Unplanned Urbanisation Fuels Rising Heat Managing Blue-Green Spaces Key to Mitigation

Unplanned Urbanisation Fuels Rising Heat Managing Blue-Green Spaces Key to Mitigation

Breaking News, Climate Actions, Environment
Urbanisation is coming at the cost of natural blue and green spaces leading to a surge in surface temperatures and exacerbating the Urban Heat Island (UHI) effect. Researchers warn that without sustainable urban planning or urban centres especially in developing nations like India will face hazardous heat stress, threatening both human health and local ecosystems. Urbanisation and Rising Temperatures The C(UN) estimates that by 2050, 68% of the global population will live in urban areas, with 90% of this growth concentrated in Asia and Africa. As a result, the rate of urban land expansion is already twice as fast as population growth, leading to a dramatic transformation of landscapes. Studies project that by the end of the 21st century, the Land Surface Temperature (LST) could ri...
Experts Warn of Rising Urban Heat and Extreme Weather at Anil Agarwal Dialogue 2025

Experts Warn of Rising Urban Heat and Extreme Weather at Anil Agarwal Dialogue 2025

Breaking News, Climate Actions, Thoughts & Talks
At the Anil Agarwal Dialogue 2025, climate experts painted a grim picture of India's worsening extreme weather, highlighting urban heat, rising nighttime temperatures, and the growing impact of climate change on agriculture. Urban Heat and Warm Nights on the Rise In the session titled "In the Red: Why Are Our Cities Heating Up?", experts discussed how increasing urban heat islands and warm nights are endangering public health and livelihoods. Climate scientist Roxy Mathew Koll from the Indian Institute of Tropical Meteorology, Pune, explained that India is highly vulnerable to extreme weather due to its tropical location and rapidly warming oceans. “The Indian Ocean may enter a permanent heatwave state by 2050,” Koll warned, adding that oceanic heatwaves could increase from 20–50 ...
Karnataka to Stay Hot Humid as Pre-Monsoon Showers Expected in March

Karnataka to Stay Hot Humid as Pre-Monsoon Showers Expected in March

Breaking News, Climate Actions, Environment
Karnataka will continue to experience hot and humid conditions, with scattered rainfall likely in some parts over the next two weeks, according to the India Meteorological Department (IMD). Maximum temperatures are expected to remain 3-5°C above normal across the north peninsular region, including Karnataka. Temperature data from the Karnataka State Natural Disaster Monitoring Centre (KSNDMC) showed that most districts recorded highs above 35°C in mid-February, with northern regions like Kalaburagi, Vijayapura, and Yadgir reaching around 37.5°C. Bengaluru Urban saw a maximum temperature of 34.8°C. While a slight drop in temperatures is forecast for the last week of February, IMD predicts that pre-monsoon showers will likely arrive after the first week of March. The state has so far r...
Australians Face Death Risk in Heatwaves: Study Reveals Cities as Hotspots for Extreme Temperature & HVI

Australians Face Death Risk in Heatwaves: Study Reveals Cities as Hotspots for Extreme Temperature & HVI

Breaking News, Climate Actions, Disasters
A groundbreaking study conducted by researchers from the University of Queensland and Griffith University has revealed that urban residents in Australia face a significantly higher risk of death during heatwaves compared to their rural counterparts. The research, published in the Environmental Impact Assessment Review in March 2025, examined two decades of temperature and mortality data across Australia’s major cities, including Melbourne, Sydney, Adelaide, Brisbane, Hobart, Perth, and Darwin. The study utilized the Heatwave Vulnerability Index (HVI) to identify regions most susceptible to heatwave-related fatalities. Even during mild heatwaves, there was a notable correlation between deaths and HVI scores in Australia’s capital cities. The far north and southern regions of Western Aust...
Global Temperature Crosses 1.5°C Threshold in 2024, Marking New Climate Era

Global Temperature Crosses 1.5°C Threshold in 2024, Marking New Climate Era

Breaking News, Climate Actions, Fact Check
The average global temperature anomaly in 2024 surpassed the critical 1.5°C threshold for the first time, signaling a significant milestone in the planet’s ongoing warming trend. This development, highlighted by the World Meteorological Organization (WMO), marks a clear step into a phase of sustained global warming. The 1.5°C limit, a target established under the 2015 Paris Agreement, aimed to prevent the worst impacts of climate change by keeping global temperature rise below this level compared to pre-industrial times (1850-1900). However, the WMO confirmed that the annual average global temperature in 2024 was 1.55°C above pre-industrial levels, based on six independent datasets. The European Commission’s Copernicus Climate Change Service (C3S) added that 18 of the last 19 months ...
World Sets Record January Heat Despite La Nina Scientists Debate Accelerating Global Warming

World Sets Record January Heat Despite La Nina Scientists Debate Accelerating Global Warming

Breaking News, Climate Actions
The world warmed to a new monthly heat record this January, despite cooling factors like a La Nina event and an abnormally chilly United States, according to the European climate service Copernicus. This surprising temperature rise is sparking debate among scientists, with some arguing that global warming is accelerating. Copernicus reported that January 2025 was 0.09 degrees Celsius warmer than January 2024, the previous hottest January on record. It was also 1.75 degrees Celsius warmer than pre-industrial levels. This marks the 18th month out of the last 19 in which the world hit or surpassed the 1.5-degree warming threshold set by the Paris Agreement. However, scientists only consider the threshold breached when temperatures stay above it for 20 consecutive years. Copernicus has t...
2025 record heat highlights January become the hottest month Ever in the history

2025 record heat highlights January become the hottest month Ever in the history

Breaking News, Climate Actions, Disasters, Environment
January 2025 was the hottest on record - a whole 1.7°C above pre-industrial levels. If many climate-watchers expected the world to cool slightly this year thanks to the natural "La Niña" phenomena, the climate itself didn't seem to get the memo. In fact, January 2025's record heat highlights how human-driven ocean warming is increasingly overwhelming these natural climate patterns. La Niña is a part of the El Niño southern oscillation, a climate fluctuation that slowly sloshes vast bodies of water and heat between different ocean basins and disrupts weather patterns around the world. El Niño was first identified and christened by Peruvian fishermen who noticed a dismal drop in their catch of sardines that coincided with much warmer than usual coastal waters. El Niño is now well known...

Sierra Leone’s capital, Freetown, has taken a groundbreaking step in climate adaptation by launching Africa’s first Heat Action Plan (HAP) to tackle the growing threat of extreme heat. The initiative was unveiled during the first-ever African Urban Heat Summit on February 6, 2025, organized by Freetown’s city government and Climate Resilience for All (CRA), a global climate adaptation NGO. The summit brought together African mayors, policymakers, and climate experts to discuss urban heat resilience. Sierra Leone’s Vice President Mohamed Juldeh Jalloh and Freetown Mayor Yvonne Aki-Sawyerr introduced the HAP, emphasizing its importance in protecting vulnerable communities from rising temperatures. “Extreme heat is disrupting lives, straining healthcare systems, and threatening economic st...
Record January Heat Shows La Niña Struggling to Cool a Warming World

Record January Heat Shows La Niña Struggling to Cool a Warming World

Breaking News, Climate Actions, Environment
January 2025 has shattered temperature records, marking the hottest start to a year ever recorded 1.7°C above pre-industrial levels. Many climate watchers expected a cooling effect due to the natural La Niña phenomenon, but global warming appears to be overpowering it. Scientists now warn that human-driven ocean warming is beginning to overwhelm natural climate patterns, making temporary cooling phases like La Niña less effective. La Niña is part of the El Niño Southern Oscillation (ENSO), a climate pattern that influences global temperatures by shifting ocean heat between basins. While El Niño causes warming, La Niña typically brings cooler global temperatures by shifting heat away from the eastern Pacific. Historically, La Niña has helped suppress temperature spikes, but this year, ev...
