Is climate change what brought winter storm Uri to Texas?

Mark Felix /AFP via Getty Images Winter Storm Uri scattered bitter cold, snow, and ice this week across a huge swath of the United States, including places that rarely see such extreme low temperatures. States like Texas with milder winters were caught off guard by the chill, which led to a massive spike in energy demand and a huge drop in available electricity as the infrastructure around natural gas, coal, nuclear, and wind energy froze up. Tuesday was the coldest day in North Texas in 72 years, with the Dallas-Fort Worth area reaching a record low temperature of minus 2 degrees Fahrenheit this week.

The New Humanitarian | Getting to the bottom of sea-level rise

In the past few months, newspapers across the globe have been flooded with a debate over new studies projecting a higher and faster sea-level rise by the next century, which would sound the death-knell for low-lying countries and coastal cities. The debate has been fuelled by varying interpretations of the impact of melting ice, and by a new projection of up to 1.4m in sea-level rise by 2100, rather than a 2007 projection by the authoritative Intergovernmental Panel for Climate Change (IPCC) of between 18cm and 59cm by that time, depending on a range of greenhouse-gas emission scenarios. The new projections in sea-level rise, caused by accelerating rates of loss from ice sheets in Greenland and Antarctica on account of higher global temperatures, even prompted the UN Environment Programme (UNEP) Year Book 2009 to warn that important tipping points leading to irreversible changes in major earth systems may already have been reached or passed .

Green construction - Building sustainable cities with wooden skyscrapers | Science & technology

ORE THAN half the world’s population dwell in cities, and by 2050 the UN expects that proportion to reach 68%. This means more homes, roads and other infrastructure. In India alone, the equivalent of a city the size of Chicago will have to be developed every year to meet demand for housing. Such a construction boom does, though, bode ill for tackling climate change, because making steel and concrete, two of the most common building materials, generates around 8% of the world’s anthropogenic carbon-dioxide emissions. If cities are to expand and become greener at the same time, they will have to be made from something else.
