How to distinguish myths from realities, science from mere assumptions, conspiracy theories and propaganda? Serious research has an important tool: peer-reviewed articles published in scientific journals. (Be aware that there are fake journals on the internet. Check name, spelling and URL carefully!) This involves an editorial committee and at least two experts in the field considering the quality. They propose necessary improvements before publication. It is a laborious process. Most scientists have one or more times become annoyed to learn that the article did not add new knowledge or that source material was incomplete. Most universities have lists of officially approved scientific journals that their researchers can check before publishing.
Researchers who do not publish peer-reviewed articles, lose status. Some of those who do not get published in scientific journals tend to believe that such articles are unreliable and overvalued.
Climate deniers have difficulties publishing in scientific journals because they use sources like the Heartland- or Cato institutes. These sources are financed by the world’s largest oil producers and fossil fuel companies, carbon barons like David and Charles Koch and the American big tobacco industry. These institutes claim that we have been in a “warming pause” or hiatus since 1998. This is an example of “cherrypicking”. The author picks out the information that fits, while ignoring the rest. Cherrypicking guarantees that you will not be able to publish your article in a scientific journal.
The picture shows why 1998 is “cherrypicking”: it is an extreme year, the warmest year during the last century, with unusual solar activity and the strongest El Nino in a hundred years. Choose 1992 or 1985 instead, and you see that the warming has been dramatic.
Serious climate research does not use a single year as a starting point, but average temperatures over years. The meteorological Normal is the average weather in a place for 30 years and is an expression of climate. Weather is what happens in the moment or over a year or two. Using 1998 as a basis reference year when discussing climate change is mixing of weather and climate and is simply deceptive.
Deniers claim that the IPCC cannot explain the “warming pause”. The reality is different. When warming of the atmosphere has not accelerated as much as expected with increasing concentrations of greenhouse gases, this has to do with the fact that global warming is simply not linear, low solar activity and dramatic increases of particles in the air from the burning of coal and oil, especially in Asia. In addition comes the cooling effect of many smaller volcanic eruptions. An active “Pacific Decadal Oscillation“, which is now coming to an end, has transported much of the extra heat into the deep sea.
When deep sea warming is included and average temperatures are used in the calculations, there is no “warming pause” according to a report by the World Meteorological Organization in 2013. This is confirmed by Science 2015: “Data show no recent slowdown in global warming“.

Deniers like to provide the public with imaginative claims about the IPCC research. In reality the IPCC does not do research of its own and has never done it. The IPCC reports on the research published in peer-reviewed scientific journals over five-year periods. The recent IPCC reports are based on 30 000 such articles, in turn based on empirical research. The reports are not dependent on models, as deniers like to claim. Models are based on the best available knowledge, are only a small part of the work, and give an idea of what might happen under various assumptions.
The IPCC says that only CO2 affects the climate, it is claimed. Those who take the trouble to read the reports will quickly find out that the IPCC operates with a plethora of factors as “driving forces” and that CO2 previously often had a reinforcing “feedback”-effect after other factors have started up a climate change. The IPCC has never said that CO2 always is the initiating temperature driver.
According to NASA, global average temperatures have developed as expected. However, we should expect a jump in the near future.
The “jump” in global temperature seems to take place in 2015-2016.
NASA has comprehensive long-term datasets on temperatures at GISS Surface Temperature Analysis (GISTEMP). NOAA National Climatic Data Center has similar datasets. The UK Met Office Hadley Centre also has long term temperature data sets. All instances conclude that the global average temperature undoubtedly has increased the last decades.

A common claim from the fossil fuel propaganda industry is that the relationship between more CO2 and global warming has not been proven. A few decades ago the tobacco industry similarly claimed that cigarettes were good for you and that any connection between cigarette smoking and cancer was not proven. History repeats itself. In reality, several climate scientists have demonstrated how CO2 drives temperature. The most recent article appeared In this year’s March issue of Nature: Feldman and colleagues (2015) observational determination of surface radiative forcing by CO2 from 2000 through 2010.
Natural forcing alone can not explain the graphic below. Natural forcing, cooling aerosols, ocean currents and increases in greenhouse gases must all be included. The data are all direct measurements and not related to models.
One can always continue to discuss the “Pope’s beard” in perpetuity. But the elephant is still in the room: Daily we burn over 90 million barrels of oil and an equivalent amount of coal and gas. Annually we burden nature with between 30 and 40 billion tonnes of extra CO2 from fossil sources. The air pollution is fatal in many places. Our seas turn acidic. The climate in large parts of the world is changing, the ice edge in the Arctic is increasingly moving further north and Greenland and West Antarctica ice caps are melting. The capital accumulation with bloodthirsty petro-tyrants in the Middle East is huge, while oil-based economies are becoming increasingly vulnerable. Our ecological debt increases. New, renewable forms of energy are available, but under attack by international fossil industry.
It’s time to shelve the “skeptics” conspiracy theories, escapism and myths. We must begin the work for sustainable development and secure the future for our children. We’re late.
