Picture of the Day

[edit]
Contemporary climate change involves rising global temperatures and significant shifts in Earth's weather patterns. Climate change is driven by emissions of heat-trapping greenhouse gases such as carbon dioxide and methane. Emissions come mostly from burning fossil fuels (coal, oil and natural gas), and also from agriculture, forest loss, cement production and steel making. Climate change causes sea level rise, glacial retreat and desertification, and intensifies heat waves, wildfires and tropical cyclones. These effects of climate change endanger food security, freshwater access and global health. Climate change can be limited by using low-carbon energy sources such as wind and solar energy, by forestation, and shifts in agriculture. Adaptations such as coastline protection cannot by themselves avert the risk of severe, pervasive and irreversible impacts. Limiting global warming in line with the goals of the 2015 Paris Agreement requires reaching net-zero emissions by 2050. This animation, produced by NASA's Scientific Visualization Studio with data from the Goddard Institute for Space Studies, shows global surface temperature anomalies from 1880 to 2023 on a world map, illustrating the rise in global temperatures. Normal temperatures (calculated over the 30-year baseline period 1951–1980) are shown in white, higher-than-normal temperatures in red, and lower-than-normal temperatures in blue. The data are averaged over a running 24-month window.Video credit: NASA; visualized by Mark SubbaRao



Tip of the Day

Giving editor awards

Whether an editor collaborates with a team of editors on a WikiProject or is improving articles independently, an editor can give a Wikipedia award (often a barnstar) to another deserving editor.

Editors may reward vigorous Wikipedia contributors for their hard work and due diligence by awarding them a fitting barnstar, or other award. In addition to these virtual awards, editors may nominate someone to receive a gift in the mail from the Wikimedia Foundation.

A list of barnstar awards is available at Barnstar award templates.

Flower of Hong Kong - Bauhinia Blakeana 

The current HKCOTW is Yuen Woo-ping .

Please help improve it to featured article standard.
Every week, a Hong Kong-related topic, stub or nonexistent article is picked to be the HK Collaboration of the Week. The previous HKCOTW was Kowloon-Canton Railway - see improvements.



Every week, a lacking Irish topic is picked to be the Irish Collaboration of the Week.
The current ICOTW is awaiting nominations!.
