Los árboles funcionan como aires acondicionados naturales.

Si los plantamos en lugares estratégicos en nuestras ciudades podemos reducir la temperatura hasta en 8ºC.

Hagamos de nuestras ciudades lugares más frescos, más verdes, más saludables y felices. Vía: @FAOenEspanol

🔍NEW DATA: Although Latin America lost more tree cover than it gained from 2015 to 2023, progress is being made.

🌲But that's not the whole story. For example, some gains in tree cover were mainly from increased plantations, which don’t always benefit the environment.

🚲 Giving up your gas car = 78x more emissions impact than composting
🌱 Eating less meat = 40% of the impact of full veganism
🏡 Solar + home energy upgrades = huge reductions

Everyday sustainable choices matter – to an extent. Transformative change = Governments + industry making these choices easier, cheaper and more accessible. More from WRI: https://t.co/98XHjUgC0V

Millions of people die prematurely from air pollution every year, as you can see in the chart.

This problem has existed since humans started burning materials for fuel — first wood and biomass, then fossil fuels.

But it’s an environmental and public health problem that we can make progress on. We know this because the world has already been successful in reducing air pollutants, and many countries that used to be highly polluted now have much cleaner air than they used to.

To tackle air pollution effectively — to focus our efforts on the interventions that will have the biggest impact — we need to understand where it’s coming from.

The core-periphery bifurcation of the world economy is not only real, but national governments are fully conscious of its reality. The North fights to maintain this violent system, which fattens their decrepit ruling classes, while the South fights to abolish it.

Solar is quickly becoming the cheapest source of electricity & will fundamentally change the energy system.

This paper argues that solar will be cheapest source of electricity around world. Surprisingly this is INCL short- & long-term storage costs.

Major carbon cycle feedbacks like permafrost thaw could amplify warming across this millennium. Even ‘safe’ emission paths may overshoot 2°C. The Paris goal is a physical limit, not a political choice. Today’s actions shape life on Earth for centuries.

We know how to build cities that don't cost the Earth:

✅ Nature-Based Solutions (green roofs, wetlands)
✅ Urban Green Spaces (parks, tree canopies)
✅ Sustainable Transport (bike lanes, e-mobility)
✅ Smart Planning & Community Action

New report by @WMO: 2024 was likely the warmest year of the past 175 years.

While a single year above 1.5°C of warming does not mean that our temperature goals are out of reach, it is a wake-up call.

2025 is a critical year for climate action.

Which countries have contributed the most to historical CO₂ emissions?

When we emit carbon dioxide (CO₂) into the atmosphere, most of it stays there for centuries or millennia. This means that CO₂ emitted even a century ago has contributed to the rising temperatures we see today.

In other words, how much the climate warms depends on how much cumulative CO₂ is emitted over time.

The chart shows the ten countries with the largest share of the world’s historical emissions, based on cumulative emissions from fossil fuels and industry since 1750.

The United States has contributed the most, accounting for almost one quarter. This is followed by China and Russia.
