trend), and I'm sure he or the other authors involved would have been happy to clarify anything else that might have come up.
Worldwide, vegetation fires are showing a
trend toward longer burning periods, increased fire severity, larger areas burned and increased (mostly human caused) frequency — with all of these factors contributing to more damaging environmental impacts, higher shares of
emissions and increasing socioeconomic costs,
including greater threats to human health and security.

emission trends that would result in concentrations continuing to climb.
On the energy /
emissions trends, we're about the only publication I know of that has given sustained, in - depth coverage to the glaring lack of energy research, the limits of current efforts (

trends related to the causes and effects of climate change.
While the NCA authors coyly admit that the region's «climate
trends include contributions from both human influences (chiefly heat - trapping gas
emissions) and natural climate variability» they are quick to add «[t] hey are also consistent with expected changes due to human activities.»

This
trend of rapid decoupling of
