\u201cClimate science is not normal science,\u201d Danish astrophysicist Dr Henrik Svensmark says. \u201cIt\u2019s a bad career move to go against the idea that CO2<\/sub> is the only driver of climate change,\u201d he notes. In other words, to say that important causes of climate change might lie elsewhere means losing your research funding. For many scientists, this would mean the end of their scientific career, as without funding, it is impossible to conduct research. \u201cThere\u2019s so much politics involved in it even in academia. There is a sort of self-censorship.\u201d.<\/p>\n

Pressure from climate activist circles against scientists who dare to approach the issue scientifically can sometimes even get physical. Svensmark recalls a conference in Germany at which he gave a presentation that required police protection, since demonstrators wanted to storm into the conference hall.<\/p>\n

On another occasion, glue was poured into the door locks of the conference building to prevent participants from entering, and graffiti was sprayed on the building, saying it was a Nazi gathering. \u201cThere\u2019s nothing rational about such actions, and it is difficult to have a meaningful discussion. You also hear people saying that the science has been done. Now it\u2019s only climate action that is needed,\u201d Svensmark says, noting that such statements are nothing but propaganda.<\/p>\n

Sun instead of CO2<\/sub><\/strong><\/p>\n

Professor Svensmark has spent his long scientific career studying the effects of the Sun and cosmic radiation on the Earth\u2019s climate. He is a former head of the Sun-Climate Research Centre at the Danish National Space Centre. He currently holds a senior researcher position at the Technical University of Denmark\u2019s Department of Space Research and Technology.<\/p>\n

Svensmark says that CO2<\/sub> is a greenhouse gas, and there is no doubt about it affecting the temperature. However, he says that this effect is relatively benign \u2013 probably about one degree for every doubling of CO2<\/sub> in the atmosphere.<\/p>\n

One degree is not a very big change, considering that we know from the Earth\u2019s long history that there have been truly dramatic climate fluctuations. There have been periods when ice covered the planet all the way to the equator, and there have been periods when there was practically no continental ice and the air temperature was perhaps even 10 degrees higher than today. \u201cIf we look at geological timescales, we have had enormous changes in climate. And of course, all of this is completely natural. And the question is, why did we have such big climate changes? My work can explain why we have such large climate changes,\u201d Svensmark says. The idea is that energetic particles born in the aftermath of exploding stars, called cosmic rays, can affect Earth\u2019s cloud cover. Regulating clouds will impact Earth\u2019s energy balance and, thereby, climate.<\/p>\n","protected":false},"excerpt":{"rendered":"
