Climate change is impacting population health

Last week, medical and healthcare students across the world stood in solidarity with the global youth climate strike. We are increasingly concerned about the harmful impact of the climate crisis on the health of our patients and the population. Therefore, as both students and future healthcare professionals, we made the decision to join the youth

While global leaders messed around, Greta Thunberg and 15 kids got down to business

The United Nations’ secretary-general António Guterres wanted international leaders to bring plans, not speeches to the Climate Action Summit being held in New York today. Greta Thunberg and 15 other young people don’t seem to have much faith in these plans. On Monday, hours after Thunberg addressed assembled leaders at the summit’s opening ceremony, the group of

Harvard joins Climate Action 100+

Harvard University announced today that its endowment has joined Climate Action 100+, an investor-led initiative to ensure that the world’s largest corporate greenhouse gas emitters take steps to address climate change. As a member of this global network, representing more than $34 trillion in combined assets, Harvard Management Company (HMC) will join other investors in

The most effective ways to curb climate change might surprise you

The planet is barreling toward 1.5 degrees of global warming as soon as 2030 unless we enact “unprecedented changes in all aspects of society,” a dire United Nations report warned in October. To reduce our impact on the climate and avert disaster, it’s going to take more than switching to high-efficiency light bulbs. But the most effective

Climate change to shrink economies

Prevailing economic research anticipates the burden of climate change falling on hot or poor nations. Some predict that cooler or wealthier economies will be unaffected or even see benefits from higher temperatures. However, a new study co-authored by researchers from the University of Cambridge suggests that virtually all countries -- whether rich or poor, hot

Climate Change Threatens the World’s Food Supply, United Nations Warns

The world’s land and water resources are being exploited at “unprecedented rates,” a new United Nations report warns, which combined with climate change is putting dire pressure on the ability of humanity to feed itself. The report, prepared by more than 100 experts from 52 countries and released in summary form in Geneva on Thursday, found that the window

Fastest climate warming than in the last 2,000 years’

Many people have a clear picture of the "Little Ice Age" (from approx. 1300 to 1850). It's characterized by paintings showing people skating on Dutch canals and glaciers advancing far into the alpine valleys. That it was extraordinarily cool in Europe for several centuries is proven by a large number of temperature reconstructions using tree

Could climate change make Siberia more habitable?

Large parts of Asian Russia could become habitable by the late 21st century due to climate change, new research has found. A study team from the Krasnoyarsk Federal Research Center, Russia, and the National Institute of Aerospace, USA, used current and predicted climate scenarios to examine the climate comfort of Asian Russia and work out

Changes in rainfall have already impacted water quality

Changes in temperature and precipitation have already impacted the amount of nitrogen introduced into U.S. waterways, according to new research from a team of three Carnegie ecologists published this week in Environmental Science & Technology. Nitrogen from agriculture and other human activities washes into waterways, which, in excess, creates a dangerous phenomenon called eutrophication. This

Global warming disrupts recovery of coral reefs

The damage caused to the Great Barrier Reef by global warming has compromised the capacity of its corals to recover, according to new research published today in Nature. "Dead corals don't make babies," said lead author Professor Terry Hughes, Director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University (JCU).

Humanitarian crises and climate change—

Burundi, Chad and Sudan are home to some of the world’s largest displaced populations and vulnerable communities. Burundi’s Gitega Province, which has one of the country’s highest population densities, hosts several thousands of people in refugee settlements and camps. About 96 per cent of families use fuelwood as a primary energy source for cooking. In

Rainfall changes for key crops predicted

Even if humans radically reduce greenhouse gas emissions soon, important crop-growing regions of the world can expect changes to rainfall patterns by 2040. In fact, some regions are already experiencing new climatic regimes compared with just a generation ago. The study, published March 11 in Proceedings of the National Academy of Sciences, warns that up

Research connects dots among ocean dynamics, drought and forests

In a time of drastic change, humans look for predictability. A recent study led by a University of Wyoming researcher found that even in dramatically changing climates, mechanisms can be found that predict how those changes will play out. The last ice age was 11,000 years ago and, since then, climates have continuously changed, triggering

Climate change is shifting productivity of fisheries worldwide

Fish provide a vital source of protein for over half the world's population, with over 56 million people employed by or subsisting on fisheries. But climate change is beginning to disrupt the complex, interconnected systems that underpin this major source of food. A team of scientists led by Christopher Free, a postdoctoral scholar at UC

Natural and industrial approaches to global decarbonization

In the fight to slow climate change, nature is a powerful weapon. In fact, natural climate solutions, such as reducing deforestation and changing farming practices, can soak up excess carbon in the atmosphere and prevent certain emissions so effectively that it might be tempting to think they can buy us time while we figure out

Climate change makes summer weather stormier yet more stagnant

Climate change is shifting the energy in the atmosphere that fuels summertime weather, which may lead to stronger thunderstorms and more stagnant conditions for midlatitude regions of the Northern Hemisphere, including North America, Europe, and Asia, a new MIT study finds. Scientists report that rising global temperatures, particularly in the Arctic, are redistributing the energy

How small farmers could be leading the way towards sustainable agriculture

Agriculture is a leading cause of climate change, but it is also undeniably affected by it. Farming must therefore change in order to keep up with global demands, while reducing its environmental impact. Without these necessary changes, it’s estimated that by 2030, the impacts of climate change will be even worse, causing yields to decline

Asia faces contradictions with climate change

On Saturday climate change delegates concluded their latest round of negotiations on implementing the Paris agreement at the UN climate conference in Katowice, Poland. The delegates at COP24 worked to agree on a so-called "rule book" for the Paris agreement that spells out a cohesive set of standards and procedures for enacting emissions-reducing policies to be followed
