India and climate change: implications of setting a net zero target

The 1.5C report of the Intergovernmental Panel on Climate Change (IPCC) highlights the importance of achieving a net future with zero greenhouse gases. Many countries have announced their commitment to achieve a net zero future for their economies. India, while doing far more than its “fair share” of mitigation, has yet to announce a net […]

How Scientists Predict Climate Scenarios – Enter the World of Climate Models

The climate of our planet is an extremely complex subject. Of course, the underlying principles are simple, but incorporating the interaction between all the different elements is a very difficult task. To assess the situation on a large scale, researchers often turn to what are called climate models. A climate model is a quantitative simulation […]

Even 50 years ago, climate models were far more accurate than deniers claim

It’s a common refrain from those who question the findings of climate science: the computer models scientists use to project future global warming are inaccurate and shouldn’t be trusted to help policymakers decide whether to they must take potentially costly measures to limit greenhouse gas emissions. A new study effectively quells this argument by examining […]
