Kelp locks up millions of tonnes of carbon globally, provides a nursery for fish and is a buffer against coastal flooding. But climate change, weather and fishing are taking their toll. Now, Mika Peck and his team at the University of Sussex are monitoring kelp off the south coast of the UK, to see if it can recover from the damage done to it by trawling and help improve biodiversity in the area.

Morning News: What A 3° Warmer World Looks Like, Sudan & Liverpool Let Go
It seems ever more certain that global temperatures will sail past limits set in the Paris Agreement. We examine what a world warmed by 3°C would—or will—look like.
Our correspondent speaks with Sudan’s three most powerful men; will they act in concert or in conflict on the way to democracy? And why Liverpool has been booted from UNESCO’s world-heritage list
Analysis: The Western U.S. Drought’s Major Impacts
Watering the Country’s Food Basket Is Becoming a Challenge
Droughts are part of a natural cycle of water. But the drought currently gripping the Western U.S. has climate scientists concerned that the cycle may be shifting. This has major implications for those who rely on the water the most: farmers and the communities they surround. Photo Illustration: Carter McCall/WSJ
Science: Avoiding Sudden Food Scarcity, Lattice Strength, Time Neurons
Addressing the problem of sudden food scarcity in US cities, and the up-and-coming field of computational social science.
In this episode:
00:45 Food shocks
Climate change, the COVID-19 pandemic, and geopolitical crises can cause food shortages. To tackle this issue, Alfonso Mejia and colleagues have modelled how to best mitigate these food shocks in US cities. Alfonso tells us about the new analyses and what steps cities could take in the future.

Climate: How California’s Drought Fuels Disasters
Each year, California and the Southwest break new records for droughts and high temperatures, leading to heat waves, wildfires, and even flooding. Learn how these catastrophes operate together—and how engineers are working on new technologies to help us survive.
Weather: Northwest U.S. 1000-Yr Record Heat Wave
With records broken in Portland, Eugene and Seattle, the Pacific Northwest is sweltering under triple-digit temperatures the likes of which has never seen before in the normally temperate month of June. Lilia Luciano reports. Jeff Berardelli also joins “CBS This Morning” to discuss more.
Future Of New Buildings: Benefits Of Using Wood
If we made 90% of our new buildings from wood, we could reduce our global CO2 emissions and improve our wellbeing, Tom Heap explains.
Views: Denmark’s $34 Billion Energy Islands
The energy islands and the wind farms with a combined capacity of 5 GW are expected to be commissioned by 2030.
The North Sea energy island will have an initial capacity of 3 GW which could potentially be further scaled up to 10 GW offshore wind. This will be an artificial island.
Finance: The $1 Trillion Market For ‘Green Bonds’
So-called green bonds have become more popular in recent years, and this fast-growing segment of the $128.3 trillion global bond market could grow even more. When an issuer sells a green bond, they’re making a nonbinding commitment to earmark the sale’s proceeds for environmentally friendly projects. That could include renewable energy projects, constructing energy efficient buildings or making investments in clean water or transportation. Green bonds fall under the wider umbrella of sustainable bonds, which include fixed-income instruments whose proceeds are set aside for social or sustainability projects. Big household names such as Apple and PepsiCo are diving into this space. A handful of massive banks and governments around the world are also issuing sustainable bonds, including China, Russia and the European Union. This may be contributing to the space’s rapid growth. A report from Moody’s said new sustainable bond issuance may top $650 billion in 2021. That would represent a 32% jump from 2020.
