Leading climate scientists are raising the alarm about global warming reductions, saying that limits to reduce sulfur pollution are actually exacerbating climate change. The sulfur-containing exhaust helps produce marine clouds that push heat back into space in the form of aerosols, but the oceans are still carrying the warmth and rising temperatures.

According to a new report based on three decades of satellite observations, sea level along contiguous US coasts could rise by as much as one foot above today's waterline by 2050. Scientists are hoping that these studies will help coastal communities plan for any kind of near-term flooding, whether it be catastrophic or minor. In part, global sea level has been rising for decades, owing to a changing climate. Scientists have struggled with predictions about how fast they will rise over time. The findings from NASA's Sea Level Change Team support the higher-range scenarios included in a big study released in February by several departments.

The first man to step onto the moon will miss a Nasa function to commemorate the landmark mission's 40th anniversary.
