Fact check: has global warming paused?

argylesock says… Climate science can be quite difficult to understand – difficult to me, anyway – and people get angry about it. I’m reblogging this particular post because it makes sense.

By Andrew Glikson, Australian National University

“The UN’s climate change chief, Rajendra Pachauri, has acknowledged a 17-year pause in global temperature rises, confirmed recently by Britain’s Met Office, but said it would need to last ‘30 to 40 years at least’ to break the long-term global warming trend.” – The Australian, Feb 22 2013

Since the onset of the industrial age (from 1750 AD) Earth’s atmosphere, surface and ocean temperatures have warmed. This is mainly due to the rise in greenhouse gases (CO2, CH4, N2O, O3, halocarbons, stratospheric water vapour from CH4) by a total of +3.06 Watt/m2. Other drivers include black carbon (+0.1 Watt/m2) and solar irradiance – the latter during the first half of the 20th century (+0.12 Watt/m2).

Warming was in part mitigated by emitted sulphur aerosols (direct effects…

About argylesock

I wrote a PhD about veterinary parasitology so that's the starting point for this blog. But I'm now branching out into other areas of biology and into popular science writing. I'll write here about science that happens in landscapes, particularly farmland, and about science involving interspecific interactions. Datasets and statistics get my attention. Exactly where this blog will lead? That's a journey that I'm on and I hope you'll come with me.

    To summarise, claims that warming has paused over the last 16 years (1997-2012) take no account of ocean heating.
