It appears to be where I would expect to find it, which is also the region that is warming the most.

 

Permafrost zones occupy up to 24 per cent of the exposed land area of the Northern Hemisphere. Permafrost is also common within the vast continental shelves of the Arctic Ocean. This subsea permafrost formed during the last glacial period when global sea levels were more than 100 m lower than at present and the shelves were exposed to very harsh climate conditions. Subsea permafrost is slowly thawing at many locations. Permafrost of various temperatures and continuity also exists in mountainous areas, due to the cold climate at high elevations.

I rely on common sense and the evidence presented by others which is consistent with my scientific knowledge.

1, The bits of permafrost where an icrease of a few degrees will cause it to melt are the bits around the edges of the stuff. Whilst that would be significant, it's of the order of 1cm sea level rise. It's also been included in the IPCC's estimates. Do you know more than they do?

 

2, Undersea ice will not cause any significant sea level rise if it melts. It might cause a tiny sea level reduction. Ice being of greater volume than water.

 

Does this cause any trouble with your basic common sense and knowledge of science. I hope it does not as it's very basic.

And yet without it, it would be too cold for us to exist.

Hi Max.

 

Do you consider the relationship between CO2 concentration and temperature to be linear?

Global warming is the real threatening issue for all human being on the earth.

Its a big issue and I think will badly destroy natural environment.

We are also maaging to wipe out many species, large and small. I personnly think that is a bigger issue because we can do something about it. The answer to climate change does not lie in reducing our personal co2 footprints, but reducing the worlds population. Not an easy task, and we are probably too late.

Hi Max.

 

Do you consider the relationship between CO2 concentration and temperature to be linear?

 

The linear trend from August 1997 (in the middle of an exceptionally strong El Nino) to August 2012 (coming at the tail end of a double-dip La Nina) is about 0.03°C/decade, amounting to a temperature increase of 0.05°C over that period, but equally we could calculate the linear trend from 1999, during the subsequent La Nina, and show a more substantial warming.

 

As we’ve stressed before, choosing a starting or end point on short-term scales can be very misleading. Climate change can only be detected from multi-decadal timescales due to the inherent variability in the climate system. If you use a longer period from HadCRUT4 the trend looks very different. For example, 1979 to 2011 shows 0.16°C/decade (or 0.15°C/decade in the NCDC dataset, 0.16°C/decade in GISS). Looking at successive decades over this period, each decade was warmer than the previous – so the 1990s were warmer than the 1980s, and the 2000s were warmer than both. Eight of the top ten warmest years have occurred in the last decade.

 

Over the last 140 years global surface temperatures have risen by about 0.8ºC. However, within this record there have been several periods lasting a decade or more during which temperatures have risen very slowly or cooled. The current period of reduced warming is not unprecedented and 15 year long periods are not unusual.

 

Temperature and CO2 concentration in the atmosphere over the past 400 000 years.

 

The information presented on this graph indicates a strong correlation between carbon dioxide content in the atmosphere and temperature. A possible scenario: anthropogenic emissions of GHGs could bring the climate to a state where it reverts to the highly unstable climate of the pre-ice age period. Rather than a linear evolution, the climate follows a non-linear path with sudden and dramatic surprises when GHG levels reach an as-yet unknown trigger point.

I have no doubt that at some time in the future our climate will cool down, but for now its warming and the cooling effect of low solar output is unlikely to change that.

 

Noaa doesnt have 200 year old data, i have just looked!!!, please present facts not supposition please

Do you not believe in evolution either, as that uses similar scientific methods. Perhaps you think God is making it warmer?
