This is the unfinished debate on global warming, is manmade climate change in true evidence and if global warming was to happen would it matter?
Graphs to show other factors affecting global temperature

The global climate change treaty states that we should endeavour to avoid “dangerous interference with the climate system.” But, there is no true definition about what “dangerous interference” actually is.
There is no doubt that average global temperatures have risen 0.5 degrees in the last century however most of this occurred before 1940 when most carbon emissions occurred after that date. We do not even know that excess carbon dioxide causes global warming it could be to do with the correlation between temperature and solar activity or low volcanic or sulphate aerosol activity.
In general, models for prediction of global temperature have not considered these factors yet which may explain how these models cannot account for observed temperatures and may explain these misleading catastrophic predictions of these models in the past. “These models are not even consistent with each other with 300% differences in predictions.”
This global warming scam with trillions of dollars driving it has swept the face of the earth with fear, fear for the future, for the planet and the life on it. There are misleading articles about how sea levels could rise 100 metres when even the IPCC who support climate change say “at worst on best scenarios, 59 centimeters.”
Solar radiation has “increased by 0.2W/m2 since 1750” and the TAR said, "The combined change in radiative forcing of the two major natural factors (solar variation and volcanic aerosols) is estimated to be negative for the past two, and possibly the past four, decades”. A few studies say that the present level of solar activity is historically high as determined by sunspot activity and other factors. Solar activity could affect climate either by variation in the Sun's output or, more speculatively, by an indirect effect on the amount of cloud formation.
From 1940 to 1960 there was a pause in global climatic warming and this is often put down to the increase in sulphate aerosols in the air (global dimming). Christian Ruckstuhl, a renowned climatologist, wrote a paper that found “a 60% reduction in aerosol concentrations over Europe causing solar brightening”
Whether global warming is to continue whether for manmade or natural reasons is still up for debate but if it were to continue, would it really matter? There is much talk about the disastrous conclusions of global warming- increase in malaria, mass flooding and severe storms but among these catastrophes there would also be some benefits.
As Fred Singer, a Research Fellow at the Independent Institute, states in his book Hot Talk, Cold Science Global Warming’s Unfinished Debate, some of these benefits may include “improvement in human well-being. Some benefits include a CO2-enriched biosphere more conducive to plant growth, longer frost-free growing seasons, greater water efficiency for plants, and more available farmland at higher latitudes.”
Contrary to common belief, global warming may reduce the regularity of severe storms as the temperature gradient between the poles and equator would be reduced in size so ocean temperature would move further towards equilibrium. This would cause a reduction in severe storms. Also the the regularity of severe storms has increased in the past 60 years is wrong.
Rising sea levels, another alleged consequence of a global warming, may also be a phantom problem as global warming would most likely lower rather than raise sea levels because more evaporation from the oceans would increase precipitation and thereby thicken the ice caps of Greenland and Antarctica. This possibility has been supported from evidence from observations of the inverse…
