9 Greenhouse gas concentrations over past 1000 years Carbon dioxide concentrations have increased by 44% since the industrial revolution and are now at their highest level in 2 million years.
10 Empirical evidence that humans have caused climate change 1. Carbon dioxide is a greenhouse gas. The natural greenhouse effect makes the planet habitable: the earth is 33 C warmer than it would be in the absence of greenhouse gases. Laws of physics and direct measurements confirm that carbon dioxide absorbs heat, i.e. acts as a greenhouse gas.
11 Evidence that humans have caused climate change 2. Carbon dioxide concentrations in the atmosphere have increased since the industrial revolution.
12 Evidence that humans have caused climate change 3. The extra carbon dioxide in the atmosphere has come from burning of fossil fuels. State of the Climate 2016 (CSIRO and Bureau of Meteorology)
13 Evidence that humans have caused climate change 3. The extra carbon dioxide in the atmosphere comes from burning of fossil fuels. Oxygen concentrations in the atmosphere have declined, at the rate expected from burning carbon rich fuels. CO 2 in the atmosphere has increased as human emissions have increased (the two are correlated). In recent decades, nature has absorbed more CO 2 than it has emitted, so natural sources cannot explain the observed increase in the atmosphere. Oxygen Carbon dioxide
14 Evidence that humans have caused climate change 4. The additional carbon dioxide added to the atmosphere by human activities has enhanced the greenhouse effect. Less energy is leaving the top of the atmosphere in the wavelengths absorbed by carbon dioxide and other greenhouse gases. Harries et al., Nature (2001)
15 Evidence that humans have caused climate change 4. The additional carbon dioxide added to the atmosphere by human activities has enhanced the greenhouse effect. Models can reproduce measured warming if effects of increased greenhouse gas forcing are included, but cannot do so with natural forcings alone. Source: IPCC 5 th Assessment Report, Working Group I Summary for Policy Makers
16 Evidence that humans have caused climate change 5. The earth has warmed as a result of the enhanced greenhouse effect. Surface temperature ( C) Lower atmosphere ocean heat content
17 Evidence that humans have caused climate change 6. Observed changes in the climate system are consistent with an enhanced greenhouse effect. Other forcings (e.g. volcanoes, the sun) and internal variability cannot explain the magnitude, timing and distribution of observed trends. For example, enhanced greenhouse forcing warms the lower atmosphere and cools the upper atmosphere, as observed. Increases in solar energy would warm both the upper and lower atmosphere.

The extra carbon dioxide comes from human activities. 4.

40 COP21: the Paris Agreement The first truly global climate agreement. Agreement to limit global warming to less than 2 C (and preferably to less than 1.5 C). Can we do it?
41 Antarctic commitment to future sea level rise Golledge et al., Nature, 2015
42 Carbon budget Warming Cumulative carbon dioxide emissions
43 Carbon clock
44 Summary Warming is unequivocal human influence is clear. Ocean uptake of heat and carbon dioxide slows climate change but at the cost of sea level rise and ocean acidification. The Southern Ocean is a powerful player in the climate system. Time is running out if we want to minimise the risk of crossing critical thresholds, such as an irreversible commitment to sea level rise from loss of ice sheets. Esmee van Wijk
