As the world works to keep temperature increase from climate change below 2 degrees Celsius , a smaller increase than that has already led to deadly heat in India . A new study reveals an average temperature increase of just 0.5 degrees Celsius means the country is two and a half times more likely to be hit with a deadly heat wave than it was 50 years ago. Between 1960 and 2009, average temperatures in India increased by 0.5 degrees Celsius, which is under one degree Fahrenheit. The probability of a large heat-related mortality event – where more than 100 people perish – skyrocketed by 146 percent, according to the new study. Researchers also found the amount of heat wave days increased by 25 percent in much of the country. Between 1985 and 2009 part of south and west India saw 50 percent more heat wave events, or extreme heat that lingers for more than three or four days, compared to the 25 years prior.

We knew there was going to be an impact, but we didn’t expect it to be this big.” This is bad news for a region already grappling with heat. Neighboring Pakistan experienced the hottest ever temperature recorded in May in the world with a temperature of 53.5 degrees Celsius, or 128.3 degrees Fahrenheit, in the city of Turbat on May 28. And in New Delhi , temperatures have spiked higher than 44 degrees Celsius, or 111 degrees Fahrenheit, in the last couple of weeks. Study co-author Amir AghaKouchak, another UC Irvine climatologist, said, “The general public may think that a one or two degree temperature rise is not that significant, but our results show that even small changes can result in more heat waves and more death.” The journal Science published the study this week.

Climate change could make cities 8C hotter by 2100, new studies show

Comments Off on Climate change could make cities 8C hotter by 2100, new studies show

Climate change is raising temperatures , but the impact could be worse in the world’s cities . Researchers say the urban heat island effect – or the fact that cities are hotter thanks to human activity – combined with climate change could increase temperatures in urban areas by around 14.4 degrees Fahrenheit, or eight degrees Celsius, by the end of the 21st century. Three researchers led by Francisco Estrada of the Universidad Nacional Autónoma de México and the Institute of Environmental Studies projected city temperatures could rise by around five degrees Celsius due to climate change, as well as an additional two or three degrees Celsius as asphalt and concrete crowd out parks and lakes in metropolises, inducing the urban heat island effect. Such increased temperatures could impact human health and burden natural resources . Related: New NOAA tool shows how climate change will affect your neighborhood As major cities prepare for the impacts of climate change, many of them likely haven’t been considering the urban heat island effect. The researchers said many impact estimates don’t include the effect. So they drew on average planetary warming projections combined with the effect, and used data from 1,692 of Earth’s biggest cities between 1950 and 2015, to determine the economic costs of climate change. They also built their research on worse case scenarios: if carbon emissions continue to rise instead of declining. The results aren’t pretty: cities hit the hardest could lose 10.9 percent of GDP by 2100. Only around one percent of the planet’s surface is covered with cities, but the urban centers produce around 80 percent of gross world product. Around 78 percent of the energy consumed worldwide happens in cities. They also generate over 60 percent of global carbon emissions from burning fossil fuels . Cities have a chance to act on the research now – mitigating the urban heat island effect by taking actions like planting trees ; green roofs could help too. The journal Nature Climate Change published the research online this week. Via The Guardian Images via Pixabay and Wikimedia Commons

Comments Off on Australian Government Links Recent Extreme Weather to Global Warming for the First Time

Australia has had one heck of a summer this year, from flooding to fires and multiple record high temperatures . But until now, the link between these events and climate change has largely been ignored by the nation’s government and media. That changed this week when Australia’s independent Climate Commission released their “ Angry Summer ” report, which details just how climate change is impacting the nation’s escalating extreme weather.
