An "all-time high" temperature record has been set in the US state of Alaska, despite much of the country sitting in the Arctic circle.

Farming in the shadow of the world's highest mountains has never been easy - and climate change is making it even more difficult.

Increasing temperatures, changing monsoon and more frequent extreme climate events are posing a threat to food security in India.

In the context of agriculture both crop modelling as well as statistical modelling approaches are used to assess climate change impacts. Studies comparing both approaches across developed as well as developing country context find little or no difference in their estimates.

Question raised in Lok Sabha on Impact of Climate Change on Ecosystem, 28/06/2019. In the pre-2020 period, India announced its voluntary goal to reduce the emission intensity of its GDP by 20-25 per cent from 2005 levels by 2020.

Current greenhouse gas mitigation ambition is consistent with ~3°C global mean warming above preindustrial levels.

This WWF briefing describes how climate change is impacting fisheries and food security, and highlights the European Union’s role in mitigating these impacts both for EU citizens and for developing countries.

Changes in precipitation totals and extremes are among the most relevant consequences of climate change, but in particular regional changes remain uncertain. While aggregating over larger regions reduces the noise in time series and typically shows increases in the intensity of precipitation extremes, it has been argued that this may not be the case in water-limited regions.

Crop yields are projected to decrease under future climate conditions, and recent research suggests that yields have already been impacted. However, current impacts on a diversity of crops subnationally and implications for food security remains unclear. Here, we constructed linear regression relationships using weather and reported crop data to assess the potential impact of observed climate change on the yields of the top ten global crops–barley, cassava, maize, oil palm, rapeseed, rice, sorghum, soybean, sugarcane and wheat at ~20,000 political units.
