Kerry Emanuel writes: There are strong cultural biases against discussion of ‘tail risk’ in climate science; particularly the accusation of “alarmism”. Does the dictum to tell “the truth, the whole truth, and nothing but the truth” not apply to climate scientists? If we omit discussion of tail risk, are we really telling the whole truth?

‘As the waters rise,’ Jeff Goodell writes, ‘millions of people will be displaced, many of them in poor countries, creating generations of climate refugees that will make today’s Syrian war refugee crisis look like a high school drama production.’ There’s no longer any doubt that the rise in global sea levels will reshape human civilisation.
Around 127 people died and 300 others injured during the severe dust and thunderstorms that shook north India on May 2; wind speeds of 126 kilometres making it the strongest storm in six years. The world may see more such freak storms due to rising temperatures; reducing pollution and protecting forests are perfect preventive measures.
Limiting global warming to 1.5C requires strictly limiting the total amount of carbon emissions between now and the end of the century. However, there is more than one way to calculate this allowable amount of additional emissions, known as the “carbon budget”. In this article, Carbon Brief assesses nine new carbon budget estimates released recently.
From Down to Earth: According to an IIT Gandhinagar study, population exposure to heat waves is expected to increase by a massive 200-fold increase if carbon emissions continue under a business-as-usual scenario. Heat wave is already the third biggest natural killer in the country, but is not recognised as a natural calamity by the government.
This latest news immediately brings some questions to mind: Does this mean that we should stop working toward mitigating climate change? Should we stop worrying and enjoy mindlessly by indulging ourselves in senseless consumerism? I really don’t know. But what I definitely know is that the window of opportunity to act is closing really fast.
When a group of us visited Boatkhali Kadambini Primary School four years ago, classes were on in full swing. This primary school is at one edge of Sagar island in the Sunderbans. That entire stretch, including the Boatkhali school, has now been swallowed up by the sea, including the house in which we had stayed.
Nidhi Jamwal writes: The India Meteorological Department claims its job was done by forecasting the cyclone, whereas the affected state government believes its rescue and relief actions are “a formidable achievement”. However, the deadly (mis)management of Ockhi raises some important questions, for which clear action-points are needed to avoid a similar situation in the future.
“This may take a while, but we’re going to win.” This is true about most political fights, but not for climate change. If we don’t win very quickly on climate change, then we will never win. That’s the core truth. It’s what makes climate change different from every other problem our political systems have faced.
From Grist.org: Two Antarctic glaciers act as a plug holding back enough ice to pour 11 feet of sea-level rise into the world’s oceans —an amount that would submerge every coastal city on the planet. Finding out how fast these glaciers will collapse is one of the most important scientific questions in the world today.
From The Guardian: Of all the most polluting nations –United States, China, Russia, Japan and the EU bloc– only India’s carbon emissions are rising: they rose almost 5% in 2016. India’s population and emissions are rising fast, and its ability to tackle poverty without massive fossil fuel use will decide the fate of the planet.
Moin Qazi writes: The Indian film celebrity Aamir Khan is shepherding a very revolutionary campaign–making Maharashtra drought-free in five years. Khan’s Paani Foundation is galvanising the rural population to go back to fundamental lessons of water management taught by their ancestors. Many Maharashtra villages are seeing water in their parched lands after consecutive dry years.
From Yale Environment 360: The wildfires presently raging in California are no exception. The increase in forest fires, seen from North America to Brazil, from the Mediterranean to Siberia, is directly linked to climate change, scientists say. And as the world continues to warm, there will be greater risk for fires on nearly every continent.
Hurricane Maria, which has devastated Puerto Rico, has left 97% the island’s population without power. Electricity is the essential pillar upon which the operations of all modern industrial societies depend. When electricity stops, pretty much everything else stops, as Puerto Rico demonstrates. Given an increasingly unstable climate, it’s a warning for everyone, writes Kurt Cobb.
Peter Brannen writes: Climate change is pushing more water into the atmosphere—with bizarre consequences. We’re headed toward a more arid world but one with unprecedented bursts of floodwaters. And in the tropics, a coming deluge unlike any witnessed by humanity. Also, James Hansen, Naomi Klein and others on climate change and hurricanes Harvey and Irma.
From The Wire: The recent hurricanes have made some raise an obvious question: to what extent does global warming have a role to play? To which I would add one voiced less frequently: why should those least responsible for global warming have to constantly face its effects? And what does it bode for the future?
From Down to Earth: India’s vicious cycle of crippling drought and then devastating floods, which happens every year, is getting a new normal. First, floods and droughts come together. Secondly, rainfall is not only variable but also extreme. There’s only one answer: obsessive attention to building millions and millions of connected and living water structures.
From Jacobin Magazine: Increasingly, extreme weather events including the annual floods are being recognized as the new normal. Less commonly noted is how this “new normal” tends to disproportionately hit the underclasses—the urban poor, agriculturalists, coastal communities, and poor women. In short, the greatest victims of global warming will be those least responsible for it.
From The Third Pole: For the third year in a row, India’s monsoon season has produced floods in the northwest/northeast, while south India has a rainfall deficit. The key question right now is whether we’re headed towards increased monsoon extremes, or whether global warming is causing shifts in the duration, intensity and frequency of rainfall.
From Grist.org: Yes, we should be having the conversation about climate change and the unprecedented floods, and anyone who tells you otherwise probably has ulterior motives. But before we go there, we need to show the victims that we genuinely care about them. Could our shared value be the lives of those who are hurting?
