With unchecked emissions of climate pollutants, there is a 50% probability for the planetary warming to cross the so-called dangerous threshold of 2C by 2050; and there is at least a 5% probability the warming can exceed a catastrophic 6C in about 80+ years. Veerabhadran Ramanathan speaks about climate change in March 2017, at a…

Using satellite and field work after an extreme melt event in Greenland, a UCLA-led study finds that melt-prone areas on its ice sheet develop a remarkably efficient drainage system of stunning blue streams and rivers that carry meltwater into moulins (sinkholes) and ultimately the ocean. However, the team’s measurements at the ice’s edge show that…
