According to the IPCC, the concentration of greenhouse gases in the earth’s atmosphere is directly linked to the average global temperature on Earth, and the concentration has been rising steadily. The most abundant greenhouse gas, accounting for about two-thirds of greenhouse gases, carbon dioxide, is largely the product of burning fossil fuels.
There is alarming evidence that important tipping points, leading to irreversible changes in major ecosystems and the planetary climate system, may already have been reached or passed. One of the most urgent challenges facing countries across the world today is how to achieve economic prosperity and development while also combating climate change.
The Paris climate change agreement commits nations to limit global temperature rise to no more than 2°C above pre-industrial levels, with countries pledging to cut or curb their greenhouse gas emissions – through a combination of mitigation and adaptation measures – by 2030.

The most influential climate science paper of all time
After the second world war, many of Japan’s smartest scientists found jobs in North American laboratories. Syukuro (Suki) Manabe, a 27-year-old physicist, was part of this brain drain. He was working on weather forecasting but left Japan in 1958 to join a new research project by the US Weather Service to develop a numerical model that could be used to study the climate.

Google Maps is to offer drivers the lowest carbon route for their chosen journey as part of the search company’s new environmentally friendly policies. Motorists will be able to select the route with the lowest carbon emissions once factors such as traffic and road inclines are taken into account. The new product launches in the US on Wednesday and in Europe next year. Where the comparable journey times are broadly the same, Google Maps will default to the lowest carbon option.
One of the issues for discussion at COP26 is global pricing mechanism for carbon dioxide emissions. Is carbon pricing an effective tool to reduce emissions and tackle climate change? What are the critical elements that determine its effectiveness?

Carbon pricing shows serious promise as a tool in the fight against climate change.
Deterring the use of fossil fuels, such as coal, fuel oil, and gasoline, is crucial to reducing the buildup of heat-trapping greenhouse gases in the atmosphere. Carbon pricing provides across-the-board incentives to reduce energy use and shift to cleaner fuels and is an essential price signal for redirecting new investment to clean technologies.
Less than one month to COP26. My colleagues at Earth Negotiations Bulletin will be reporting from Glasgow and have thoughts on what to expect, based on covering the UNFCCC talks in June 2021.

With two billion cups consumed each day, it makes coffee the most popular drink in the world. It's only natural to ask if and how the warming global temperatures affect coffee farmers and plantations. What does the future hold for coffee?
Countries’ current climate plans — including 2030 emissions-reduction pledges (known as NDCs) and legally binding net-zero targets — will only limit warming to 2.4 degrees C by 2100, setting the world up for increasingly severe wildfires, droughts, floods and more. If G20 countries fully enact the additional targets they’ve announced but not yet formally adopted, temperature rise could be limited to 2.1 degrees C.
New research by the WRI finds that if all G20 countries set ambitious 2030 emissions-reduction targets and commit to reach net-zero emissions by mid-century, global temperature rise could be limited to 1.7 degrees C in 2100, keeping the 1.5-degree C goal within reach.
If food waste were a country, it would be the third largest source of GHG emissions on the planet, of which 61% comes from households. Meanwhile, according to FAO, more than 800 million people are undernourished while 2 billion are micronutrient deficient.
In the lead up to the International Day of Awareness of Food Loss and Waste on 29 September, check out these 12 apps that help prevent household food waste and protect the planet.

According to the Guardian, 90% of coal and 60% of oil and gas reserves should remain in the ground if there is to be “even a 50% chance of keeping global heating below 1.5C”, the stretch goal of the Paris Agreement.
