This prefab kit makes it easy to retrofit old buildings. The threat of high-probability ocean ‘tipping points’ Climate change is profoundly altering our oceans and marine ecosystems.
Some of these changes are happening quickly and are potentially irreversible. Many are taking place silently and unnoticed. In recent years, tipping points – thresholds where a small change could push a system into a completely new state – have increasingly become a focus for the climate research community. However, these are typically thought of in terms of unlikely changes with huge global ramifications – often referred to as “low probability, high impact” events. How global business could mitigate climate change. Amid the coronavirus pandemic, everyone is rightly focused on protecting lives and livelihoods.
Trillions of extra economic damages predicted in new study of climate change effects. The world is underestimating the economic effects of climate change by trillions of dollars, according to a new study co-authored by scientists from the University of Warwick.
The study, led by Georgetown University and published in Nature Communications today (6 October), shows that current economic forecasting models fail to account for unpredictable variations in global temperatures, rather than the more predictable rising temperatures themselves. Co-author Professor Sandra Chapman, of the University of Warwick Department of Physics, said: "When we cause a system like the Earth's climate to warm, it does not warm smoothly and uniformly. Changes in the Earth's temperature translate into economic damages and our work estimates the additional economic damage that we can expect due to these fluctuations in earth's global mean temperature on top of the smooth gradual increase due to increasing CO2 in the atmosphere. " Cost of Inaction Making New Policies More information: Raphael Calel et al. Net zero by 2050 plan for energy sector is coming. This op-ed article was first published by the Financial Times Our climate challenge is an energy challenge.
The energy that powers our daily lives produces three-quarters of global emissions. Making all of that energy carbon-neutral by 2050 is a Herculean undertaking for our economies and societies that goes well beyond simply setting long-range targets. Top scientists warn of 'ghastly future of mass extinction' and climate disruption. The planet is facing a “ghastly future of mass extinction, declining health and climate-disruption upheavals” that threaten human survival because of ignorance and inaction, according to an international group of scientists, who warn people still haven’t grasped the urgency of the biodiversity and climate crises.
The 17 experts, including Prof Paul Ehrlich from Stanford University, author of The Population Bomb, and scientists from Mexico, Australia and the US, say the planet is in a much worse state than most people – even scientists – understood. “The scale of the threats to the biosphere and all its lifeforms – including humanity – is in fact so great that it is difficult to grasp for even well-informed experts,” they write in a report in Frontiers in Conservation Science which references more than 150 studies detailing the world’s major environmental challenges.
An estimated one million species are at risk of extinction, many within decades, according to a recent UN report. Global heating could stabilize if net zero emissions achieved, scientists say. The world may be barreling towards climate disaster but rapidly eliminating planet-heating emissions means global temperatures could stabilize within just a couple of decades, scientists say.
For many years it was assumed that further global heating would be locked in for generations even if emissions were rapidly cut. Climate models run by scientists on future temperatures were based on a certain carbon dioxide concentration in the atmosphere. If this remained at the current high level there would be runaway climate disaster, with temperatures continuing to rise even if emissions were reduced because of a lag time before greenhouse gases accumulate in the atmosphere. Climate Change Will Roast Cities More Than Anywhere Else.
Heat Islands Scientists are taking aim at a commonly-overlooked problem in the fight against climate change: what to do about cities.
New research shows that the average temperature within a city will rise well beyond the global average temperatures that climate initiatives tend to focus on, Wired reports. In fact, the new models show that metro areas could end up 4.4 degrees Celsius hotter by the year 2100. That presents a major health risk to those that live there, as well as a fresh challenge for those seeking to limit climate change’s impact. Hot Spots For context, the 2015 Paris Agreement seeks to limit global temperatures to a 1.5-degree-Celsius increase over preindustrial levels. New Analysis Shows Climate Could Stabilize in Several Decades. Cold Turkey In an unusual example of optimistic climate change research, scientists now suspect that rising global temperatures and the impacts of climate change could stabilize in a matter of decades.
To be clear, the catch is that the findings would depend on the world rapidly transitioning away from fossil fuels to the point that greenhouse gas emissions reach a net-zero point, The Guardian reports. That’s a staggering challenge, especially because several large countries are already behind on the 2015 Paris Agreement and U.S. President Donald Trump abandoned it altogether. How a 'tree mortgage' scheme could turn an Indian town carbon neutral. In the misty, hilly terrain of Wayanad, in the southern Indian state of Kerala, the people with any access to land in the quiet town of Meenangadi have been out counting their trees.
Sheeja CG, a 46-year-old farmer, has lived among coffee, coconut and pepper plantations all her life but last month she increased her income dramatically by mortgaging 53 of her trees at the local bank, in return for a sum of 2,650 rupees (£26.96), or 50 rupees each. She was one of the first beneficiaries of the state-sponsored scheme. It’s a simple incentive with big gains: plant a tree, and after three years residents can mortgage each sapling for an interest-free loan that can be renewed annually for 10 years. The money need be repaid only if the tree is chopped down. How smallholder farmers can combat their reliance on staple crops - BCFN Foundation: Food and Nutrition Sustainability Index. Dr Morris Akiri, Regional Director Africa, CABI To combat the adverse effects of climate change, smallholder farmers need to adapt and diversify what they grow.
That requires finding better ways to share information and knowledge, says Morris Akiri, regional director for Africa at the Centre for Agriculture and Biosciences International. The world’s population relies overwhelmingly on four staple crops which together account for more than three-quarters of our food supply: maize, rice, soybean and wheat.

Join the conversation using #risks20 The report forecasts a year of increased domestic and international divisions and economic slowdown. Annex. When might the world exceed 1.5C and 2C of global warming? Under the Paris Agreement adopted in 2015, virtually all the world’s nations pledged to limit global warming to “well below” 2C above pre-industrial levels and also, if possible, “pursue” efforts to cap warming at 1.5C. At present, the world is not close to being on track to meet either target. While the growth of global emissions has slowed in recent years, there is a large and growing gap between current commitments and what would be needed to avoid exceeding these global temperature limits.
Reaching UK net zero target cheaper than we thought, says climate adviser. Reaching net zero carbon emissions in the UK is likely to be much easier and cheaper than previously thought, and can be designed in such a way as to quickly improve the lives of millions of people, a senior adviser to the government has said. Chris Stark, the chief executive of the Committee on Climate Change, the UK’s independent statutory adviser, said costs had come down rapidly in recent years, and past estimates that moving to a low-carbon economy would cut trillions from GDP were wrong. “Overall, the cost is surprisingly low – it’s cheaper than even we thought last year when we made our assessments.

A Sensitive Matter Foreword inc. RCP 8.5—A scenario of comparatively high greenhouse gas emissions. IIASA modeling framework RCP8.5 was developed using the IIASA Integrated Assessment Modeling Framework that encompasses detailed representations of the principal GHG-emitting sectors—energy, industry, agriculture, and forestry. The framework combines a careful blend of rich disciplinary models that operate at different spatial resolutions that are interlinked and integrated into an overall assessment framework (Fig. 1). Integration is achieved through a series of hard and soft linkages between the individual components, to ensure internal scenario consistency and plausibility (Riahi et al. 2007). IIASA modeling framework (adapted from Riahi et al. 2007) The three principal models of the IA framework (Fig. 1) are MESSAGE–MACRO (Messner and Strubegger 1995; Rao and Riahi 2006), DIMA (Rokityanskiy et al. 2007) and AEZ–WFS (Fischer et al. 2007) (see below for further details).
