ESA Euronews: When weather becomes climate / @esa

We constantly track our weather as it fluctuates day-to-day, but determining patterns over time can help us differentiate exactly when 'weather' becomes 'climate'.

Climate change may be visibly changing our world, but it cannot be charged with every meteorological peculiarity given the inherent chaos of the atmosphere. The only way to make sense of these changes is by looking for trends, and these days we have a perfect vantage point from space.

The world of weather watching is ruled by an armada of satellites, and Eumetsat in Germany owns and runs Europe's fleet of high-precision machines.
These hugely powerful devices are capable of mapping both high resolution temperature and humidity measurements, and different images of Earth in near real-time.

Thanks to these technological behemoths, we now know more about our weather than ever before; but understanding climate is a different matter.

Wood Reduces the Environmental Impact of Buildings / @reThinkWood

When evaluating building materials, it is important to consider their environmental impact across their life cycle. This video highlights how wood products have less embodied energy, are responsible for lower air and water pollution, and have a lighter carbon footprint than other commonly used building materials. Visit reThink Wood's website to learn how wood delivers more and has a lower cost to the environment.

The importance of the high seas / @WWF

WWF's Global Marine Programme is working to increase international attention for the conservation of vast expanses of ocean, and immediately protect the high seas. Around 64% of the oceans - an area covering half the planet - lie beyond the national jurisdiction of any country. Known as the high seas, these international waters are open-access common areas for everyone.
