Canada’s ClimateData Web Portal: Normal Science, Not Fake

Skeptical Science - In August, the Canadian government launched a new website called ClimateData.ca which "provides engineers, public health professionals, urban planners, mayors, and anyone else doing long-term planning with user-friendly climate change information, data, resources and tools" (press release). The website uses past weather data from 1950-2011 along with computer modelling to project the possible future impacts of climate change in Canada. Françoys Labonté, the … [Read more...]

More than 500 people misunderstand climate change

RealClimate - A consensus is usually established when one explanation is more convincing than alternative accounts, convincing the majority. This is also true in science. However, science-based knowledge is also our best description of our world because it is built on testing hypotheses that are independently reexamined by colleagues. It is also typical that there are a few stubborn people who think they know better than the rest. When it comes to climate science, there is a small group of … [Read more...]

The consensus on consensus messaging

Skeptical Science - A scientist would never tolerate statements about climate change that weren't based on scientific research and empirical evidence. However, the same evidentiary standards don't always seem to apply to statements about how to communicate about climate change. For example, on the topic of communicating the scientific consensus on human-caused global warming, there are lots of opinions on whether communicating the scientific consensus is effective or not. Many of these opinions … [Read more...]

How much CO2 your country can still emit, in three simple steps

RealClimate - Everyone is talking about emissions budgets – what are they and what do they mean for your country? Our CO2 emissions are causing global heating. If we want to stop global warming at a given temperature level, we can emit only a limited amount of CO2. That’s our emissions budget. I explained it here at RealClimate a couple of years ago: First of all – what the heck is an “emissions budget” for CO2? Behind this concept is the fact that the amount of global warming that is … [Read more...]
