But, regardless of the influence of vested interests and deniers, it is difficult for politicians to act on climate change when the public believes other issues are more important.Understanding the relationship between public opinion and climate policy can help focus the efforts of climate campaigners.

I conducted an online survey in the UK and found 78 percent of respondents were extremely or fairly certain climate change is happening.
But when asked to rank eight issues (climate change, healthcare, education, crime, immigration, economy, terrorism and poverty) from most to least important to the country, 38 percent ranked climate change as least important, with a further 15 percent placing it seventh out of eight.
Recent pledges from a number of large countries to reach net-zero in greenhouse gas emissions by 2050 have led Climate Action Tracker to project that limiting warming to 2 degrees celsius by 2100 may be possible.
Although this progress is heartening, it has taken many years to reach this point and the challenges in actually meeting these emission targets cannot be overstated.
Climate ranking in other countries I found similar results in other countries. Based on a Eurobarometer survey of 27,901 European Union citizens, a majority of the populations in all EU member countries are concerned about climate change, but only 43 percent across the EU rank it in the top four most important issues for the world. There are some differences between countries — climate change tends to be ranked higher in Nordic countries and lower in Eastern Europe.

If people are not thinking about an issue when they go to vote, politicians are less likely to give that issue much attention. As my research shows, people in most countries don’t give climate change a high importance ranking, and politicians are therefore not under enough public pressure to take the difficult steps required to combat climate change.
There are other reasons for the slow political response to climate change, besides the low importance of climate change among the public. Vested interests, such as fossil fuel companies, are undoubtedly involved in slowing the adoption of strong climate policies in many countries.
